Challenges
Alerts Are Not Enough
Across hybrid infrastructure, east–west traffic, and encrypted communications, critical network activity often goes unseen.
Security tools may generate alerts, but alerts alone rarely provide the evidence needed to understand what actually happened. Analysts still need to validate events, determine scope, and reconstruct how an attack unfolded across systems and network segments.
Effective Network Detection and Response depends on more than signal generation. It requires deep network visibility, packet-grounded evidence, and the ability to investigate activity before, during, and after an event so security teams can move from alert to confident response.
Outcomes That Matter
See More and Validate with Confidence
Validate Suspicious Activity Faster
Alerts rarely provide enough context to confirm real threats. Packet-grounded evidence helps analysts quickly validate suspicious activity and prioritize investigations.
See East–West and Hybrid Traffic More Clearly
Broader network visibility exposes suspicious activity across internal segments, cloud environments, and encrypted communications where lateral movement often occurs.
Investigate and Scope Incidents More Efficiently
Network evidence helps analysts reconstruct timelines, determine incident scope, and understand how suspicious activity moved across systems and network segments.
NETSCOUT’s Solution and How It Delivers Value
Network Intelligence for Improved Security Operations
Omnis Cyber Intelligence is a Deep Packet Inspection (DPI)-based Network Detection and Response platform that analyzes traffic directly from packets using distributed sensors at the source of collection. This architecture performs analytics close to the traffic while preserving packet-grounded evidence for investigation.
For Network Detection and Response, this approach delivers value in three key ways.
- Improves visibility into suspicious activity using multiple detection methods, including indicators of compromise, signatures, policy violations, attack surface changes, and behavioral baselining.
- Provides packet-grounded evidence and historical context, independent of detections, so analysts can validate alerts, reconstruct timelines, and understand how activity moved across systems and network segments.
- Integrates with existing SIEM, XDR, SOAR, and EDR platforms, enriching those workflows with deeper network context so investigations can begin in the tools teams already use.
The result is a Network Detection and Response approach designed not only to detect suspicious behavior, but to help analysts investigate events faster and respond with greater confidence.

FAQs
Frequently Asked Questions
What is network detection and response?
Network detection and response is a security approach focused on identifying suspicious activity in network traffic and helping teams investigate, validate, and respond to threats using network-derived evidence. Unlike approaches that stop at alerting, NDR helps analysts understand what happened and determine scope with greater confidence.
How is Omnis Cyber Intelligence different from other NDR approaches?
Omnis Cyber Intelligence combines analytics at the source of packet capture with always-on historical evidence and investigation workflows. That gives teams packet-grounded context to validate threats, investigate retrospectively, and understand activity across east-west, hybrid, and cloud environments.
Why does packet-grounded evidence matter for NDR?
Alerts alone do not always provide enough context to determine whether suspicious behavior actually occurred, how it unfolded, or what systems were involved. Packet-grounded evidence helps analysts validate findings, reconstruct timelines, and reduce ambiguity during investigations.
Does Omnis Cyber Intelligence replace our SIEM, XDR, SOAR, or EDR tools?
No. Omnis Cyber Intelligence is designed to amplify the existing security ecosystem. Through integrations, it enriches third-party workflows with packet-grounded context so teams can investigate from the tools they already use and bring in deeper network evidence when needed.
Can Omnis Cyber Intelligence support retrospective investigation if a detection was missed?
Yes. Omnis Cyber Intelligence preserves historical evidence that allows analysts to investigate activity before, during, and after an alert was triggered. This supports retrospective analysis when the original signal was weak, incomplete, or never triggered at all.
How does Omnis Cyber Intelligence scale across large or distributed environments?
Omnis Cyber Intelligence uses distributed sensors and performs threat analytics at or near the source of packet capture rather than depending entirely on a centralized analytics tier. This supports scalable visibility and investigation across large enterprise environments.
