Cylake is building a complete, AI-native, data-driven cybersecurity platform for the world’s largest and most regulated institutions. Our approach does not depend on the public cloud; instead, it’s designed to operate on-premises or in private cloud environments, so that our customers retain full data and operational control.

Co-founded by Nir Zuk, Wilson Xu, and Ehud (Udi) Shamir, Cylake is led by a team of experienced security engineers and executives. Backed by our leading investor Greylock Partners, we are focused on helping organizations with strict regulatory and operational constraints to maintain security at scale.

Our platform is currently under development, in consultation with several design partners, and is planned for general availability in early 2027.


Our mission is to support organizations and enterprises that need sovereign, complete, and transparent agentic protection against cyberattacks.

Our vision is to bring cybersecurity back home for organizations that require complete sovereignty and to operate from a single data store, so that our customers can enjoy optimal security and governance under their full control.
