Ent.AI raised $100 million in a round led by Decibel Partners to scale its AI-native endpoint security platform. The company applies AI to detect and respond to threats at the device level, pitching autonomous defense as the necessary answer to a wave of increasingly automated and AI-assisted attacks.
The round lands amid a surge in security spending and funding. As attackers adopt AI to generate malware, automate intrusions, and scale social engineering, defenders are turning to AI-native tooling that can match that speed -- and investors are funding the shift aggressively. Cybersecurity has remained one of the most consistently fundable categories through every recent market cycle.

For builders, Ent.AI underscores that the security market rewards companies built AI-first rather than bolting AI onto legacy products. The threat landscape is now an AI-versus-AI contest, and the buyers with the most to lose are moving budget quickly toward defenses designed for that reality.
