Free trust check
Is your website ready
for the quantum era?
Enter a URL and, in about 30 seconds, see HTTPS, security headers and whether your PHP or CMS version is visible from outside. No sign-up.
We only look at what anyone can see from outside (TLS, certificates, security headers and so on). No intrusive testing, and the URL you enter is not stored.
This is the lite edition (HTTPS, security headers, PHP / CMS exposure and more). Post-quantum key exchange and TLS details are planned for the spot assessment (¥4,980, under consideration).
