[Proofpoint On Demand] Investigate adding forward proxy support #11581

Open cpascale43 opened 3 weeks ago

cpascale43 commented 3 weeks ago

Currently, the Proofpoint On Demand integration doesn't support proxying websocket connections. This is necessary to prevent the integration from being blocked by customer firewalls.

Investigation is needed as to what changes are needed to support forward proxying.

See: https://github.com/elastic/enhancements/issues/23003

@cpascale43, I'm looking into this. Forward proxy with (optional) TLS support will need to be implemented at the input level.
