Install and Configure Omnissa Credential Escrow Gateway
In as SaaS world there might be some certificates you may not want to store / be able to unencrypt the Private Key in a SaaS-Service. As Client Authentication Certs can today can use SCEP there are use cases where this does not work like S/MIME. Therefore there is for Omnissa Workspace ONE UEM the Credential Escrow Gateway that stores the Certs and sends them encrypted to UEM only for consumption for the Devices. As the Certs are encrypted by a Cert on the Device, UEM itself can not unencrypt the Payload on UEM , only the Device or SDK Level can unencrypted the Certificate.
