Security Startups

Ent

Ent builds an intent-aware workspace security platform whose lightweight endpoint agent judges what users and AI agents are doing and stops risky actions before they become incidents.

Proof of life. Emerged from stealth with a $100M seed round led by Decibel, June 2026

About Ent

Ent places a lightweight agent on Windows, macOS and Linux devices, plus a browser extension, that runs small AI models locally.

The models build a record of work activity, infer the intent behind actions and apply customer policies at the moment of action.

When a policy is hit, the agent can intervene just in time, for example to stop data loss, flag insider risk or govern how staff use AI tools. It also helps reconstruct events after an incident.

Ent is designed to work alongside existing EDR, SIEM, SOAR and IAM tools, and can be hosted by Ent or in the customer's own cloud. The company is based in San Francisco.
