TLS v1.2 is still regarded as a secure protocol and many clients (including Tableau Desktop) do not yet support TLS v1.3. We recommend that you allow external clients to connect to Tableau Server with TLS v1.3 and TLS v1.2. As a result, Tableau Server does not allow external clients to use SSL v2 or SSL v3 protocols to connect. In fact, older versions of SSL (SSL v2 and SSL v3) are no longer considered to be adequately secure communication standards. Transport layer security (TLS) is an improved version of SSL. External clients, such as browsers, Tableau Desktop, Tableau Mobile connect to Tableau using TLS over HTTPS. Tableau Server uses TLS to authenticate and encrypt many connections between components and with external clients.
Configure Tableau Server with a valid, trusted certificate (not a self-signed certificate) so that Tableau Desktop, mobile devices, and web clients can connect to the server over a secured connection. Secure Sockets Layer (SSL/TLS) is essential for helping to protect the security of communications with Tableau Server. Configure SSL/TLS with a valid, trusted certificate To get the latest version or maintenance release of Tableau Server, visit the Customer Portal (Link opens in a new window) page.

(Information regarding known security vulnerabilities can be found on the Tableau Security Bulletins page and the Salesforce Security Advisories (Link opens in a new window) page.) We recommend that you review maintenance release notifications to determine whether you should install them. Additionally, Tableau periodically publishes maintenance releases of Tableau Server that include fixes for known security vulnerabilities. We recommend that you always run the latest version of Tableau Server.
