Why NDR is so important

Networks are the foundation of today’s connected world, making them a prime target of cyber attackers looking to cause disruption. The high volume of data traveling across these networks makes it easy for attackers to hide their tracks. IBM Security® QRadar® Network Detection and Response (NDR) helps security teams by analyzing network activity in real time. It combines depth and breadth of visibility with high-quality data and analytics to fuel actionable insights and response.

How it’s used

Lateral movement

Gain visibility into unusual activity

Given the high volume of data traveling across your network, it’s easy for threats to go unnoticed. Detect reconnaissance, pivoting and transfers between devices — which are indicative of malicious lateral movement — in real time.

Data exfiltration

Reduce dwell time with quick detection

Attackers are patient, often exfiltrating data in small, infrequent batches. Uncover sensitive data moving across your network in real time by way of emails, chat messages, file uploads and downloads or social media.

Compromised devices

Automatically update assets to stay ahead of attackers

Discover new devices as they connect to your network. Continuously profile assets based on attributes and behavior to uncover threats, compromised devices and shadow IT.

Threat hunting

Shift from reactive to proactive

Query historical network activity to search for past activity, discover unusual behavior, and identify the assets involved to help prevent similar attacks in the future.



Deeper understanding of system traffic

Threats hide within the volume of normal traffic on your network. Dive deeper into your network content to determine what is really occurring.

Increased visibility of data

Every organization has a wealth of critical data that must be protected. QRadar NDR can help you know what that data is, who is accessing it, and where it is moving.

Capture of the insights you need

Being able to quickly sift through a flood of daily security log data and continuously capture key data makes it easier to analyze what is happening across organizations.
