Where ThirdProof Fits
There are three ways to answer “can we use this vendor?” — do it manually, run an evidence-first assessment, or implement an enterprise TPRM platform. Here is what each one is good at, including the parts ThirdProof deliberately doesn’t do.
| Capability / Need | Manual / Questionnaire FirstSpreadsheets + email | ThirdProofEvidence-first assessment | Enterprise TPRMFull program platform |
|---|---|---|---|
| Start evaluating immediately | Limited — every review starts as manual research | Core strength — enter a domain and the assessment starts | Depends on implementation |
| Vendor response needed to begin | Often — the questionnaire is the first step | No — the investigation runs on independent sources | Varies by platform |
| Independent evidence gathered first | Manual, one analyst at a time | Core workflow — 27 sources queried in parallel | Varies by platform |
| Source-cited assessment | Manual to assemble and format | Yes — findings cite the source they came from | Varies by platform |
| Targeted vendor follow-up | Manual — you write the follow-up yourself | Yes — unanswered questions are grouped into a drafted follow-up | Yes |
| Full vendor lifecycle management | No | No — intentionally out of scope | Yes |
| Complex workflows and approvals | No | No — one documented reviewer decision per assessment | Yes |
| Issue management | Manual tracking | Limited — conditional approvals with tracked conditions and evidence | Typically yes |
| Implementation overhead | Low, but every review is manual | Minimal — no setup or vendor inventory required first | Higher — an implementation project |
| Best fit | Occasional, one-off reviews | Lean teams that need a defensible assessment now | Mature TPRM programs |
Enterprise TPRM platforms differ widely — those columns say “varies” rather than guessing on a specific product’s behalf.
The actual problem in front of you is “I need to evaluate this vendor and document my decision.” Not “I need to stand up a third-party risk program.”
- ›Someone wants to use a vendor and procurement is waiting on you
- ›You need documented due diligence for a SOC 2 or ISO 27001 audit
- ›This is your first formal vendor-risk process
- ›A questionnaire has been out for weeks with no response
- ›You own compliance alongside four other jobs
Your job is running a program, not evaluating a vendor. ThirdProof is not built for these, and saying so is cheaper for both of us than an implementation that disappoints.
- ›Hundreds or thousands of vendors under continuous management
- ›Contract, renewal, and offboarding lifecycle tracking
- ›Multi-stage approval chains across several stakeholder teams
- ›Formal issue management with owners, SLAs, and remediation tracking
- ›Procurement orchestration wired into your ERP or ticketing system
Traditional diligence asks the vendor what is true
before checking what is already knowable.
ThirdProof reverses that order. Independent evidence first, so the questions you send the vendor are the ones that genuinely couldn’t be answered any other way.
- 1Send the questionnaire
- 2Wait
- 3Chase
- 4Receive self-reported answers
- 5Verify them anyway
- 1Enter the vendor's domain
- 2Independent evidence collected
- 3Assessment documents what was found
- 4Supported answers pre-filled
- 5Targeted follow-up on what's left
ThirdProof does the investigation. You make the decision — proceed, investigate further, mitigate, or ask the vendor for more. The assessment is evidence for that call, not a substitute for it.
Longer comparisons
More detail on specific alternatives and where each one makes sense.
ThirdProof vs. Spreadsheets
A spreadsheet tracks vendor names. It doesn't investigate them or document why you decided what you decided.
What TPRM Software Costs
Published rate cards, quote-only platforms, and where a smaller plan does and does not fit.
Assessing Vendors Without a Compliance Team
How teams with no dedicated TPRM headcount run vendor due diligence and document it.
ThirdProof vs. Vanta
A broad compliance platform with vendor risk as one module, next to a tool that does vendor risk only.
ThirdProof vs. Drata
One module, or the whole platform — what buying just the vendor risk part looks like.
ThirdProof vs. UpGuard
Continuous attack-surface monitoring next to a deep, documented per-vendor investigation.
You already have a vendor in mind. Start there.
Run the assessment, read what came back, and decide whether this is the right shape for your team. No implementation to sit through first.
