For many organisations, Endpoint Detection and Response (EDR) has become the primary monitoring source used by their Security Operations Center (SOC) providers. Modern EDR platforms deliver valuable visibility into endpoint activity, detect malicious processes, and enable rapid response actions across workstations and servers.
However, relying solely on EDR is becoming an increasingly risky security strategy.
As cyber threats continue to evolve, infrastructures become more distributed, and organisations generate unprecedented levels of network traffic, security teams need broader visibility than endpoint monitoring alone can provide. The reality is simple: if your SOC only monitors endpoints, significant security visibility gaps remain across your environment.
Even more concerning, attackers are increasingly targeting the very tools defenders rely on. The rise of EDR bypasses and EDR-killer techniques means organisations must assume endpoint visibility may be degraded or completely removed during a sophisticated attack.
This is why modern security teams are investing in Network Detection and Response (NDR) solutions, AI-driven NDR platforms, and autonomous network detection and response capabilities to complement endpoint security and create a more resilient security posture.
The Visibility Problem: Why EDR Alone Cannot See Everything
EDR provides visibility into systems where agents are installed. While this delivers valuable endpoint intelligence, it does not provide comprehensive visibility across modern enterprise environments.
Today’s organisations rely on a diverse ecosystem of assets, including:
- Network devices
- IoT systems
- Printers and industrial equipment
- Cloud workloads
- Containers and Kubernetes environments
- Third-party managed systems
- Shadow IT assets
- Legacy infrastructure where agents cannot be deployed
If an asset cannot run an EDR agent, it effectively becomes invisible to an EDR-only SOC.
Attackers understand this limitation and frequently target unmanaged systems as entry points, pivot locations, or command-and-control infrastructure. Even systems with EDR installed cannot guarantee continuous visibility throughout an attack. Modern adversaries actively attempt to disable, bypass, tamper with, or blind endpoint security tools before executing their objectives.
This creates dangerous security visibility gaps that can prevent analysts from detecting critical stages of an attack.
The Network Never Lies
While endpoint visibility is limited to managed devices, network detection and response provides a broader view of communications occurring across the entire environment.
Every lateral movement attempt, data transfer, DNS query, beacon, cloud connection, and command-and-control communication leaves evidence on the network.
Modern enterprise NDR platforms provide organisations with the ability to answer critical security questions:
- Which systems are communicating?
- What protocols are being used?
- Where is sensitive data flowing?
- Are unusual connections occurring?
- Is there evidence of command-and-control activity?
- Are assets communicating with known malicious infrastructure?
- Are cloud and on-premises workloads behaving normally?
Unlike endpoint agents, network telemetry cannot simply be uninstalled from a compromised system. Attackers may disable EDR, but they still need to communicate across the network to achieve their objectives.
This is where AI-driven NDR platforms provide a critical advantage by continuously analysing network behaviour and identifying suspicious activity in real time.
Modern Threats Actively Target EDR
One of the most significant developments in recent years has been the widespread adoption of EDR-killer techniques by ransomware operators and advanced threat groups.
Many attackers now include dedicated phases within their attack playbooks designed to disable security products before launching encryption, data theft, or destructive actions.
Common techniques include:
- Exploiting vulnerable drivers to terminate security processes
- Disabling endpoint agents through administrative access
- Tampering with security services
- Leveraging kernel-level tools to bypass protections
- Abusing legitimate operating system functionality to evade detection
The objective is straightforward: eliminate the defender’s visibility before executing malicious actions.
If a SOC relies exclusively on endpoint telemetry, a successful EDR bypass can leave analysts blind at the exact moment visibility is needed most.
This creates a dangerous single point of failure.
When endpoint visibility disappears, what remains?
For organisations deploying NDR security solutions and autonomous network detection and response capabilities, the answer is clear: the network.
Even after EDR has been disabled, attackers continue generating observable network activity through reconnaissance, lateral movement, command-and-control communications, and data exfiltration. These behaviours remain visible through network telemetry and often become the only reliable source of detection during the later stages of an attack.
EDR Tells You What Happened. NDR Tells You What Else Happened.
A mature SOC should never view endpoint security and network monitoring as competing technologies.
They answer different questions.
EDR excels at:
- Process visibility
- File activity monitoring
- User actions
- Registry changes
- Endpoint containment and response
Network Detection and Response excels at:
- Asset discovery
- Lateral movement detection
- Command-and-control identification
- Data exfiltration monitoring
- Detection of unmanaged devices
- Hybrid cloud visibility
- Detection when endpoint controls have been disabled
- Real-time threat detection across the entire network
When combined, they provide a complete picture of the attack lifecycle.
An EDR alert may identify malware execution on a server. An AI-driven NDR platform can immediately reveal every system that communicated with that server before, during, and after the incident.
Likewise, if endpoint telemetry suddenly disappears from a critical asset, network monitoring can continue providing visibility into its behaviour and determine whether the loss of telemetry itself is indicative of malicious activity.
This level of correlation dramatically reduces investigation times while improving response accuracy and confidence.
The Growing Importance of Data Center Monitoring and Unified Network Observability
As organisations expand their hybrid infrastructure, data center monitoring, data center monitoring solutions, and data center security monitoring have become critical components of modern SOC operations.
Traditional security tools often struggle to provide visibility across data centres, cloud environments, branch offices, and remote workforces simultaneously.
Modern NDR solutions address this challenge through unified network observability, enabling security teams to monitor network behaviour, asset communications, performance metrics, and threat activity from a single platform.
By combining security monitoring with operational visibility, organisations gain deeper insight into both threats and infrastructure performance.
AI SOC Automation and Autonomous Threat Mitigation
Security teams are increasingly overwhelmed by alert volumes, staffing shortages, and expanding attack surfaces.
This is driving rapid adoption of AI SOC automation capabilities within modern NDR platforms.
Advanced autonomous network detection and response solutions leverage machine learning and behavioural analytics to:
- Continuously analyse network traffic
- Detect previously unseen threats
- Reduce false positives
- Prioritise high-risk incidents
- Accelerate investigations
- Enable autonomous threat mitigation
Rather than relying solely on manual analyst intervention, AI-powered systems can identify suspicious activity, correlate telemetry across multiple sources, and initiate containment actions significantly faster than traditional workflows.
This allows SOC teams to focus on high-value investigations while improving overall detection and response effectiveness.
Building a Complete Modern SOC
The question should never be:
“EDR or network monitoring?”
The question should be:
“How do we combine endpoint and network visibility to eliminate security visibility gaps?”
Organisations relying exclusively on EDR are making security decisions based on a partial view of their environment while placing significant trust in a technology that attackers increasingly target during intrusions.
A modern SOC requires five foundational capabilities:
- Endpoint visibility
- Network telemetry and NDR security
- Cloud observability
- Threat intelligence
- Advanced analytics, AI, and automation
Only by combining these data sources can defenders achieve the level of visibility necessary to detect sophisticated threats and respond effectively.
Conclusion
If your SOC only sees endpoint activity, it is missing a substantial portion of the attack surface and risks losing visibility entirely if endpoint controls are compromised.
Network Detection and Response (NDR) closes these security visibility gaps, provides critical context for investigations, and ensures defenders maintain visibility even when attackers attempt to disable endpoint security tools.
By combining endpoint telemetry, enterprise NDR, data center security monitoring, unified network observability, real-time threat detection, and AI SOC automation, organisations can build a resilient and modern security operations capability.
In today’s threat landscape, an EDR-only SOC is not a modern security strategy—it is an incomplete one. The most effective security operations centres combine endpoint and network visibility through AI-driven NDR platforms and autonomous threat mitigation to create a detection capability that attackers cannot easily evade, disable, or bypass.
