Fake codes hide in ordinary places

Tap a code to see where it really leads. Not every code is a trap, which is exactly why you cannot tell by looking.

Three steps, a few seconds

  1. Scan or paste

    Use the camera, pick a photo from your gallery, or paste a link.

  2. QuishGuard checks the link

    The link is checked with VirusTotal, our own blacklist and a set of URL risk checks.

  3. You decide

    You get Safe, Suspicious or Malicious, with a risk score and the reasons. Dangerous links are blocked.

Clear answers instead of security jargon

Every result explains itself, and your protections stay on until you choose otherwise.

See the real domain

The true domain is shown in bold, so a fake address stands out from the real one.

Reasons you can read

Each result lists what raised or lowered the score, such as how many security engines flagged it.

Your scan history

Search and filter everything you have checked, grouped by day.
