These days, everything is connected to everything else. Endpoints are the most important parts of modern networks because they let people communicate and run processes. But what does an ending really mean? An endpoint is any device that can join a network. This includes laptops, smartphones, tablets, servers, and even Internet of Things (IoT) devices like smart thermostats and wearable tech. People can connect to networks with these devices, but they also have security holes that hackers can use.
