- Horizon3 raised a $250 million Series E at a $2 billion valuation, more than tripling its previous valuation according to TechCrunch's Kate Park.
- NodeZero, Horizon3's AI penetration testing platform, autonomously finds and exploits attack paths in production systems — going beyond passive scanning to actively simulate attacker behavior.
Why it matters: The more-than-tripled jump to a $2 billion valuation signals that investors are pricing AI-native offensive security at a premium, with the $250M round sized to scale NodeZero's automated exploitation capabilities as AI-generated threats escalate.
