DigiCert Device Trust Manager vs Keyfactor Command for IoT: Side-by-Side Comparison (2026)

DigiCert Device Trust Manager

Enterprise and mid-market teams managing IoT fleets at scale need DigiCert Device Trust Manager because it handles the messy reality of device identity from manufacturing through retirement, not just certificate issuance. The platform covers hardware-backed provisioning, zero-touch onboarding, and continuous threat monitoring across MQTT and Matter ecosystems, which means you're not bolting together three separate vendors to solve device PKI. Skip this if your IoT footprint is under 10,000 devices or you're locked into a single cloud provider's proprietary device management; the investment only pays off when you're dealing with heterogeneous hardware and complex supply chain compliance.

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.
