In their own words
KeyTalk CKMS
KeyTalk CKMS automates PKI implementation and the enrollment, distribution and management of digital certificates. It keeps certificates and keys in a central repository and supports automated or semi-automated deployment and renewal, alongside reporting, notifications and alerts. Smart Security Scan finds certificates and keys on a network so valid findings can be imported. The product includes a private certificate authority that can operate beneath an existing root or as a standalone root. Integrations and protocols include DigiCert, DigiCert QuoVadis, GlobalSign, Microsoft CA, Intune, MobileIron, load balancers, HSMs, Citrix, SCEP and ACME. Access controls include AD and Entra ID authorization, multifactor authentication and role-based controls. CKMS can run as a virtual machine on customer infrastructure, in private cloud environments such as AWS, Azure and Google Cloud, or as KeyTalk-managed PKI service. General CKMS pricing is on request, and a free trial is available. Separate S/MIME plans cost €5 a month for on-premise service and €6.50 a month for hosted SaaS, billed per user per month.
OpenCA PKI
OpenCA PKI is free, open-source software for establishing and managing a public key infrastructure, with an out-of-the-box Certification Authority. It is intended for on-premises deployment and is listed for Linux, macOS, self-hosted, and web environments. The project says it implements commonly used protocols with full-strength cryptography; listed capabilities include SCEP support, HSM integration, and certificate profiles. The download page lists OpenCA PKI (SpecialK) version 1.5.1. Installation requires other software, including OpenLDAP, OpenSSL, Apache, and Apache mod_ssl, and OpenCA Tools version 1.3.0 is listed as a prerequisite to install first. The project dates to 1998 and describes its work as volunteer-driven and managed through collaboration and consensus. Community support is available through mailing lists, forums, and online chat; independent third parties offer paid support. Security concerns can be reported privately by email or publicly through the project issue trackers. The documentation page says downloadable documentation is unavailable and notes that the OpenCA Guide for version 0.9.2 is outdated in some parts.
