Ent, founded in 2025 and based in San Francisco, offers an intent-aware workspace security platform that helps organizations understand and intervene in risky actions by humans and AI agents before they escalate into incidents, built on the premise that AI compresses the compromise-to-impact timeline. It focuses on understanding intent rather than matching known-bad signatures.
It was founded by RiskIQ co-founders and members of Microsoft’s Security Copilot team and raised one of the largest seed rounds in cybersecurity history.
Innovation Matrix Assessment
Built an intent-aware workspace security platform from a May 2025 founding to a fully articulated product at stealth exit just over a year later.
Very small team (12 employees) at launch despite the enormous raise; operational scale is not yet proven.
Emerged from stealth with a $100M seed round in June 2026 led by Decibel with Sequoia, Crosspoint Capital, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel participating.
Intent-aware prevention (rather than signature matching) targeting the compressed AI compromise-to-impact window is a differentiated conceptual approach.
Too early for independent efficacy data; the founding team's RiskIQ pedigree lends credibility but is not efficacy evidence itself.
Intervening in risky human and AI-agent actions before they become incidents addresses a rapidly intensifying, durable enterprise risk.
Why CISOs Should Care
Ent gives CISOs an intent-aware workspace security platform that helps organizations understand and intervene in risky actions by humans and AI agents before they escalate into incidents, built on the premise that AI compresses the compromise-to-impact timeline.
What Makes It Different
Ent focuses on 'intent-aware' prevention -- understanding what a user or agent is trying to do, not just matching known-bad signatures -- founded by RiskIQ co-founders and members of Microsoft's Security Copilot team.
The Matrix Verdict
48/100 — EMERGING / UNRANKED
One of the largest seed rounds in cybersecurity history, reflecting exceptional investor confidence in a veteran team's approach to intent-aware, AI-era endpoint/workspace prevention.
Editorial Note: Claims vs. Verified Findings
The characterization as 'one of the largest seed rounds in cybersecurity history' comes from press coverage, not an independently audited industry ranking.
