TLS VERSIONS END OF LIFE FREE
If you’re not sure which protocols your site supports, you can use our free SSL Server Test. Check If Your Site Supports SSL and TLS 1.0 Protocols On June 30, 2018, the PCI Data Security Standard (DSS) required that all websites needed to be on TLS 1.1 or higher in order to comply. PCI Compliance was another driving factor. Various vulnerabilities over the past few years (e.g., BEAST, POODLE, DROWN…we love a good acronym, don’t we?) have had industry experts recommending disabling all versions of SSL and TLS 1.0 for a while now.

"Apple said: 'Complete support will be removed from Safari in updates to Apple iOS and macOS beginning in March 2020.' Google has said it will remove support for TLS 1.0 and 1.1 in Chrome 81 (expected on March 17). Just another reason to make the switch to TLS 1.2 or 1.3, if you haven't already. You might have also seen the recent news that the browsers are officially removing support for TLS versions 1.0 and 1.1. This can leave your encrypted connections (whether between a site visitor and your web server, machine to machine, etc.) open to man-in-the-middle and other types of attacks. Continuing to support old versions of the protocols can leave you vulnerable to downgrade attacks, where hackers force connections to your server to use older versions of the protocols that have known exploits. We are currently on TLS 1.3, which was approved by the IETF (Internet Engineering Task Force) in March of 2018.Īs a best practice, you should configure your servers to support the latest protocol versions to ensure you are using only the strongest algorithms and ciphers, but equally as important is to disable the older versions. Since SSL’s first iteration back in 1995, new versions of each protocol have been released to address vulnerabilities and support the strongest and most secure cipher suites and algorithms.
