Short verdict: which one fits you

A fit guide, not a ranking. We don't pick an overall winner.

Choose Comp AI if…

  • you want the larger published integration catalogue (580+ vs 400+) [6]
  • you need to inspect the code or self-host [6]
  • you want a faster rollout (1 month vs 2 months on G2) [1]
  • you match its stated best fit: engineering-led teams that value inspectable code or the option to self-host [3]

Choose Vanta if…

  • a lower typical price matters most ($20,000 median; Comp AI doesn't publish one) [2]
  • you want more choice of audit firm (40 directory firms) [4]
  • hourly default testing matters for your highest-risk controls [5]
  • you need an auditor workspace confirmed as standard [8]

Neither runs the audit itself. If you want software and audit from one provider, compare Thoropass. [3]

  • Full SCIM account lifecycle documented. [3]

Five tests to run on both before you sign

  1. Connect your three most important systems

    Use a trial or sandbox to connect your cloud provider, identity provider and code host, and check that each produces evidence without manual uploads.

  2. Ask your auditor which one they work in

    An auditor who already works in a platform usually needs less back-and-forth on evidence.

  3. Get both quotes on the same written scope

    Employees, frameworks, modules, support level, contract term, renewal cap, and the audit as its own line.

  4. Check what is an add-on

    SSO, SCIM, extra frameworks, questionnaires and trust-centre features are often tier-gated. Ask for the full price of the scope you need.

  5. Ask how you would leave

    Confirm you can export policies, evidence with timestamps and test history, and whether read-only access continues after the contract ends.
