Capsule Security Raises $7 Million to Protect Enterprise AI Agents

Tel Aviv startup Capsule Security has emerged from stealth with a $7 million seed round led by Lama Partners and Forgepoint Capital International, reports SecurityBrief. The company’s platform monitors and controls AI agents as they interact with enterprise systems, addressing risks from unauthorized access, data exposure, and automated workflows.

Capsule’s system provides real-time oversight of AI agents without requiring proxies, gateways, SDKs, or browser extensions. It integrates with tools such as Cursor, Claude Code, Microsoft Copilot Studio, ServiceNow, and Salesforce Agentforce. The company describes its product as a “runtime trust layer” that enforces control during execution, ensuring agents perform only authorized actions.

Alongside its launch, Capsule disclosed two vulnerabilities affecting major AI platforms: ShareLeak in Microsoft Copilot Studio, now patched and assigned CVE-2026-21520, and PipeLeak in Salesforce Agentforce. The firm also released ClawGuard, an open-source tool that adds checkpoints before agents execute tool calls.

Capsule was founded in 2025 by CEO Naor Paz and CTO Lidan Hazout. Its advisory team includes Chris Krebs, former Director of CISA, and several former CISOs from global companies. The company has been listed in Gartner’s market guide for “guardian agents,” systems built to oversee and secure other AI agents in enterprise environments.
