"Certison's ability to notify our team through Slack and e-mail, offers great value for us. Certison enables us to always be up to date and to react before anything disastrous happens to our own or our customer's e-services. The ability to oversee the health status of a multitude of https-certificates has proved out as extremely valuable."
