What Is Endpoint Security?

Endpoint security refers to the strategies, tools, and practices used to protect the individual devices (endpoints) that connect to your business network. Every laptop, desktop computer, smartphone, tablet, and server in your organization is an endpoint — and each one is a potential entry point for cyber threats. Endpoint security aims to secure these devices against malware, ransomware, phishing attacks, and unauthorized access.

Modern endpoint security goes far beyond traditional antivirus software. Today's solutions include Endpoint Detection and Response (EDR), which continuously monitors device activity for suspicious behavior; application whitelisting, which only allows approved software to run; disk encryption to protect data if a device is lost or stolen; and automated patch management to close security vulnerabilities. Many endpoint security platforms also include threat intelligence that identifies and blocks emerging threats based on data from millions of devices worldwide.

For businesses with remote or hybrid workforces, endpoint security is especially critical. When employees work from home, coffee shops, or client sites, their devices operate outside the protections of your office network. A comprehensive endpoint security strategy ensures that every device is protected regardless of where it connects from, and gives your IT team visibility into the security posture of every machine in your environment.
