Cylake: AI-Native Cybersecurity With Data Sovereignty

Cylake is an AI-native cybersecurity platform built for organizations that cannot send sensitive data to the public cloud. It applies AI-driven threat detection and response across a company's systems while keeping all data inside the customer's own on-prem or private-cloud environment — a combined hardware and software stack aimed at regulated industries where data sovereignty is non-negotiable.

By unifying signals into a single data foundation that stays in the customer's control, Cylake targets the gap between modern AI security and the strict data-residency requirements of regulated sectors.

Key Features

• AI-native threat detection and response
• Unified data foundation for full visibility
• On-prem or private-cloud deployment for data sovereignty
• Combined hardware and software stack
• Agentic protection
• Built for sensitive, regulated data

Ideal Use Case

Cylake fits banks, governments, healthcare, and other regulated organizations that want modern AI-driven security but are barred from public-cloud SaaS by data-residency rules. It suits security teams that need both AI capability and full control over where data lives.

How Cylake differentiates

Cylake delivers AI-native security entirely within the customer's environment, rather than as a cloud service, addressing data-sovereignty constraints head-on. It raised a $45M seed led by Greylock and was co-founded by Nir Zuk, founder of Palo Alto Networks, with Udi Shamir, a SentinelOne co-founder.
