As organisations rely more on their networks than ever before, network traffic visibility has become essential to protect business operations and defend against cyber threats.

While modern network technology has enabled huge efficiencies and new functionality, it also creates risk—networks face innumerable threats aiming to disrupt or damage infrastructure. At the same time, networks face a host of new challenges, including growing data volumes, an increasingly diverse IoT (Internet of Things), and more complex and integrated network topologies.

This guide explains why network traffic visibility is so important, the cybersecurity and operational benefits it provides, and how your organisation can improve visibility and protect its digital assets.

Blind Spots Hinder Network Traffic Visibility

While fine-grained network visibility can address these challenges, monitoring is hindered by the same obstacles it’s meant to solve. In a study by Vanson Bourne, 67% of organisations said network blind spots are the biggest obstacle to protecting their data.

Traditionally, WANs relied on a combination of Security Information and Event Management (SIEM) solutions and network management systems for visibility. However, lack of mobile device support and disparate security policies and protocols between various cloud endpoints, platforms, and applications make it nearly impossible to implement a unified network visibility solution.

What is Network Traffic Visibility?

Network traffic visibility is the ability to monitor, analyse, and act on network traffic in real time. Through a detailed picture of incoming and outgoing traffic, a network monitoring tool helps organisations identify threats and gives administrators insights to manage networks more efficiently.

Network visibility also helps uncover suspicious behaviour that may indicate malicious attempts to access or disrupt services. With deep packet analysis, network teams can view headers, payloads, and other metadata associated with every data packet, allowing them to proactively uncover and block malicious traffic.

A quality network monitoring tool provides various capabilities to support prompt threat detection and mitigation. These include:

Capturing data from multiple sources
including NetFlow, IPFIX, and sFlow traffic monitoring.
Integration with all network hardware
e.g., switches, routers, etc.
Storage for current and historical data
often running to terabytes and even petabytes.
Comprehensive reporting
and querying capabilities.
Automation and custom rules
to support efficient threat detection and mitigation.

Network Traffic Visibility Makes You More Secure

FastNetMon isn’t just a DDoS detection solution—it also provides real-time and historical network traffic visibility. Integrating seamlessly with all common network hardware, it gathers network activity data from various sources, including NetFlow, IPFIX, and sFlow traffic monitoring.

Combining state-of-the-art DDoS detection and mitigation with real-time network monitoring, FastNetMon supports security and network teams to uncover the most sophisticated cyber threats. Top features include:

1) Fast threat detection

Network visibility helps you swiftly detect and prevent malicious activity, such as unauthorised data exfiltration—preventing costly data breaches. To spot malicious activity, you can use a network traffic analysis tool to detect anomalous or suspicious network traffic flowing to or from devices.

2) Shed light on blind spots

Modern business networks are large and complicated. Digital transformation, hybrid cloud infrastructure, and remote workforces have made network monitoring a tough task—and this creates risk. A powerful network monitoring tool sheds light on blind spots and helps network and security teams uncover anomalous or suspicious activity no matter where it occurs.

3) Cybersecurity Compliance

Industry frameworks such as NIST Cybersecurity Framework (CSF) require effective network monitoring and visibility. In its report Security and Privacy Controls for Information Systems and Organizations, NIST recommends the use of networking monitoring to detect:

  1. Cyber threats and indicators of attack
  2. Unauthorised local, network, and remote connections

4) Optimise network performance

As network complexity rises, configuration issues can harm performance, reducing operational efficiency and harming customer experience. Full network traffic visibility helps organisations uncover and address misconfigurations, bottlenecks, inactive hosts, and other network issues, enabling higher network performance and avoiding costly slowdowns and downtime.

5) DDoS Protection

Network traffic visibility helps security and network teams quickly detect and mitigate DDoS attacks before they disrupt business or customer activities. For example, large and unexplained spikes in traffic to specific network IPs can indicate a volumetric DDoS attack. By quickly recognising spikes, security and network teams can mitigate attacks and prevent them from disrupting operations.

How Does Network Observability Prevent DDoS Attacks?

Not all DDoS attacks are obvious. A powerful network monitoring tool ingests the full spectrum of network data and supports custom-written detection and mitigation rules. FastNetMon’s network traffic analysis tool protects against sophisticated DDoS attacks by helping your organisation:

Detect Attacks Quickly
Early detection and mitigation of a DDoS attack is critical. FastNetMon detects suspicious traffic patterns in real time, enabling you to protect your network and avoid costly disruptions.
Uncover Low-Volume Attacks
Many DDoS attacks are short-term assaults with limited volumes—too small to trigger volume-based mitigations but still harmful. FastNetMon makes it easy to set alerts and thresholds to monitor for even the stealthiest attacks.
Understand Traffic Sources
Knowing where network traffic comes from is essential. With FastNetMon, organisations can collect and study context-specific information such as geolocation data and set policies to alert against any suspicious activity in embargoed countries or unusual sources.
Monitor Network Flow
Go beyond basic SNMP data to get the full context of network activity. Flow data monitoring provides deep insights such as where attacks originate and what IP addresses, ports, and protocols they use, supporting more granular filters to prevent future attacks.
Manage Mitigation Policies
As attackers become more sophisticated, DDoS attack patterns are becoming harder to spot. FastNetMon makes it easy to uncover trends in past incidents that could signal an attack. These insights inform automated detections and mitigations, ensuring prompt remediation of future DDoS attacks.
