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. 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.
Our Institution’s processors will require that all users be able to support the TLS 1.2 protocol and ensure that TLS 1.2 is enabled.
Below is a basic TLS 1.2 compatibility chart.
