Detailed assessments

How the mark is built

Transparent and reproducible — the same method any analyst could re-run from public sources.

Five dimensions

Security · Personal data · IP (no training) · Legal / AI Act / bias · Output quality.

Basis ladder

Certified (independent audit → residual 0–1) · Assessed (reviewable terms → 1–2) · Declared (self-attestation → floor of 2).

Residual risk 0–4

0 None · 1 Low · 2 Moderate · 3 High · 4 Severe. The governing line is the highest residual across the five.

Class Mark

Residual 0–1 → A · 2 → B (in class, qualified) · 3 → C (conditional) · 4 → D (not in class).

Trust Score (300–850)

850 − Σ penalty. Penalty = BASE[residual] (0/18/50/105/175) + ADJUST[basis] (Cert 0 / Assessed +6 / Declared +12).

Ranking

By governing residual, then Trust Score, then number of Certified dimensions.

Scope & caveats. Seeded from public vendor trust centres, DPAs, model/system cards, certificate registries and reputable press — no contributory or confidential data. This is a procurement-triage signal, not a compliance determination, endorsement, or legal advice. A vendor may claim and verify its profile to upgrade Declared lines to Assessed or Certified.
