Endpoint AI Visibility and Control For Everywhere Your Team Needs It
AI work has moved past the browser. Extend visibility and control to the desktop apps, IDEs, CLIs, local models, and inference APIs your workforce actually uses.
Protection Where Work Actually Gets Done
From Claude Cowork, to Cursor, to Open AI Codex, much of your team’s AI usage lives on tools your browser can't see. The Harmonic Endpoint Agent closes that gap. It identifies every native AI app, AI-first IDE, CLI tool, locally hosted model, and direct inference API call running on employee devices, and surfaces all of it in the same Harmonic platform your team already uses for browser-based AI.
Visibility Across Every Off-Browser AI Surface
Desktop apps, AI-first IDEs, CLI tools, IDE plugins, and locally hosted models all sit outside the browser and outside the visibility of most security stacks. Harmonic covers the full set, from Claude Desktop and ChatGPT Desktop to Cursor, Claude Code, GitHub Copilot, Ollama, and the MCP servers running on developer machines.
Every native AI tool appears alongside browser-based apps in your Harmonic portal, scored by the same risk model and managed through the same approval workflows. One view of every AI tool your workforce uses, regardless of where it runs.
Know Exactly Which Models and Providers Are in Use
Knowing an employee uses Cursor isn't the same as knowing whether Cursor is calling Anthropic, OpenAI, DeepSeek, or a self-hosted model. The application is only half the picture. The provider behind it determines the actual data risk.
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. That same detection catches AI activity from custom scripts and homegrown agents that no app fingerprint would identify on its own.
Prompt-Level Depth Where It Matters Most
Discovery tells you what's running. Prompt-level analysis tells you what's actually being shared. Harmonic reads the full content of every interaction with the AI tools running on employee devices, detects sensitive data in context, and coaches employees away from risky behavior in real time.
The Harmonic MCP Gateway pairs with the Endpoint Agent to extend that same precision to agentic workflows, giving you real-time visibility and control over the information desktop tools can share with third parties and the actions they can take on behalf of your team.

FAQs
Quick answers about Harmonic Security
EDR monitors everything and sends broad telemetry to the cloud, leaving you with generic data you have to interpret to answer AI questions. The Harmonic Endpoint Agent only watches processes and hosts tied to known AI apps and APIs, so instead of raw data you get the actual answers about AI usage. It runs alongside your existing EDR.
No. Pattern-matching DLP cannot tell a draft email from a deal memo because prompts are unstructured and contextual. Static rules either flood teams with false positives or get ripped out entirely. We classify the meaning of the work, not the shape of the string. That is what lets us govern inline, where DLP can only monitor.
SASE inspects network traffic to known AI domains. Useful, but it misses everything that does not cross the network: Claude Desktop, Cursor, local MCP servers, embedded AI inside Canva or Salesforce, free-tier accounts on personal devices. Most shadow AI exposure happens on personal devices that never touch the corporate network, which is also where SASE has no jurisdiction. We sit on the device and inside the AI surface itself. That is why we can govern where SASE can only observe, and why we cover the agent layer SASE never reaches.
Yes. Harmonic detects and monitors Claude Desktop as a native application on both macOS and Windows, giving you visibility that browser-only tools miss entirely.
