TOP SOCs LOOK TO THE NETWORK FIRST

Leading security teams keep a sharp eye on their real-time network threat landscape to spot intruders early. As a visibility and detection solution, Network Detection & Response (NDR) provides almost any SOC with the insights to boost accuracy, improve skills, and close cases faster. Here's how:

COMPREHENSIVE NETWORK VISIBILITY

Modern attackers increasingly favor lateral movement, privilege escalation, and persistence over direct attacks. Elite SOCs rely on NDR to provide unified and comprehensive visibility into network traffic across diverse environments (e.g., hybrid cloud, ICS/OT), especially given the fluid nature of today's networks where users and devices constantly change. By learning normal network behavior patterns, NDR detects anomalies that may reveal early adversary activity, helping SOCs reduce attack escalation risks and protect operations.

CONTINUOUS THREAT HUNTING

Recognizing that every minute an adversary goes undetected can amplify breach impact, elite defenders proactively threat hunt. Guided by hypotheses on their behavior, hunting can discover attackers and shorten their windows of opportunity. Equipped with detailed network data for event context and retrospective visibility using long-term metadata storage, they analyze attacker methods and uncover previously undetected threats.

MULTI-LAYERED DETECTIONS

Inconsistent detection coverage can leave organizations unaware of cybercriminal infiltration. Leading SOCs deploy a robust, multi-layered approach—using targeted signature-based methods for known threats and AI/ML to monitor behaviors and identify unknown, emerging dangers. Leveraging turnkey detection suites, they uncover activity in encrypted traffic, monitor for C2 communications and more to enhance accuracy and drive swift, decisive responses. Crucially, they rely on the network to catch what EDR systems miss.

EXCEPTIONAL FORENSIC DATA

While NDR supplies protocol-rich data to power real-time investigations, it also enables the creation of long-term network archives for retrospective analysis. Zeek®-based platforms deliver compact, standardized data that offers consistent and reliable support across standard SOC analytics tools. For high-impact AI-driven analysis, this data can used by foundational models (which have already been trained on the open-source formats) to explore threat vectors, identify anomalies, and generate additional insights. This empowers teams to hunt for hidden threats, model attacks and scenarios, quickly prepare reports, and improve response plans.

PROTECTING INFRASTRUCTURE

FINANCIAL SERVICES

Financial services SOCs deploy NDR to enhance visibility and monitoring across multi-cloud environments and high-frequency trading networks. By detecting early signs of breaches, uncovering evasive threats, and identifying attempts at data exfiltration, NDR strengthens their cybersecurity posture. Rapid data retrieval and contextual data format also support audit processes, reporting, and activities in support of DORA, NIS2 and other guidelines.

ENERGY

NDR supports utilities, producers, oil and gas refiners, distributors, and other energy sector organizations in defending their infrastructure against rising attacks. By providing SOCs with comprehensive visibility into both IT and OT network traffic, they can better defend against advanced persistent threats (APTs), protect command integrity, and add visibility to systems EDR does not cover.
