Practical guidance
Balance settings against actual client requirements. Old protocols create risk, while abrupt compatibility changes can exclude older equipment. Retest through the reverse proxy or CDN used in production.
Before using this tool
Define what you need from TLS configuration check and prepare the relevant input. When diagnosing a live service, record the test time and connection conditions so you can compare results after configuration changes. Check findings against the documentation for your software.
