Capsule Security, an Israeli startup, has launched with $7 million in funding to secure AI agents during their runtime operations. The company's platform monitors AI actions in real time, enforcing guardrails to prevent manipulation and data exfiltration.
Founded by former F5 and Israeli military intelligence veterans, Capsule targets the security gap between an AI agent receiving a prompt and executing an action. Co-founder and CEO Naor Paz stated that AI agents are becoming privileged users acting at machine speed, creating a governance challenge for security teams.
The platform operates without proxies, gateways, or SDKs and supports various AI tools, including Microsoft Copilot Studio and Salesforce Agentforce.
Capsule Security was also a finalist in a recent startup accelerator, pitching its AI-native innovation to investors. The seed funding round was led by Lama Partners, with participation from Forgepoint Capital.
"Security leaders understand that legacy tools were never designed to interpret intent, context and real-time behavior," said Ron Zalkind of Lama Partners.
The company also revealed it discovered two zero-day vulnerabilities in major agent platforms: "ShareLeak" in Microsoft Copilot Studio and "PipeLeak" in Salesforce Agentforce, both of which have been patched.
