Comparison
Provebase vs Vanta Questionnaire Automation
If you already use Vanta, this is a "both," not an "either." Provebase connects to your Vanta evidence read-only and uses it as the grounding for every answer — so you keep Vanta as your compliance platform and add a specialized answering agent on top. Where Vanta’s questionnaire feature is one capability inside a broad platform, Provebase is built solely around answering: confidence-gating, source citations, refusal when it isn’t sure, and filling portals inside your own logged-in session.
Provebase is built Drata-first and supports Vanta as a read-only evidence source. It complements your Vanta subscription rather than replacing it.

FAQ
Provebase vs Vanta Questionnaire Automation, answered
- Does Provebase replace Vanta?
- No. Provebase uses your Vanta evidence read-only and complements it — Vanta stays your compliance platform. Provebase adds a specialized questionnaire-answering agent with citations, confidence-gating, and portal filling.
- I already pay for Vanta’s questionnaire feature — why add Provebase?
- Because Provebase does one thing and does it strictly: it cites every answer to a source, refuses to guess below its confidence threshold, and never submits without your sign-off. If you want that discipline on top of your Vanta evidence, the two work together.
