DigiCert Private CA vs Keyfactor Command for IoT: Side-by-Side Comparison (2026)

DigiCert Private CA

Mid-market and enterprise teams replacing aging on-premises certificate authorities should pick DigiCert Private CA for its genuine ADCS modernization path without forcing a full cloud migration. The platform supports hybrid deployments with FIPS 140-2 Level 3 hardware backing and spans identity management through infrastructure resilience (NIST PR.AA, PR.PS, PR.IR), meaning you get security depth across provisioning, issuance, and access control in one system. Skip this if you're purely cloud-native and want minimal operational overhead; DigiCert's hybrid strength is also its complexity tax.

Keyfactor Command for IoT

Enterprise and mid-market organizations deploying hundreds or thousands of IoT devices at scale will benefit most from Keyfactor Command for IoT because it handles certificate and key lifecycle management across heterogeneous hardware without forcing you to rebuild your device firmware. The platform supports TPM and secure elements natively, handles both symmetric and asymmetric key operations, and executes remote certificate renewal and revocation across fleets without manual touchpoints,critical when your devices live in the field for years. Skip this if your IoT footprint is under 500 devices or you're locked into a vendor's proprietary device identity solution; the operational overhead of centralized PKI management only pays for itself at true scale.
