About the Company

Cylake

AI-powered on-prem security platform for government

Cylake builds an AI-native security platform designed for government agencies and highly regulated enterprises that cannot use public cloud. It provides on-premises and private-cloud appliances that collect enterprise data into a single data lake to support detection, investigation, and AI-powered workflows without phoning home. The platform is operated entirely within customers’ environments, using local data storage and processing to maintain control and compliance. Cylake differentiates itself through deep government/regulated focus, a leadership team with experience from Palo Alto Networks and SentinelOne, and a cloud-free approach that keeps data and analytics inside customer premises. The company aims to reach beta in late 2026 and general availability in 2027, backed by significant venture funding to develop the platform and expand the team.
