Secure Claude use across the workforce
Give employees room to use Claude while keeping sensitive data, connected systems, and agent actions within policy.
We Make Protecting Claude Simple
Employees use Claude as the primary interface through which they do their jobs. It's a powerful productivity shift, but it creates an entirely new set of security and governance challenges.
Harmonic Security makes it simple to understand exactly how your company is using Claude, and provides context-aware guardrails to protect sensitive information and govern the actions of agents.
Understand Exactly How Claude is Used
Discover Claude usage across all surfaces that employees access it. Monitor usage even when employees use free or personal plans and set plan-specific policies.
Understand exactly how employees use each tool (down to the task level), including which use cases lead to the riskiest behaviors and which are driving productivity.
Protect Sensitive Information in Context
Ensure employees never share information they shouldn't with Claude. Harmonic Security's models are able to read through conversations just like a human would and understand what is sensitive or not in context.
Deliver inline controls across the web and desktop with clear explanations for employees of what triggers each warning or interventation.
Govern Agents Without Interrupting Workflows
Monitor exactly what tools Cowork or Claude Code agents are connecting to and what actions are being taken.
When agents attempt actions that are not permitted, Harmonic intervenes in real time and explains exactly why an action is being prevented without stopping the workflow, so both humans and agents remain on task.

You can, but it won't hold. Employees will access Claude on personal devices, use mobile hotspots, or route around network controls. The only durable answer is visibility and policy at the point of use — in the browser, on the endpoint, and at the MCP layer.
