Security Ratings & Vendor Risk Tools: An Objective Comparison (2026)
Compare · Security
Who this is for
Security and procurement teams assessing their own external posture, or a vendor’s, for third-party risk, cyber-insurance, or due diligence.
The distinct questions
| Question | What you need | Tools |
|---|---|---|
| How exposed are we / a vendor, from outside? | Outside-in security ratings | BitSightPaidVendor, SecurityScorecardPaidVendor, UpGuardPaidVendor |
| Is this open-source dependency well-run? | Automated hygiene checks | OpenSSF ScorecardFreeOpen-source (free) |
| What security posture does a vendor publish? | Certifications, trust docs | VantaPaidVendor, SafeBasePaidVendor, DrataPaidVendor trust centres, trustlists.orgFreeVendor (free directory) |
| Does the vendor have a disclosure route? | security.txt, advisory feed | manual / uriports |
| How do we answer a customer’s security (incl. AI) questionnaire? | Questionnaire automation | VantaPaidVendor, DrataPaidVendor, ConveyorPaidVendor, AutoRFPPaidVendor, ComplyJetPaidVendor |
Honest tool-by-tool
- BitSight / SecurityScorecard / UpGuard: the three outside-in ratings leaders. Scan internet-facing assets and score them. Enterprise-priced; ratings are a proxy, sometimes attribute assets wrongly — verify before acting. SecurityScorecard has moved toward real-time threat evidence (Driftnet acquisition).
- OpenSSF Scorecard (free): the honest baseline for open-source dependency hygiene — automated checks, live API, no cost. GitHub-only; a score isn’t a decision.
- Trust centres (Vanta/SafeBase/Drata/Conveyor): where vendors self-publish certs (SOC 2, ISO 27001). trustlists.org aggregates them free. Self-reported, so corroborate.
- CloudSEK BeVigil: for mobile app external exposure (leaked keys, etc.).
- Questionnaire automation (Vanta, Drata, Conveyor, AutoRFP, ComplyJet): draft answers from your own approved content. Vanta and Drata now bundle ISO 42001 (AI management) frameworks and AI-questionnaire features; ComplyJet targets early-stage startups at a flat ~$5k/yr (2026). The most common AI question is still “where is our data stored, and do you train on it?”, so answer that one clearly first.
How to choose
- Open-source hygiene: OpenSSF Scorecard, free, first.
- Vendor due diligence: check their trust centre; escalate to a ratings tool only for material contracts.
- Cyber-insurance / large TPRM programs: BitSight or SecurityScorecard, accepting the cost and the false-positive tax.
Bottom line
Mature, well funded and consolidated. Free tools (OpenSSF Scorecard, trust-centre directories) cover most teams’ needs; paid ratings earn their place in formal third-party-risk programmes and cyber-insurance.
