Keyfactor

What Keyfactor actually does

Keyfactor manages machine identities—the certificates and cryptographic keys that authenticate servers, devices, workloads, and IoT endpoints. Its Command platform provides visibility into every certificate across the enterprise, regardless of which certificate authority issued it. When you have thousands of certificates spread across internal CAs, public CAs, cloud services, and IoT devices, Keyfactor shows you where they all are and when they expire.

The EJBCA platform is Keyfactor’s open-source-rooted certificate authority and PKI management system. It can replace or augment Microsoft AD CS for organizations that need more flexibility, scalability, or cross-platform support. For IoT manufacturers, Keyfactor provides identity provisioning at the factory level—embedding unique certificates into devices during manufacturing so they can authenticate securely throughout their lifecycle.

Keyfactor also addresses crypto agility, which is becoming critical as post-quantum cryptography approaches. The platform helps organizations inventory their cryptographic algorithms and plan migration paths when standards change. This is forward-looking but increasingly relevant as NIST finalizes post-quantum standards and regulators begin asking about quantum readiness.

Who it’s best for

• Enterprises with large certificate estates that have experienced outages from unexpected certificate expirations
• IoT and medical device manufacturers needing to provision and manage device identities at scale
• Organizations running internal PKI that want to modernize or replace aging Microsoft AD CS deployments
• DevOps teams issuing certificates for microservices, containers, and service meshes at high velocity
• Security teams preparing for post-quantum cryptography that need to inventory current cryptographic usage

Pricing reality check

Keyfactor pricing depends on the number of certificates managed, the platform components deployed, and whether you’re running on-premises or as a cloud service. Enterprise deployments typically start in the mid-five to low-six figures annually. IoT identity provisioning is priced differently based on device volumes.

EJBCA has a community edition that’s free and open source, which is a genuine entry point. Organizations can start with the open-source CA and add commercial management, automation, and support as their PKI matures. This freemium path is unusual in the enterprise security market and worth exploring before committing to a full commercial license.

Alternatives to consider

• Venafi — The other major player in machine identity management. Stronger in some enterprise policy enforcement features, generally more expensive, and longer sales cycles.
• DigiCert CertCentral — Certificate lifecycle management from a major public CA. Good if your primary need is managing publicly trusted certificates rather than full PKI.
• Smallstep — Developer-focused certificate management for cloud-native environments. More modern, lighter weight, but narrower scope than Keyfactor.
• HashiCorp Vault PKI — Secrets engine that can issue certificates dynamically. Good for DevOps use cases but not a replacement for full certificate lifecycle management.

The Charting Cyber take

Certificate management sounds boring until an expired cert takes down your payment processing at 3 AM. Keyfactor addresses a real operational problem that affects almost every enterprise but few invest in proactively. The platform’s breadth—from enterprise PKI to IoT device identity to crypto agility—is unmatched by most competitors.

The caveat is complexity and organizational readiness. Keyfactor assumes your team understands PKI concepts. If you don’t have someone who can explain the difference between an intermediate CA and a root CA, you’ll need training or consulting before the platform delivers value. The IoT identity use case is where Keyfactor particularly shines—provisioning certificates at manufacturing scale is a hard problem they’ve solved well. For organizations just looking to stop certificate expiration outages, start with the discovery and lifecycle management features and expand from there.
