Vanta is acquiring Pillar Security in a deal valued at approximately $150 million. The acquisition is aimed at giving organizations the ability to inventory AI applications, models, agents, and MCP connections, test for attacks, and block unauthorized actions.

The move reflects a shift in how AI security is being approached, moving from a one-time compliance assessment to a continuous control layer. This change has implications for executive strategy, IT and development teams, legal departments, and operations groups that manage risk and insurance requirements.
