When most MSPs inherit a client environment it is not a clean slate. You get a spreadsheet maybe, a Visio diagram from three years ago, and a promise that “yes, we know what’s on the network.” Then you start scanning and find the printer running on an unpatched firmware that hasn’t been touched since 2019, the rogue switch someone plugged in during a renovation, and four servers that IT forgot to decommission. That’s not a client’s problem.
