TLS 1.2 Supported OS and Browsers

TLS 1.2 Supported OS and Browsers

TLS 1.2 Supported OS and Browsers

Most of the Website will no longer supports older versions of TLS protocols which is TLS 1.0 and TLS 1.1. This will be required in order to maintain the highest security standards of website.

This means most of the website will supports only TLS 1.2 or higher.

What is TLS?

TLS which is full form of Transport Layer Security, a protocol used by website to communicate between client and server with data integrity and privacy.

Available TLS versions

  1. TLS 1.0
  2. TLS 1.1
  3. TLS 1.2
  4. TLS 1.3 (Latest)

Note: Most of the website does not support TLS 1.3 yet. But move to TLS 1.3 will be good step to make.

Here, the problem we face while disable TLS 1.0 and TLS 1.1 support and only allow TLS 1.2 and above protocols.

  1. Older version of Operating Systems does not support TLS 1.2
  2. Older version of Browsers does not support TLS 1.2.

So, I have summarized the TLS 1.2 supported OS and Browsers in below table.
