EZCA

EZCA is a managed Cloud PKI and Certificate Authority for hybrid and cloud workloads, built by ex-Microsoft PKI engineers and the first of its kind on the market. EZCA replaces complex on-premises AD CS deployments and per-user cloud PKI services with a managed cloud CA priced at a flat $200 per certificate authority per month, with no surprise charges as you scale. SOC 2 Type II, ISO 27001, and FIPS 140-2 Inside, out of the box. EZCA delivers deep native integrations with Microsoft Entra ID, Intune, Azure Key Vault, and Azure IoT Hub, so Microsoft-centric teams get certificates issued, rotated, and consumed by Azure workloads following Microsoft best practices, without the expired certs, outages, and manual NDES connectors that haunt legacy PKI. Built-in support for ACME, SCEP, OCSP, and smartcards covers every certificate workflow a modern enterprise runsm, including scenarios Microsoft Cloud PKI does not: SCEP for Intune, Jamf, and other MDM platforms, smartcard issuance, Azure IoT Hub authentication, and one-click Azure Key Vault certificate rotation. For platform and security teams, EZCA's integration with public PKI providers automates the certificate lifecycle end-to-end: critical now that Apple and Google have set a course toward 47-day TLS certificates. What used to require a handful of renewals a year will soon require dozens per certificate; EZCA's automation, monitoring, and alerting handle the volume so teams don't have to. Common deployments include: - Replacing AD CS without standing up a new CA hierarchy or NDES servers - Issuing device certificates at scale via Intune, Jamf, and other MDM platforms (Windows, macOS, iOS, and Android) - Securing Wi-Fi and VPN with certificate-based authentication via EZRADIUS - Authenticating IoT and healthcare devices with X.509 in Azure IoT Hub - Workload identity and encrypted communications for internal APIs, microservices, and containers - Auto-rotating TLS certificates stored in Azure Key Vault Unlike traditional PKI vendors that require complex CA hierarchies, hardware provisioning, and per-user pricing that punishes growth, EZCA is delivered as a fully managed service. HSM-backed roots, high availability, disaster recovery, and 24/7 support are included by default. There are no agents to install on servers and no on-prem connectors to maintain. EZCA is available in the Azure Marketplace, Microsoft Security Store, and Jamf Marketplace, and is trusted by enterprises in healthcare, finance, manufacturing, and critical infrastructure to secure identity, encrypt communications, and govern certificate lifecycles across hybrid, cloud, and IoT environments.
