Cylake AI-Native Sovereign Security Platform

Cylake is a cybersecurity company headquartered in Sunnyvale, California, founded in 2026 by Nir Zuk (founder of Palo Alto Networks), Udi Shamir and Wilson Xu. It targets large and regulated organizations that need advanced protection but cannot rely on products tied to the public cloud.

The platform is an AI-native, on-premises system delivered as rack appliances that scale by adding units. A single ingestion pipeline feeds one data lake for long-term retention, investigation on hot storage and on-board AI compute that explains findings in plain language, working in fully air-gapped environments.

• Single ingestion pipeline: one lake collects all security data.
• Consolidated functions: several cybersecurity functions run in one platform.
• Long-term retention: enterprise data is kept near real time.
• Hot-storage investigation: analysts query recent data quickly.
• On-board AI: built-in compute explains findings in plain language.
• Air-gapped sovereignty: runs fully on-premises or in private cloud.

Data sovereignty and regulation push governments, banks and critical infrastructure operators to keep security telemetry in-house, away from public cloud. Southeast Asian regulators increasingly require local data residency, which favors on-premises security platforms.
