“right, I don’t want it but when I told the IT co I don’t want it he sent me a waiver exonerating himself (IT co) from ANY responsibility if there’s an issue.”
OF COURSE.
That’s the leverage they use to get you to pay the $500/mo for internet filtering.
Tell them you do NOT want internet filtering. You want internet site LOGGING that only you and your IT manager can look at. Logging will tell you IF somebody is doing something nefarious. And you can then take it up with the individual.
There is no liability to free them from.
Good guidance
