What is PKI as a Service?
Public Key Infrastructure (PKI) as a service, or PKI as-a-Service (PKIaaS) delivers managed PKI services via a cloud platform to provide streamlined and automated certificate lifecycle management. PKIaaS can be hosted from a PKI service provider such as DigiCert, a large enterprise’s private cloud, or a public cloud such as Microsoft Azure. By leveraging PKIaaS, organizations can eliminate the burden of managing a data center and hardware security (HSM) for key storage.
PKIaaS is one of many deployment models for PKI. There are also other options for organizations with complex requirements. DigiCert ONE, a PKI solution with flexible deployment options, provides on-premises, in-country or in-region deployment. With a flexible deployment model, organizations can select the option that best fits their requirements.
