American AI risk management and information security company Vanta has acquired Israeli cybersecurity firm Pillar Security for approximately $150 million in a cash and stock deal. Pillar Security will become Vanta's research and development center in Israel, integrating its over 20 employees and founders into Vanta's operations, with a focus on AI security leadership.
Pillar Security, founded in 2023 by Ziv Karlinger and Dor Sarig, developed a system to help organizations map AI applications and autonomous agents, assess their vulnerability to cyberattacks, and monitor their real-time activity. The company had previously raised $9 million from investors including Shield and Ground Up. Its clients include major technology firms, financial institutions, and Fortune 500 companies.
The acquisition aims to bolster Vanta's capabilities in AI system control and governance, a sector Vanta entered in July with a successful early-access product. Pillar's technology will be integrated into Vanta's Agentic Trust platform, enabling organizations to set operational boundaries for AI agents, prevent real-time deviations, and document compliance with security policies and regulations.
Vanta CEO Christina Cacioppo stated that the acquisition will allow for the actual enforcement of policies on AI agent operations, not just their definition. Pillar CEO Ziv Karlinger added that the combined defense systems and Vanta's organizational risk picture will make the solution accessible to thousands of security teams globally.
This is Vanta's third acquisition, following Trustpage in 2023 and Riskey in 2025. The acquisition of Riskey, an Israeli startup focused on AI-based supply chain and third-party risk management, previously formed the foundation for Vanta's operations in Israel. Vanta, which serves over 20,000 clients and achieved an Annual Recurring Revenue (ARR) of $300 million in April, sees this latest acquisition as a significant expansion of its Israeli presence.
