Transcript of Employee Call

The following transcript contains excerpts from the PANW Chief Executive Officer’s discussion with the CyberArk Chief Executive Officer at the CyberArk all-hands employee call on July 30, 2025.

[Excerpt]

Nikesh Arora: If our teams are to trying to build an evergreen cybersecurity company because don’t forget how many cybersecurity companies go through a wave, and over time vanish. We both are trying to build businesses that are built to last. We both believe that, providing a comprehensive solution end to end to the customer makes the most sense, because that’s the easiest path to being their partner.

[Excerpt]

Nikesh Arora: And I think both of us believe that with AI there’s a huge inflection point and scale matters. And like, you know, you guys have great scale in the identity space. We have scale in network security. We have scale and security operations, and we need to embrace your learnings from identity and do it together.

At Palo Alto we have made 24 acquisitions, and I’ll never use the word acquisitions because we’ve partnered with 24 teams, and principally what we do in that philosophy is that because that team has proven themselves in a category. We don’t play in. They come, run that space with us.

So at Palo Alto the leaders of identity are going to be the leaders from CyberArk. Because you guys know how that space works. You guys have built it. We will rely on you for your expertise, your knowledge and your leadership to work with us to win with the customer together.

[Excerpt]

Nikesh Arora: We’re gonna run CyberArk as our Palo Alto’s identity solution for our customers.

And the good news is there is no overlap from a technological perspective. Pretty much everything you do is something we don’t do. Maybe there’s a liberal or open cloud identity. But that’s easy to solve within your platform, and I think the real value is, how do we run our 3 or 4 platforms independently? And how do we create a common layer amongst all of them? And we have a solution for that is run through our XSIAM platform, which is non-overlapping. So look, I think there’s a huge opportunity collectively between the CyberArk team, the Palo Alto team.

[Excerpt]

Nikesh Arora: My success, our success is only possible with your success.

So I just want to tell all of you that you know. Rest assured we are good people. Everybody at Palo Alto you’ll experience is going to treat you like part of the family. There’s no us and them. There is no acquirer and acquisition there is. We’re now working for the same company in the future. When I get it done we’ll be working together. We have a similar objective, and you know intelligence has no boundaries. There are equally smart people at both sides. We just have to be conscious, we have to collaborate. We have to listen, and because of non-overlapping nature, I don’t see that there’s going to be huge.

[Excerpt]

Nikesh Arora: Because the one thing I’ve learned in the last 7 years, the one constant in cybersecurity is change, because our job. Both yours and ours is to protect against the next emerging technology, which means we have to be adaptable to change.
