Gartner defines an endpoint protection platform (EPP) as security software designed to protect managed end-user endpoints — including desktop PCs, laptop PCs, and mobile devices — against known and unknown malicious attacks. Additionally, 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 interfaces.
SIEM is a configurable security system of record that aggregates and analyzes security event data from on-premises and cloud environments. SIEM assists with response actions to mitigate issues that cause harm to the organization and satisfy compliance and reporting requirements.
