About the URL Safety Analyser

The URL Safety Analyser analyses a URL for phishing indicators — lookalike domains, punycode, suspicious TLDs, redirects and obfuscation. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Checking a link in a suspicious email before clicking.
  • Spotting a homograph attack using lookalike characters.
  • Teaching someone what phishing URLs look like.

Details

Checks performedPunycode and mixed-script detection, brand lookalike matching, excessive subdomain depth, IP-address hosts, credentials in the URL, high-risk TLDs, URL shorteners, encoded characters, and suspicious keyword patterns
This analyses the URL text only. It does not visit the page or check any threat database, so a clean result is not a guarantee of safety. When in doubt, type the organisation's address yourself rather than clicking.
