The landscape of cyber threats continues to advance rapidly, compelling organizations across various sectors to revamp their cybersecurity strategies. Attackers are now employing sophisticated methods such as encryption, living-off-the-land tactics, and lateral movements to bypass traditional defenses, causing damage long before detection is possible. Moreover, even after identifying an incident, security teams face challenges proving to regulators that all vulnerabilities have been fully remediated.
While endpoint detection and response (EDR) solutions remain essential, attackers have adapted by evading these host-focused protections. This is especially problematic for the financial services, energy and utilities, transportation, and government sectors that often operate proprietary systems, unique protocols, or face strict regulatory mandates demanding comprehensive visibility and mitigation proof.
In response, leading security teams are leveraging network detection and response (NDR) — a strategy that provides an immutable, ground-truth record of all network activity. This enables proactive threat hunting, real-time anomaly detection, and definitive compliance evidence.
Financial Services: Guarding Precious Data Against Invisible Threats
As the most targeted industry worldwide, financial institutions manage highly sensitive data and operate under intense regulatory scrutiny. NDR plays a critical role in detecting unauthorized data access, safeguarding ultra-fast transactions, and ensuring compliance.
Spotting Stealthy Data Theft
Attackers in finance often aim to stay under the radar while exfiltrating valuable information, sometimes for months on end through encrypted channels. NDR helps identify suspicious patterns and subtle anomalies that traditional tools like SIEM and EDR might miss, such as slow, encrypted data leakage during routine business hours.
Securing High-Speed Trading
High-frequency trading demands zero latency; traditional inline security tools or endpoint agents are impractical. NDR’s passive network monitoring introduces no latency, analyzes proprietary protocols, and uses microsecond-precision timestamps to detect subtle market manipulation attempts effectively.
Ensuring Regulatory Confidence
With evolving compliance standards like DORA, NIS2, and FINRA rules, financial firms must maintain airtight audit logs and demonstrate effective incident response. NDR solutions provide continuous monitoring and detailed forensic evidence that satisfy these regulator expectations.
Energy & Utilities: Closing IT/OT Security Gaps
The energy sector, managing critical physical infrastructure, is a prime target for cyberattacks, including recent examples like Volt Typhoon. Traditional endpoint protections cannot secure many operational technology (OT) systems, urging organizations to expand defenses with network-based monitoring as mandated by regulations such as FERC Order No. 887.
Detecting Early Reconnaissance
Advanced attackers conduct long reconnaissance phases before strikes. NDR detects suspicious scanning and enumeration of critical energy infrastructure, highlighting risks before exploitation.
Monitoring IT/OT Traffic
Because most OT devices cannot run endpoint security agents and often rely on simple passwords for emergency access, NDR focuses on monitoring traffic between IT and OT zones to detect pivot attempts and anomalous communications.
Identifying Industrial Control Anomalies
By analyzing industrial protocols such as Modbus, NDR can flag abnormal commands that could jeopardize operational safety, such as unauthorized speed adjustments in turbine controls, allowing preemptive threat mitigation.
Transportation: Protecting Complex, Connected Networks
The transportation sector’s increasing interconnectedness exposes broader attack surfaces, threatening supply chains and operational integrity. NDR offers vital visibility here by monitoring fleet and control system communications.
Securing Fleet and Signaling Systems
NDR tracks real-time exchanges involving GPS, routing, and emergency signals, detecting unauthorized navigation commands, GPS spoofing, or autopilot manipulations, enabling faster defensive responses.
Protecting Passenger Data & Payments
With enormous volumes of sensitive passenger and payment data, transportation firms benefit from behavioral analytics within NDR platforms that spot anomalous access and data harvesting.
Preempting Operational Disruptions
NDR monitors specialized protocols governing signaling, air traffic control, and traffic management to detect and block malicious attempts aimed at disrupting critical physical operations, minimizing catastrophic risks.
Government: Combating Persistent, Nation-State Threats
Government agencies face relentless advanced persistent threats (APTs) targeting classified data and complex environments. Compliance with frameworks like NIST 800-53, CMMC, and FISMA is mandatory, with NDR supporting these efforts by uncovering subtle indicators of long-term breaches and data theft.
Uncovering Persistent Intrusions
NDR’s continuous monitoring reveals anomalies such as unauthorized lateral movements using valid credentials — critical in the zero trust security model, which assumes breach and requires constant verification.
Advancing Zero Trust Compliance
Federal mandates push for zero trust architectures by the end of fiscal year 2024. NDR provides foundational visibility, real-time network monitoring, and eliminates traditional security blind spots vital to zero trust implementations.
Supporting Attack Attribution
For national security, attributing attacks to specific adversaries is key. NDR collects rich forensic data on tactics, techniques, and procedures (TTPs), aiding analysts in linking incidents to known threat actor profiles.
Shared Insights Across Industries
- Network as Ground Truth: Network traffic provides an immutable, trustworthy record that attackers struggle to tamper with.
- Layered Security Integration: NDR complements EDR and SIEM tools, creating a multi-faceted defense capable of identifying diverse threats.
- Encrypted Traffic Monitoring: As encryption saturates network traffic, NDR’s capability to analyze encrypted communications without decryption is invaluable.
- Legacy & Proprietary Systems Support: NDR effectively monitors systems where endpoint agents cannot be deployed due to operational or technical constraints.
