TLS 1.2 Security Protocol & Mercury Network

Browser Check

To determine if further action is needed, you can click here to visit a site that will show you if your browser uses the necessary protocols.

Once you've reached that page, check the Protocol Support and Cipher Suites sections. If they look like the examples below (with mostly green text indicating support for TLS 1.2), no further action is needed. However, if those sections indicate that TLS 1.2 is not supported, check the remaining tabs on this page for a solution specific to your browser.

3. Select Internet Options.

Earlier versions of Internet Explorer

Apple Safari

There are no options for enabling SSL protocols. If you are using Safari version 7 or greater, TLS 1.2 is automatically enabled. If you're using a previous version, please update your browser.

Other

There are many internet browsers available, ranging from device manufacturers (such as Samsung or LG) to operating system flavors (such as Linux Ubuntu). While we cannot provide instructions for enabling TLS 1.2 on each of them, as a general rule, if you update to the latest version of your browser, TLS 1.2 should be supported.

If you continue to experience problems or cannot update your current browser, we recommend installing one of the other browsers mentioned on this page (all of them are free) to take advantage of the latest security protocols and features.
