Online Banking Browser Security Upgrade

Transport Layer Security (TLS) is a protocol that ensures that a connection to a remote endpoint is securely encrypted in order to provide privacy and data integrity. Fiserv web applications and application programming interface (API) connections use TLS as a key component of their security. TLS 1.2 is the most current version and is considered to be the most secure. TLS 1.0 and 1.1 are earlier, now less secure versions. The predecessor to TLS, Secure Sockets Layer (SSL), has been disabled in Fiserv Bank Solutions systems.

 

Fiserv Bank Solutions has enabled TLS 1.2 for most internal and all external web applications and API connections. Most user connections to Fiserv services currently are already using TLS 1.2. Browsers and operating systems that support TLS 1.2 will typically utilize it by default, preferring TLS 1.2 over older, less secure encryption protocols. 

 

Fiserv is disabling the less secure TLS 1.0 and 1.1 encryption protocols across all applicable Fiserv Bank solutions services. After this change, users accessing Fiserv Bank Solutions systems must use operating systems and browser versions that support TLS 1.2 and ensure that TLS 1.2 is enabled.
