Cryptosense Discovery is our free tool to test a host’s usage of cryptography for common configuration mistakes and vulnerabilities. Discovery’s new version discovers more hosts and more vulnerabilities, and improves the visual representation of attacks. We achieve this by using a visualization method called attack trees. Attack trees do not simply report scores: they explain why a host is vulnerable and what the user must fix first. This greatly eases the hard job of correctly configuring TLS servers — especially at scale, when prioritizing tasks is not always trivial.
