In the race to offer comprehensive cybersecurity solutions, the product known as network detection and response (NDR) is a standalone solution as well as a central component of XDR.
Whereas older solutions like antivirus, firewalls, and endpoint detection and response (EDR) have long focused on threats at the network perimeter, the intent of NDR is to monitor and act on malicious threats within organization networks using artificial intelligence (AI) and machine learning (ML) analysis.
Edward Snowden and the NSA breach of 2013, as well as dozens of other nightmares, point to the growing threat of inside threats for a universe of IT environments. Today, both outsiders with the right social engineering skills and disgruntled personnel pose risks to sensitive data when network architectures fail to implement microsegmentation and advanced network traffic analysis (NTA).
This article looks at the top network detection and response solutions in the budding sector, what NDR is, and what to consider in a NDR solution.

Bricata
Launched in 2014, Bricata is another vendor specializing in NDR capabilities and successful enough to catch the attention of OpenText, who acquired the Maryland based vendor in November 2021. While OpenText continues its acquisition spree (notably, acquiring Micro Focus this week), Bricata’s next-generation NDR platform continues to give security administrators visibility into user, device, system, and application behavior inside networks. In addition to real-time context and alerts, Bricata offers clients advanced forensics and threat hunting tools to make the most of investigations and remediation actions.
Bricata Next-Gen NDR Features
- Software-based and hardware agnostic with consumption-based pricing.
- Signature inspection, ML-based malware conviction, and anomaly detection.

Gigamon
Started in 2004, Gigamon has long been in the network visibility game with a portfolio today consisting of traffic intelligence and cloud, network, and data center visibility. Within its network security stack, Gigamon ThreatINSIGHT is the company’s cloud-based NDR solution for high-fidelity adversary detection and response. Evidence of Gigamon’s strength as an NDR solution includes being a connector for almost every other top NDR pick. Their larger technology alliance partners is extensive with 60 of the best vendors for managing network performance, vulnerabilities, and cloud infrastructure.

What is Network Detection & Response?
Network detection and response (NDR) solutions complement tools like EDR and SIEM to analyze and detect malicious network traffic. In the next generation of network traffic analysis (NTA), NDR solutions offer AI and ML-based techniques to evaluate the latest signature-less attacks and unusual traffic patterns. When threats are detected, NDR solutions alert administrators to act or automate pre-configured preventative measures.
NDR Features
- Cognitive modeling to monitor and analyze tactics, techniques, and procedures (TTP).
- Real-time and historical view of traffic for investigating suspicious behavior.
- Context-driven visibility, advanced analytics, and IoC identification for threat hunting.
- Built-in advanced detection with ability to fine-tune configuration management.
- Integration with EDR, SIEM, SOAR, and other network security solutions.
Network Security and NDR
NDR is a complementary network security tool, joining a handful of other critical systems for an enterprise cybersecurity architecture:
- Cloud security
- Endpoint detection and response (EDR)
- Intrusion detection and prevention systems (IDPS)
- Network traffic analysis (NTA)
- Next-generation firewalls (NGFW)
- Security information and event management (SIEM)
- Security orchestration, automation, and response (SOAR)
- User and entity behavior analytics (UEBA)
In 2015, Gartner Research Director Anton Chuvakin introduced the conceptual framework for what would become the “SOC visibility triad”. In a 2020 retrospective, Chuvakin explains how logs (via SIEM), endpoint data (via EDR or XDR), and network data (via NTA and NDR) are critical to security visibility.
How to Choose a NDR Solution
As an emerging security solution, NDR shouldn’t be the first priority for companies building out their cybersecurity infrastructure. That said, the above network detection and response solutions offer plenty for enterprise organizations with well-established cybersecurity postures.
While NDR vendors offer opportunities to bundle other network security tools, including robust portfolios from vendors like Cisco and Sangfor, a top consideration remains ease of integration with existing security systems for SIEM and EDR. Because most organizations aren’t starting from scratch, NDR vendors must strive for interoperability with the leading network security products.
In a crowded marketplace of cybersecurity solutions, NDR is yet another that is on the rise. Only time will tell how niche an audience it will serve. Keep an eye on how the NDR sector evolves in the years to come and whether it survives as a standalone solution and market or gets absorbed by more comprehensive frameworks like XDR.
