EZCA vs Keyfactor Platform

EZCA is a cloud PKI service for running certificate authorities without operating the underlying PKI infrastructure yourself. It issues certificates through ACME, EST, and SCEP, and provides APIs for applications and workflows. Certificate uses include users, devices, applications, Wi-Fi, VPN, web services, and IoT, including device authentication for Azure IoT Hub and Azure IoT Central. Integrations include Azure, Entra ID, Intune, Azure Key Vault, and Azure applications; Intune and Jamf are supported for device certificates. EZCA can chain to an existing on-premises CA or bring an AD CS CA into a cloud setup. The maker says its CAs are HSM-backed, with Basic using FIPS 140-3 Level 2 and Premium Level 3. CA changes, requests, and approvals are logged for export to a preferred SIEM, and revocation checks use CRLs and OCSP. Basic costs $200 a month per CA, and a 30-day trial is available; there is no free plan. Plans differ in throughput, support, availability, and infrastructure options.

Keyfactor Platform, through Keyfactor Command, gives PKI, security, infrastructure, and DevOps teams visibility into certificates and tools to govern their lifecycle. It can inventory certificates from certificate authorities, scan networks for unknown SSL/TLS certificates, and connect to key and certificate stores. Teams can automate enrollment, renewal, revocation, and provisioning, with self-service workflows available through a user interface or API. Listed enrollment protocols are SCEP, ACME, and EST. Administrators can set role-based permissions, protect private keys with retention and storage policies, and require enrollment or approval workflows. Integrations span CI/CD, cloud, HSM, IoT, ITSM, public and private certificate authorities, and web servers. Deployment options are on premises, as a hosted certificate lifecycle service, or as fully managed PKI in a single-tenant cloud platform. Keyfactor says Command has been tested for deployments with more than 500 million certificates. A 30-day trial is offered. Pricing is available on request, and there are no per-certificate fees listed.
