FillTrust is an AI security questionnaire automation service that drafts answers to vendor security questionnaires (CAIQ, SIG, ISO and similar) from a company's own SOC 2 report, ISO certificate, policies, pen test summaries and answer library. Every drafted answer cites the source passage it came from, and answers the evidence does not support are left blank rather than invented. The product also offers a free hosted Trust Center, a browser extension, and a read-only MCP server that exposes the FillTrust guidance corpus to assistants over HTTP.
