This is a feature request to add support for the more secure ICAPS protocol (ICAP over TLS) in a future version of the API Gateway. Right now the Gateway only supports icap.
Justification: Our security teams are requesting we integrate with virus scanners using secure ICAP.
This needed to be open as an idea which I have done. Please make sure to vote on the idea.
