Every morning a report lands on Tony Bisulca's desk with information he needs but wishes he didn't have to know. As he takes a sip of Earl Grey tea, he opens the multi-page document full of networking traffic stats from the previous day. He knows who the top bandwidth users were, the top surfers and chatters, where they went and when, what they downloaded and how long they stayed. This particular morning, he discovers that a co-worker, who is also a friend, tried to access a white supremacy site the previous night.

Bisulca's routine underscores what is increasingly no secret: When it comes to workplace computer use, someone is watching, and it's probably the CIO.
