Capsule Security has officially emerged from stealth mode, announcing a $7 million seed funding round led by Lama Partners and Forgepoint Capital International. With this launch, the Tel Aviv–based startup is stepping into a rapidly evolving cybersecurity segment focused on safeguarding AI agents operating within enterprise environments.
As organizations increasingly adopt AI-driven automation, Capsule Security aims to address the growing risks associated with autonomous agents accessing sensitive data, executing workflows, and interacting with internal systems. Notably, the company highlighted that more than 80% of Fortune 500 organizations are already leveraging AI agents developed through low-code and no-code platforms—signaling a major shift in enterprise operations.
However, this rapid adoption has also introduced new vulnerabilities. Unlike traditional software or human users, AI agents can act at machine speed and make decisions with minimal oversight. As a result, Capsule argues that businesses must treat AI agents as a new class of privileged users.
“AI agents are quickly becoming a new class of privileged user in the enterprise, except they can act at machine speed and they do not behave like deterministic software,” said Naor Paz, Chief Executive Officer and Co-Founder, Capsule Security.
Paz continued, “That creates a dangerous gap between what security teams can govern today and what agents can do in production. Capsule closes that gap by enforcing trust at runtime, inside the execution path, so teams can move fast with agents while staying in control of what those agents can access and execute.”
Research Findings Highlight Emerging Risks
Alongside its launch, Capsule revealed critical research findings that underline the urgency of securing AI agents. Specifically, the company discovered vulnerabilities such as ShareLeak in Microsoft Copilot Studio and PipeLeak in Salesforce Agentforce.
While ShareLeak has already been patched and assigned CVE-2026-21520, PipeLeak demonstrated how malicious inputs from lead forms could manipulate agent behavior and trigger unintended actions. Therefore, these vulnerabilities illustrate a broader issue—external inputs can influence AI agents in ways that compromise security.
To further strengthen defenses, Capsule introduced ClawGuard, an open-source enforcement tool for OpenClaw. This solution adds an additional checkpoint before AI agents execute tool calls, thereby reducing the risk of unsafe actions in open frameworks.
Product Innovation Focused on Runtime Security
Unlike traditional security solutions, Capsule’s platform operates without relying on proxies, gateways, SDKs, or browser extensions. Instead, it integrates directly into existing enterprise systems and supports platforms like Cursor, Claude Code, Microsoft Copilot Studio, ServiceNow, and Salesforce Agentforce.
Importantly, the platform focuses on runtime protection—monitoring AI agent behavior as it happens. It evaluates actions in real time and can block unauthorized or risky activities before they are completed. At the same time, it generates telemetry data that supports governance, compliance, and incident investigation.
Additionally, Capsule has earned recognition as a representative vendor in Gartner’s market guide for “guardian agents,” a category designed to oversee and secure other AI systems.
“AI agents are a new class of privileged user, operating at machine speed with minimal oversight,” said Chris Krebs, Advisor, Capsule Security. “Legacy tools weren’t built to monitor what happens between prompt and action-that’s the runtime gap. Capsule closes it.”
Strong Backing Reflects Market Demand
The funding round reflects increasing investor interest in AI security solutions that go beyond traditional approaches. As enterprises grant AI systems broader access to internal tools, investors are prioritizing technologies that can monitor intent, context, and behavior in real time.
Ron Zalkind, Founding General Partner at Lama Partners and a board member at Capsule Security, said the investment was driven by the shift in how software is being built and operated through AI-driven automation.
“Agents have the ‘superpower’ to write and deploy code at unprecedented rates, fundamentally changing how software is built and operated,” said Ron Zalkind, Founding General Partner, Lama Partners, and Board Member, Capsule Security.
Zalkind said, “With that level of power comes a new responsibility to secure it. Security leaders understand that legacy tools were never designed to interpret intent, context, and real-time behavior, which are essential for securing dynamic agentic environments. From day one, Naor and Lidan have combined deep technical rigor with clarity of vision to build a platform that allows organizations to confidently adopt AI agents while stopping dangerous actions before damage is done.”
Furthermore, Damien Henault of Forgepoint Capital International emphasized Capsule’s technical innovation.
“Capsule fine-tuned Small Language Models (SLMs) to create a multi-agent system of ‘Guardian Agents’ that can protect AI with AI, covering both posture and low-latency runtime protection. The team is the strongest of the agent-space players, having expertise in both traditional security and deep familiarity with emerging protocols like MCP and Skills,” said Damien Henault, Managing Director/Partner, Forgepoint Capital International, and Board Member, Capsule Security.
