If you're that worried about your company spying on what you're doing on the internet, then SSL-encrypting your session is the least of your worries. You should be more worried that they feel the need to spy on you at that level, or that you're surfing INGO on company time, or any one of a dozen other things. Seriously, just browse at home and get back to work already.
Half of INGO just logged off. LOL
