How well is this website protected?

Enter a domain. sitecheck looks at its HTTPS setup, security headers and cookies the way a browser would, and grades it from A to F.

What gets checked

Connection
A valid certificate, a modern TLS version, and a redirect from http:// to https:// that browsers are told to remember.
Content protection
Headers that stop injected scripts, clickjacking and file-type tricks.
Privacy and permissions
How much of each URL leaks to other sites, and whether camera, microphone and location are locked down.
What the server reveals
Software names and versions an attacker would otherwise have to look up.
Cookies
Secure, HttpOnly and SameSite on every cookie the site sets.

90 points or more is an A, 80 a B, 70 a C, 60 a D. Anything lower is an F. A site that can't be reached at all gets an F as well.

Sites this server keeps an eye on

Re-checked every few hours. A drop in grade, an outage or a certificate close to expiry sends an alert.
