The internet’s side-eye.
A second opinion before you get scammed.
Every scam has a tell. Cautellus catches it across links, texts, screenshots, phone calls, and webpages — before you click, reply, or pay.
Security tools were built for IT teams. Cautellus is built for everyone else — fast scam checks, plain-English risk scores, Chrome page scanning, and shareable Scam Energy results.
No signup for first scan. We don’t store your input. Images are processed in real time and discarded.
With the Chrome extension, scan suspicious pages, links, and messages without leaving your browser.

Cautellus runs 7 layers of detection — domain age, sender, language, image forensics, pattern matching, and more.
