The One Identity Safeguard for Privileged Sessions Administration Guide has a chapter entitled "Supported protocols and client applications". This details the following (from the 6.1 Administration guide):
"One Identity Safeguard for Privileged Sessions (SPS) supports the following protocols and clients. As a general rule, client applications not specifically tested, but conforming to the relevant protocol standards, should work with SPS. One Identity supports the listed client and server applications only on a best-effort basis after their vendor or manufacturer declares end-of-support or extended (or any other non-standard support) period for them. Best-effort basis means that without the vendor support we only can fix issues with our existing knowledge in the problematic area, and can implement straightforward fixes only."
The Administration Guide then has sections detailing the supported protocols and clients.
