TrustSeal is a Trust Intelligence Platform that turns domain ownership and reputation signals into a verifiable trust score — with verification certificates, a public Trust API and business verification. Built by A Square Solutions.
TrustSeal is a Trust Intelligence Platform. It evaluates a website or business across ownership, security and reputation signals and turns them into a single, explainable trust score — so customers, partners and platforms can quickly tell who they are really dealing with online.
What TrustSeal does
TrustSeal brings five capabilities together in one platform:
- Domain verification — confirm that a domain is genuinely owned and controlled by who it claims, using DNS/TLS and ownership checks.
- Trust scores — an explainable score built from ownership, TLS/security, reputation and risk signals, so the rating is transparent rather than a black box.
- Verification certificates — shareable, tamper-evident proof of a domain’s verification status and score at a point in time.
- Trust API — a public API to query a domain’s trust status programmatically and embed it in your own apps, marketplaces or checkout flows.
- Business verification — extend verification beyond the domain to the business behind it, for higher-assurance trust.
How the trust score works
Rather than a single opaque number, TrustSeal evaluates a domain across several independent dimensions — ownership, TLS and security posture, reputation signals, and risk indicators — and combines them into one score with a clear breakdown of why. Because the score is explainable, businesses can see exactly what is helping or hurting their trust rating and act on it.
Who TrustSeal is for
- Businesses and online stores that want to prove legitimacy and reduce buyer hesitation.
- Marketplaces and platforms that need to verify the domains and sellers operating on them.
- Buyers and partners checking whether an unfamiliar website or business can be trusted before transacting.
