Endpoint security refers to the practices and solutions network administrators use to protect the network from vulnerabilities stemming from devices and applications connected to them. These practices and solutions secure the endpoints these devices and applications create.
Today's sophisticated endpoint security ecosystem is an outgrowth from its earliest days of antivirus software into second- or next-generation antivirus measures, external threat monitoring and mitigation, and approved-device management such as mobile device management (MDM) platforms that administrators oversee. Endpoint security is quite broad today and also takes the form of encrypting data, enforced use of a virtual private network (VPN), and all kinds of compliance measurements and supporting tools that enforce compliance.
Endpoint security is becoming increasingly critical to organizations due to the upward trend in workers’ preference to work remotely.
Example:
"Endpoint security is a growing consideration for enterprises as more people choose to work remotely. The use of many more connected devices — corporate owned personal laptops and smartphones —as well as virtual desktops on employee machines creates many more endpoints that companies must safeguard."
