Palo Alto Networks founder Nir Zuk unveiled his latest endeavor: an “AI-native” cybersecurity platform.

Dubbed Cylake, Zuk’s new project looks to replace hard-to-integrate on-premises or private cloud security products for large enterprises with visibility across their entire technical stack.

Full details on what Cylake actually does at this stage are fairly scarce, but the startup’s website states it “combines hardware and software components to provide an end-to-end cybersecurity system.”

“We are developing a complete, AI-native, data-driven cybersecurity platform built on a single data foundation, ensuring operational sovereignty for our customers,” Cylake’s website reads.

Zuk left Palo Alto Networks last August after founding the firm back in 2005. The company would go on to become a behemoth in the cybersecurity space, providing services to the vast majority of the Fortune 100 and routinely reinventing and augmenting its services through myriad acquisitions.

That constant reinforcement culminated in the $25 billion mega-deal for CyberArk, with the vendor turning its attention to shoring up all things agentic, given the ever-growing number of AI agents being deployed by clients.

Zuk’s newest venture also looks to counter the growing security threats related to AI, with Cylake using AI tools and tricks in a bid to counter AI-led attacks, arguing that existing security options are “insufficient and create exploitable vulnerabilities.”

But the Palo Alto founder isn’t alone at Cylake, as he’s joined by some other cybersecurity bigwigs.

Also on board is Ehud (Udi) Shamir, who co-founded SentinelOne, the Israeli cybersecurity firm Zuk’s prior employers were reportedly interested in buying. Shamir left SentinelOne in 2018, did a stint as senior security researcher at Apple, and then went on to found cybersecurity startup ThreatOptix in 2020. Shamir also spent a little over a year at Palo Alto Networks as a distinguished software developer and security researcher.

Rounding out the Cylake trio is Wilson Xu, who spent more than a decade at Palo Alto as its EVP of engineering, with stints at Juniper Networks and NetScreen Technologies (prior to it being acquired by Juniper) under his belt.

The trio is backed by Greylock, the venture capital giant that invested in Zuk when he was creating Palo Alto Networks.

“We are excited to partner with the Cylake team to build an AI-driven, secure future for customers with data sovereignty requirements," Greylock partner Asheem Chandna wrote.
