I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am not using any logins to some areas of my website.

using Qualys SSL Labs reports the following (among other stuff)
I get a A- because : The server does not support Forward Secrecy with the reference browsers. Grade reduced to A

Firefox 53 / Win 7  R            Server closed connection ( and others)

Edge 13 / Win 10  R            Server negotiated HTTP/2 with blacklisted suite
RSA 2048 (SHA256)   |  TLS 1.2 > h2    |  TLS_RSA_WITH_AES_128_CBC_SHA256
