Announcing a Test Window Deprecating Cipher Suites Using SHA-1

We are aware that some accounts are still using a cipher suite that uses the SHA-1 algorithm for secure communication with NetSuite. Secure communication with NetSuite is subject to the Transport Layer Security (TLS) protocol, and TLS v1.2 is required. The cipher suites using the SHA1 algorithm are no longer considered secure. You should be using the higher-level cipher suites that were introduced with TLS 1.2. These higher-level cipher suites are supported for use with NetSuite.

See Supported TLS Protocol and Cipher Suites, SuiteAnswers ID 84138, for more information.

To ensure you are ready for the final deprecation of cipher suites that are using SHA-1, we are scheduling a 24-hour test window on
