Gartner defines an endpoint protection platform (EPP) as security software designed to protect managed endpoints — including desktop PCs, laptop PCs, virtual desktops, mobile devices and, in some cases, servers — against known and unknown malicious attacks. EPPs provide capabilities for security teams to investigate and remediate incidents that evade prevention controls. EPP products are delivered as software agents, deployed to endpoints, and connected to centralized security analytics and management consoles.

EPPs provide a defensive security control to protect end-user endpoints against known and unknown malware infections and file-less attacks using a combination of security techniques (such as static and behavioral analysis) and attack surface reduction capabilities (such as device control, host firewall management and application control). EPP prevention and protection capabilities are deployed as a part of a defense-in-depth strategy to help reduce the endpoint attack surface and minimize the risk of compromise. EPP detection and response capabilities are used to uncover, investigate and respond to endpoint threats that evade security protection, often as a part of broader threat detection, investigation and response (TDIR) capable products.

Extended detection and response (XDR) delivers security incident detection and automated response capabilities for security infrastructure. XDR integrates threat intelligence and telemetry data from multiple sources with security analytics to provide contextualization and correlation of security alerts. XDR must include native sensors, and can be delivered on-premises or as a SaaS offering. Typically, it is deployed by organizations with smaller security teams.
