Frequently Asked Questions

Learn more about how this tool works and standard configurations

It audits the SSL/TLS deployment parameters of a target domain name. It checks active protocol support (TLS 1.2, TLS 1.3), cipher suite algorithms (e.g. forward secrecy support), certificate expiry details, trust status, and the presence of HSTS.
Legacy protocols contain cryptographic weaknesses (such as vulnerable block ciphers and susceptibility to POODLE/BEAST attacks) that allow attackers to eavesdrop on connections. Modern standards require restricting support to TLS 1.2 and TLS 1.3.
Regular audits are highly recommended. Checking certifications every quarter or automating expiry scans prevents certificate outages, which trigger browser security alerts and block visitor traffic.
