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.
