Neo Security bags $100M to build the secure control layer for enterprise AI agents

Agentic software control startup Neo Security Inc. said today it’s exiting a years-long spell in “stealth” mode after raising $100 million in funding.

The round was led by top tier venture capitalists in Andreessen Horowitz and Bessemer Venture Partners, and saw participation from Craft Ventures and Merlin Ventures. They’re betting that enterprises are going to need purpose-built security to safeguard their increasingly autonomous artificial intelligence systems, and likely need it soon.

Built by former executives and engineers from SentinelOne Inc., Wiz Inc. and Palo Alto Networks Inc., Neo aims to provide security operations teams with the inventory, posture intelligence, attribution and policy controls needed to manage and secure AI agents across entire organizations.

The growing adoption of autonomous AI agents that can conduct work unsupervised on behalf of humans is happening at such rapid speed that traditional security systems cannot keep pace, and it means that the attack surfaces of organizations are changing and expanding faster than ever. Enterprises are adding AI-native tools, but the bigger concern is that even the traditional software they use is integrating agentic capabilities.
