Protocols such as SSLv2 and SSLv3 are no longer considered secure. In addition, TLS 1.0 and TLS 1.1 have also been deactivated and TLS 1.3 and TLS 1.2 are activated by default.

Note: When you upgrade from VMware Aria Operations 7.5 and above to 8.4 (and above), the user modifications to TLS settings are preserved. When you upgrade your VMware Aria Operations instance from 7.5 to 8.4 (and above), both TLS 1.0 and TLS 1.1 are deactivated on all the VMware Aria Operations nodes. TLS 1.3 and TLS 1.2 are the only protocols that are supported by default.
