In their own words
EZCA
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.
