The most advanced NDR solution, powered by Self-Learning AI

Integrating Network Detection and Response (NDR) tools with other cybersecurity solutions enhances an organization’s threat detection and response capabilities. NDR tools monitor network traffic to identify suspicious activities and patterns, making them an excellent complement to Endpoint Detection and Response (EDR) and Security Information and Event Management (SIEM) systems. NDR helps to fill the gaps left by EDR, expanding visibility from individual devices to network-wide threats, offering a broader perspective on attacks that may bypass traditional endpoint defenses.

NDR tools can also be integrated with firewalls to provide enriched threat intelligence and respond to network threats. When unusual traffic patterns or network anomalies are detected, NDR can alert the firewall, which may then block or restrict access based on predefined rules. Additionally, NDR integrates well with SIEM systems, feeding network-level data into the SIEM for centralized monitoring and comprehensive analysis of potential threats across an organization. By combining these technologies, security teams gain holistic visibility and can correlate data from various sources for a stronger defense against multi-stage attacks.

The effectiveness of an NDR solution is measured by its ability to provide early and accurate detection of threats, enable rapid and effective incident response, and reduce the overall risk to your organization.
Focus on whether a platform provides complete visibility across your on-premise, virtual, cloud, and hybrid networks, including remote worker endpoints, OT devices, and ZTNA. Also, consider its effectiveness in reducing alert fatigue and improving your security posture.
There are several useful evaluation methods, such as live traffic analysis. Can you analyze real-time network traffic and detect anomalous behavior? Look for demonstrations of the tool's abilities to detect subtle indicators of compromise that bypass traditional security controls. Also, conduct simulated attacks to evaluate the system's detection and response capabilities against various adversaries and scenarios.
Consider alert prioritization and enrichment too. Does the platform prioritize security alerts based on severity and potential impact? Look for features that automatically enrich alerts with contextual information to aid in investigation.
To streamline workflows and enhance incident response, evaluate the tool's ability to integrate with your existing security infrastructure, including SIEM and SOAR platforms. Finally, assess the NDR platform's effectiveness in improving analyst workflow efficiency. Look for features that automate tasks and reduce manual effort. The platform should also provide actionable insights so teams can move from a reactive to a proactive security posture.

Most NDR vendors on the market and traditional solutions such as Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS) rely on detecting known attacks with historical data such as external threat intelligence, signatures and detection rules, leaving organizations vulnerable to novel threats. This legacy approach to threat detection means that at least one organization needs to fall victim to a novel attack before it is formally identified. It also produces a vast number of false positives, since most vendors apply models that are trained globally and are not specific to a particular organization or the context of their unique environment. 
When choosing an NDR solution, it’s essential to evaluate specific features that enhance network visibility, threat detection, investigation and response capabilities. Some organizations can benefit from NDR solution that use anomaly detection  and AI, enabling detection of abnormal network behavior. Darktrace / NETWORK uses multi-layered AI to learn what is normal behavior for your organization, detecting any activity that could cause business disruption, and autonomously responds to both known and previously unseen threats in real time. 
Another key feature is integration with other cybersecurity tools, such as SIEM, EDR, and firewalls. This compatibility ensures that the NDR solution can feed valuable data into a centralized system, providing a comprehensive view of potential threats across the organization. Additionally, autonomous response capabilities are crucial for reducing the total damage and dwell time of an attack. Some autonomous response solutions, like Darktrace / NETWORK, can take immediate action without causing business disruption, these actions include isolating infected devices, forcing a user to reauthenticate, or blocking suspicious IP addresses.
An NDR solution should also offer scalable architecture to support growing network environments, along with real-time alerting and detailed forensic capabilities. These allow security teams to investigate incidents thoroughly and trace the origin of attacks. Unlike chat or prompt-based LLMs that create static incident summaries, Darktrace’s Cyber AI Analyst continually analyzes and contextualizes every relevant alert in your network, autonomously forming hypotheses and reaching conclusions just like a human analyst would, saving your team a significant amount of time and resources. 

NDR (Network Detection and Response) and EDR (Endpoint Detection and Response) serve complementary roles in cybersecurity, but they focus on different areas. NDR tools monitor network traffic to detect threats that traverse or originate within the network, such as lateral movement by malicious actors. In contrast, EDR focuses on endpoints—such as laptops, servers, and mobile devices—detecting suspicious activities at the device level, such as unauthorized file modifications or unusual program executions.

While EDR is adept at identifying threats targeting individual endpoints, NDR provides a broader perspective, focusing on network-wide patterns and behaviors. For example, an NDR tool can detect an attacker moving across the network or attempting to establish command-and-control communications. When combined, NDR and EDR offer a more comprehensive defense, with NDR handling network-level anomalies and EDR focusing on endpoint-specific threats.

NDR (Network Detection and Response) and NTA (Network Traffic Analysis) both monitor network traffic, but they differ in functionality and purpose. NTA tools primarily focus on passive monitoring and analysis of network traffic to help detect unusual patterns, and performance-related issues, while NDR is focused on security and adds a response capability. NTA systems can detect anomalies in network traffic but typically do not provide automated response capabilities, which is what NDR solutions are designed to do.

NDR and SIEM (Security Information and Event Management) serve distinct but complementary functions in cybersecurity. NDR tools focus specifically on analyzing and responding to network traffic, providing deep insights into network-based threats like lateral movement or abnormal traffic flows. SIEM systems, on the other hand, aggregate and analyze data from multiple sources, including network traffic, endpoints, and applications to provide a centralized view of an organization’s security posture.

Conventional approaches mainly rely on predefined patterns to identify known threats. Signature-based systems can be effective at blocking established malware and known attack techniques, but they are limited in their ability to detect novel or sophisticated threats that have not been previously encountered. This limitation leaves organizations vulnerable to zero-day exploits, advanced persistent threats (APTs), and other evasive attacks that deliberately circumvent known signatures and security protocols.

NDR takes a more proactive and adaptive approach. It continuously monitors network traffic and analyzes behavior patterns, identifying anomalous activity that may indicate an unknown threat. Unlike purely signature-based systems, NDR also employs behavioral analysis, learning what constitutes "normal" behavior for every user, device, and network segment within your environment. It then automatically detects even subtle deviations from that continually updated baseline, providing real-time intelligence on these and other potential threats.

For instance, zero-day exploits, which leverage previously unknown vulnerabilities, are revealed by the unusual network communication or resource access they initiate, even before signatures exist. APTs, characterized by their sophisticated, low-and-slow tactics, are uncovered through the cumulative effect of small, unusual behaviors that deviate from established norms. Insider threats, stemming from malicious or negligent actions by authorized users, become evident when a user's activity strays from their typical operational profiles. Evasive malware, designed to bypass traditional, signature-based security controls, cannot hide its network-level interactions, allowing NDR to detect its presence.
