About Harmonic Security

Harmonic Security is the AI governance and control platform for the AI-first workforce. As employees adopt AI tools and hand work to autonomous agents in products like Claude Cowork, Claude Code, and OpenAI’s agents, Harmonic gives security teams visibility and control across browsers, desktops, and the agentic AI layer, including MCP clients and servers. Harmonic stops risky agent actions and prevents intellectual property from leaking to AI providers, without blocking the tools and workflows employees rely on to do their jobs.
