Website Security with SSL. An easy way to check your website security is to use Qualsy SSL Labs.
SSL Server Test (Powered by Qualys SSL Labs)
You basically enter your website URL link and then it will scan and give you a grade. No one wants to go back to school but this is a easy way to understand. I’ve gone from getting and F to and A+ with very little tweaking!
It will first check for TLS 1.2 and 1.3 and others such as DROWN.
You might run the check now and fix the issues. Then not do anything for a year and you are down from and A to a C. The reason for this is you running need to keep checking at minimum monthly to keep everything updated.
