The short answer is, yes. DigiCert offers solutions for both public and private PKI, along with a platform and RESTful API, which allow you to automate certificate management and customize PKI workflows.
You may have only worked with a commercial CA to purchase public SSL certificates. With this as your only reference point, you might assume private certificates have similar costs as public certificates—this isn’t the case. Issuing a private digital certificate with DigiCert is a fraction of the cost of a public certificate.
Security engineers and administrators sometimes mistakenly think a hosted private PKI will limit them to certain certificate profiles. They think they’ll only have access to certificate profiles that are approved by the CA/Browser Forum. However, DigiCert can provide you with any certificate profile you need. These certificate profiles don’t have to be SSL/TLS certificate profiles—they don’t even have to be X.509.
