They definitely started in the turnkey SME/consumer space, and still do a lot that's relevant there, but they've got a ton of very enterprise hardware targeted at large offices/campuses/stadiums and the like. There's APs specifically designed to be pointed at a sports or concert crowd and handle 1500+ active clients per access point at a time, and similarly specced switches and routers so that you can have TV crews turn up and hook into your network for live streaming.
