Israeli AI Security Startup Bay Raises $50 Million to Secure Autonomous Agents

Tel Aviv-based startup Bay has officially launched with $50 million in total funding, including a $37 million Series A led by Battery Ventures. Founded in early 2026 by veterans of Israel's Unit 8200 and cybersecurity industry leaders, the company addresses the critical security risks posed by autonomous AI agents. As enterprises increasingly deploy agents to handle complex workflows, these systems can inadvertently expose sensitive data or misconfigure cloud environments while attempting to complete tasks. Bay’s platform acts as a real-time enforcement layer, intercepting agent actions via native hooks to verify them against assigned tasks and organizational policies. The system can block, approve, or request human intervention within milliseconds. With dozens of enterprise customers already onboard, including Micron and Wix, Bay aims to become a foundational security layer for the AI era, similar to the role of network firewalls in the early internet. The company plans to use the new capital to expand its engineering team in Israel and scale its sales operations globally.
