Ent Security

Ent Security operates from San Francisco, California, building what it describes as an intent-aware security platform designed for the AI-native enterprise. The company's core technology extends endpoint security into a real-time prevention layer, analysing not only what users and AI agents do but the reasoning behind their actions. This approach enables security teams to intervene precisely at the moment of risk, covering insider threat detection, AI usage governance, data loss prevention, and last-mile threat prevention with full behavioural context.

The platform reads human, AI, and application activity simultaneously, positioning itself at the intersection of several critical technical domains: intent-aware security, real-time prevention, and behavioural context investigation. Ent Security's customers span the Global 2000, with deployments across industries including financial services, hospitality, and defence - sectors where the consequences of security failures are particularly severe.

The company secured $100 million in seed funding, a notable figure at that stage, signalling strong investor conviction in its approach to a rapidly evolving threat landscape shaped by the proliferation of AI agents alongside human operators.
