Agent discovery & inventory

Harmonic Security

Browser-extension product that inventories employee AI usage by monitoring in-browser web traffic: which AI applications are used, whether the session uses a personal or corporate account, embedded AI features in sanctioned SaaS, and AI browsers. It also nudges or blocks sensitive prompt content. Coverage stops where the managed browser does.

Capabilities and evidence

Support labels reflect the supplied research. Documentation and vendor claims are not independent product tests. “Not established” means the researcher did not find support; it does not prove a capability is absent.

Documented by provider

The browser extension monitors end-user web traffic and reports usage metadata (user, application, host, path, timestamp) plus filtered HTTP request payloads to identify which AI applications are in use.

Limit: Support documentation describes data captured; it does not quantify detection coverage of AI apps or handling of non-browser AI clients.

Vendor claim
