Overview
Helmet Security is the first end-to-end security platform built to protect enterprises from rapidly evolving agentic AI communications. Today, MCP is the leading method enabling AI agents to plug directly into business systems and Helmet provides instant, installation-free visibility into where and how those MCP connections are operating by integrating directly with existing EDR tools. The platform continuously discovers and manages MCP servers, bringing them under enforced policy so security leaders can identify risky activity, prevent unsanctioned or overprivileged workflows, and react instantly to new connections. As AI-to-AI communication patterns expand beyond MCP, Helmet is built to secure every next step, ensuring enterprises can innovate safely now and into the future.
