Test Your SSL Server - Overview of GlobalSign's SSL Configuration Checker
GlobalSign's SSL Configuration Checker is an online tool that allows any organization to evaluate its site's strengths and weaknesses by simply entering its domain URL and then clicking submit.
Upon visiting GlobalSign's SSL Configuration Checker, powered by Qualys SSL Labs, organizations enter their website addresses and instantly receive a letter grade for their configuration. The grading system has three steps. First, the site's SSL certificate is examined to confirm that it is trusted and valid. If a server fails this step it is automatically given a zero. Next, the server configuration is tested in three categories: 1) protocol support, 2) key exchange support and 3) cipher support. Finally, a score between 0 and 100 is assigned to the site.
