Jerusalem, 9 November, 2026 (TPS-IL) — American cybersecurity company Vanta has signed an agreement to acquire Israeli AI security startup Pillar Security for approximately $150 million, Israeli media reported Monday. The deal combines cash and stock.

Vanta, which provides a platform for managing security, risk, and compliance, is valued at $4.15 billion.

Following the acquisition, Pillar will become Vanta’s Israeli research and development center, with its technology integrated into Vanta’s Agentic Trust platform, which serves more than 20,000 customers. Pillar’s more than 20 employees will join the new development center, while its founders will remain at Vanta and lead AI security development.

Pillar’s technology maps an organization’s AI agents, conducts simulated attacks to identify vulnerabilities, and blocks agents in real time when they exceed authorized permissions. The acquisition addresses growing risks as AI agents move beyond answering questions to performing autonomous tasks involving sensitive corporate systems and data.
