What Vanta does well

Vanta is a compliance automation platform that excels at internal compliance: continuous monitoring of your own infrastructure, automated evidence collection for SOC 2/ISO 27001 audits, employee security training, and policy management. For organizations pursuing their own SOC 2 certification, Vanta streamlines the entire process. Their platform is well-designed, well-supported, and has earned its market position.

Where Vanta's vendor risk falls short

Vanta's vendor risk module relies primarily on security questionnaires sent to vendors. This means you're dependent on vendor response times (weeks), receiving self-reported answers (no independent verification), and limited to what the vendor chooses to disclose. Vanta doesn't independently investigate vendor risk — it helps you manage the questionnaire workflow.

What ThirdProof does differently

ThirdProof takes the opposite approach: nothing in the assessment depends on the vendor replying. Every assessment queries 27 public intelligence sources in parallel — sanctions databases, business registries, threat intelligence feeds, certification registries, SEC filings, and more. Results arrive in under 10 minutes, and every finding cites its exact source. Your auditor sees independently gathered evidence, not vendor self-attestations.

When to use Vanta, when to use ThirdProof, when to use both

Use Vanta when you're pursuing your own SOC 2/ISO 27001 certification and need to automate internal compliance evidence collection. Use ThirdProof when you need to assess vendor risk with independently verified intelligence. Use both when you want Vanta for your internal compliance program and ThirdProof for the vendor risk assessment that feeds into it. Many teams generate ThirdProof reports and upload them to Vanta as vendor evidence.

Common questions

Can ThirdProof replace Vanta?+
Not exactly — they solve different problems. Vanta automates your internal compliance program (SOC 2, ISO 27001). ThirdProof investigates your vendors' risk. If you're only looking for vendor risk assessment, ThirdProof is the focused solution. If you need both internal compliance automation and vendor risk, many teams use Vanta for the former and ThirdProof for the latter.
Does Vanta do vendor risk assessment?+
Vanta includes a vendor risk module built primarily around questionnaires — you send questions to vendors and manage their responses — with some automatic vendor discovery alongside it. Independent public-source investigation is not what it is designed around. ThirdProof takes the opposite approach: autonomous assessment across 27 intelligence sources without any vendor contact.
Can I use ThirdProof reports inside Vanta?+
Yes. Many teams generate a ThirdProof assessment, download the PDF report, and upload it to Vanta as vendor evidence. This gives you independently verified vendor intelligence within your Vanta compliance workflow.
How does pricing compare between ThirdProof and Vanta?+
Vanta does not publish a price. Buyer-reported contracts cluster around $20,000 a year — Vendr's median across 320 recorded purchases, with the spread running roughly $7,500 to $57,000 depending on headcount and modules (vendr.com, checked August 2026). Treat that as indicative of the market, not as a quote. ThirdProof is $399/month for 50 vendor investigations per month. The comparison isn't entirely apples-to-apples since Vanta includes internal compliance automation, while ThirdProof focuses specifically on vendor risk assessment.
Which should I buy first — Vanta or ThirdProof?+
If you're pursuing SOC 2 or ISO 27001 certification, start with Vanta for your internal compliance program. Add ThirdProof when you need to document vendor due diligence — which SOC 2 CC9.2 requires. If you only need vendor risk assessment and aren't pursuing your own certification, ThirdProof alone may be sufficient.
