What is Endpoint Security?

Quick answer

Protecting devices such as laptops, phones, and servers that connect to a network from malware, exploitation, and misuse.

Endpoint Security, explained

Every device that connects to a corporate network is an endpoint and a potential entry point for attackers. With remote work and personal devices, the number and variety of endpoints has grown, making them a frequent target.

Endpoint security has evolved from traditional antivirus, which matched files against known malware signatures, to endpoint detection and response (EDR) tools that monitor behavior, such as a word processor suddenly launching a script, and let analysts investigate and isolate infected machines. Other components include disk encryption, device management, patching, application control, and firewalls on each device. XDR platforms extend this visibility by correlating endpoint data with network, email, and cloud signals.
