What Is EDR?

What Is EDR?

 Last update: November 25, 2023

EDR (Endpoint Detection and Response) is a cybersecurity technology that provides continuous monitoring, detection, and response capabilities for endpoint devices such as laptops, desktops, servers, and other network-connected devices.

EDR solutions are designed to identify, investigate, and remediate threats that traditional antivirus or anti-malware tools might miss.

4 Critical Functions Provided by EDR

EDR solutions typically perform the following functions:

1. Collect and Analyze Data

EDR tools gather data from endpoints, including process and application behaviors, file access, and network activity. They then analyze this data to identify signs of malicious activity or potential security incidents.

2. Detect Threats

By employing advanced detection techniques such as behavioral analysis, machine learning, and threat intelligence, EDR tools can identify known and unknown threats, including advanced persistent threats (APTs), zero-day exploits, and fileless attacks.

3. Respond to Incidents

EDR solutions provide response capabilities to contain and remediate threats, such as isolating infected devices, terminating malicious processes, or rolling back system changes caused by an attack.

4. Investigate Incidents

EDR tools enable security teams to conduct forensic analysis of security incidents, trace attack chains, and identify the root cause of an attack.

When Would You Use It?

EDR solutions should be used in organizations that want to enhance their endpoint security posture, particularly in cases where

  1. Traditional antivirus or anti-malware solutions are insufficient for detecting advanced threats.
  2. The organization has a large number of endpoints, making manual monitoring and analysis infeasible.
  3. Compliance requirements dictate the need for continuous monitoring and reporting of endpoint activity.
  4. Security teams need tools to help them investigate, respond to, and remediate security incidents more efficiently.

5 Popular EDR Options

Some of the popular EDR options available in the market are:

1. CrowdStrike Falcon

CrowdStrike Falcon is a cloud-based EDR solution that provides threat detection, incident response, and threat hunting capabilities.

It uses artificial intelligence and machine learning techniques to identify and respond to advanced threats in real-time.

2. Microsoft Defender for Endpoint

Formerly known as Microsoft Defender Advanced Threat Protection, this EDR solution is integrated with the Microsoft ecosystem, providing advanced threat detection, investigation, and response capabilities for Windows, macOS, Linux, and mobile devices.

3. SentinelOne Singularity

SentinelOne Singularity is an AI-driven EDR platform that offers real-time visibility, threat detection, and response capabilities across various endpoint devices.

It also provides automated remediation and rollback features to reverse the effects of a cyberattack.

4. Carbon Black (VMware Carbon Black Cloud)

Carbon Black, now part of VMware, offers a cloud-native EDR solution that combines advanced threat detection, prevention, and response capabilities.

It provides real-time visibility into endpoint activities and leverages machine learning for threat detection.

5. Cybereason EDR

Cybereason EDR is an endpoint protection platform that focuses on detecting and remediating advanced threats.

It offers threat hunting, behavioral analysis, and incident response capabilities to help security teams identify and mitigate risks.

These are just a few examples of EDR solutions available in the market.
