Update Your Existing Site's TLS Settings

Overview 

You can use this document to update your existing site's Transport Layer Security (TLS) settings. 

TLS is a widely adopted cryptographic protocol that provides communications security over networks and is widely used for internet communications and online transactions.

TLS is used for SSL certificates, HTTPS, email, and voice-over-IP communications.

TLS replaced Secure Sockets Layer (SSL). Even though TLS 1.3 is the latest version, StackPath recognizes TLS 1.2 as the current, more stable version of TLS. 

Update your existing site's TLS settings

By default, sites created after July 2019 will use TLS 1.2. 

When you update your site's TLS settings, only clients who support the selected TLS version or above will be able to access your application or website. Clients who use a lower version of TLS will not be able to connect.

1. In the StackPath Control Portal, in the left-side navigation menu, click Sites. 
2. Locate and select the desired site. This action will refresh the portal. 
3. In the left-side navigation menu, click EdgeSSL. 
4. Under Options, next to Minimum TLS Version, select the desired minimum TLS version required for access.
