Harmonic Security Connectors

Harmonic Security delivers secure Model Context Protocol (MCP) connections between models and your internal systems. We monitor agent behavior, and step in with guardrails when agents attempt to take unauthorized actions or share sensitive data.

Harmonic Security Applications Summary

Complete Visibility into Agentic Workflows


You cannot secure what you cannot see. Automatically discover and inventory all MCP clients (e.g. Codex, Claude Cowork / Code, Cursor) and servers, whether they are official vendor builds or locally built tools.

  • Usage Analytics: Understand which employees are using which clients or servers and how frequently via centralized dashboards.
  • Invocation Logging: Capture detailed audit logs of every interaction between clients and servers for forensic analysis and compliance.

Granular Policy Enforcement & Data Protection


Move beyond coarse blocking. Define and enforce exactly what actions agents can take and what types of information they can share with each tool.

Harmonic delivers control of agentic actions triggered in coding environments like Claude Code, Codex CLI or Cursor, in desktop apps like Claude Cowork or ChatGPT desktop, and in web apps like Claude.ai or ChatGPT.com.

Intelligent Feedback & Remediation


Security controls should not break engineering workflows. When sensitive data is detected, Harmonic Connectors provide contextual, detection-specific feedback directly to the agent.

  • Agent Coaching: This feedback coaches the AI agent on why an action was blocked, allowing it to find a safe, alternative path to complete its task.
  • Reduce Friction: Enable safe AI adoption by resolving policy violations automatically without requiring manual intervention from the security team.

FAQs

Quick answers about Harmonic Security

Can Harmonic Security detect usage of OpenClaw?

Yes, Harmonic Security can detect usage of OpenClaw (as well as other workstation agents) via our endpoint agent.

How do Harmonic Connectors deploy?

Harmonic Connectors deploy locally via a lightweight gateway that runs on Windows, macOS, and Linux. Harmonic Connectors for Web AI use are added to to platforms like Claude and ChatGPT in seconds via system admins..

What is Harmonic Security's technical differentiator?

Harmonic uses purpose built small language models that understand user intent and sensitive data in milliseconds. This low latency analysis lets you enforce inline controls without slowing work down, rather than staying stuck in passive monitor mode.

"While we did understand what people were using — because we had that visibility — we didn't know how they were using it, and the data leakage was definitely a big one. ... That's when we went looking for outside help. ... It's literally hours to seconds. If we deploy a tool and it's covered by Harmonic Security, we have insight right away."
