We have an application team which is connecting to Pega from a dotnet script and they have configured ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
We want to make sure it matches the protocol we have. Can you confirm?

All modern version of Pega support TLS1.2. External components like loadbalancers that do TLS offloading could however have different configurations, but most support TLS1.2 these days.
Please never use the unsecure SSL3 and only configure the highest protocol, meaning only select SecurityProtocolType.Tls12.
Since you're working on securing your connections, let me recommend to also investigate the cypher suits that you're supporting over TLS and also finetune security for outbound connectivity. (In your Connect- rules look for Lowest allowable SSL/TLS version)
