Trellix supports two cipher-level arguments; compliant-security and high-security. On initiation of a connection, the high-security ciphers are offered first, which ensures that if supported, a high-security cipher will be negotiated in practice. If high-security isn’t supported, a compliant-security cipher will be negotiated.
Note
Compliant-security ciphers and high-security ciphers are approved and certified by The National Institute of Standards and Technology (NIST) and National Information Assurance Partnership (NIAP).
For supported cipher suites over a secured network, see the following tables.
