As a contractor or a full time employee at the 70k people companies? Was it in the past 10 years? If you used a company provided computer, did you investigate what was running? Did you go beyond the typical process manager and look into the kernel modules list?
They often don't disclose explicitly that this stuff is running, because it rightfully creeps people out and the 'security' types don't want people to know.
Contractor here, I mainly work on mega-big corporations. I always check what run on my PC. I never use the work machines for anything personal. FFS I don't even use their guest wifi. I stick to my data plan.
I have noticed the last few years that BlueCoat is on the rise. From some article a couple of months back I read that the company/Fund that owned BC also bought Sophos.
