- President & CEO
Thank you, Mark. Good afternoon, everyone. I would like to start by thanking all of you for joining us today on our third-quarter 2016 earnings call.
We continue to see robust demand for data and analytics solutions that provide visibility, analysis and insight into cybersecurity exposures, attacker behaviors and general IT challenges. This is especially true as more customers seek to optimize their security and IT spend, relying on data to help them prioritize their investments and measure the effectiveness of their programs.
Our third-quarter results show fundamental strength in several areas related to these favorable dynamics, including ongoing strength in our pipeline growth, solid growth in our mid-market customer base, new product adoption and uptake of our platform-based cloud analytics. Customers continue to see the value of are technically superior approach to security data and analytics.
We had solid performance in these areas and see healthy market demand. Nonetheless, total billings in the third quarter were below our expectations, primarily due to internal sales execution issues in two specific areas: larger deals in the enterprise sector and in the federal sector.
As we have mentioned previously, the timing of larger deals can be hard to predict and we manage this pipeline over a multi-quarter basis due to its variability. Most important, we have a highly differentiated product offering, a strong pipeline of opportunities in the enterprise sector, but we need to improve the effectiveness of our sales engine as we further scale this growth engine.
One of the meaningful changes that we've already made at the leadership level is creating the role of Chief Operating Officer and having Andrew Burton take on this role. His specific mandate is driving growth and execution across sectors while delivering significant increases in the leverage and efficiency of our go-to-market engine. In this regard, Andrew's focus will include re-aligning some of our top talent as we are making some critical hires.
More importantly, we are actively engaged in recruiting process to bring on new sales leadership experience in managing complex sale cycles as well as hiring sales talent with enterprise experience. We are taking quick action on these initiatives; however, I also know that it will take a couple of quarters to get our execution back to the necessary levels.
The second specific area in which bookings underperformed in Q3 was with our management of federal accounts. Last year we had particularly strong results within the federal sector, and in Q3 2015 we highlighted on the November 2015 call. While we had many opportunities in our pipeline this year, including some larger deal opportunities, we did not execute as we expected from a deal closure perspective.
While the federal sector does not currently make up a large part of our overall business, it did contribute to more than half of our billings underperformance in the third quarter. We believe these specific federal deals in the pipeline will materialize in FY17. As such, we are not planning for these deals to be included in our Q4 2016 results.
We are committed to building our market presence and relationship in the federal sector, which is part of the reason why we added key sales leadership rolls in late spring of this year. We have a clear understanding of our sales execution challenges. Both the larger enterprise deals and the federal sector benefit from strong demand, strong pipeline and strong product; and therefore, our focus is on expanding our leadership capacity, managing a large deal execution and ramping our new sales professionals.
These are addressable challenges over the next two quarters. There are many things going tremendously well in our business. As I noted a moment ago, we continue to perform well in the mid market.
Our investments in International expansion are continuing to play off as we grew our international revenue 69% year over year with solid activity in EMEA, LatAm and APAC. We also continue to grow our land and our expand, as we grew our customer base an impressive 33% year over year and our renewal rates came in at 121%.
Turning to our products and customer engagement. From a new product perspective, I'm very pleased with the progress we are making with InsightIDR and AppSpider, which together are now a meaningful portion of our bookings. We just finished our second full quarter with InsightIDR product offering in the market and the feedback from customers has been overwhelmingly positive.
The combination of our marketed leading user behavior analytics, a market that we helped pioneer, is now tracked closely by industry analysts, coupled with our advanced search and endpoint technology, is resonating with customers. Our platform is designed to allow us to quickly innovate, provide our customers an agile solution and respond to the full gamut of it incident detection and response challenges. Let me provide one of many similar examples of how we are able to provide customers with a full-service solution.
A telecom provider covering the mid-west needed to implement an overall security plan for their business as well as to ensure compliance standards were being met. This required bringing together multiple groups across the organization. Without a centralized IT group in place, it was a huge challenge for the customer.
With such a disparate and resource constrained organization, they did not have sufficient visibility into the assets on their internal network infrastructure. Our combined InsightIDR and Nexpose solution offerings, we were able to provide the detection, analytics and remediation path they needed with limited in-house support.
InsightIDR is performing well both in greenfield and replacement opportunities. We've often said that the SIEM market is going to an upgrade cycle, and we are seeing evidence of that trend. According to a recent Voice of Enterprise report published by 451 Research, SIEM was cited as the second-highest spending priority for info tech investments over the next 12 months.
Furthermore, our progress with InsightIDR, in terms of wins and pipeline build, has resulted in deeper engagements with large enterprises and gives us great confidence that we have a differentiated product offering. Historically, SIEM technology has been highly customized and very expensive.
Our InsightIDR offering is designed to help resource constrained organizations easily implement, operate and get meaningful insights into their risk and robust analytics. We believe we have designed an affordable alternative. The value we provide coupled with the depth and breadth of capabilities we can offer are giving us competitive advantage.
Another product seeing strong demand is our AppSpider offering, which targets modern web application threats. This continues to be a leading attack vector, and we believe our solution is proving to be technically superior to competitor products. In the third quarter, a Fortune 500 media content provider, who has a complex environment of 12,000-plus applications, including a multitude of micro services and APIs, deployed our AppSpider technology.
They previously had been having significant issues with authenticated scans, which are producing a high volume of false positives, as well as frequently crashing. The customer displaced its previous Fortune 50 provider, who was not able to deliver on the support and automation capabilities in favor of our AppSpider solution. Noting the ease-of-use of deployment of our technology, the customer also said they had accomplished more in three weeks with Rapid7 than in 18 months with their last provider.
In terms of the continued adoption of our Nexpose product offering, this quarter we displaced one of our closest competitors in a Fortune 50 retailer. The retailer has over 1,800 franchise locations and 250,000-plus employees. This was a large and extensive deployment as we needed to accommodate customized reporting around the SQL server database.
Our ability to scale and meet both their scanning and reporting needs was a key decision factor in this win. In addition, we are pleased with the adoption of our Insight platform, which is our cloud-based analytics capability leveraged both by the InsightIDR and Nexpose product offerings. Last quarter we shared that just over 12% of our customer base had adopted the platform.
In the third quarter that figure has risen markedly to 17% of our customer base, which represents more than 1,000 customers. This is important because this allows us to upsell and cross-sell more effectively over time while simultaneously lowering our cost of expansion.
As IT professionals continue to navigate the fragmented ecosystem, there is clear evidence that the demand for comprehensive solutions are coming into favor. During the third quarter, Rapid7 was recognized by the System Administration Network and Security Institute, better known as SANS, for providing the most comprehensive coverage across the Center for Internet Security Critical Security Controls for effective cyber defense.
The ranking found that we covered 19 of the 20 controls through our combined incident detection and response and threat exposure management solutions. Of the 19 companies listed, including Splunk and Tenable, no other company matched the depth and breadth of our robust product offerings or the technology capabilities in this ranking.
You can see why we continue to believe that we have the solid technology and customer engagement foundation to support continued growth in our business. Our differentiated solutions [live] on a single cloud platform provide a competitive advantage and position us very well in the data and analytics market. We continue to be committed to delivering on the three main objectives we set at the beginning of the year: disrupting the traditional SANS market, expanded that threat exposure management opportunity and driving scale and leverage into our business.
To help us continue to execute well on our vision, I'm happy to announce the recent appointment of our newest Board member, Judy Bruner. Judy is a seasoned executive with an impressive track record of operational excellence as both a company executive and board member. She previously held the role of Chief Financial Officer at both SanDisk and Palm.
We are excited to have her considerable skills and leadership as we continue to scale our business and execute our long-term growth strategy. We see significant demand for data and analytics solutions, both at the macro market level and at the Rapid7 product-centric demand level. We believe we have superior solutions built on a scalable platform architecture, and we remain focused on innovation.
We believe we are not only well positioned to displace the lagging incumbents but also win against the shrinking list of viable competitors in this space. It is all about execution and we are confident in our strategy, technology and, most importantly, talented team. There is a tremendous market opportunity ahead of us, and we believe we are well positioned to capitalize on it.
Finally, before passing the call over to Steven, I want to provide a quick update on the CFO search. We are very pleased with both the quality and the quantity of the candidates that we've seen in the past 90 days. We are in the final stages of completing the process, and we expect to have something to announce very shortly.
With that, I'd like to turn the call over to Steven.
- CFO
Thanks, Corey. Good afternoon, everyone. I'd like to start by providing some color around the business and reviewing our Q3 financial results and metrics, and then provide our guidance for Q4. Then wrap up the call, as we always do, by opening the call to your questions.
Reviewing our Q3 results, three financial highlights stand out as we continue to disrupt the SIEM market, expand the threat exposure management opportunity, and drive scale and leverage in our business. First, we delivered another quarter of compelling revenue growth north of 40% year over year, driven by our high visibility, highly recurring, ratable revenue model.
Second, we continue to make good progress on our path to profitability with another quarter of improving expense ratios. Third, becoming a consistent theme, we delivered another quarter of positive operating cash flow, which demonstrates our progress toward profitability on the strength and sustainability of our financial model.
Before we get into the details around these three areas, let me briefly comment on the billing dynamics that we saw in Q3. As Corey called out, our applied billings growth in Q3 was short of expectations with total billings increasing 10% year over year to $44.9 million. That results in a total billings increase of 28% year over year to $131.4 million for the first nine months of 2016.
The Q3 shortfall was due to two specific sales execution issues around our larger enterprise transactions and our federal sector deals. Importantly, we continue to see strong activity and pipeline generation for our Threat Exposure Management and InsightIDR offerings and for strategic advisory services.
As Corey also noted, we've already begun addressing the specific sales execution issues with concrete actions. Creating the role of COO and having Andrew specifically lead the mandate to focus and improve our go-to-market engagements, has also been a terrific evolution for Rapid7 and is already making a positive impact.
Turning now to the details around are Q3 financial results and the first highlight of the quarter, Q3 total revenue came in at $40.3 million, a strong increase of 42% year over year above the high end of our guidance. Products revenue increased 42% year over year driven by fairly consistent and good mix of both new customer logos as well as upsells and cross-sells within our base of existing customers.
Maintenance and support revenue grew 38% year over year, and our professional services revenue increased 49% year over year as customers continue to recognize Rapid7 as providing premier security assessment and advisory expertise. Importantly, we continue to have high visibility into our quarterly revenue results with 62% of our revenue gain recurring in nature and 87% of Q3 revenue already on our balance sheet in deferred as of the first day of the quarter.
Looking at some of the related dynamics contributing to our strong revenue growth, total deferred revenue grew 36% year over year in Q3 and was comprised of 41% year over year growth in short-term deferred and 25% and long-term deferred. Long-term deferred revenue growth was impacted by fewer large deals in Q3 that we discussed and by marginally shorter average contract lengths that came in at 21 months for total billings compared to 23 months in the previous quarter and prior-year period.
Another positive in the quarter was the strong year-over-year customer growth. Our total customer base increased approximately 33% as we ended Q3 with more than 5,800 customers globally. We now have 37% of the Fortune 1000 as customers of Rapid7 up from 35% a year ago.
As noted, we are having success not only with bringing on new customers but also with continued customer expansion as seen in our strong renewal rate of 121% for Q3. A related and important customer metric that we always share with you is expiring revenue renewal rate which measures our baseline customer revenue retention. In Q3 this expiring revenue renewal rate increased to 89% versus 88% in Q3 2015.
We see this illustrating two important dynamics for the business: high customer satisfaction and stickiness of our technology and product offerings. In order to help facilitate our continued geographic in the customer expansion growth, we initiated a focused effort a few years ago to expand our International business.
At the time we had less than a dozen employees outside of North America and single digits of our revenue from outside the US. Since then, we have grown our engineering, sales and go-to-market presence significantly in EMEA, Latin America and Asia-Pac, and this investment is beginning to pay dividends.
International revenue in Q3 grew 69% year over year and was 14% of total revenue for the quarter. To continue the momentum and further enable our sales teams to be well-positioned and competitive internationally, we continue to evolve our operating and go-to-market structure to provide greater agility and flexibility to engage with and support our global customers. In this regard we were pleased to successfully complete an off-shoring of our non-US intellectual property to our Rapid7 International subsidiary in the UK.
Previously all of our global customer contracts had been executed with our US entity. Our new global [IP] ownership and entity structure lays the groundwork for more nimble and flexible global expansion of the Rapid7 brand and footprint as well as a more efficient long-term tax profile and return to stockholders.
Turning back to this side of the pond, we delivered solid results in North America in Q3. Revenue grew 39% year over year and represented 86% of total revenue on continued growth and customer adoption. Our global channel partners continue to contribute to growth with 37% of total revenue in the third quarter, fairly consistent with past quarters.
With that, let's move to our second highlight for Q3. We are focused and continuing to be very thoughtful about managing our cost structure, making the necessary investments for growth while also driving a very deliberate and disciplined path to attaining profitability. In this regard, we were pleased to deliver another good quarter of non-GAAP gross margin, with Q3 coming in at 77%, an improvement from 76% in Q3 2015 and the result of some nice efficiencies that we're continuing to realize as we scale the business and continue to execute towards profitability.
This disciplined approach to improving are ability was also evident in our non-GAAP operating expenses in Q3, where the sales and marketing expense-to-revenue ratio came in at 49%, an improvement compared to 56% in the year-ago period and 55% in Q2. The improvement of the sales and marketing expense ratio are reflected prudent spending as well as benefiting from lower sales commissions in the quarter and still accommodated Q3 2016 royalty related to Intel MVM customers that were not in the year-ago period. As we mentioned previously on this front, there is some variability in the timing and magnitude of the Intel royalty expenses depending upon the source and timing of these deal closings.
While we continue to drive efforts to improve sales and marketing expense ratios year over year, we'd like to remind you that we typically see higher costs sequentially in the fourth quarter related to commissions on seasonally higher billings. As we will talk about in a moment, we are also forecasting marginally higher royalty expenses in Q4 related to Intel MVM customers.
Turning to R&D, our non-GAAP R&D expense was 25% of revenue in Q3 of compared to 32% in Q3 2015 and 31% in Q2. This continued improvement in our profitability is in large part due to great work that our products and engineering team has done and the dynamic where we now have nearly half of our R&D headcount outside of the United States.
We are also pleased that a portion of this improvement was attributable to a non-recurring $500,000 UK government grant received in the third quarter for our engineering operations in Northern Ireland. We're continuing to drive scale and leverage in our R&D investments, while at the time continuing to deliver important and differentiated features and functions across our core product lines. The power of our cloud-based analytics platform in terms of speed, agility and cost, is also contributing meaningfully to our efficiency gains, and we expect to see continued decreases in our R&D expense to revenue ratios in the fourth quarter and beyond.
Finishing out OpEx our non-GAAP G&A cost structure also improved marginally in Q3 coming in at 15% of revenue versus 16% in both Q3 2015 and Q2 2016. We expect to continue to improve our G&A expense profile over time.
Pulling this all together, Q3 2016 non-GAAP operating loss was $5.3 million, which was better than our guidance range for operating loss of $8.6 million to $7.6 million. Our non-GAAP loss per share was $0.13, also better than our guidance range of $0.21 and $0.19 net loss per share.
Turning to our third and final highlight for Q3, positive operating cash flow. We ended Q3 with a cash balance of $87.7 million, and our operating cash flow for Q3 was positive $1.8 million, a result of both our disciplined management of the business and the inherent leverage in our financial model.
With that, let's now turn to our outlook for Q4 and the full-year 2016. So far as our guidance for Q4 2016, we anticipate total revenue to be in the range of $42.2 million to $43.6 million. This equates to year-over-year growth of 31% at the midpoint.
We anticipate non-GAAP operating loss for Q4 to be in the range of $11.7 million to $10.7 million. We anticipate non-GAAP loss per share for Q4 2016 to be in the range of $0.28 to $0.26. This is based on anticipated 42 million weighted average shares outstanding.
As result for full-year 2016 guidance is updated as follows: We expect total revenue to be the range of $154.6 million to $156 million, higher than our previous guidance and representing 41% year-over-year growth at the midpoint.
We anticipate an improved non-GAAP operating loss for the full-year 2016 to be a lower loss in the range of $35.5 million to $34.5 million. We also anticipate an improved non-GAAP loss per share for the full-year 2016 to be a lower loss in the range of $0.87 to $0.84. This is based on an anticipated 41.4 million weighted average shares outstanding for 2016.
With that while we have not provided guidance on billings historically and we don't currently plan to change that going forward, we did want to provide some additional color on Q4 billings given the work that we're doing around our execution, as Corey discussed on the sales side. While we're confident in the changes that we've already made and the contributions that Andrew, for example, is already driving in the newly created COO role with our go-to-market approach, we anticipate this taking a couple quarters to work out. As we implement our action plan in the near term, we expect Q4 billings to be in the area of approximately $58 million to $60 million.
Finally, let's talk about operating cash flow. We previously said that we expect to generate approximately $10 million in positive operating cash flow in 2016. Despite the Q3 sales execution challenges and tempered Q4 2016 billings expectations, we still expect positive OCF for Q4 and the full-year 2016.
Lower billings, though, means lower cash collections, and so we would anticipate OCF to be in the range of positive $4 million to $5 million for the full-year of 2016. Operating cash flow is a meaningful proxy of our path to profitability and the power of the financial model, and, importantly, we expect to see a multiple expansion of positive OCF in 2017 as we continue to scale the business and see leverage in the model.
With that, we appreciate your time and support and as always, we are glad to open the call for any questions. Operator?

Rob Owens, Pacific Crest Securities.
- Analyst
Great and thanks for taking my question, guys. As you expanded your value proposition from VM into more the broader-based analytics SIM type of play, can you talk about what that's done to sales cycles. And as you've look at some of these larger deals pushing out, have these been more around the VM space or have these been customers that are buying the larger vision and package from Rapid7, and as a result you're just seeing larger sales cycles?
- President & CEO
We are definitely seeing -- this is Corey, we are definitely seeing some longer sales cycles. What I'll highlight is primarily focused on larger deals in general and what we found, as we've escalated the volume of larger deals that we do over a year, it's just inconsistent.
In Q2, we had a much higher volume of larger deals and closes than we expected and in Q3 it was less. And so we find is that as we expand our footprint into larger deal enterprise segments, we just have greater volatility around the closing offering and therefore, we are paying closer attention to the length of the deal cycle. But in Q3 specifically, we did see a longer deal cycle than we expected.
- Analyst
And are you seeing capacity issues on the front, Corey? I know you've been reluctant to add a ton of heads that were more so on the direct side and so have more of an indirect kind of channel bend to the model. So as you look at more large deals potentially in the pipeline moving forward, will you add incremental sales capacity?
- President & CEO
One of the things we are very focused on is both adding expertise and leadership that's focused on large deals and enterprise sector but also adding the right head count. But doing it in a way that allows us to continue to get scale and leverage our profitability off the business.
- Analyst
Then lastly for Steven, real quick, on the Intel MVM piece, any kind of update in terms of how penetrated you feel you are into that base, and how much longer you should begin to see benefits or when it should impact the numbers? Thanks.
- CFO
Sure. Thanks Rob.
No material changes in the business, it continues to move forward well. It is the same cycle, if you will, so far as the longevity of the relationships with the customers. We just see a little bit of the pressure, if you will, from doing a large amount of deals with Intel means a little bit higher commission rate in the short term, but higher-marginal productivity.
Because the key point was that we're finding customers who take maybe a little bit longer to come over, a little bit more work, if you will. But when they come over they're usually coming over at a multiple of their run rate bookings. They take a long time to do something and then when they do, it's a more meaningful number.
So that's good news. But what we wanted to make sure everyone understood also and consistent with what we said in the past two quarters, is that means a little bit higher commission on the OpEx side.
- Analyst
Great, thank you.
Operator
Michael Turits, Raymond James.
- Analyst
Corey and Steven, can you drill down a little bit more on exactly what happened with those deals, especially since you sounded like you do have some visibility, that you said they wouldn't close in 4Q, but expect it the next year. So I assume they weren't a competitive loss -- what was the nature, the reason for this slip?
- President & CEO
Absolutely. So we talked about two specific parts of the large deals that were challenging in Q3. On the first side the federal sector deal, those pushed, they pushed into FY17. Because as you know, the federal sector, you go through the budget cycle again. So it is prioritized, it's in the budget cycle, but it's in the budget cycle for this coming year. So we have low expectations about the push deals closing in the federal Q1, which is our Q4. So that's the first part of the equation.
On the second part, as I just mentioned, what we found is that we have had volatility in the enterprise sector on very large deals, and we've talked about this before. We saw with them close much faster in Q2, and we saw lengthening cycles in Q3, and so therefore more conservative on Q4. Some of the deals that we've projected in Q3 have already closed coming into Q4. But until we get a better execution capability on managing the increase in volume with large deals, we're being more cautious about how we look at forecasting those deals.
- Analyst
I know you're not obviously giving guidance on 2017 right now, but you've got a Street number for sales that's in the mid 190s range. So at this point, would you expect these kinds of delays to be in execution around large deals to be a significant enough that would begin to impact revenues and our expectations for them in 2017?
- President & CEO
So Steven and I will tag-team it. So we are a growth business and we expect to address the large deal execution issues, and then after that period, continue to grow from there. So that's our expectation going into the year.
And the nice that we have is we have a strong demand environment and we believe that we can address those issues. Then, I'll tag-team with Steven about how we actually think about guidance and when we will give it for 2017.
- CFO
We will give -- Michael, so spot on, very appropriate and reasonable question. And it's something that we obviously work through. The nice part, as Corey mentioned, is the model on average if you look at a two-year booking, the impact in any given year is muted per se of the weaker billings performance this quarter, but it does have some impact going forward.
So we'll give more guidance on that on the February call full view of 2017 on the revenue side for sure. It'll have some impact in the short term, but we obviously are focused as well and we gave a little bit of color today on the more important candidly impact, or at least equally important around the path to profitability. And we see a multiple gainer in profitability in 2017 and we continue to feel really confident about that.
- Analyst
Thanks.
Operator
Gregg Moskowitz, Cowen and Company.
- Analyst
Great, thanks very much and good afternoon guys. A bit of a follow-up on the sales execution. I was wondering Corey, as you say, the market demand environment is still strong. But are these newly surfaced issues in your view, I do think that possibly they were sort of latent or existing for a little while, but your opportunity has been so significant that you didn't perhaps really notice them until now? Just acing the deal for what happened in Q3?
- President & CEO
I would say that it is very clear for a while, we talked about this consistently that we have volatility in our larger deals. We saw that in our commentary in Q1 and in Q2.
We saw extremely positive benefits from that volatility in Q2, but the extension was much more than we expected in Q3. So with that, we are actually taking the time to really go to the core and address the execution issues directly and ensure we actually have the right team and people and processes in place so that we can actually have tighter bands about how we manage that business on an ongoing basis.
- Analyst
Okay, got it, thanks Corey and then Steven just getting back to duration. I wanted to ask about that because if you look at the shortfall, a lot of it didn't appear to occur because of long-term differed and in fact, short term billings grew by 25% year-over-year. You talked about duration being two months shorter than what we've seen last quarter and a year ago. Can you give us just a little more color on both duration for both new deals, as well as renewals this quarter?
- CFO
Yes, sure. You did a nice summary of all the dynamics. So new was about 25 months new bookings, weighted average contract month, whereas renewals was 15, the average of which is about 21. So how that compares year-over-year is that the 25 months on new compared to 26 last year, and so that's not phenomenally different, a month shorter, but a month is a month, it does pull it down a little bit. The interesting comp though is, if you recall, from last Q3, last year's earnings call, we did have a bunch of interesting dynamics that we candidly didn't a talk about a whole lot now, but we had some over performance in our bookings that really drove deferred revenue.
We had a really nice federal deal that was very large, we had a really large transactional business impact on the business and as well, we had a big renewal, if you go back and look. And that large renewal in Q3 of 2015 took the renewal weighted average contract up to 19 months last year. So that's why when we look back at Q3 of 2015 and we had total bookings growth of 63%, we talked about the year-over-year growth as being a tough comp, it is the 19 and renewals that brought the average up to 23 last year versus 21 now.
- Analyst
Okay, very helpful, thanks for the Steven. And just one last question if I could, and again I realize, to Michael's question as well, you're not going to give, understandably, lot of granularity on 2017. However you did make a comment that you expect OCF to effectively go with a multiple of what you're seeing in 2016. And if I look at the billings guidance for Q4, that implies a second half of 2016 billings growth of 11%, 12% or so. And so the question is, again, without you getting hard granular guidance, if you do expect a meaningful acceleration in your billings growth in 2017 versus your second half 2016 levels?
- CFO
Sure, sure. We'll, as always, tag-team, Corey and I both. Mathematically and importantly, the second half 2016 dynamic is as you said the guidance on what we feel. And candidly, it's looking at Q3 of as being lower than certainly we had anticipated and desired. And so we see that -- I don't know if low watermark is giving it enough import that that's as low as it would ever get. And so we see that starting to come back in Q4 as we started taking action and see continuing to get back to levels that we are accustomed to seeing with the business.
- President & CEO
Absolutely. If you-- look, Q3 was lower than expected. We are taking management action to focus on action around the larger deals in Q4. So therefore we remain thoughtfully cautious there. But we expect that over the next two quarters for that action to have impact and for us to be growing stronger than you see in a second half of this year in the guidance that we laid out.
- Analyst
Okay, great. Thanks very much.

Great. Thanks for taking my question. Corey, you talked about the realignment of top sales talent that you are hoping to do to help mitigate the volatility in the enterprise business. Can you maybe just detail how you think that's going to help execution? And then related to that with the new COO on Board, what kind of steps is he taking specifically to better mitigate the volatility moving forward?
- President & CEO
The good thing we have going for us is that most of the businesses is working quite well. Whether you look at mid market, international or our new product execution, it is fairly localized to the larger deals. And specifically what we're doing is we are bringing in sales leadership that has experience managing the volume that we are now getting to in larger pipes and larger transactions. And I really see that as a two-part effort is -- we're going to continue to add headcount that has experience there. And we will add new processes about how you manage the volume of larger deals in pipe that we have.
And traditionally, lots of our growth has not come, as we talked about before, from the larger deals in the enterprise sector. It's come from the mid market and that's been, how you say, it's an additional upside and a sector expansion. But we're now at a place where we have enough volume of pipe there, that will bring in expertise that experienced at managing large deals with the volume that we have in that sector.
- Analyst
Okay, got it. It then a question on McAfee. Steven, you talked about customers coming over and they are coming over a multiple of maybe what they were at McAfee. To what extent is this due to customers evaluating and implementing InsightIDR and does that perhaps lead to maybe longer sales cycles? Is it there looking at that solution and maybe comparing it to a traditional SIM that they've already implemented and seeing if it is something that they can replace?
- CFO
Sure. Good question. The answer is, in a nutshell, no. The IDR component is not elongating contracts. What we're finding is that customers are engaging around the core: Threat Exposure Management, VM aspect and getting that in wraps. And then we are having conversations and continuing the dialogue around the whole Incident Detection and Response portfolio. But that doesn't seem to be impeding contract closing.
- President & CEO
Especially around the McAfee MVM. The nice thing we have is that we do expect it and we just want to be more predictable at it, to impact the deal cycle, but we have more and more customers that are looking to standardize on our platform. And that's a good thing as long as we actually manage our ability of to actually forecast the timing well.
- Analyst
Got it, thank you.

Jonathan Ho, William Blair. It would appear Mr. Ho disconnected.
Matt Hedberg, RBC Capital Markets.

Thanks for taking my question, this is actually Matt Swanson on for Matt. I was just curious, as you're moving more into some of these larger enterprise deals, are you seeing anything different in terms of competitive dynamic? It sounds like most of the challenges this quarter were internal. I'm just curious of your thoughts on that?
- President & CEO
I would say that we have not seen any difference in the competitive dynamics over the course of the last year in the enterprise sector. The biggest thing we talked about before is that we continue to see people upgrading their SIMs. We continue to see strong demand for visibility and products that deliver visibility and insight into the market. So we look at this as really just focusing in on how do we actually manage a growing pipeline and do that well with higher predictability.
- Analyst
Thanks and the just one more on the talk around hiring and adding more headcount to the sales force, or at least at the management level. We've heard from other companies this is kind of a tough, competitive hiring environment for those types of positions right now. I'm just curious your thoughts on that and if that could affect are long it takes to get a couple of these things straightened out?
- President & CEO
I think it is a very good question and there is definitely a tight hiring environment for experienced sales leaders. Since we are active in the process right now and we've been looking, we are very well-positioned, I think, to actually close a strong candidate in a reasonable timeframe. So you will hear more from us about that later. But we're feeling very good about our progress on that search right now.
- Analyst
Alright, thanks for the time, guys.

Jonathan Ho, William Blair.

Hi. Sorry about that. Just wanted to touch base in terms of what you guys are seeing in terms of public cloud adoption and is that having any negative or positive impact on your business as enterprises start to contemplate the public cloud?
- President & CEO
It is a great question. So in general we see more companies open and willing to shift to the public cloud. I think the two exceptions, which were planned in our model, which aren't surprises, are the federal sector and governments around the world are taking a more cautious approach, although they're opening up avenues for them to be able to adopt cloud technologies. And the second thing is that there's higher scrutiny outside of the US and so we've had to open up data centers in other countries around the world. But we are pursuing those strategies right now, but that's expected.
- Analyst
Got it and then can you talk a little bit more about the IDR and [TEM] pickup in terms of cross sell that you saw this quarter and maybe how you can continue to accelerate that adoption over time?
- President & CEO
The big thing that we're looking at this year is that we had a great introduction. We launched InsightIDR and was it going to get the critical mass passed? What we have seen clearly, is that it has gottent the critical mass passed. We're able to sell it, drive traction and adoption. And we've nicely been able to actually split that adoption between our existing customer base, which represents expansion, as well and bring in net new customers into (technical difficulties).
So as we look forward, we are really looking out for next year about how do we optimize the efficiency and that costs around that expansion and that's our big focus. We know it works, we know customers have strong demand for the offering, and so really honing and focusing our go to market model next year, where we actually have a full-year of all of our products around the land and expand strategy in place.
- Analyst
Got it. Then one final one for Steven. As we start to think about 2017 and operating leverage in the model, how should we balance of this with also the need to invest and maybe some of these sales execution challenges. How should we think about that that? That leverage especially, just given some of the challenges on the booking side?
- CFO
Sure. So the confidence that we get the model is really driven off of what you said, which is the leverage that we get from an operating and infrastructure standpoint, meaning our R&D and G&A, if you're going to pick on line items, and candidly on COGS as well for the most part.
Where we see that really as a step function investment and return profile, so there are no meaningful investments that we see needing to make in any of those areas in order to drive continued growth, both from a scale standpoint getting the growth and B, from a leverage standpoint and getting more out of that marginal growth.
So the efficiency comes out of those areas immediately and we see that in the OpEx, E to R, expense to revenue ratios, and then that is a big driver of the higher marginal OCF contribution. Sales efficiencies we also continue to expect to see. As you noted and as we've been pretty candid, we had some challenges this past quarter and will work through those. And so that will still be better, but it may not be as robust insofar as how to think about looking at that for next year.

Great, that's helpful. Thank you.

Saket Kalia, Barclays.
- Analyst
Hi guys, thanks for taken my questions here and I'm sorry, I ended up popping on late.
- President & CEO
No worries.
- Analyst
First, apologies if you've already spoken about this, but maybe just starting with the bread-and-butter midmarket TEM business. Can you talk about, qualitatively, of course, how is volume of deals and pricing versus maybe what you've seen in the last couple quarters. I want to ask but enterprise, because clearly that is a focus, but I want to start in that bread-and-butter midmarket business first.
- President & CEO
As I talked about little bit earlier, one of the things that we are quite pleased with is we strength midmarket, our traditional business in that mid enterprise business, and we see that across products and across all aspects of the business. So that is a healthy strong business, which gives us confidence as we look forward.
And it also gives us a clear focus area that as we address are large deal enterprise specific issue that we'll continue to be able to leverage the strong execution that we continue to see both our mid enterprise international and our new product business.
- Analyst
Got it, got it. And then just to clarify, what was the bigger driver of the delta? I know we said enterprise and federal, but was their one that was a little bit bigger than the other just to start out?
- President & CEO
From an impact, federal in Q3 was definitely a bigger driver in the GAAP versus what the potential was that was there. And that's mostly just because that is the federal close cycle. And so when you have lots of deals that are in hype, you have a smaller volume to close, you just have a much higher impact [than Madere].
However, there was a smaller impact because we saw, again, continued volatility in the large deals in the enterprise sector close rate in Q3 and those deals elongated past what we expected. We are taking a more cautious approach to Q4, but more importantly, we decided to go ahead and focus on the fundamentals of both the -- ensuring we have the right people and process for those large deals in place
- Analyst
Got it and maybe if I can just slip this in. That idea of taking a more conservative approach to Q4 probably implies some of those larger deals, assuming they haven't slipped out of the pipeline. What would actually happen in 2017. I guess that would imply an enterprise sales cycle over six months and correct me if I'm wrong. The question is, how does that sales cycle maybe compare to what you've seen from enterprise customers that you've sold to in the past?
- President & CEO
Absolutely and I think this is one of the things that we are paying careful attention to. So if you think about, and we've talked about this before, our average sales cycle is closer to the 90-day range. And we have seen our larger deals have a wide range of deals there. But we've also seen a fair amount of those because they have a wider range be closer to the under six months mark.
However, we know from experience both here and other places and from lots of peers that we actually talk to that the average larger deal enterprise sales cycle is in the six to 12 month range. So as we have large volume of deals it is not unreasonable that we actually have reverted to the norm, or reverted to the mean on those. And so that something we actually pay careful attention to. Which is why I talk a lot about the predictability of how we actually manage and forecast those larger deals.
- CFO
Yes, and Saket, to Corey's point, we talk about this a lot, the nature of the model, the averages almost don't really exist in nature, because it is the two models of a high transaction volume business that you asked earlier and the larger deal enterprise business. And so the deal cycles for that high transaction volume business are more like 60 to 70 days and has been chugging along really nicely, fairly consistently for the last two years, probably, in that zip code. Then to the whole discussion here, certainly the nature of the market and increasing scrutiny on the part of purchasing, but then also this quarter specifically for us, our own internal need to look inside the sales cycles for enterprise for larger deals, North of that 250k zip code, that could be five to eight months. So that's where that 90-day average comes from, but it doesn't really exist in nature.
- Analyst
Got it, very helpful. That's it for me, thanks, guys.
