What is EDR?

What is EDR?

Endpoint Detection and Response (EDR), also known as endpoint detection and threat response (EDTR) is a component of an organization's cybersecurity strategy. It continuously monitors end-user devices, providing real-time visibility into potential threats and enabling proactive response measures. 


Understanding EDR

EDR is a security solution designed to monitor and protect endpoints, such as laptops and mobile devices, against cyber threats. It records and stores endpoint-system-level behaviors, analyzes data using various techniques, detects suspicious activities, and provides remediation suggestions to restore affected systems. EDR solutions ensure that any potential threats are promptly detected and responded to by continuously monitoring endpoints.


How does EDR work?

EDR security solutions work by recording and analyzing activities and events taking place on endpoints and workloads. This continuous monitoring provides security teams with real-time visibility into potential threats that would otherwise remain invisible. An effective EDR solution should offer advanced threat detection, investigation, and response capabilities.

Key aspects of an effective EDR solution

Endpoint visibility

An effective EDR solution should provide real-time visibility across all endpoints, allowing security teams to view adversary activities and respond promptly.


Threat database

EDR requires a comprehensive threat database, enriched with context, to mine for signs of attack using various analytic techniques.


Behavioral protection

EDR solutions should employ behavioral approaches to detect indicators of attack (IOAs) and suspicious activities before a compromise occurs.


Insight and intelligence

Integration with threat intelligence provides contextualized information, including details on the adversary and other relevant attack information.


Fast response

An effective EDR solution enables fast and accurate incident response, allowing organizations to stop attacks before they escalate into breaches.


Cloud-based solution

Cloud-based EDR solutions ensure zero impact on endpoints while providing real-time search, analysis, and investigation capabilities.

Why EDR is important?

Prevention alone is insufficient

While prevention measures are necessary, they cannot guarantee 100% protection. EDR fills the gap left by prevention measures, ensuring that potential threats are promptly detected and responded to.


Adversaries can linger undetected

Adversaries can remain undetected within an organization's network for extended periods, creating backdoors for future attacks. EDR enables organizations to detect and respond to these threats before they can cause substantial damage.


Enhanced visibility for effective monitoring

Traditional security solutions often lack the visibility required to effectively monitor and understand endpoints. EDR provides comprehensive visibility, allowing organizations to rapidly identify, investigate, and remediate security incidents.


Access to actionable intelligence

EDR solutions integrate threat intelligence, providing organizations with actionable insights into the attacks they face. This intelligence enables security teams to respond effectively and prevent breaches.


Data alone is insufficient

Collecting data is only part of the solution. EDR provides the necessary resources to analyze and derive value from the collected data, empowering security teams to address security incidents effectively.


Expedited remediation

Without adequate visibility and response capabilities, incident remediation can be protracted and costly. EDR enables organizations to quickly identify and respond to security incidents, minimizing the impact on business operations.



What is EDR vs antivirus?

Traditional antivirus software is installed directly on a device or server to protect it from malicious programs. An EDR system, on the other hand, is software that detects and halts cyber threats while providing visibility and control over devices on a network.


Why do we need EDR?

Endpoint detection and response (EDR) is a tool that supplements endpoint security by increasing your device's capabilities to detect malicious activities. 


What is the difference between EDR and SIEM?

EDR is better at detecting threats that are already on the endpoint, such as malware infections. SIEM is better at detecting threats that are coming into the network, such as malicious traffic.
