Capsule Security Secures $7 Million in Seed Funding
Capsule Security has officially emerged from stealth, announcing the successful closure of a $7 million seed funding round. This investment, led by Lama Partners with support from Forgepoint Capital International, will accelerate the development of Capsule’s innovative AI runtime protection platform for enterprise agents. As organizations increasingly deploy AI agents across critical systems, the need for robust security to monitor and control these high-speed, privileged users has never been greater.
Addressing the Security Risks of AI Agents
With the proliferation of AI-driven tools in the enterprise space, Capsule Security is targeting a crucial gap in the security landscape—protecting the runtime behavior of AI agents. Unlike traditional security solutions, which often focus on perimeter defenses or static code analysis, Capsule’s AI runtime protection platform operates directly within the execution layer of AI workflows. This unique approach allows the platform to monitor, evaluate, and control the actions of AI agents in real time, ensuring that malicious behavior, unintended actions, and data exfiltration are promptly identified and prevented.
Innovative Runtime Security Layer
The core of Capsule’s technology is a runtime security layer purpose-built for the dynamic nature of AI agents. These agents, which act as privileged users at machine speed, can introduce significant risks if left unchecked. Capsule’s platform delivers real-time visibility into agent activities, enforcing guardrails to stop risky actions before they cause harm. By evaluating agent behavior in context and blocking unsafe operations, Capsule provides enterprises with auditable telemetry for governance and compliance—a key requirement as regulations around AI use continue to evolve.
Seamless Integration and Broad Platform Support
One standout feature of Capsule’s solution is its seamless integration with existing enterprise tools. Unlike many legacy security products, Capsule does not require proxies, gateways, or additional infrastructure. The AI runtime protection platform supports a wide range of agent platforms, including Cursor, Claude Code, Microsoft Copilot Studio, ServiceNow, and Salesforce Agentforce. This flexibility ensures that organizations can secure both third-party and custom AI deployments without disrupting their existing workflows.
Recognition and Industry Impact
Capsule Security’s innovative approach has already gained recognition within the cybersecurity community. The company was recently named a finalist in a prestigious startup accelerator program led by CrowdStrike, Amazon Web Services, and NVIDIA. This early validation underscores the growing demand for comprehensive runtime protection as enterprises scale their adoption of agent-based systems.
Leadership and Vision
Founded in 2025 by Naor Paz and Lidan Hazout in Tel Aviv, Capsule Security is guided by a team with deep technical expertise and a clear vision for the future of AI security. CEO Naor Paz emphasizes the critical nature of runtime security, stating, “AI agents are rapidly becoming a new class of privileged user in the enterprise, acting at machine speed with minimal oversight. Capsule closes the dangerous runtime gap by enforcing trust at execution, allowing teams to innovate with AI while maintaining strict control.”
Industry Experts Weigh In
Industry leaders have voiced strong support for Capsule’s mission. Chris Krebs, former Director of CISA, highlights the challenge: “Legacy tools weren’t built to monitor what happens between prompt and action—that’s the runtime gap. Capsule closes it.” Investors like Ron Zalkind, Founding General Partner at Lama Partners, note the importance of securing agentic environments, stating, “Security leaders understand that legacy tools were never designed to interpret intent, context, and real-time behavior, which are essential for securing dynamic AI agents.”
The Future of AI Runtime Protection
As enterprises continue to embrace AI-driven automation, the risks associated with autonomous agents will only increase. Capsule Security’s AI runtime protection platform is poised to become a foundational layer for securing next-generation enterprise systems. By providing real-time visibility and control, Capsule enables organizations to confidently adopt AI agents while ensuring compliance, governance, and operational trust.
With its recent $7 million seed funding, Capsule Security is well-positioned to address the challenges and opportunities of securing AI agents in complex enterprise environments. As the agentic AI ecosystem evolves, runtime protection will be essential for organizations seeking to balance innovation with robust security controls.
