A system for provisioning computerized devices of a plurality of tenants is provided. The system includes a security credential management system (SCMS) host connected to the devices and that is operable to receive provisioning requests from respective ones of the devices needing certificates, each provisioning request indicating a tenant identifier uniquely identifying a tenant, at least one registration authority that is communicatively connected to the SCMS host and transmits the provisioning requests to SCMS backend components based on the tenant identifier of each provisioning request. The SCMS backend components includes a plurality of enrollment certificate authorities operable to generate the enrollment certificates in response to the provisioning requests, each provisioning request being transmitted to one of the plurality of enrollment certificate authorities based on the tenant identifier of each provisioning request, and a pseudonym certificate authority operable to generate pseudonym certificates in response to provisioning requests for pseudonym certificates.
