Certificate Tracker lets people scan FQDNs for their SSL certificates. It can also scan across various DNS resolutions, useful for organizations with split DNS that resolve certain FQDNs differently on a local network versus publicly.
It is one of TheJack’s sub modules and can run under TheJack or standalone. It is planned to be made publicly available at satools.dev, though that site is not live yet.
It is nearing completion. The source is closed for now, with the intention to open it up so teams can run their own instance. The same certificate-scanning capability may also land inside SATools.
