Security convergence means bringing together different kinds of security technology and combining it into a single system. Imagine that you have an old house where you have separate locks and alarms on the door, windows, and garage. With security convergence, you can have all of these locks and alarms connected together into one system so that it's easier to use and manage. This way you can control all of the locks and alarms with just one device instead of having to manage them separately. It also makes it easier to identify possible problems or areas of vulnerability and make sure they're taken care of.
