Capsule Security is building a runtime trust layer for agentic AI, infrastructure that watches and governs AI agents while they actually run inside enterprise environments. As organizations connect agents to sensitive systems and data, Capsule's premise is that the riskiest moment is execution: an agent can be manipulated by prompt injection, drift into unsafe behavior, or attempt to exfiltrate data mid-task. Capsule aims to catch and stop that in real time.
The platform provides real-time visibility into agent actions and can block unsafe or unauthorized behavior before it is completed, rather than relying solely on pre-deployment testing or after-the-fact logs. A key design choice is that it does not require proxies, gateways, SDKs, or browser extensions, lowering the integration burden and letting security teams adopt it without re-architecting their agent stack.
Capsule was founded in 2025 by CEO Naor Paz, formerly of F5 and the Israeli intelligence Unit 8200, and CTO Lidan Hazout, formerly of SecuredTouch and Transmit Security. The company is headquartered in Tel Aviv and exited stealth in April 2026 with a $7 million seed round led by Lama Partners alongside Forgepoint Capital International.
The platform integrates with widely used agent and copilot tools, including Cursor, Claude Code, Microsoft Copilot Studio, ServiceNow, and Salesforce Agentforce, positioning Capsule as a security control plane that sits across the agents enterprises are already deploying. Its advisory board includes prominent security leaders such as Chris Krebs, the first director of CISA, and former CyberArk global CIO Omer Grossman.
Capsule operates in the fast-emerging agentic-AI security category, where investors are funding runtimes, identity, and control layers that make agents safe enough to deploy. Its differentiation rests on a runtime-focused, agentless architecture and a founding team with deep security and behavioral-detection experience.
