SUPERWISE® Sentinel is a focused AI gateway for requests routed from supported employee and application setups. Harmonic Security documents broad workforce coverage through a browser extension, endpoint agent, MCP gateway, and telemetry integrations. Harmonic is the broader employee AI governance product; Sentinel is the narrower gateway choice.
