ExtraHop NDR Solution: A Revolutionary Advanced Approach in Network Security

Prepared by: Ömer Aydemir – Presales Architect

In today’s rapidly digitalizing world, data security and combating network attacks have become critical concerns. Companies and institutions are implementing various measures to protect their networks and data. In this context, a new technology rapidly gaining popularity in the field of network security is the ExtraHop Network Detection and Response (NDR) solution — a revolutionary approach in threat detection and defense against attacks.

ExtraHop is a cybersecurity company providing AI-driven network intelligence to stop advanced threats across cloud, hybrid, and distributed environments. It was founded in 2007 by Jesse Rothstein and Raja Mukerji in Seattle, Washington, USA.

ExtraHop’s products support on-premises, cloud, multi-cloud, and hybrid environments for network security and performance monitoring. It delivers 360-degree cyber threat visibility and comprehensive situational awareness across the entire hybrid attack surface — from on-premises environments to multi-cloud, distributed workforces, and operations.

What is ExtraHop NDR?

ExtraHop NDR is an advanced network security solution that monitors and analyzes network traffic in real time, identifying threats quickly by detecting abnormal behaviors. While traditional security measures typically rely solely on specific signatures, ExtraHop NDR is designed to provide more effective protection against attacks by utilizing new technologies such as machine learning and artificial intelligence to detect previously unknown threats.

How Does ExtraHop NDR Work?

ExtraHop passively captures network packets by connecting to a network tap, a network switch port configured for monitoring, or using a span/mirror port to analyze traffic. It does not intercept or alter the traffic in any way, providing non-intrusive data collection.

The captured packets are decrypted to extract valuable metadata about network communications, including protocol information, application-level details, and transaction metrics.

ExtraHop NDR analyzes all metadata obtained from the network in real time. The activities of every device and user on the network are recorded and monitored. Machine learning and artificial intelligence algorithms learn normal behavior patterns and determine the network’s “normal” state over time.

Advantages of ExtraHop NDR

Rapid Threat Detection and Response : ExtraHop NDR quickly identifies abnormal behaviors on the network, allowing for immediate intervention in attacks. This minimizes the impact of attacks and enables rapid action.

Comprehensive Visibility : While traditional security solutions typically operate at specific layers, ExtraHop NDR provides comprehensive visibility across all network layers. This allows for complete analysis by monitoring all devices and connections on the network.

Leveraging Artificial Intelligence and Machine Learning : ExtraHop NDR effectively detects threats using artificial intelligence and machine learning algorithms. Additionally, it continuously updates its understanding of the network’s normal behaviors over time.

Threat History and Analysis : ExtraHop NDR records all activities on the network in detail. This enables retrospective analysis of potential attack traces and understanding of the attacker’s actions.

Applications of ExtraHop NDR

ExtraHop NDR has various application areas:

Data Centers : Data centers are critical areas containing sensitive data and services. ExtraHop NDR monitors network traffic in these centers, quickly detecting malicious activities and ensuring the center’s security.

Cloud-Based Services : As organizations increasingly adopt cloud-based services, security risks also increase. ExtraHop NDR effectively detects threats in cloud environments and provides security measures.

Insider Threats : Some threats originate internally and can be challenging for traditional security measures to detect. ExtraHop NDR monitors insider threats as well, providing timely intervention opportunities.

ExtraHop NDR has ushered in a new era in network security by overcoming the limitations of traditional security solutions. With features such as real-time monitoring, artificial intelligence, and machine learning, it detects unknown threats and secures networks more effectively.
