Why Harmonic for the endpoint
How Harmonic secures AI outside the browser
From Claude Cowork to Cursor to OpenAI 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 platform your team already uses for browser-based AI.
01App discovery
See every AI tool running on employee devices
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 portal, scored by the same risk model and managed through the same approval workflows.
02Providers
Identify the model provider behind each AI tool
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 no app fingerprint would identify.
03Prompt inspection
Catch sensitive data in prompts and agent actions
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 on employee devices, detects sensitive data in context, and coaches employees away from risky behaviour in real time.
The Harmonic MCP Gateway pairs with the Endpoint Agent to extend that precision to agentic workflows, covering what desktop tools can share with third parties and the actions they can take on your team’s behalf.

Frequently asked questions
Endpoint AI security FAQ
Short, direct answers to what security and IT teams ask before bringing Harmonic in.
How is Harmonic’s endpoint agent different from CrowdStrike or other EDR tools?
EDR monitors processes running on the endpoint and detects malware. It has minimal visibility into what employees actually do inside AI tools on the desktop: it knows an application is running, and it can block it entirely, but it cannot provide the task-level intelligence and granular guardrails needed to use AI safely.
Is Harmonic just traditional DLP applied to AI prompts?
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. Harmonic classifies the meaning of the work, not the shape of the string, which is what lets it govern inline where DLP can only monitor.
How is Harmonic different from Zscaler, Netskope and other SASE tools?
SASE inspects network traffic to known AI domains. That is 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. Harmonic sits on the device and inside the AI surface itself, so it can govern where SASE can only observe.
Can Harmonic see local models like Ollama that never touch the network?
Yes. The Endpoint Agent identifies locally hosted models such as Ollama on employee devices and ties that activity to the process and user behind it. Network tools and SASE can’t see this, because the traffic never leaves the laptop.
Does Harmonic secure Claude and OpenAI Codex on the desktop?
Yes. The Harmonic Endpoint Agent detects Claude Desktop, Claude Code, Claude Cowork and OpenAI Codex on macOS and Windows. Each one appears in the same inventory as your browser-based AI tools, tied to the user and the model provider behind it, and is covered by the same prompt-level guardrails. Browser-only tools miss these apps entirely.
