What does EDR mean in business?

EDR stands for Endpoint Detection and Response. It is a cybersecurity technology that helps detect, investigate, and respond to advanced threats and targeted attacks on endpoints and networks.

What is Endpoint Detection and Response (EDR)?

Endpoint detection and response (EDR) is a solution that helps organizations monitor and respond to suspicious activities and issues on endpoints and networks. The key capabilities of EDR solutions include:

  • Continuous monitoring and recording of endpoint activity
  • Advanced behavioral analysis to detect malicious behavior
  • Real-time alerting on potential threats
  • Contextual investigation of alerts and incidents
  • Automated response and remediation actions

EDR tools provide continuous visibility into endpoint activity and help security teams quickly detect, investigate, and mitigate advanced threats that may evade traditional security defenses. They enable faster incident response and reduce the impact of breaches.

How does EDR work?

EDR solutions consist of software agents that are installed on endpoint devices, a centralized server or platform, and a management console. Here is how EDR tools work in a nutshell:

  • Lightweight software sensors are deployed to endpoints like laptops, desktops, and servers. These collect detailed information on system activities.
  • The telemetry data is continuously analyzed using advanced techniques like machine learning and behavioral analysis models to detect anomalies and threats.
  • When a potential threat is detected, the EDR platform generates an alert. Analysts can investigate the activities leading up to the event using historical evidence.
  • Tools provide context and visibility into the scope of attacks. Analysts can identify affected systems, understand threat behaviors, and determine root causes.
  • EDR platforms enable containment and remediation actions like isolating infected nodes, killing malicious processes, and rolling back changes.
  • Teams can leverage threat intelligence to improve detection and automate response procedures.

EDR Use Cases

Here are some of the key use cases and benefits of EDR solutions for security teams:

  • Faster Threat Detection: EDR provides continuous monitoring of endpoint activity and can quickly spot malicious patterns and behaviors that may be indicators of compromise.
  • Improved Incident Response: Detailed endpoint visibility and forensic data allow analysts to rapidly investigate potential incidents and establish root causes.
  • Automated Threat Containment: EDR tools can isolate infected endpoints, kill malicious processes, and prevent threats from spreading across the network.
  • Accelerated Threat Hunting: Proactive threat hunting leverages EDR data to uncover difficult-to-detect intrusions and adversary behaviors across the infrastructure.
  • Compliance Benefits: Detailed endpoint activity logs help demonstrate compliance with regulations and support audits.

Benefits of EDR

Here are some of the key benefits organizations can realize by deploying EDR solutions:

Faster Detection of Advanced Threats

Many sophisticated, stealthy attacks like fileless malware and ransomware can bypass traditional perimeter defenses. EDR provides continuous monitoring and behavioral analytics to quickly catch advanced threats.

Improved Visibility Into Endpoints

EDR tools collect detailed telemetry from endpoints, providing complete visibility into their state and activities. This allows quicker investigation and response.

Enhanced Incident Response

EDR platforms capture rich forensic data that speeds up the investigation of alerts, enables identifying root causes, determining attack scope, and guides containment.

Rapid Threat Containment

Real-time capabilities allow security teams to promptly isolate compromised endpoints and stop threats before they spread widely across the network.

Proactive Threat Hunting

EDR data permits regular threat hunting exercises to uncover difficult-to-detect intrusions and adversary behaviors across the infrastructure.

Compliance and Audit Support

Granular endpoint activity logs provide evidence of policy compliance and support audits and investigations.

EDR vs. Antivirus

EDR solutions provide significant advantages over traditional antivirus software. Here is a comparison between the two technologies:

Capability EDR Antivirus
Detection Technique Behavioral analytics, machine learning Signature-based
Protection Against Advanced threats like fileless attacks, zero days, ransomware Known malware for which signatures exist
Visibility Complete visibility into endpoints Limited visibility into malware activities
Forensics Rich endpoint data supports rapid forensics Limited forensic evidence
Incident Response Automated containment capabilities Manual response procedures

While antivirus still has value in stopping known attacks, EDR provides a more modern approach to endpoint security with advanced threat detection, visibility, and response capabilities.

Choosing an EDR Solution

Here are some important criteria to consider when evaluating EDR tools:

Detection Accuracy

Accuracy in detecting advanced threats with low false positives is critical. Evaluate detection rates against diverse threats.

Endpoint Visibility

Look for comprehensive visibility into endpoint activities with detailed event logging and process tracking.

Threat Intelligence

Choose a solution that leverages global threat intelligence to detect emerging attacker tools, techniques, and procedures.

Incident Investigation

Prioritize products that provide context-rich alerts to accelerate investigations and threat hunting.

Response Automation

Opt for platforms with automated containment capabilities like isolating endpoints and killing processes.

Cloud Delivery

SaaS-based solutions remove the need to deploy and maintain infrastructure.


Check for integration capabilities with other security controls like firewalls, SIEMs, and IT systems.


Evaluate both licensing costs and operational expenses like staffing needs.
