Keyfactor is enterprise PKI infrastructure. CertLocker is an infrastructure trust operations platform for SRE and DevOps teams. They solve adjacent problems for different team sizes and budget profiles.
Keyfactor is an enterprise certificate lifecycle management platform designed for large organisations with complex PKI requirements — multiple internal CAs, HSM integration, compliance reporting, and dedicated PKI engineering teams. CertLocker is a focused infrastructure trust operations platform for SRE and DevOps teams that need certificate lifecycle, ACME automation, secrets management, SSH access control, and endpoint monitoring without enterprise-scale overhead or cost.

Keyfactor is a serious enterprise product with genuine depth in PKI orchestration. If you have 50,000 certificates across 20 internal CAs, dedicated PKI engineers, and a compliance team that needs detailed reporting, Keyfactor is built for that problem. CertLocker is not.
CertLocker is built for the infrastructure team that has 200–2,000 certificates, runs on bare metal or hybrid cloud, and needs certificate lifecycle, ACME automation, SSH access management, and secrets in one place without hiring a PKI consultant or signing an enterprise contract.
The genuine overlap is in mid-market teams that have outgrown spreadsheets and Certbot but are not yet at enterprise PKI scale. In that range, Keyfactor brings more PKI depth; CertLocker brings SSH access, secrets versioning, HAProxy integration, and a faster path to operational value.

Keyfactor is an enterprise certificate lifecycle management platform targeting large organisations with complex PKI requirements — multiple internal CAs, HSM integration, and compliance reporting. CertLocker is a focused infrastructure trust operations platform for SRE and DevOps teams that need certificate lifecycle, ACME automation, SSH access, and secrets versioning without enterprise-scale overhead.
Keyfactor is a better fit for large enterprise PKI programmes with multiple internal CAs, dedicated PKI engineers, HSM requirements, and compliance reporting needs at scale. It is particularly strong in regulated industries with existing enterprise PKI investment.
CertLocker is priced for infrastructure teams rather than enterprise PKI programmes. Keyfactor pricing is enterprise-contract based and typically involves significant per-certificate or per-endpoint fees. See CertLocker pricing for current plans.
