Ex-Microsoft Security Copilot builders just raised $100M because your EDR can't see what AI agents are doing

Your endpoint security was built to catch malware.

Ent just proved that's irrelevant.

The RiskIQ co-founders who built Microsoft Security Copilot just emerged from stealth with a $100M seed round — the largest in cybersecurity history.

Their thesis: the threat is no longer suspicious software. It's authorized humans and AI agents doing things they shouldn't, in ways your EDR was never designed to see.

Here's what they understood that CrowdStrike missed.

Traditional endpoint detection looks for malware signatures and anomalous processes. But AI agents operate with legitimate credentials, inside approved applications, following natural language instructions.

There is no malware signature when an AI agent exfiltrates data through a Slack message it was authorized to send.

Ent runs AI reasoning directly on the endpoint device. It evaluates the intent behind every action — human or agent — before it executes. Not after. Before.

Already deployed across Global 2000 companies in financial services, defense, and hospitality.

The investors decoded the shift instantly.

Decibel led. Sequoia, In-Q-Tel, and Crosspoint Capital Partners followed. In-Q-Tel doesn't invest in nice-to-have security tools. They invest when the intelligence community has a problem that existing vendors can't solve.

Your CISO's security stack was built for a world where humans were the primary threat actor. That world ended eighteen months ago.

Audit your endpoint security coverage for AI agent activity today. If your EDR vendor can't explain how it handles authorized-but-malicious agent behavior, you have a gap that Ent just proved is worth $100M to close.

SIGNAL: The largest seed round in cybersecurity history signals that enterprise security architecture is fundamentally broken for the AI agent era. Your EDR vendor's roadmap just became your biggest risk.
