A client asks for your Wi-Fi password. You give them the same one your whole business runs on.
It feels like ordinary hospitality, and underneath it is actually an open door.
Their phone, their laptop, whatever they walked in carrying, is now sitting on the exact same network as your files, your systems, and every device that matters to your business. You know nothing about the security of their device. You just plugged it in next to everything you care about.
One flat network means all of it lives in the same room as your critical systems.
The fix is old, standard, and boring. Segmentation puts guests and unmanaged devices in their own lane, walled off from the business.
Most small offices simply never set it up. Guest Networks are an easy way to bifurcate the traffic.
