How TrustSeal measures trust: the methodology, standards, framework, and the signals behind every score.
Trust methodology
TrustSeal converts verifiable evidence into an explainable trust score (0–100) and a trust band. We start from proven domain ownership, then evaluate independent signal categories and combine their sub-scores under published weights. Every score is explainable: the public seal page shows the per-category breakdown and the per-signal evidence behind it.
Verification standards
- Ownership is proven cryptographically via a unique per-claim DNS TXT token — not self-assertion.
- The first account to verify a domain owns it within TrustSeal; tokens expire.
- Verdicts are server-authoritative and re-checked over time; clients cannot alter their own score or band.
- Clean verdicts are cached briefly and risky verdicts longer, so a freshly-weaponized domain cannot hide behind a stale good score.
Trust framework (the five bands)
- Verified — ownership confirmed, signals strong.
- Established — solid, consistent reputation history.
- Limited — verified but with thin or new signals.
- Caution — anomalies detected; review before transacting.
- Risk — blocklist or impersonation signals; high risk.
Signal library
Signals are grouped into categories, each contributing a sub-score:
- DNS — resolution, mail (MX), and email-auth records.
- SSL/TLS — certificate validity, validation level, and age.
- Reputation — blocklist providers and intelligence-graph signals.
- WHOIS — domain age and registration data (where available).
- Impersonation — look-alike / brand-impersonation patterns.
- Legitimacy & web — site presence and consistency signals.
Confidence & coverage
Each verdict carries a confidence level reflecting how much signal coverage was available. A partial verdict (some categories not yet assessed) is labelled as such — TrustSeal never implies more certainty than the evidence supports.
Programmatic access
The methodology is queryable: the public Trust API (GET /api/trust/{domain}) returns the status, trust level, score, confidence, full breakdown, and signals as JSON. See the Documentation for details.
