How Scanning Works

The checks that run behind every scan and the data sources they use.

How Scanning Works

When you submit a URL, Alertoscan runs a multi-stage pipeline. Every stage is independent, so a slow or failing source never blocks the others.

The scan pipeline

  1. Reachability. Resolve DNS and confirm the site responds, with fallback to public resolvers when needed.
  2. Page capture. Render the page in a real browser, take a screenshot and capture the DOM, headers and network requests.
  3. Reputation checks. Query antivirus engines, Google Safe Browsing, Cloudflare phishing detection and community blocklists.
  4. Regulatory check. Match the domain against warning lists from financial regulators worldwide.
  5. Infrastructure. Collect WHOIS, SSL certificate, hosting, ASN and the technology stack.
  6. Scoring & summary. Combine every signal into the Trust Score and generate a plain-language summary.

Why results can change

A domain's score is a snapshot. Sites get re-listed, certificates expire and new warnings get published. Alertoscan refreshes data on a 10-day cycle and on demand, so a domain that was clean last month may be flagged today.
