How they differ

CISO Tribune files both DigiCert and Keyfactor under Machine identity and PKI as their primary category, though DigiCert's filing also lists Post-quantum cryptography, DNS security, and Email authentication and DMARC. DigiCert sells CertCentral for ordering and administering its certificates, Private CA for internal use cases, and DigiCert X9 PKI for non-browser TLS authentication. It also sells AI Trust Manager, which assigns each AI agent an AI Agent Passport. DigiCert issues qualified certificates under eIDAS, PKIoverheid, and ZertES. Keyfactor sells Keyfactor Command for certificate lifecycle management, EJBCA Enterprise as a PKI platform, SignServer as a signing engine, and Keyfactor AgileSec for discovering cryptography.

Keyfactor also sells Keyfactor Command for IoT, an identity platform for manufacturers, and describes automotive OEMs and suppliers as needing identity-first security for vehicles and charging components. Both companies address post-quantum readiness: DigiCert announced general availability of Quantum Central on September 24, 2026, while Keyfactor's Command finds hybrid and PQ certificates. DigiCert says its X9 PKI began with the financial services industry's need for an interoperable trust framework, and DTCC will require X9 PKI certificates for connections to IBM MQ, Connect:Direct, and FTPS.

Keyfactor is headquartered in Independence, United States, and is privately held. On July 6, 2026, Keyfactor announced a growth investment of over 1 billion dollars from Summit Partners. On July 27, 2026, it announced its intent to acquire Cofide, a UK-based identity platform for software workloads and AI agents. Keyfactor said on September 9, 2026 that it exceeded 200 million dollars in annual recurring revenue at the beginning of Q3 2026.

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]
