Antivirus (AV) :

💠 Focus: Detects and removes known malware (e.g., viruses, worms, Trojans).

💠 Method: Relies on signature-based detection for identifying threats.

💠 Purpose: Baseline protection against common malware.

💠 Scope: Blocks known threats but struggles with advanced, unknown attacks.

Endpoint Detection and Response (EDR) :

💠 Focus: Monitors and mitigates advanced threats on endpoints.

💠 Method: Uses behavioral analysis, threat hunting, and real-time monitoring.

💠 Purpose: Provides deeper visibility and control to handle unknown and targeted attacks.

💠 Scope: Responds to suspicious activities on individual devices.

Extended Detection and Response (XDR) :

💠 Focus: Delivers cross-platform, holistic threat detection and response.

💠 Method: Integrates data from multiple tools (e.g., AV, EDR) for better threat correlation.

💠 Purpose: Comprehensive security by connecting insights across different layers.

💠 Scope: Broad coverage across networks and endpoints, enhancing protection against complex attacks.
