About Harmonic Security

Harmonic Security sells AI Governance and Control (AIGC), a control layer that secures and enables the AI-First workforce. Harmonic Security describes a platform that classifies every AI task, discovers why it is used, and controls it in real time. Harmonic Command covers workforce AI use across supported browsers, desktop applications, command-line tools, AI APIs, and agentic workflows that use MCP. Harmonic Command coverage includes ChatGPT, Claude, Copilot, Gemini, Cursor, and more than 1,000 web AI tools.[1][2][3]

Harmonic Command gives security teams visibility into how employees and agents use AI, plus controls for using the tools safely. Supported OpenTelemetry sources and the local MCP Gateway extend Harmonic coverage to additional native, command-line, and MCP activity. The Harmonic MCP Gateway pairs with the Endpoint Agent and applies to agentic workflows. The MCP Gateway runs on Windows, macOS, and Linux.[2][3][4][6]

The Harmonic Endpoint Agent identifies every native AI app, AI-first IDE, CLI tool, locally hosted model and direct inference API call running on employee devices. The Harmonic Endpoint Agent detects Claude Desktop, Claude Code, Claude Cowork and OpenAI Codex on macOS and Windows. Harmonic identifies connections to inference endpoints like OpenAI, Anthropic, Bedrock and Azure AI Foundry, and ties each connection back to the process and user that initiated it. The Endpoint Agent identifies locally hosted models such as Ollama on employee devices and ties that activity to the process and user behind it.[6]

Harmonic secures AI use in the browser with real-time visibility and control over how employees use AI tools. Harmonic identifies the specific account type and subscription plan in use. The Harmonic browser extension finds AI features running inside web apps, such as Magic Write in Canva. Harmonic can warn users as they are about to paste sensitive data, ask for a business justification, or steer them from an unsafe free tool to a sanctioned alternative. The Harmonic browser extension supports Chrome, Edge, Firefox and Safari, plus other Chromium browsers including Arc, Brave, Vivaldi, Island and Genspark.[7]

Harmonic Usage Intelligence groups prompts, files, responses, and supported agent actions into coherent tasks and organization-specific use cases, with views by department, employee, application, approval status, and time. Harmonic builds an inventory of the AI apps a workforce uses, who uses them and for what work. Harmonic records which tools are approved, how policy was applied, what was coached or blocked, and where sensitive data was exposed. Harmonic offers configurable retention, role-based access, employee masking and EU or US hosting. Harmonic does not train on customer data.[5][8][9]

Harmonic uses purpose-built small language models that read the whole prompt or file and interpret the nuance of natural language. Harmonic lets customers enforce enterprise accounts where data is ring-fenced, or restrict uploading corporate context into personal accounts. Harmonic can prevent the upload of protected health information and personally identifiable information to non-compliant models. Harmonic Security says it works with health systems, hospitals, payers and life sciences companies. Harmonic Security says it works with insurance carriers, brokers, MGAs and reinsurers. Harmonic can be deployed through Intune, Jamf, Kandji, or Group Policy.[1][2][3][4][5][8][10][11][12][13]
