Yesterday, Qualys released a new SSL test with updated guidelines.
Until that moment, our page at https://sixsafe.com/ scored straight A in their test. Now we only score A-. Check it out for yourself! Then check your own page! The reason for this is that the new test includes new guidelines on Forward Secrecy. For some combinations of browsers by a certain OS company, we don't provide Forward Secrecy, leading to a downgrading.
Unfortunately, there's not much I can do about this, because our web server does not support the necessary ciphers in the version we're using. So for the moment, we'll stay at A- and update our Forward Secrecy at some later point.
