Answer


In an effort to ensure that merchant-secure communications to the CyberSource platform remain as secure as possible (both browser-based as well as server-to-server communications), CyberSource will eliminate support for certain older and less-secure forms of Transport Layer Security (TLS) communication and Cipher Suitesin the coming months. Refer the article, CyberSource Security Updates - Possible Production Impact - TLS 1.2, for the full list of CyberSource endpoints and up-to-date termination dates.

Below is the list of supported cipher suites with TLS v1.2 for each CyberSource API endpoint in both CAS (test) and Production environments:
