We recently installed a new SSL certificate for "isc.sans.org" . Our goal was to support some of the old ISC hostnames like incidents.org. However, we had reports that some browsers didn't support the new certificate. As of today, this should be fixed. However, if you are still having issues, please let us know.
Before you send your message, please click on the "Debug" link at the bottom of the page (it is a bit hidden in the dark blue footer). Please include the output of the debug page to make it easier for us to help you. This is true for other bug reports as well.
Bug reports may be submitted via our contact page  or via email to email@example.com .
URLs to test the SSL certificate: https://isc.sans.org/login.html and https://isc.sans.edu/login.html (the index page includes content from non-SSL sites)
Another "public service" announcement: Our URLs end in ".html" for the last couple years. However, many links still point to the old ".php" version. We are using redirect to accommodate them. If you are linking to ISC, please make sure you link to the ".html" version.
