Cylake Tech Stack

On-premises AI-native cybersecurity platform for regulated enterprises

Computer and Network Security Sunnyvale, CA 11–50 employees Founded 2026 Privately Held

Cylake is pre-launch, building a cybersecurity platform designed for on-premises and private-cloud deployment—a deliberate constraint that reflects the regulatory and data-sovereignty requirements of their target market. The tech stack spans low-level systems work (Linux Kernel, SELinux, dm-verity, IPMI, PXE) alongside data infrastructure (Kafka, Spark, Flink, Iceberg, Neo4j), indicating a platform that must handle both endpoint hardening and large-scale telemetry processing. Hiring is senior-heavy (6 of 7 open roles at senior+ level) and concentrated in engineering and data, typical of early-stage infra companies building core primitives before go-to-market.

About Cylake

Cylake is a pre-release cybersecurity startup in Sunnyvale building a complete, AI-native platform for large regulated institutions such as banks, government agencies, and critical-infrastructure operators. The platform operates entirely on-premises or in private cloud environments, ensuring customers retain full control of security telemetry and operational data—a key differentiator for compliance-heavy verticals. Active development spans endpoint security agents, distributed system management, policy engines, and scalable data pipelines. General availability is planned for early 2027.
