Security threats are constantly evolving, making it difficult for organizations to protect their data and networks from malicious actors. Incident response is a process that helps organizations detect, contain, and mitigate these threats. Endpoint Detection and Response (EDR), Network Detection and Response (NDR), and Extended Detection and Response (XDR) are three security technologies that are used to detect and respond to incidents.
EDR is a security solution that focuses on analyzing the endpoint devices, such as laptops, desktops, and mobile devices, for suspicious activity. It uses a combination of behavioral analytics and machine learning to detect malicious activity and alert the security team. NDR is a security solution that focuses on analyzing the network, including traffic, devices, and applications, for suspicious activity.
It uses a combination of packet inspection, deep packet inspection, and machine learning to detect malicious activity and alert the security team. XDR is a security solution that combines the capabilities of EDR and NDR to provide a comprehensive view of the entire environment. It uses a combination of data sources, including endpoint devices, network traffic, and applications, to detect malicious activity and alert the security team.
In this article, we will compare EDR, NDR, and XDR to help you understand the similarities and differences between these three security technologies. We will also discuss the advantages and disadvantages of each to help you make the best decision for your organization’s security needs.
What is Incident Response?
Incident response is the process and procedure an organization follows when they detect and investigate a security incident. An incident response plan outlines the steps to take and who is responsible for each step in the event of a security incident. It also provides guidance on how to handle the incident and how to prevent similar incidents in the future.
The goal of incident response is to minimize the impact of the incident, contain it quickly, and restore normal operations in the shortest amount of time possible. It is also important to collect evidence and determine the root cause of the incident in order to prevent future incidents.
The incident response process typically involves four main steps: preparation, detection and analysis, containment and eradication, and post-incident activity.
- Preparation involves developing an incident response plan, training personnel, and implementing security measures.
- Detection and analysis involves identifying the incident, gathering evidence, and analyzing the data.
- Containment and eradication involves isolating the affected systems and eliminating the threat.
- Post-incident activity involves documenting the incident, notifying affected parties, and implementing measures to prevent similar incidents in the future.
Incident response is an essential part of any organization’s security program. It is important to have a plan in place so that the organization can respond quickly and effectively when a security incident occurs.
What Is EDR (Endpoint Detection And Response)?
Endpoint Detection and Response (EDR) is a security technology that provides organizations with the ability to detect, investigate, and respond to threats on their endpoints. It is an advanced form of endpoint security that uses advanced analytics and machine learning to detect malicious activity, while also providing automated incident response capabilities.
EDR solutions provide organizations with the ability to detect malicious activity on endpoints in real-time, as well as the ability to investigate the source of the threat and respond to it quickly.

What Is NDR (Network Detection And Response)?
Network Detection and Response (NDR) is a type of security technology that provides organizations with visibility into network-based threats and malicious activity. NDR solutions are designed to detect, investigate, and respond to malicious activity on the network in real-time.
NDR solutions provide organizations with the ability to detect malicious activity on the network, such as malicious traffic, malicious files, and malicious users. NDR solutions also provide the ability to investigate malicious activity and respond to it in real-time. This allows visibility on a “macro” or holistic scale instead of a point-by-point basis.
NDR solutions are typically deployed in the form of a network monitoring and security platform. This platform is designed to collect data from the network and analyze it for malicious activity. The platform then takes action to investigate and respond to any malicious activity that is detected. Oftentimes the purpose of an attack is not to compromise a single machine or system as a single endpoint has limited value. Attacks are often targeted and purpose-driven to compromise high-value targets or entire networks.
NDR solutions are often used in conjunction with other security technologies, such as Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR). By combining the visibility of EDR and XDR with the real-time detection and response capabilities of NDR, organizations can gain a comprehensive view of their security posture and respond quickly to threats.

Key Differences Between EDR, NDR, And XDR
When it comes to security, there are many different technologies to choose from. EDR, NDR, and XDR are three of the most popular options, each providing a different level of protection for organizations. While all three technologies are designed to detect and respond to cyber threats, there are some key differences between the three that should be considered when deciding which one is right for your organization.
EDR (Endpoint Detection and Response) is a technology that focuses on detecting and responding to threats at the endpoint level. It is typically deployed on individual endpoints, such as laptops or desktops, and monitors for malicious activity. If a threat is detected, EDR can take action to mitigate the threat.
NDR (Network Detection and Response) is a technology that focuses on detecting and responding to threats at the network level. It is typically deployed on the perimeter of the network and monitors for malicious activity. If a threat is detected, NDR can take action to mitigate the threat. NDR is also ideally positioned to monitor for threats that have malicious intent but are not malware per se, for example, insider threat activity is malicious and designed to cause harm or loss to an organization but does not necessarily violate any rules, so it does not cause any alert.
XDR (Extended Detection and Response) is a technology that combines the capabilities of EDR and NDR to provide a more comprehensive security solution. It is designed to detect and respond to threats at both the endpoint and network levels. XDR can detect malicious activity across multiple endpoints and networks, and can take action to mitigate the threat.
The key differences between EDR, NDR, and XDR are:
- EDR focuses on detecting and responding to threats at the endpoint level, while NDR focuses on detecting and responding to threats at the network level.
- XDR combines the capabilities of both EDR and NDR to provide a more comprehensive security solution. XDR is the next iteration of what SIEMs promised the industry 20 years ago.
- EDR and NDR are typically deployed on individual endpoints or networks, while XDR is designed to detect and respond to threats across multiple endpoints and networks.
Ultimately, the choice of which technology is best for your organization will depend on your specific security needs.
