Why NDR is so important

Networks are the foundation of today’s connected world, making them a prime target of cyberattackers looking to cause disruption and a key source of data for threat detection and analysis.

IBM Security® QRadar® Network Detection and Response (NDR) helps your 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.

Read the solution brief
X-Force Threat Intelligence Index 2024

In 2023, 70% of cyberattacks targeted critical infrastructure industries. Check out the new report for deeper insight into attackers’ tactics.

Benefits Eliminate blind spots

Get comprehensive, real-time visibility for improved network detection and response by combining event and flow data across on-prem and cloud environments.

Detect threats faster

Use machine-learning based analytics to help determine a baseline of normal network activity to identify suspicious behavior quickly before attackers cause disruption.

Use existing investments

Enable broad threat visibility, detection and response in a unified solution that helps eliminate pivot between tools while optimizing and scaling security investments.

How it's used

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.
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.
Automatically update assets to stay ahead of attackers See new devices as they connect to your network. Continuously profile assets based on attributes and behavior to uncover threats, compromised devices and shadow IT.

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.

Features QRadar flows

Threats hide within the volume of normal traffic on your network. Get a broad network view across a wide range of network devices.
