Mark McLaughlin - Chairman, President and CEO
Thank you, Maria, and thank everyone for joining us today.
I'm delighted to be here to share with you our achievements in the fiscal first quarter of 2013.
Palo Alto Networks is transforming network security, and our clear technology differentiation continues to drive our growth.
Customers globally are recognizing the benefits of our solutions to solve their pressing network security needs, and this is reflected in our growth, which continues to significantly outpace the industry.
Today, I would like to outline some of the progress we've made in recent months, which includes a strong first quarter with record revenue; the addition of over 1000 new customers in the quarter; and hosting our first-ever user conference, where we further extended our technology lead with multiple product introductions.
On the financial side in the first quarter, we generated record revenue of approximately $86 million, which represents 50% year-over-year growth and approximately 14% sequential growth.
We also demonstrated continued growth in operating leverage and delivered non-GAAP EPS of $0.04 per diluted share.
On the customer side, we continued to focus on our land, expand, and extend strategy to drive results and fuel our growth.
From a land perspective, during the first quarter, we added over 1000 new end customers, bringing our current customer count to over 10,000 total end customers.
This is the fourth consecutive quarter in which we added over 1000 new customers.
And on the expand and extend side, our customer lifetime value continues to grow, as evidenced by the lifetime value of our top 25 customers increasing to 9.9 times their initial purchase, up from 9.5 times last quarter.
Some examples of wins in the field in the first quarter were in a competitive bid against Checkpoint and Fortinet.
We landed a new deal at a major European telecom operator, where we're replacing Checkpoint firewalls and McAfee's IPS for internal IT systems protection, as well as replacing Juniper and TippingPoint for their MSSP business.
Additionally, we became the primary firewall for one of the leading European broadcasting companies, replacing Cisco and Juniper in a multimillion dollar transaction.
And for this customer, we also provided them with our real-time threat prevention services.
We also expanded our relationship with a very large US government agency.
At this agency, we won the data center IPS business about five quarters ago at one location.
And this quarter, we expanded our presence to all their data centers throughout the United States for IPS and firewalls.
We replaced McAfee and beat Sourcefire for distributed security at a global health and beauty company based in the US.
And finally, on the extend side, one of the leading lifestyle media companies in the world deployed us as a data center IPS solution six quarters ago.
In the fiscal first quarter, we expanded our presence as a customer deployed us as their global data center firewall replacing Cisco.
Also in November, we hosted our first-ever user conference, Ignite, where we had close to 1000 attendees from over 500 companies and 25 countries.
It was exciting and validating to hear repeatedly from our customers that we're helping them to solve their security problems with unmatched solutions.
The message from our customers that resonated loud and clear was that our solutions are clearly unique in the marketplace, as no other competitor is able to safely enable applications.
At Ignite, we also launched four new products, all of which address today's virtualized and fiscal enterprise networks and further extend our technology lead over the competition.
First, we launched two new hardware platforms that will address identified opportunities within the enterprise -- the PA-3000 Series, which is a mid-range next-generation firewall, and the M100, which is an easy-to-deploy, high-performance management appliance for our Panorama management system, that introduces distributed log collection capability for large-scale enterprise deployments.
This launch represents a significant step forward for our management tools.
Also, we introduced our new VM-Series, which is a virtualized next-generation firewall platform that brings next-generation network security into the virtualized data center environment.
We believe virtualized security will become increasingly as important as more core applications are run in virtualized environments.
And we intend to be a leader in this emerging space.
We launched the VM-Series in collaboration with VMware to provide our shared customers the ability to address their security and compliance needs while accelerating their adoption of virtualization.
We also formally launched WildFire, our subscription-based -- our subscription cloud-based modern malware detection and prevention service.
This new service gives subscribers one hour response times for the delivery of modern malware signatures and integrated on-box logging and reporting.
To date, WildFire has discovered more than 70,000 new malware files that had not been identified by existing anti-malware solutions.
And the enhanced response will ensure that the damages caused by zero-day malware and targeted attacks are mitigated for our customers.
WildFire does not only detect modern malware, but for the first time, enables enterprises to prevent malware.
All of our newly unveiled products are supported by the release of PAN-OS 5.0, which has more than 60 new features focusing on solving unique network security problems in cloud environments, scaling and simplifying network security management in large enterprise environments, enhanced IPv6 capabilities, and increased control for managing the growing amount of SSL traffic in the enterprise.
Increasingly, we are becoming a partner of choice for other leaders in the technology world.
We announced a new multiphase relationship with Citrix that starts with validated joint solutions for their virtual application and desktop virtualization solutions, as well as other -- as well as popular enterprise applications.
Separately, we added nine other leading companies to our technology partner program, including RSA, SafeNet, and Skybox Security.
Security remains a top priority for CIOs around the globe.
In general, we see that security spending is resilient, even in a challenging macroeconomic environment.
We believe that there will continue to be significant displacement security spending among spenders, with the market favoring the next-generation technologies that provide significantly better security, and at an increasingly better value.
As we look forward, we will continue to be aggressive in maintaining our technology advantage, increasing our market share, and ensuring the highest levels of customer satisfaction.
With that, I'd like to turn the call over to Steffan for a detailed look at our financial results.
Steffan?
Steffan Tomlinson - CFO
Thank you, Mark.
And thank you all for joining us today.
I'd like to mention that, unless specifically noted otherwise, we are discussing all numbers except revenue on a non-GAAP basis that excludes share-based compensation expense, and where relevant, its tax-related effects.
In Q1 '13, total revenue grew to a record $85.9 million, an increase of 50.5% over a very strong Q1 '12 and 13.6% sequentially.
In Q1 '13, product revenue of $55.5 million grew 29.5% year-over-year, and 12.3% sequentially, driven by sales of our series of appliances.
Services revenue, which is comprised of both subscription and support, up $30.4 million, increased 113.4% year-over-year and 16.1% sequentially.
Services revenue accounted for 35.4% of total revenue, an increase of 80 basis points sequentially.
This is in line with our expectations, and underscores the power of our hybrid revenue model as it provides enhanced visibility.
The geographic mix of revenue was 64% Americas, 23% EMEA, and approximately 14% for Asia-Pacific, with all theaters posting growth on a year-over-year and sequential basis.
Total non-GAAP gross margin in Q1 was 72.6%, in line with our target range.
Non-GAAP gross margin decreased 160 basis points year-over-year and increased 70 basis points sequentially.
Q1 non-GAAP product gross margin was 74.2%, down 180 basis points year-over-year and 60 basis points sequentially.
The sequential decrease was primarily due to product mix.
Looking forward, product gross margins will fluctuate as we introduce new products, such as the PA-3000, which was introduced in November.
New products have a higher initial cost of goods sold, but will improve over time as volumes increase.
Our non-GAAP services gross margin was 69.5%, up 60 basis points year-over-year and 290 basis points sequentially.
The sequential increase was primarily due to the timing of headcount of project-related expenditures in the quarter.
Services gross margin will also fluctuate, depending on the timing of the ramp of our service organization.
Moving on to operating expenses, we continue to invest in product development, and expand our sales and go-to-market organization.
Q1 '13 non-GAAP R&D was $11.6 million, an increase of $1.4 million from the prior quarter, primarily related to spend on programs and headcount additions.
As a percentage of revenue, non-GAAP R&D expense was 13.5%, flat with Q4 '12.
Q1 '13 non-GAAP sales and marketing expense was $38.3 million, an increase of $2.8 million from the prior quarter.
And as a percentage of revenue, it was 44.6%, a decrease of 230 basis points sequentially, primarily due to operating leverage.
Q1 '13 G&A expense was $7.2 million, an increase of $0.8 million from the prior quarter, or 8.4% as a percentage of revenue, flat with Q4 '12.
In total, Q1 '13 non-GAAP operating expenses were $57.1 million or 66.5% of revenue, an increase of $5 million or 9.6% from the prior quarter.
Moving on to operating margin, in Q1, we saw a strong increase in non-GAAP operating margin, which grew 300 basis points sequentially to 6.1%.
The sequential improvement in operating margin this quarter can be attributed to continued natural leverage as we scale, as well as timing of headcount additions.
As we've stated previously, our goal is to grow operating margin in a steady manner, but we've also noted there will be near-term fluctuations.
Our non-GAAP effective tax rate for the quarter was 42.6%.
This rate will continue to fluctuate throughout the fiscal year, as it's dependent on our global pre-tax profit mix and potential discrete events, such as the removal of our domestic valuation allowance.
Non-GAAP net income for Q1 was approximately $2.9 million or $0.04 per diluted share, using 77.8 million shares.
This compares to non-GAAP net income of $1.9 million or $0.03 per diluted share in fiscal Q4 '12, and non-GAAP net income of $5.6 million or $0.01 per basic and diluted share in fiscal Q1 '12.
On a GAAP basis, net loss was $3.5 million or $0.05 per diluted share on a basic and diluted basis for Q1 '13.
Turning to the balance sheet, we finished October with cash, cash equivalents, and investments of $342.1 million.
In Q1, cash flow from operations was $23.1 million; free cash flow was $19.1 million; and free cash flow margin was 22.2%.
Cash flows benefit from our hybrid revenue model in which we bill for our services at the beginning of the engagement, and we collect the cash shortly thereafter.
We ended Q1 with $56.4 million of accounts receivable, up from Q4 '12 balance of $45.6 million.
Average days sales outstanding were 53 days, in the middle of our target range of 50 to 55 days, and up modestly from 50 days reported in Q4 2012.
Moving down the balance sheet, our hybrid revenue model helped increase total deferred revenue to $160.4 million, an increase of 86.2% year-over-year and 18.1% sequentially.
Short-term deferred revenue of $101.4 million increased 17.5% sequentially.
While we're continuing to see an uptick in multi-year deals, the majority of our services engagements are on an annual basis.
Let me now turn to our guidance for Q2 2013.
We expect revenue growth to accelerate on a year-over-year basis and be in the range of $90 million to $94 million.
This equates to 59% to 66% year-over-year growth.
Additionally, we expect non-GAAP EPS to be approximately $0.04 per share, using 78 million to 80 million shares on a diluted basis.
With that, I'll turn the call over to the Operator to open the Q&A session.

Greg Dunham, Goldman Sachs.
Greg Dunham - Analyst
Thanks for taking my question.
I guess, first question, a common question I get is, how often is Palo Alto used as the primary firewall vendor?
You kind of highlighted a couple of wins there and you also noted that -- the 9.9 statistic from existing customers.
But can you address that concern from some investors and how that's progressed over time?
Thank you.
Mark McLaughlin - Chairman, President and CEO
Sure, Greg, it's Mark.
Yes.
So, we've said before that we were on the road example that about half of our installations, we are the primary firewall, and more than half of our new sales, we're the primary firewall.
So I think what you're seeing in our results here is -- plus the lifetime value statistics reporting -- is that more and more often, we are the primary firewall, either in the initial sale, and specifically when we're already in an account, that is happening more and more often as well.
So that is trending in a positive direction for us, where we are becoming their primary firewall.
In installations, we're already being put into a company and more of our new sales are primary firewall as well.
Greg Dunham - Analyst
Thank you.
Operator
Keith Weiss, Morgan Stanley.
Keith Weiss - Analyst
Thank you for taking my question and nice quarter.
I was just wondering if you could give us a little more color into the environment?
And in particular, two areas, one the federal government.
I know you guys had a really good year last year in federal government.
I just wanted to see how it turned out this year?
And maybe give us a little visibility into what you guys are thinking about the fiscal cliff, and whether that's going to impact you guys at all?
And then maybe a little bit on EMEA.
It looks like EMEA, you got a nice bounce back there, and -- or a nice balance there in terms of growth.
The absolute revenue number from Q4 into Q1 -- how are you guys feeling about EMEA, given the current macro over there?
Mark McLaughlin - Chairman, President and CEO
Yes, sure, Keith.
Let me start with the highest level question on the fiscal cliff, which is, it's really uncertain to say what kind of impact that would be.
I think from a -- you know, if it was going to be a big impact, probably it'd be more in the government space, if there was sequestration and things like that.
And the main impact of that sort of thing primarily would be at the end of the year for the Fed, which has gone by.
So there's quite a bit of time for everybody to get all that stuff worked out.
That sort of macro condition aside in the Fed space, for us, that continues to be a very strong vertical for us.
We expected a strong quarter from the Fed as usual in Q1, and it performed to our expectations.
All that aside, still no vertical accounts for more than 15% of our overall business.
And we're still very nicely diversified.
And then from the EMEA perspective, we continue to keep our eye on that, like a lot of companies do, particularly in Southern Europe.
But that region for us had very strong year-over-year performance.
And also we had good strong sequential growth in EMEA this quarter as well.
Keith Weiss - Analyst
Excellent.
Thank you, guys.
Operator
Phil Winslow, Credit Suisse.
Phil Winslow - Analyst
Good quarter.
You had a particularly strong number in deferred revenue this quarter.
Wondering if you could just comment on the trends that you're seeing, in terms of just attach rates of the various subscriptions and then renewal rates?
And then I just have one follow-up to that.
Steffan Tomlinson - CFO
Sure.
So, deferred revenue grew very nicely.
It grew faster than our revenues on both a quarter-over-quarter and year-over-year basis.
When you think about the profile of the deferred revenue, it's split between subscriptions and maintenance.
The attach rates have basically held steady to directionally improved a little bit.
We have, in the subscription bucket, URL filtering, threat prevention, global protect, and now we've just started to monetize WildFire.
That wasn't in these latest results, but that will be a benefit for us going forward.
The attach rates haven't really changed that much since we talked last time, although we typically get, call it, 1 to 2 subscriptions at the time of the initial sale.
But as part of our land, expand and extend strategy, we are getting more subscriptions that are being sold into accounts after we land them.
On the maintenance front, the attach rates remain very high.
And in the renewals for both maintenance and subscriptions are also very high.
Phil Winslow - Analyst
Got it.
And just one quick follow-up on just pricing.
I mean, one of the concerns that investors have had is if there's a sort of a price war going on in the perimeter security market.
Just curious what you're seeing in terms of pricing this quarter versus last, and just sort of year-over-year?
And just any commentary around that would be great.
Mark McLaughlin - Chairman, President and CEO
Yes, hi, Phil.
Yes, we do see competition getting aggressive on pricing.
We've seen that for quite some time.
The -- there's been not a lot of impact to us on that because of a number of things.
And first and most importantly is the customers see the difference.
So, it doesn't matter how cheaply you want to sell your technology if it doesn't actually solve the problem they're trying to solve -- which, in this case is, can I safely enable an application?
And since we're the only guys in the market who have that technology, people continue to buy and they continue to pay a premium price for that.
I think you can see that reflected as well as our margins are very good; they continue to hold steady.
So we do see pricing pressure out there, but I don't see that being a successful tactic against us.
Phil Winslow - Analyst
Great.
Thanks, guys.
I'm glad to see that reacceleration next quarter.
Operator
Joel Fishbein, Lazard.
Joel Fishbein - Analyst
You guys, it looks like your spending on sales and marketing almost doubled year-over-year.
Can you just talk about ways in which you're focused on increasing distribution and maybe going after different vertical markets there?
That would be helpful.
Steffan Tomlinson - CFO
Sales and marketing is definitely a area where we're going to continue to make meaningful investments in.
What's been happening over the last year is, we have, again, a high-touch indirect fulfillment model where we have quota-carrying sales people.
And we are basically selling everything we can get in front of.
We're balancing that with a robust channel strategy, where we have a two-tier distribution system.
So we've been selectively adding high-quality partners to help extend our feet on the street without incurring too much cost.
Now you can see on a sequential basis actually sales and marketing as a percentage of revenue showed some nice leverage, you know, coming down -- call it about 200 basis points.
And that's something where our target model is 30% to 33% for sales and marketing.
And we feel like with the combination of our high-touch folks with a robust channel strategy, and the additional partnerships that we've announced with Citrix and VMware, et cetera, we should be getting more leverage out of sales and marketing going forward.
Joel Fishbein - Analyst
Great, thanks.
Operator
Jayson Noland, Robert Baird.
Jayson Noland - Analyst
Getting a lot of questions on software defined networking, and we saw the Big Switch Networks' announcement.
I guess how important is SDN to you and how are you positioned?
Mark McLaughlin - Chairman, President and CEO
Yes.
So I think SDN is a trend that lots of folks are talking about now.
And from our perspective, it's a good thing if it actually takes hold -- just because it makes what we're selling even more unique and relevant, and makes proprietary hardware guys less relevant.
But I'll let -- Nir is with us here too; I'll let him dive in on that for just a second.
Nir Zuk - Founder and CTO
Yes.
You know if you look at SDN, SDN is really looking at solving one big problem, which is very frequent changes in virtual data centers, where things move around.
And when virtual machines move around, or when they're added or removed from the infrastructure, security and networking has to follow them.
And that's really what SDN is trying to solve.
If you dig into the announcements that we've made around virtualization, a few weeks ago at Ignite, as part of PAN-OS version 5.0, you will see that there is not just that we announced a virtual firewall, the VM-Series, but we also announced functionality that can track the movement of virtual machines and data center, track their addition, their removal, their movement from one place to another.
And by that, by integrating that into your VM infrastructure into your orchestration tools, we are able to effectively perform what SDN performs, which is track changes in their data center and adjust to them in real-time without needing to change any configuration manually.
I think part of our work with VMware is also around that.
Jayson Noland - Analyst
Thank you.
Operator
Michael Turits, Raymond James.
Michael Turits - Analyst
Two questions.
One, was there any change in the mix of the amount of license that isn't deferred?
I don't know if that had any impact on product or licenses, as that was a little -- quite a little bit slower than the rest of the business.
Steffan Tomlinson - CFO
Yes.
There was really no change in mix in deferred revenue.
As we said previously, the vast majority is services and deferred revenue.
So that there was not any mix change.
Michael Turits - Analyst
Okay.
And then did you -- where did you end in terms of headcount?
What was the net add in terms of headcount this quarter?
What do you expect that to be like over the next couple of quarters?
Steffan Tomlinson - CFO
Yes.
So we ended at 847 total headcount in Q1 '13, and that was off of a Q4 '12 number of 755.
And what we stated previously was we anticipate adding approximately 75 to 100 heads per quarter.
The prior quarter, we came in at the lower end of that range.
This quarter, we came in near the high end of that range.
There's going to be some fluctuations as we go forward, but we are heavily investing in the business, but doing it in a profitable manner.
Michael Turits - Analyst
And if I could squeeze one more in, what about your expectations around CapEx?
I know that you've planned some accelerations there.
What's the schedule for that?
Steffan Tomlinson - CFO
The CapEx this quarter was approximately $4 million.
And for the rest of the year, we'll be in the, call it, low to mid-single digits.
We're not providing specific guidance on a quarterly basis, but expect to be in the low to mid-single digits in terms of CapEx.
Michael Turits - Analyst
Great, Steffan.
Thanks very much.
Steffan Tomlinson - CFO
Thank you.
Operator
Tal Liani, Bank of America Merrill Lynch.
Tal Liani - Analyst
My question is about the gross margin, and break it down between services and products.
If I compare your gross margin to some of your competitors, your margins are lower.
But earlier in their lifecycle, they also had similar gross margin, if I compare it to Fortinet, for example.
And later on in life, they had a massive boost in gross margin to the 80s and high 80s.
So the question is, is there something different in your business model that is going to result in lower potential upside to gross margin?
Is gross margin, mostly the services side, is it the function of volume?
How do we compare between you and other companies in the space on this number?
Thanks.
Steffan Tomlinson - CFO
Well, let's start with our target model, which is 70% to 73%.
We've been operating within that range.
When you make a comparison between Palo Alto Networks and some of the other folks out there, whether or not it's Fortinet or Checkpoint or Cisco in the security business, every company is slightly different.
What we've said to folks over time is, once we get to our target model, which is -- you know, when we talk about target model, we also look at operating margin, which is 22% to 25% -- we will reevaluate where we are in gross margin.
So this isn't a long-term target.
This is a target model that will be reassessed structurally.
A tailwind for gross margin will be increasing subscription sales.
And as a positive potential tailwind down the road is, we just introduced the paid-for version of WildFire, which will be additive, and it's very high gross margins for us.
You know, the maintenance part of our services revenue is very much in line with other companies of similar size and scale.
But unlike other companies that we compete with who are adding over 1000 customers per quarter, we're growing -- if you look at the Checkpoint's, the Cisco's and the Fortinet's, if you just compare numbers on a sequential basis -- we're growing 10 to 12 times faster against some of those folks there.
So we're making the investments in the maintenance organization to ensure that we have the best customer service that's out there.
So, to net it off, we think that, long-term, there could be some upside to the gross margin target, but we want to get to our target model first, then we'll reassess.
Tal Liani - Analyst
Excellent, thank you.
Operator
Jeff Kvaal, Barclays.
Jeff Kvaal - Analyst
I have two questions.
Mark, maybe this is one for you or Nir.
That is, could you help us understand the ADC vendors' role in all this?
I think many of them have started to talk a lot more aggressively about security in the past several quarters.
And then, Steffan, one for you as well.
Is there a seasonality element to the deferred revenue?
And with you -- affiliated with your fiscal year-end, should we expect a different pattern in the upcoming quarter?
Thank you.
Mark McLaughlin - Chairman, President and CEO
Hi, Jeff.
Yes, I'll take the first one on the ADC side.
I think specifically, you're probably talking about F5, as talks more and more security as a growth opportunity for them.
When they were doing that, they were talking about a different space than we are in from a security perspective.
So, they are sitting in a different part of the network for different purposes.
And from a network security perspective, they primarily continue to talk about stateful inspection firewalls at different points in the data center market we do not play in today.
So, I'll let (multiple speakers) Nir --.
Nir Zuk - Founder and CTO
Yes, I can give you some more details around that.
If you look at where customers deploy security, there are several places.
First is, of course, the perimeter.
The Internet facing -- what's called the Internet facing firewall.
And really the requirements there are next-generation firewall, meaning safely enabling applications, scanning traffic for viruses, for spyware, for all kinds of malware, for exploits, for data leakage and so on.
And, of course, we don't see F5 playing in that market at all.
We don't see stateful inspection as a viable solution in that market at all.
The second area where security is deployed is in the data center.
And even there, there are two use cases.
The first use case is the external data center -- the Internet-facing data center, where you're on your Web servers.
And the requirements there in many cases from a security perspective are pretty minimal, meaning allow only traffic to the Web servers, meaning to ports 80 and 443, and then blocking all the rest of the traffic.
That, of course, can be achieved using a simple stateful inspection firewall, and I think that's what the ADC vendors such as F5 are doing.
They call it an outbound firewall.
The third area where you see security being deployed, which is still in the data center, is in the corporate data center.
In the corporate data center, the requirements are again for next-generation firewalls, because customers want to control access to applications -- control who can access which applications, perform which functions in these applications, and also scan the data for bad things and for good things moving around.
That's, again, something that we don't see the ADC vendors playing in, and we're not sure whether they have a path of getting there without significant investment in anti-malware technology, in IPS technology, data leakage technology, as well as next-generation firewall technology.
In terms of market size, we think that the external firewall -- external Internet-facing data center firewall is a much smaller market than the corporate data center and the Internet-facing firewall, the perimeter firewall.
And these are the areas we focus at.
We believe the ADC market, the ADC vendors are focusing on the small part of the market, which is the Internet-facing security or Internet-facing firewall.
Mark McLaughlin - Chairman, President and CEO
And Jeff, on the second question, is there a seasonality element to deferred revenues?
I would say that it's still too soon to call seasonality trends, although we're seeing a little bit of natural fiscal year seasonality with Q4.
We were happy that -- and pleased with our sequential growth on a revenue basis and on the deferred revs.
With our guidance, we're obviously guiding up sequentially, and you would expect that there would be also an increase in deferred revs.
We're not going to get into the specifics around what the rate of growth and deferred revenues is forecasted to be, but we anticipate that that balance should grow.
Jeff Kvaal - Analyst
Thank you very much.
Operator
Walter Pritchard, Citigroup.
Walter Pritchard - Analyst
Mark, I'm wondering if you could talk about -- you've had, I think, Mark Anderson, the new Head of Sales on board here for now a full quarter.
I'm wondering if you could talk about what changes have been made or you foresee making under his leadership in running sales?
Mark McLaughlin - Chairman, President and CEO
Yes.
Thanks, Walter.
Yes, Mark is doing a fantastic job, not surprisingly, for us, given all the demonstrated success he's had at F5 in building a business, growing these kind of rates over time at scale.
A number of things that you're doing that are probably relevant, the first is, is that we're very, very focused on large accounts.
So, the Company has always been successful in the selling, and I'll call the Global 2000.
And you can see from our LTV numbers that we continue to add business in all the accounts, but particularly in the large accounts as well.
We just really hadn't been super organized about that, and Mark's done a lot of work on bringing a lot of organization and focus into larger accounts, so we can keep the LTV growing there as well as across the entire customer base.
In addition to that, making sure that we're doing as good a job as we can with the channel in a coordinated fashion.
We didn't really have an owner across the Company from a channel perspective before.
Mark has really taken the reins on that as well, with some new hires in the organization working with the channel folks.
And then the third is just a lot of operational discipline that he's brought to the system as well, from certainty of numbers, commit culture, those kind of things which are very important, obviously, when you're running a publicly-traded company.
So, all very, very positive things going on here.
Walter Pritchard - Analyst
And then I'm not sure for Mark or for Steffan, but you mentioned the LTV number and the 9.9 versus the 9.5.
Can you talk about how much of that you're seeing come in from layering in annuity and WildFire being the most recent, versus just simply going in and more fully penetrating a customer that starts out with you guys in one part of the network?
Mark McLaughlin - Chairman, President and CEO
It's a mix in a good way, a good blend.
So in the cases where the customers are doing repeat purchases -- and these are pretty much across the board of all the customers doing these repeat purchases -- we fine-tune things that happen.
And they are a good blend of their buying more devices as they continue to spread those out in the network.
And they continue to buy more services to put on those devices.
I think an interesting thing there, Walter, is, what's penetration even in some of our largest customers.
And our conversations have been -- looks at their networks, how large the networks are, boxes that have been deployed over time.
We think that's so -- even some of our largest customers relatively small, just kind of penetration, because these guys measure devices in hundreds and sometimes thousands of devices in some of these biggest networks.
Walter Pritchard - Analyst
Got it, great.
Thanks for taking the questions.

Mark, I know we're only about three weeks removed from the Ignite User Conference, but just wondering even anecdotally (technical difficulty) --
Mark McLaughlin - Chairman, President and CEO
Gregg?
Operator?
Operator?
Steffan Tomlinson - CFO
Do we need to, like, get another phone line up?
Mark McLaughlin - Chairman, President and CEO
(multiple speakers) Hey, everybody, this is Mark.
I understand there's some issues where folks can hear us but we can't hear anything on the line, so -- (multiple speakers)
Operator
(multiple speakers) But this is the -- yes, I'm back on the line, sir.
It looks -- I do apologize.
All our lines had just dropped, so we can just proceed with our next question.
It'd just be one moment.
Our next question comes from the line of Gregg Moskowitz, Cowen.
Mark McLaughlin - Chairman, President and CEO
Hey, Gregg, are you back?
Gregg Moskowitz - Analyst
I'm back.
Can you guys hear me?
Mark McLaughlin - Chairman, President and CEO
Yes, we are.
Sorry about that.
Not sure what happened.
Gregg Moskowitz - Analyst
Okay.
Second time's the charm.
Hi, guys.
So, Mark, I know we're only about three weeks removed from the Ignite User Conference, but just wondering, even anecdotally, what the early interest has been like thus far for your PA-3000 appliances?
Mark McLaughlin - Chairman, President and CEO
It's good, Gregg.
So if I could just take that at a higher level and I'll talk 3000 specifically for a second.
But the User Conference, Gregg, we had was our very first one.
We had almost 1000 folks there.
And I thought it was very interesting that almost all of them paid to attend, which is unusual in these tough times.
But great, great feedback from folks across the board about things we've done, and very excited about the things that we launched.
So we put a lot of stuff in the market here recently and spent a lot of time with the customers explaining it.
The 3000, in particular, is a device that was clearly being asked for from the market.
There's a clear market need for that, for a midrange device.
And we've been selling it ever since the day we announced it.
Gregg Moskowitz - Analyst
Okay, great.
And then just a quick follow-up for Steffan.
The tax rate, as you noted, was higher this quarter, and I understand there are going to be fluctuations going forward.
Just wanted to get a sense for fiscal '13.
Are you still expecting the tax rate to be 34% to 39%?
Steffan Tomlinson - CFO
You know, right now, I think it's going to be at the higher end of that range.
After we get through this fiscal quarter Q2, we'll give a little bit more guidance on the back half -- for the back half of the year on the next call.
Gregg Moskowitz - Analyst
Okay, great.
Thank you very much.

Just as it relates to some of the value-added subscriptions that you can cross-sell to clients, can you just give us, like, bring us up to speed on where you're at?
And maybe talk a little bit about the economic model in terms of what you're seeing from customers?
Mark McLaughlin - Chairman, President and CEO
Sure.
You mean on subscription services.
So now with the paid version of WildFire now on the market, we have four subscription services.
We have threat prevention, we have URL Web filtering; we have our GlobalProtect, and now the paid-for version of WildFire.
The economics are similar for the subscription services, so it's 20% of the list price of the device per subscription service.
So, there's been no change to that since the last time we talked.
Brent Thill - Analyst
Okay, great.
And maybe for Nir, just as it relates to everyone's talking about APT, and they're looking at potential incrementally priced products to go after this.
Are you thinking of this as an incrementally priced piece?
Or is this embedded in the platform?
Nir Zuk - Founder and CTO
So the way -- so our APT or modern malware service called WildFire is made of two pieces.
The first piece is a collection service where we collect -- we let our customers run their traffic through a separate -- through a cloud-based service, which we don't charge for.
And we scan their traffic and we look for malware in it.
And if we find malware, we take that malware and we generate immediately signatures to go and block that malware and similar malware trying to get on the customer network, as well as to block existing instances of that malware that are already on the customer network trying to communicate back with the bad guys.
Receiving those signatures is a paid-for service.
So, sending us traffic for examination is a free service.
And this is really what our competitors are selling.
Meaning, if you look at the standalone APT vendors, what they are selling is a detection service.
They don't have the prevention -- they don't have prevention capabilities, mostly for the fact that they don't have a high-speed firewall IPS and anti-malware device sitting in the network.
They don't provide that and nobody is looking at them to provide that.
So we decided to give that part to the customer for free, because we also see value from collecting those samples.
The second part that we do, which is unique to Palo Alto Networks -- no one else in the market can do that -- is to turn those signatures around -- excuse me -- turn this malware around into signatures, that, as I said, are designed to block both the malware trying to get in the network, as well as existing instances of the malware trying to get out of the network.
This is unique to Palo Alto.
And this is what we charge for as part of the new WildFire subscription service.
Brent Thill - Analyst
Great.
Thanks for clarifying.
Operator
(Operator Instructions) Frederick Grieb, Nomura.
Frederick Grieb - Analyst
Two from me.
First, some public software companies disclosed how changes in billing terms may have impacted year-over-year billings growth in the quarter.
Could you give us a similar commentary?
And the second question is just on the competitive environment.
You're clearly taking share, but when you compete against Checkpoint, Cisco, Juniper, who do you have the best win rate against and why?
Steffan Tomlinson - CFO
On the first one, we have a hybrid revenue model.
And one element of that revenue model is SaaS-based.
We are -- the crown jewels of the Company are in software, but we are an appliance-based vendor that has a portion of the revenue stream being SaaS.
So with that as the backdrop, there's no changes in billing terms for our services or our subscriptions or our maintenance.
So there's no impact on a quarter-over-quarter basis relative to billings.
Now I will say that billings is not something that we focus on, because we're primarily a book and ship business.
With that said, billings was $110 million in the quarter and it grew faster than revenue.
Mark McLaughlin - Chairman, President and CEO
And yes, Frederick, on your competition question, those are the three firewall vendors you see in the market mentioned -- Cisco, Juniper, and Checkpoint, and we have been taking share from all three of those vendors.
As far as which one we see more often, Cisco has the largest market share, so we tend to see them in more instances.
You remember, most of the sales we do are displacement sales.
So they were in more accounts already to start with, so we tend to see them more often as far as who we're displacing.
But it generally just follows the market share where folks are already installed.
Frederick Grieb - Analyst
I guess I was wondering more, I guess, win rate, do you beat Cisco 60% of the time?
Checkpoint 70% of the time?
Do you have a statistic like that?
Mark McLaughlin - Chairman, President and CEO
Yes, I think the better way to look at that is, the way we look at it is, when we get into an account, like we said earlier, if we can get the technical evaluations on our win rates are very high, and that is across the board against any competitor.
It doesn't matter who it is.
Frederick Grieb - Analyst
Great.
Thanks a lot.
Operator
Jonathan Ho, William Blair.
Jonathan Ho - Analyst
Just one question around the competitive environment.
Are you seeing any competitive response or any shift there in terms of maybe a reaction from some of the incumbents that are losing significant share, either on the pricing front or on the product side?
Mark McLaughlin - Chairman, President and CEO
Hey, Jonathan.
As I said a little earlier -- I'll take those in reverse on the pricing side.
We've seen some more aggressive pricing in the market, which is a natural response if you don't have the technology that the customer is after, which is the more important piece.
We haven't seen any competitive response to what we're doing as far as safely enabling applications.
So, interestingly as well, we pay attention to that question a lot.
We think we're very far ahead of the competition already.
We think we've widened that gap with the five products we put in the market in the last few weeks.
And when we asked our close-to-1000 customers that came to our User Conference what they thought about that, just resoundingly, they were very clear that we're unique in the market.
Jonathan Ho - Analyst
Got it, got it.
And can you guys talk a little bit about channel incentives in training?
And maybe some of the results of the investments that you guys have made on that side, and potentially what the impact could be sort of going forward?
Mark McLaughlin - Chairman, President and CEO
Yes, so on the channel side, we have a bit of a different model than other folks.
So we're a quality versus quantity shop.
We have about 850 channel partners today.
That -- we've grown that.
That will continue to grow over time at a pace we like.
The reason I mean a pace we like is, it's very important when you have the disruptive technology in the market, and you're almost always displacing an existing provider, that you're adequately trained to represent the technology in order to get the sale done.
So we're very careful with who we bring on from a channel perspective.
And then we spend quite a bit of time with them.
And this does cost money and resources to get them educated and trained, and tested and certified.
But, the results speak for themselves; when they go through all that with us, they do very well.
We had our North American Partner Conference right after our User Conference actually, and it was very interesting -- we had over 200 of our partners there.
Just asked the quick question of how many folks had more than doubled their business with Palo Alto Networks in the last years from the last conference, and we had multiple dozens of people stand up in the room.
And everybody else in the room said, yes, I'd like to do that too, right?
So that continues on the entry side.
Also, at the User Conference I'll note we trained a couple hundred -- we certified a couple hundred of our partners and users as -- through testing, which is important as well, as making sure they understand the products.
So I think that's all working really well for us and at the pace that we like it.
Jonathan Ho - Analyst
Got it, thank you.
Operator
Catharine Trebnick, Northland Securities.
Catharine Trebnick - Analyst
Could you provide -- at the beginning of the call, you had said that you were up significantly 14% quarter-over-quarter.
But could you delve into some of the vertical segments that are possibly driving some of this?
And if those are driven by any of compliance or regulatory in nature?
Thanks.
Steffan Tomlinson - CFO
Yes, Catharine.
So, if we look -- if we break down our entire business from a vertical perspective, it's very nicely distributed -- not only vertically but geographically as well -- it's very nicely distributed.
So we don't have a -- an overwhelming concentration in any vertical, which we think gives a good degree of lower risk in the business.
No vertical accounts for more than 15% of our business today.
And the ones that tend to be higher, you know, it's closer to the 15%, are financial services, the public sector space, and the high technology space -- you know, not surprisingly, since they have a lot of assets online to protect.
Catharine Trebnick - Analyst
How about healthcare?
I'm kind of curious on that, since there's a lot of move to digitization of all the patient records.
It seems like that might be an emerging opportunity.
Mark McLaughlin - Chairman, President and CEO
Yes.
No, that's very prescient.
So, I think healthcare is probably number four or five.
I listed the first three, but you picked up on -- it was either the next one or one right below it.
But, yes, I think what you're getting at is, is that in a number of industries, they have different compliance requirements and regulatory requirements in other industries.
And if you -- if that's the world you live in, then you are likely to be very interested in our technology.
And healthcare is clearly one of those.
Catharine Trebnick - Analyst
All right.
Thanks.
