DigiCert Device Trust Manager vs DigiCert Private CA: 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.

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.
