What Third-Party Risk
Management Software Actually Costs

Start with the vendors who publish a rate card. UpGuard lists $1,750/month billed annually for 50 monitored vendors, with additional vendors at $79/month (upguard.com/pricing/vendor-risk, checked August 2026). Everyone else is quote-only, but buyers do report what they paid. Aggregated contract data puts the median around $20,000 a year for Vanta and $25,000 for Drata, and about $24,000 for the security-ratings platforms SecurityScorecard and BitSight (Vendr transaction data, checked August 2026). Enterprise GRC suites — OneTrust, Archer, ServiceNow — vary far more than the others because you buy modules rather than a product; OneTrust's reported median is around $12,000 a year, and full multi-module deployments run many times that. Every one of those is an indication of the market, not a quote you can hold anyone to. ThirdProof publishes $399/month for 50 vendor investigations, with the first 5 free.

The spread across the category is scope, not assessment depth. Enterprise TPRM platforms are built for organisations with a dedicated compliance department of 10-20+ people, thousands of vendors, and complex governance workflows: risk registers, procurement integration, issue management, vendor lifecycle orchestration and continuous monitoring. None publish a rate card, so the number arrives with a sales process attached, and reported contracts vary by an order of magnitude depending on which modules you take. Those capabilities earn their price at 500 vendors. At 30, most of the spend goes to capabilities nobody opens — and someone still has to run the implementation project.

If you're a startup or a small team preparing for SOC 2 and assessing 10-50 vendors, you need three things: a vendor inventory, a documented risk assessment for each vendor, and evidence you can put in front of an auditor. You do not need governance workflow, a risk register, or a procurement module — those are what put enterprise platforms in a different price bracket, one you have to ask for. Paying suite prices for the assessment half is the most common way a small team overspends on TPRM.

SOC 2 CC9.2 doesn't require a platform — it requires evidence. Specifically: documented proof that you identified vendor risks, assessed their controls, and made informed decisions. That means a risk assessment per vendor with cited findings, a consistent methodology, and output an auditor can follow. That's what ThirdProof produces, without a GRC suite underneath it.

ThirdProof is the right call when you need a defensible vendor decision now, your auditor wants evidence rather than a platform, you're assessing roughly 5-50 vendors, and nobody on the team is going to run a six-month rollout.

It's the wrong call when continuous monitoring is the actual requirement, when you need a risk register and procurement workflow wired into the rest of the business, or when you're managing hundreds of vendors with a dedicated GRC team. At that point a broader suite earns its price, and ThirdProof is better used alongside one for fast initial assessment than instead of it.

Start with your vendor inventory — list every vendor that touches your data or operations. Prioritise by data sensitivity and business criticality. Run assessments on your highest-risk vendors first. Use the PDF reports as your vendor due diligence evidence file. You'll have a documented vendor risk program in an afternoon rather than a quarter.
