I worked for a very large insurance company until recently . IT is run like the Wild West. Contractors seem to do whatever they want.  after a merger several years ago, all the people who built the systems were driven out, leaving a bunch of low paid outsourced contractors to support everything. The entire IT infrastructure is a bad day from collapsing.
I am not surprised, when I worked for a hardware company (late 90's), the repair techs would fight over laptops that came in from churches because they always had the best porn.
