Before the list, the criteria that actually separate these tools:
Almost every tool below starts the same way: someone adds a vendor, sends a questionnaire, and trusts the answers. That works for the vendors you know about — but it misses the ones you don't.
The fastest-growing third-party risk today is shadow AI — employees pasting customer data into ChatGPT, using an unsanctioned AI note-taker, or adopting a niche tool no one in security has heard of. None of those show up in a manual vendor list. As you read the comparison, weigh this: does the tool discover your third parties from real usage, or just organize the ones you remembered to add?
Best for: teams whose biggest exposure is data and AI, not paperwork.
Strac's TPRM module is part of Strac Comply and sits on Strac's data-security layer. That foundation changes what's possible: Strac discovers vendors and AI tools from real data flows, scores each by the sensitive data it actually touches, runs AI-powered security reviews, and can enforce offboarding by revoking access and deleting shared data. It's the only option here that treats the data itself as the source of truth — which also makes it strong on shadow AI and GenAI risk.
Best for: startups and SMBs already using Vanta for SOC 2.
Vanta's vendor risk management automates questionnaires and uses AI to analyze SOC 2 reports and DPAs, with a "TPRM Agent" that monitors vendors for breaches and material changes (Vanta). If you already run your compliance program in Vanta, its TPRM module is a natural extension — though discovery is limited to the vendors you connect or add.
Best for: compliance-led teams that want vendor risk inside their audit platform.
Drata's vendor risk module includes assessment workflows and basic vendor discovery, backed by 250+ integrations and continuous control testing (Drata). Like Vanta, it's strongest as part of a broader compliance program.
Best for: large enterprises with complex, multi-domain GRC needs.
OneTrust is a full governance, risk, and privacy suite with comprehensive TPRM — vendor onboarding workflows, scoring engines, and continuous monitoring. It's powerful and deep, with the budget and implementation effort to match.
Best for: continuous external security ratings.
SecurityScorecard rates vendors' external security posture and pairs it with questionnaires, so you get an outside-in view that updates continuously. It's a strong monitoring signal, though it sees the vendor's external surface rather than the data they touch inside your environment.
Best for: dedicated, assessment-heavy TPRM programs.
Prevalent is a long-standing standalone TPRM platform built around assessments, a questionnaire library, and continuous monitoring — a fit for mature programs that want a purpose-built tool rather than a module.
It depends on your stack. Vanta and Drata are great if you already use them for compliance; OneTrust suits large enterprises; SecurityScorecard excels at external ratings; and Strac is the strongest option when your biggest exposure is data and shadow AI, because it discovers vendors from real data flows.
Commonly cited leaders include Strac, Vanta, Drata, OneTrust, SecurityScorecard, and Prevalent (Vanta).
A standalone TPRM platform (like Prevalent) is purpose-built for vendor risk; a compliance platform's module (Vanta, Drata) adds TPRM to a broader SOC 2/ISO program. Strac is a module of Strac Comply but uniquely backed by a data-security layer.
Most don't. Strac discovers shadow AI and shadow IT from actual data flows, so you can bring unsanctioned tools under management instead of finding out about them after an incident.
Effectively yes — SOC 2's CC9 criteria require vendor risk assessment and oversight, and TPRM software gives you the assessments, documents, and monitoring records auditors expect. The same is true for ISO 27001 and Reg S-P.
The best third-party risk management software for you comes down to one question: do you mostly need to organize the vendors you already know about, or do you need to discover the ones you don't? Vanta, Drata, OneTrust, SecurityScorecard, and Prevalent are all strong at the former.
Strac is built for the latter — discovering shadow IT and shadow AI from real data flows, scoring vendors by the data they actually touch, and enforcing offboarding, all inside Strac Comply. Book a demo and we'll show you the vendors and AI tools already touching your data.
