Cylake is a new cybersecurity startup founded by Nir Zuk, Wilson Xu and Ehud Shamir, presenting an AI-driven security platform designed to run without public cloud dependency, featuring a data-first architecture that preserves operational sovereignty. The company raised $45 million in a Seed round led by Greylock to build a unified, visibility-focused system that aggregates telemetry across infrastructure layers. Cylake’s design emphasizes on-premises and private-cloud deployment, collaborative development with select design partners and AI-native analytics to reduce fragmented toolchains and blind spots.
For regulated institutions and organizations bound by national security or compliance limits, Cylake aims to deliver advanced AI protections while keeping sensitive data fully controlled, reflecting a broader trend toward cloud-agnostic, sovereignty-minded enterprise security.

What Makes This Trend Stand Out
- AI-first On-premises Security
- Local AI models that perform real-time threat detection on-premises, reducing reliance on public cloud inference and minimizing data exposure.
- Data Sovereignty-first Architectures
- Architecture centered on keeping telemetry and models within institutional boundaries, preserving compliance and enabling tailored threat intelligence.
- Unified Telemetry Visibility
- Consolidated cross-layer telemetry that removes fragmented toolchains and surfaces correlated incidents for more contextualized AI analysis.
Sectors Adopting This
- Financial Services
- Highly regulated institutions that require custody of sensitive data and could leverage on-prem AI to maintain compliance while improving fraud and intrusion detection.
- Government and Defense
- National security environments that demand cloud-agnostic deployments and specialized AI analytics to monitor complex infrastructure without external dependencies.
- Healthcare
- Clinical and research organizations where patient-data privacy and regulatory constraints drive adoption of private-cloud or on-prem AI security to protect health records and medical devices.
