Wifi certificate is listed as "not secure" so my business website would not let me sign on and stay signed on. I called IT and despite their declarations that it was safe, and told me to hit "proceed" don't expect a secure business website to let you do business while signed on here. Very disappointing because i basically could not do chart work or answer patients questions on my work portal because of their stupid certificate status.
