If you're searching whether Vanta tracks vendor DPA changes, here's the honest answer up front: Vanta is excellent at what it does, and continuous vendor-document monitoring isn't really it. This page explains the distinction, because the two tools solve different halves of the same problem.
What Vanta does well
Vanta is a governance, risk, and compliance (GRC) platform. It automates the heavy machinery of getting and staying compliant:
- Evidence collection and control monitoring across your own systems
- SOC 2, ISO 27001, HIPAA, and other framework automation
- A vendor inventory with security reviews and risk ratings
- Auditor collaboration and continuous control checks
For running your compliance program, it's a strong platform. None of what follows is a knock on it.
The specific gap
Vanta's vendor module is built around onboarding and periodic review: you add a vendor, capture their security posture, assign a risk rating, and revisit it on a cadence. That captures a vendor at points in time.
What it doesn't do is sit on each vendor's public privacy policy, DPA, and subprocessor list every day and tell you the moment the text changes in a way that matters — a new subprocessor, a shortened breach-notification window, a new AI-training clause, a jurisdiction added. Between review cycles, those changes happen silently, and the periodic-review model isn't designed to catch them as they land.
That continuous-monitoring layer is the gap. It's narrow, but for CC9.2 vendor-management evidence it's increasingly the part auditors probe.
How they fit together
| Vanta | Thorgate | |
|---|---|---|
| Scope | Full GRC program | Vendor document monitoring only |
| Your own controls & evidence | Yes | No |
| Vendor inventory & risk rating | Yes | No |
| Continuous DPA / subprocessor monitoring | Point-in-time | Daily, ongoing |
| Detects & diffs vendor document changes | No | Yes — AI-summarized |
| Severity classification of changes | No | Major / moderate / minor |
| Vendor-change version history | No | Full, timestamped |
| Price tier | Enterprise GRC | From $49/mo |
The clean division: Vanta proves your controls work. Thorgate proves you're watching your vendors. One doesn't replace the other, and the vendor-monitoring evidence Thorgate produces attaches directly to the vendor section of a Vanta-run audit.
If you don't have a GRC platform yet
Thorgate alone won't get you through SOC 2 — it doesn't manage your own controls, evidence, or the audit itself. If you have no GRC tooling, you need something like Vanta or Drata for the program, and Thorgate for the vendor-document-monitoring layer on top. They're bought for different reasons and coexist cleanly.
