Harmonic Security has launched the MCP Gateway, a locally installed, developer-friendly solution designed to provide security teams with comprehensive visibility and control over their organization’s agentic AI ecosystem. This innovative gateway intercepts all MCP (Model Context Protocol) traffic, allowing teams to discover which AI clients and servers are active, enforce granular security policies to block risky behaviors, and utilize Harmonic’s sensitive data models to prevent critical intellectual property and sensitive information exfiltration.
MCP Gateway offers complete visibility into model context protocol traffic across AI tools and systems.
Enables enforcement of detailed policies to block risky client activities and data movement.
Protects against sophisticated threats such as workflow hijacking, credential theft, and tool poisoning.
Facilitates transparency and security via an open standard for AI model interactions.
Supports proactive prevention by moving from reactive alerting to real-time risk blocking.
Developed with security and governance in mind, empowering teams to safely innovate with AI.
With the rise of agentic AI, enterprises face new invisible attack surfaces, including complex threats beyond mere data leaks. Harmonic Security’s MCP Gateway delivers the governance and control tools needed to manage these risks effectively. The gateway transparently monitors MCP traffic, giving security teams a clear picture of AI tool interactions, enabling prompt action to block malicious or risky activities before damage occurs.
MCP serves as an open protocol fostering consistency and security in AI ecosystems by defining how AI models communicate securely with external systems, APIs, and data sources. This common framework allows enterprises to build and expand AI environments with reliability and trust, essential for safe adoption of agentic AI at scale.
Bryan Woolgar-O’Neil, CTO and co-founder of Harmonic Security, highlights the increasing challenges security leaders face and the critical role MCP Gateway plays in providing visibility and control. Customers like Michael Janielis of Advisor360 commend Harmonic for proactively addressing AI-driven workflow risks, enabling teams to innovate while maintaining security confidence.
