I would like to use an on-premise web service to fetch information. I want to limit the access to those services. My first idea was to limit at the firewall level but RunMyProcess run over Amazon (And it mean that I would need to open multiple ranges of IP adress). My second idea is to use our reverse proxy that can preauthenticate external servers with certificates.
The question is : if asked for a client certificate (during the TLS handshake), does your servers will send a certificate or your implementation of the client (the client that access the web services) does not support that feature?
Thank you!
