According to Calcalist, Pillar, founded in 2023 by Ziv Karliner and Dor Sarig, has developed a platform that lets organizations discover their AI systems and agents, test their resilience against attacks and protect them while they run, including blocking unauthorized actions in real time. Its customers include Fortune 500 companies as well as technology and financial firms. The company has raised $9 million since its founding, and its seed round was led by Shield Capital.
All of Pillar's more than 20 employees are expected to join the new R&D center, and the founders will lead Vanta's AI security business. The technology will be integrated into Vanta's platform, which serves more than 20,000 customers. Vanta launched an AI governance product in July 2026, and says demand for its early-access program was six times the available places.
According to Vanta, the acquisition is meant to connect the policies that define how AI systems should behave with technical controls that test and restrict what they actually do.
