DigiCert ONE is available to customers from global regions including European, Australia, India, Japan, and the United States.[3]

DigiCert certificates can be ordered and administered through CertCentral Europe, which is hosted in European data centers to address data residency and sovereignty requirements. DigiCert signs all SSL certificates using the SHA-256 Algorithm. DigiCert assigns an alphanumeric serial number to each SSL certificate it issues. DigiCert offers identity-validated S/MIME for encryption, signing, and phishing protection. DigiCert describes protecting code signing for software releases.[2][3][4]

Verified Mark Certificates (VMCs) from DigiCert enable organizations to display their registered trademark logo in supported email clients. The BIMI standard requires organizations to have a logo that is a registered trademark so that they can be issued a VMC. DigiCert validates an organization's legal existence and confirms its control over the domain associated with the VMC request using Extended Validation (EV) standards. For a VMC, DigiCert performs additional validation beyond the standard Extended Validation (EV) certificate process. DigiCert validates that the SVG logo complies with BIMI requirements and exactly matches the registered trademark. The individual requesting a VMC must be verified as an authorized representative of the organization. Once approved, DigiCert issues the Verified Mark Certificate.[5][6]

DigiCert X9 PKI is a dedicated public key infrastructure designed to provide interoperability and flexibility for non-web browsers. DigiCert X9 PKI operations are governed by an ASC X9 Policy Committee and undergo an annual independent WebTrust audit. X9 PKI was born from the financial services industry’s need for a dedicated, interoperable trust framework. The X9 PKI is intended for non-browser TLS authentication scenarios. Its main use case at the outset is mutual TLS (mTLS) among financial institutions and between them and their partners and customers. Organizations with existing PKI systems can cross-certify with the X9 PKI root. DTCC will require X9 PKI certificates for securing connections to IBM MQ, Connect:Direct, and FTPS.
