Vanta agrees to buy AI agent security startup Pillar, in a deal reported at $150 million
Pillar's runtime protection and red-teaming for AI agents will be folded into Vanta's compliance platform through 2027; the companies did not disclose the price.
Why it matters
Vanta sells compliance automation and says it has passed 20,000 customers; Pillar, founded in 2023 by Ziv Karliner and Dor Sarig, tests AI agents and blocks unauthorised actions while they run. Calcalist puts the price at about $150 million, and Pillar's team of more than 20 will become Vanta's Israeli R&D centre. The deal reflects buyers wanting proof that autonomous agents follow written policy, not only documents. Vanta plans AI inventory and runtime monitoring in January 2027 and runtime enforcement by summer.
