Browser support ending for TLS 1.0 and 1.1

In 2020, the four major browsers are ending support for Transport Layer Security (TLS) 1.0 and 1.1.

This change doesn't affect your DigiCert certificates. Your certificates will continue to work as they always have.

What you need to know

This change affects browser-dependent services and applications relying on TLS 1.0 or 1.1. Once browser support for TLS 1.0 or 1.1 ends, these out-of-date systems will be unable to make HTTPS connections.

What you need to do

If you are affected by this change, plan to enable or upgrade to TLS 1.2 or TLS 1.3 now. Give yourself lead time to deal with any problems. Before you start, make sure to identify all systems that might use TLS 1.0 or 1.1.

Remember to check web servers like Apache or Microsoft IIS, .NET Framework, server monitoring agents, and other commerce applications that might use it.
