    Important: As of January 18th, 2019, Tableau Online will only support encrypted connections over TLS 1.2

    John Blackie

      Tableau Online will be removing support for TLS 1.0/1.1 in favor of the more secure TLS 1.2.

       

      What do I need to do?

      Customers using a web browser to connect to Tableau Online will need to ensure they are using a version that supports TLS 1.2. We've provided links to help you determine whether you will be impacted in the Additional Resource section below.

      Customers using a 3rd-party tool or custom software to connect to Tableau Online should reach out to the developer to ensure they support TLS 1.2

       

      What is TLS?

      TLS stands for "Transport Layer Security." The TLS protocol provides secure transport of information between two applications. It is the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network.

       

      Why is Tableau doing this?

      Earlier versions of TLS have been found to have vulnerabilities that may allow an attacker to expose sensitive information passed over this connection. In addition, multiple security standards organizations including NIST and PCI have declared that TLS 1.0/1.1 no longer provides sufficient data protection.

       

      Who is affected?

      Customers attempting to connect to Tableau Online using web browsers or other software using TLS 1.0 or TLS 1.1.

       

      Deadline to make the change:

      In order to make sure your ability to connect to Tableau Online isn't interrupted, we suggest that you complete the steps above prior to January 18, 2019.
