From where does the ProxySG obtain the client certificate during transaction processing when required?

The ProxySG obtains the client certificate from a store on the ProxySG where client certificates are uploaded. This is essential in transaction processing, particularly for features such as SSL interception and authentication where the ProxySG needs to verify the identity of the client.

When a client attempts to establish a secure connection, the ProxySG references the stored client certificates to authenticate and ensure that the client has the necessary permissions to access the requested resources. This method centralizes certificate management within the ProxySG, allowing for more efficient handling of user authentication across a controlled environment.

In contrast, while remote authentication servers and directory services can play roles in managing user identities and access rights, they are not the direct source of the certificates used for this specific operational need. The client itself may have a certificate, but it is the ProxySG's responsibility to access the appropriate certificate from its own store during the transaction process.
