What You Need to Know
At Prometric, we rely on the Transport Layer Security (TLS) which is a set of rules (called a protocol) that helps ensure privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS ensures that no unwanted third party may eavesdrop or tamper with any message. Beginning
April 1, Prometric will only support TLS 1.1/1.2/SHA-2. 
 
Important Tips
·         If you are experiencing issues connecting, it is important to confirm you are connecting properly with the TLS 1.1/1.2/SHA-2 protocol.
·         If you use a non-supported operating system or browser (such as Windows XP/Vista or anything below IE 9), you may be trying to connect through a lower protocol that could put your data at greater risk. Click here to test your browser.
·         If you still have questions on how to upgrade, just submit your question(s) to our technology experts at browsersecurityinquiries@prometric.com
What You Need to Do                                                                       
·         If you experience an error when opening a link, enable TLS 1.1 or 1.2 in your browser. Additionally, we recommend that you disable TLS 1.0 in your browser.
·         If your browser does not support the newer TLS 1.1 or 1.2 versions, replace or upgrade your browser with a more recent or supported version.
