Vanta will buy Israeli AI security firm Pillar for $150 million
From January, Vanta plans to add tools from Pillar to its platform, which test AI agents and stop them.
Vanta, a US company, makes a software platform for security, risk and compliance management. It signed an agreement to buy Pillar Security, an AI security company in Israel, for about $150 million in cash and shares. Pillar makes software that finds AI agents, tests them against attacks, and stops them if they go out of limits.
How it works
Pillar finds the AI systems and agents of a company. It tests how they hold against attacks and protects them while they operate. Vanta plans an AI inventory tool for January. It will map AI apps, models, agents and servers, and connect them to owners and risks.
The numbers
Pillar raised $9 million. Vanta serves more than 20,000 customers. Its research says 65% of leaders use agents more than they know how to control them. Less than half have a framework to grant or limit AI autonomy.
Pillar researchers found methods to bypass security in coding tools such as Cursor and Codex. The vendors patched them.
What is not known
The source gives no test results for Pillar. It gives no date for the end of the deal. Vanta says that it will add the technology during 2027.
Insight: Vanta buys the power to stop agents
Pillar also found a vulnerability in Unsloth that lets attacker code operate when a model loads. Vanta CEO Christina Cacioppo says a policy document does not show that AI follows its rules. This reads as a move to hold the test and stop step, which auditors then accept as proof. Look for rivals such as CrowdStrike to do the same.
