Nir Zuk, founder of Palo Alto Networks, has unveiled his new startup, Cylake, which has raised $45 million in a Seed funding round led by Greylock Partners. Zuk has joined forces with Wilson Xu, a longtime Palo Alto Networks engineering leader, and Ehud (Udi) Shamir, co-founder of SentinelOne.
Cylake is focused on building the industry’s leading AI-native cybersecurity for customers that require total data sovereignty.
The company was founded to address the challenges faced by the world’s largest and most regulated organizations and institutions, which demand state-of-the-art cybersecurity but are often unable to use products tied to the public cloud.
“Cybersecurity is constantly evolving, and sometimes new challenges demand completely new approaches,” said Nir Zuk, Founder and CEO of Cylake. “Cylake is for institutions where maintaining full control over data and operations is not optional.”
“The next generation of cybersecurity will be AI-native, agentic, and built on holistic data and context,” said Asheem Chandna, Partner at Greylock Partners. “Cylake is focused on a segment of the market where security must operate under full control to meet regulatory and operational reality.”
Cylake’s first products are anticipated to be on the market in early 2027.
