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

DigiCert ONE

Enterprise and mid-market teams managing PKI at scale will get the most from DigiCert ONE because it actually automates certificate lifecycle management across disparate trust domains, not just TLS/SSL renewals. The platform covers five distinct trust surfaces simultaneously: public CAs, private PKI, code signing, IoT device certificates, and DNS infrastructure, which means you're not stringing together point solutions. The post-quantum cryptography readiness is table stakes for anyone with a five-year planning horizon. This isn't the pick for smaller organizations that only need a certificate management dashboard or teams that want to avoid PKI complexity altogether; DigiCert ONE assumes you've already committed to centralized governance as an operational control.

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.
