Check TLS Version

About TLS Protocol Testing

Transport Layer Security (TLS) is a technical term for securing communication between two computers.

When we say TLS, we mean the existence of HTTPS on your website. HTTPS, like any other standard in the world, keeps evolving (with more advanced encryption), and as a result, new versions are released.

And that is what this TLS tool does: it tells you which versions of TLS your website supports and which encryption algorithms are being used.

Why should you care?

Simply having HTTPS enabled is not enough.

Computer security is a moving target, and things considered infallible a decade ago have now been abandoned.

This TLS test can tell you how strong your HTTPS security is. If you don’t have the latest version, you must (we aren't kidding!) get your hosting provider or CDN to upgrade it.
