Systems and methods are provided for deploying keys in connection with proxy resolution. One example computer-implemented method includes distributing, by a service core computing device, a root certificate signed by a certificate authority and an intermediate certificate, which is signed by a root private key associated with the root certificate, and receiving, from a participant, a signing request for a participant certificate including a participant public key. The method also includes assessing, by the service core computing device, the signing request for the participant certificate and signing, by the service core computing device, the participant certificate with an intermediate public key included in the intermediate certificate. The method then includes disseminating the signed participant certificate to the participant and another participant, whereby the participants on the participant certificate based on the participant certificate being signed by the intermediate public key.
