SCEPman is a slim and resource-friendly solution to issue and validate certificates using Simple Certificate Enrollment Protocol (SCEP). It is an Azure Web App providing the SCEP protocol and works directly with the Microsoft Graph and Intune API. SCEPman uses an Azure Key Vault based Root CA and certificate creation. By default, no other component is involved, neither a database nor any other stateful storage except the Azure Key Vault itself. That said, SCEPman will not need any backup procedures or other operation level tasks. Only an Azure subscription is necessary to deploy it.
SCEPman is a service that gets deployed into your Azure tenant, giving you full control on how and where SCEPman processes and stores data. No data leaves your tenant and there is no need to grant external vendor permissions in your tenant.
SCEP flow with Microsoft Intune
The following documentation will show you a straightforward way to deploy certificates to modern cloud managed clients. Without any on-premises PKI your users and devices will be able to get certificates.
SCEPman vs. Legacy PKI
If you are interested in learning more about the effort involved in installing and operating a legacy/on-premises PKI such as the Certificate Connector for Intune / Active Directory Certificate Services (ADCS) in comparison to SCEPman, please refer to below article.
