Solutions for network anomaly detection

Network anomaly detection does not depend on alerts alone, but on context to tell a recurring bottleneck or an operational failure apart from behaviour that may signal an incident.
The decisive point is the correlation between performance and traffic, because availability on its own rarely explains what changed and where the degradation started.
When the team follows performance metrics only, it tends to identify how the problem shows up before understanding its origin. When it watches flow alone, it can see volume and conversations between assets, but may still miss the real impact on services, latency and user experience.
Reading both together increases visibility and speeds up prioritization, because the team starts to see relationships, which helps identify deviations before the problem escalates.
Why network anomaly detection requires correlation, not isolated readings
An anomaly is not a synonym for an outage. In many cases the network is still up, yet already shows signs of degradation, abnormal bandwidth consumption, unusual lateral conversation between assets or behavioural deviation in critical applications.
Without correlation, the technical team receives fragments of the problem. With correlation, it starts to see relationships.
What performance shows before the break
Network Performance Monitor (NPM) was designed to track network health, availability and performance, and to provide path analysis and data correlation in complex environments.
In practice, the team begins to identify latency swings, saturation and performance loss at early stages. That means noticing rising latency, slower responses, behavioural change in segments and signs of saturation that have not yet turned into a full outage. For management, this gain reduces reactive response and improves decision time.
What traffic reveals while availability still looks normal
NetFlow Traffic Analyzer (NTA) adds a decisive layer, because it shows bandwidth usage by application, protocol and IP group, and collects flow data from different vendors and virtualized environments. That helps identify bottlenecks, trends and traffic changes that would go unnoticed in more basic dashboards.
This matters because many incidents start as a change of pattern, not as an abrupt drop. When the team can see who consumes the most resources, who started talking to whom and which flows changed unexpectedly, the investigation gains speed and precision.
How network anomaly detection changes when NPM and NTA work together
With them combined, the investigation stops depending on fragmented analysis, shortening the time needed to locate the origin, impact and propagation of the anomaly.
In this model, features such as PerfStack help correlate bandwidth, latency and other indicators in a single interface. That makes deviation analysis easier and speeds up identifying what really changed in the environment.
Network Performance Monitor to locate where degradation begins
Network Performance Monitor helps answer structural questions. Which segment started to degrade, which devices were affected, which path is getting worse and how the change spreads across the topology. That reading is essential to avoid generic analysis and cut the time spent on unhelpful hypotheses.
For leadership, this has a direct effect on cost and continuity. The earlier the technical origin is isolated, the lower the chance of escalating teams unnecessarily, opening the wrong tickets or investing in fixes that do not address the main cause.
NetFlow Traffic Analyzer to understand who creates the deviation and how it spreads
NetFlow Traffic Analyzer deepens the reading by analysing flows, applications, protocols and bandwidth usage in real time. It also gives visibility over east-west traffic in virtualized environments, which helps monitor internal movement and problems tied to traffic between virtual machines.
That level of detail is especially useful when the anomaly may be operational or malicious in origin. A bandwidth spike, an out-of-pattern lateral conversation, a device that stops sending flow data or an abrupt traffic increase can be the start of serious degradation or of suspicious behaviour.
What network anomaly detection lets you see before the escalation
When correlation works, the company stops acting only after the impact. This reduces operational impact, avoids unnecessary escalations and improves the continuity of critical services.
Operational incidents that start small
Many operational incidents start with modest signals, such as growing latency, irregular bandwidth usage, intermittent failures in one segment or degradation in an application that depends on the network. In isolation, those signals look manageable. Correlated, they show a worsening trend.
This capability improves troubleshooting, capacity planning and prioritization. Instead of responding to the noisiest alert, the company starts deciding based on real impact, likely origin and how fast the deviation is spreading.
Suspicious behaviour and attacks before the bigger damage
Not every anomaly is an attack, but attacks usually produce anomalies. In security scenarios, this behaviour can indicate lateral movement, misuse of resources or unusual communication attempts between assets.
Correlating performance and traffic therefore broadens the value of observability, providing more operational context to prioritize critical incidents and reduce prolonged impact.
How AKEN applies network anomaly detection
AKEN brings together solutions and services that help broaden visibility over the environment and reduce fragmented readings of network events.
With Network Performance Monitor (NPM), it is possible to track infrastructure performance, availability and behaviour with more precision.
NetFlow Traffic Analyzer (NTA), in turn, deepens traffic analysis, making it easier to understand bandwidth consumption, flows, patterns and relevant deviations.
This work can be reinforced with AKEN Watch, which offers continuous monitoring for environments that require closer follow-up, and with the Observability Journey, focused on implementing and managing a more data-driven operation.
Network anomaly detection in your company should not depend on isolated interpretations. Count on more context to support response, prevention and planning.
Frequently asked questions on the topic
1. What is network anomaly detection?
It is the ability to identify behaviour outside the expected pattern on the network, such as traffic deviations, performance degradation, latency changes and signals that may indicate incidents or attacks.
2. What is the difference between NPM and NTA?
NPM monitors network health, availability, topology and performance. NTA deepens the analysis of traffic, bandwidth, protocols, applications and flows between assets.
3. Why correlate performance and traffic?
Because performance shows where the service degrades, while traffic helps explain who created the deviation, how it propagated and the likely impact on the operation.
4. Does network anomaly detection only help with troubleshooting?
No. It also helps anticipate bottlenecks, plan capacity, adjust bandwidth policies, improve prioritization and recognize suspicious patterns before greater damage occurs.
5. How does AKEN support this scenario?
AKEN brings together specialized solutions and services to broaden visibility, reduce operational noise and speed up the response to relevant deviations.
