RiskIQ/Security Copilot Founders Exit Stealth With $100M for 'Intent-Aware' Agent Security (Ent)

SiliconANGLE·medium signal

Ent Security emerged on June 16 with a $100M seed (led by Decibel, with Sequoia, Craft, Felicis, and In-Q-Tel) founded by Elias Manousos and Brandon Dixon, the RiskIQ duo behind Microsoft Security Copilot. Its lightweight endpoint agent (Windows/macOS/Linux + browser extension) inspects whether the intent behind a user or AI agent's action matches company policy before the action completes — moving from reactive detection to preventive control, already running in Global 2000 firms. The signal for builders: 'read the intent of the agent' is emerging as the post-prompt-injection security primitive, and it is now venture-funded at scale.
