Try the benefits of TLS 1.3 for yourself!

Why don’t I have a perfect score?

There are 3 possible scenarios based on your input:

  1. Your server doesn’t support TLS 1.3
  2. Your CDN doesn’t support TLS 1.3
  3. Input doesn’t align with your testing intentions, e.g. checking your origin server instead of CDN.

TLS and SSL - which one should you use?

Your SSL/TLS certificates are used to establish HTTPS connections that can run on all SSL and TLS protocol versions. IETF has already deprecated all SSL protocols, TLS 1.0, and TLS 1.1 - you'll see them marked red if enabled. We recommend using the latest version of TLS to maintain the best performance and security.

If you're using CDN77, it handles all of this for you - deprecates the old versions and enables TLS 1.3, which is the most secure one.

What are the benefits of TLS 1.3?

TLS 1.3 encryption protocol enhances the HTTPS performance and security for all users and provides many improvements in comparison with TLS 1.2 and older. The most prominent one is reduced latency by making the TLS handshake shorter and more efficient before any secure session is established.
