Is this site sus?
One click. Traffic light. Done.

Cloak Check audits the page you're on in under a second — HTTPS, scam signals, dodgy forms, brand impersonation, hidden click traps — and gives you a plain-English verdict in three colours. Nothing leaves your browser.

The verdict

Three colours. No jargon.

Green means the page looks safe. Amber means be careful — something about the connection or the page deserves a second look. Red means serious issues: stop and close the tab. Every verdict comes with the reasons in plain English, so you learn what to look for next time.

Under the hood

What it checks

One click runs a bundle of checks on the page you're looking at — the same things a security-minded person would look for by hand, done in under a second.

Connection security
Is the page properly encrypted (HTTPS), or is anything on it loading insecurely?
Scam signals
Patterns that show up in scam pages — urgency bait, fake countdowns, too-good-to-be-true hooks.
Dodgy forms
Forms that ask for logins or payment details without the protections a legitimate site would have.
Brand impersonation
Pages dressed up as a brand they don't belong to — a classic phishing move.
Hidden click traps
Invisible overlays and disguised buttons designed to make you click something you didn't mean to.
Site headers
The security settings a well-run site declares — missing ones are a sign of a carelessly built page.

Private by design

Cloak Check runs entirely inside your browser. It doesn't send the pages you visit anywhere, doesn't phone home, and doesn't need an account. There's nothing to configure and nothing to worry about — which also makes it easy to recommend to students and parents.

In the classroom

A live demo that lands

Run Cloak Check on a real page in front of a class and the abstract idea of "checking whether a site is safe" becomes a one-click habit students can copy. It pairs naturally with the free classroom activities — especially Would You Click? — and it's an easy, concrete recommendation for parents' evenings: free, nothing to set up, nothing shared.
