AWS Certificate Manager vs KeyTalk CKMS

AWS Certificate Manager (ACM) provisions, manages and deploys public and private SSL/TLS certificates for AWS, hybrid and multicloud workloads. Certificates may cover one domain, multiple named domains, wildcard domains or combinations. Management is available through the AWS Management Console, AWS CLI and ACM APIs, with usage auditable in AWS CloudTrail logs. Amazon-issued certificates can renew automatically when DNS validation is used; otherwise ACM sends notices as expiration approaches. Public-certificate integrations include Elastic Load Balancing, Amazon CloudFront, Amazon API Gateway, AWS Elastic Beanstalk and AWS CloudFormation. AWS Key Management Service helps protect stored private keys. Customers can import third-party CA certificates and deploy them with Elastic Load Balancers, CloudFront and API Gateway; importing costs nothing. The default quota is 10 domain names per certificate, with requests up to 100. The integrated-services public-certificate plan is free and non-exportable. ACM is available on web and API platforms.

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.
