Ent Security

Ent Security is an intent-aware security platform for the AI-native enterprise. The company extends endpoint security into a real-time layer of prevention that covers both human and AI-driven work, analysing not only what users and AI agents do but why they do it. Its technical work spans real-time behavioural analysis, insider risk detection, AI usage governance, data loss prevention, threat prevention and incident investigation with behavioural context.

The Ent Platform reads human, AI and application activity in real time to detect insider risk, govern AI usage, prevent data loss, stop last-mile threats and investigate incidents with full behavioural context, allowing security teams to intervene at the moment of risk. The platform is in production with Global 2000 customers, across the hospitality, financial services and defence sectors.

The company was founded by Elias Manousos and Brandon Dixon, former co-founders of RiskIQ (acquired by Microsoft) and the team behind Microsoft Security Copilot. Ent Security has raised $100m in seed funding from investors including Decibel, Sequoia, Crosspoint Capital and In-Q-Tel. It is headquartered in San Francisco, California.
