The company raised $45 million in a Seed round led by [Greylock](https://www.trendhunter.com/trends/xbow-ai-agents) 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](https://www.trendhunter.com/trends/ai-processing), reflecting a broader trend toward cloud-agnostic, sovereignty-minded enterprise security.
