Why Do XDR and NDR Technologies Exist?

XDR and NDR technologies exist to monitor networks and systems for threats, but each does it in its own way. NDR is designed to monitor what’s happening inside the network. Think of it as a sentinel that monitors network traffic for anything suspicious. It’s an expert at its job, but it only deals with the network part.

Let’s give an example of NDR: With an Antivirus or an Endpoint Detection and Response system, the network administrator or an external Cybersecurity team can collectively “see” the malicious actions occurring on computers with special monitoring software installed. But what happens when a device without the monitoring software connects to the network and performs malicious actions? That’s where the NDR is needed, which sends the firewall logs to the monitoring team, who will be aware of the malicious actions of an unprotected device.

On the other hand, XDR is a more comprehensive security solution that monitors services not on our local network, but in the cloud, outside our infrastructure (e.g., in a Microsoft 365 Tenant or Google Workspace). It collects data not only from the network but also from Cloud Services, emails, and other external points. Thus, it can combine all this information to detect and monitor threats and malicious actions outside the boundaries of our local network more quickly and effectively. It’s like having a central system that sees everything and protects you everywhere, not just on your local network.

What is NDR?

Το NDR (Network Detection and Response) επικεντρώνεται στην ανίχνευση και απόκριση σε απειλές μέσω της παρακολούθησης της κίνησης του δικτύου. Αυτή η τεχνολογία χρησιμοποιεί αισθητήρες δικτύου για να παρατηρεί και να αναλύει την κυκλοφορία που ρέει μέσω του οργανισμού. Οι ανιχνεύσεις του NDR βασίζονται σε ανώμαλες ή μη εξουσιοδοτημένες δραστηριότητες, όπως χρήση θυρών και πρωτοκόλλων που δεν συνάδουν με τη συνήθη λειτουργία.

This makes it ideal for organizations that want to strengthen their security in a more holistic way.

How Does NDR Work?

NDR (Network Detection and Response) works by installing sensors at strategic points on your network, either physically or virtually. These sensors monitor real-time traffic, capturing and analyzing data as it travels to its destination. The detections are based on advanced algorithms that analyze traffic to identify abnormal or unauthorized activity, such as using unusual ports and protocols.

If something suspicious is detected, the system can trigger alerts, shut down network traffic, or even isolate the infected device from the network, if possible. This approach offers a generalized view of the environment, ensuring that any suspicious activity on our network is recorded and analyzed. Using sensors and network analysis ensures that businesses can react quickly and effectively to threats.

The Benefits of NDR for Your Business

1. Broader Visibility: Provides a complete picture of network traffic, enabling threat detection at multiple levels. This visibility is critical for accurate security management.
2. Proactive Approach: Detects threats before they become serious incidents, reducing the likelihood of breaches. This allows businesses to react proactively, ensuring the integrity of their systems.
3. Abnormal Behavior Detection: Using analytical tools, behaviors that do not match normal operations are identified, helping to address threats immediately. For example, when a malicious user sends a large amount of data outside your network.

What is XDR?

XDR (Extended Detection and Response) is a more advanced version of NDR technology. It is a single platform that combines data from end devices, networks, and third-party applications for comprehensive detection and response.

This is where things get more advanced, as XDR combines EDR, NDR, and other tools to provide a comprehensive protection shield.

While NDR focuses primarily on monitoring network traffic, XDR extends this capability and includes information from various sources, more effectively detecting threats.

How XDR Works and How It Relates to NDR

XDR collects and correlates data from multiple sources to identify complex threats that on-premises systems may not detect. In contrast, NDR focuses primarily on monitoring Cloud Services. XDR takes this capability of NDR and extends it to data from multiple other sources.

A key advantage of XDR is its ability to unify information from multiple platforms and devices, providing comprehensive visibility into the security environment. It can monitor not only network traffic but also activity in enterprise applications and third-party services such as Microsoft Teams, Google Workspace, and other cloud applications, detecting unusual behaviors that may indicate a threat.

Additionally, XDR can connect to IoT devices, such as smart light bulbs or thermostats, to monitor suspicious activity, providing greater visibility and threat detection. This enhances the enterprise’s ability to address modern threats effectively.

XDR’s unified platform allows analysts to monitor detections and respond to threats from a central console, saving time and improving efficiency. Connecting XDR to NDR combines the advantages of both technologies, ensuring a timely and effective response to threats.

The Benefits of XDR for Your Business

1. Integrated Approach: Combines multiple data sources (e.g., Microsoft 365, Google Workspace, Email) to provide a complete view of detections, seeing what is happening not only on end devices but also between them.
2. Streamline Operations: This feature allows analysts to view and respond to threats from a single console, reducing response times and improving efficiency.
3. Faster Response Time: XDR‘s unified approach enables rapid response to threats, reducing the risk and impact of attacks.

Relationship of NDR and XDR with EDR, TDR & MDR

Understanding how NDR and XDR work together with other technologies, such as EDR, TDR, and MDR, is important to provide comprehensive security. EDR (Endpoint Detection and Response) protects endpoint devices, such as computers, tablets, and mobile phones, ensuring that attacks on them are immediately isolated and neutralized. TDR (Threat Detection and Response) also focuses on detecting and responding to threats, often leveraging automation and artificial intelligence to identify sophisticated attacks.

Finally, MDR (Managed Detection and Response) offers a managed service where our specialized teams monitor and take action in the event of a cyberattack without needing a dedicated team within your organization to manage security incidents. These technologies work together to ensure complete coverage and continuous protection against modern threats.
