The product builds a detailed view of the enterprise security posture across multiple clusters and clouds, including certificates that have been manually created by developers, and proactively identifies operational issues based on cert-manager status and health, as well as X.509 certificate misconfiguration. The full interface can be set-up to run for free on a single cluster and customers can upgrade for advanced multi-cluster and alerting capabilities.
