Endpoint Detection and Response (EDR)

EDR is a security solution that continuously monitors endpoint devices, detects suspicious activities, and provides automated response capabilities to investigate and contain threats.

EDR solutions provide visibility into endpoint activities and the ability to detect and respond to threats that evade traditional antivirus.

Key EDR capabilities: - Continuous Monitoring: Recording all endpoint activity - Threat Detection: Identifying suspicious behaviors and indicators - Investigation: Forensic tools to analyze incidents - Response: Automated or manual containment and remediation - Threat Hunting: Proactive search for hidden threats

EDR vs Traditional Antivirus: - Antivirus: Signature-based, blocks known malware - EDR: Behavior-based, detects unknown threats and provides response

Leading EDR vendors: - CrowdStrike Falcon - SentinelOne - Microsoft Defender for Endpoint - Carbon Black

EDR is increasingly expected for compliance, especially when handling sensitive data.

Why It Matters

Traditional antivirus misses 60% of modern threats that use fileless techniques, living-off-the-land attacks, and zero-day exploits. EDR provides the behavior-based detection and forensic capabilities needed to identify and contain these sophisticated attacks. Cyber insurers now commonly require EDR deployment as a condition of coverage, and SOC 2 auditors increasingly expect endpoint detection beyond basic antivirus.

SIEM

SIEM (Security Information and Event Management) is a platform that aggregates logs from multiple sources, correlates security events, and provides real-time alerting and analysis.

Incident Response

Incident response is a structured approach to preparing for, detecting, containing, and recovering from security incidents while minimizing damage.
