Ent is a workspace security platform built around real-time prevention rather than after-the-fact detection. A lightweight on-device agent for Windows, macOS, and Linux, paired with a browser extension, uses computer vision and small specialized AI models to read the intent behind actions taken by both human users and AI agents across apps, browsers, and local workflows — then applies customer-defined policy through just-in-time interventions before a risky action completes.
The company emerged from stealth in June 2026 with $100 million in seed funding led by Decibel Partners, with participation from Sequoia, Crosspoint Capital, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel. Ent’s platform is already generally available and deployed with Global 2000 customers in hospitality, financial services, and defense for use cases including insider risk detection, AI governance, data loss prevention, and incident investigation. Ent is based in San Francisco.
