The Sauce Labs team is committed to providing the most secure testing experience for you and your teams. To help with that, we are making a number of updates that bring us more in line with industry standards.

To help with this change, we  have made the decision to begin the End of Life (EOL) process for the following:


  • All versions of Sauce Connect Proxy prior to 4.6.x

  • TLS protocol versions 1.0 and 1.1


This EOL will be completed on October 5, 2020.

Sauce Connect Proxy

In line with security best practices, Sauce Connect Proxy will only support certificates signed by a Public Certificate Authority going forward. All Sauce Connect Proxy versions <4.6 supporting Private Certificates will be deprecated as of October 5, 2020.

If you are currently running any version of Sauce Connect Proxy previous to 4.6.0 you will need to update prior to October 5, 2020. Download and instal the latest version of Sauce Connect Proxy here.

If applicable, please also ensure you are using the latest version of the Sauce Labs Jenkins plugin.

TLS Protocol

In keeping with industry standards, Sauce Labs will also be fully deprecating support for TLS v1.0 and TLS v1.1 protocol versions.  This will affect all https traffic connecting to Sauce Labs, including:


  • Test runners

  • API clients

  • Web browsers that access the Sauce Labs UI


As of July 2020, the great majority of https traffic to the Sauce Labs service uses TLS 1.2 (99.9% or higher).  Most customers will not need to take any advanced action. Nonetheless, we encourage our users to verify which version they are currently using before the EOL date of October 5, 2020.
