Harmonic Security Platform

What it does

The Harmonic Security Platform is an AI governance and control layer that lets enterprises adopt generative AI without exposing sensitive data. In place of pattern-matching Data Loss Prevention (DLP) rules, purpose-built small language models classify the intent and data context of every AI interaction in under 200 milliseconds, enforcing policy inline at the browser, desktop, and agent layers where network proxies and Secure Access Service Edge (SASE) tools cannot see AI activity.

How it works

Three modules share one control plane. Harmonic Explore inventories AI usage against a weekly updated catalog of more than 1,000 AI tools, distinguishing personal from corporate accounts and surfacing embedded SaaS AI and shadow AI. Harmonic Guide intervenes inline in browsers and desktop apps such as Claude Desktop and Cursor, nudging users, requiring justification, redirecting to sanctioned tools, or blocking before data leaves the device. Harmonic Command extends governance to agentic workflows through a local Model Context Protocol (MCP) gateway that inventories MCP clients and servers, enforces tool-level policy, and captures audit logs of every interaction.
