SSL Grade

Set the target SSL grade level as assessed by the SSL Labs Test.
Please notify support if the selected level no longer receives a matching score from SSL Labs.

Grade A configures the address to use higher SSL standards. This configuration creates a more secure connection between the server and the user.

Grade B offers more compatibility with older browsers and systems, but is considered less secure. More information about why is available here: https://rfc-editor.org/rfc/rfc7525
