How TrustEngine is built

TrustEngine sits at the core. TrustScore and TrustGraph are built on it.

TrustEngine

Purpose-built AI models, trained on scam signals and run on our own private infrastructure.

TrustScore

TrustEngine produces a TrustScore from 0 to 100 for every Singapore business entity, from authentication, reputation, branding and digital footprint signals.

TrustGraph

TrustGraph connects every scored entity and the links between them, so the networks that scams hide behind become visible.

How it works

  1. 1

    Ingest.

    Public registry data, community scam reports, lookups and verifications flow into TrustEngine.

  2. 2

    Score.

    TrustEngine produces a TrustScore for each entity and updates it when something new comes in.

  3. 3

    Connect.

    TrustGraph links scored entities, so connected risk shows up early.

  4. 4

    Act.

    The public sees a TrustScore on Scam.SG. Businesses earn Verified standing. Findings that need action are escalated for review and routed to the relevant parties.

Who we work with

Agencies, banks and platforms.

License TrustEngine for investigations, continuous monitoring and takedown support, with access to TrustGraph.

For institutions

Why this matters now

Singapore lost S$913.1 million to scams in 2025, across 37,308 reported scam cases. Fake businesses are built to look as credible as real ones, and legitimate businesses need a clear way to stand apart.

Since December 2024, the Shared Responsibility Framework has set out duties for financial institutions and telcos to protect consumers from phishing scams, and how losses are shared when those duties are not met.

Built to be accountable

Automated analysis, human decisions.

TrustEngine scores and flags. People review disputes and escalations before any action is taken.

A TrustScore is a signal, not a verdict.

It is a data-aggregation metric, not a regulatory determination or a certification. A lower score means fewer trust signals are visible, not that a business is a scam.

Private company, public interest.

TrustScore.SG is operated by OnScam (SG) Pte. Ltd. We are not a government agency or regulator.

Personal data handled under the PDPA.

We handle personal data in accordance with Singapore's Personal Data Protection Act.
