Modern networks are business-critical. As infrastructure grows in scale and complexity, having accurate, real-time visibility into network traffic is essential for maintaining performance, availability, and security.
FastNetMon provides high-performance network traffic visibility using flow-based monitoring. By analysing traffic metadata from routers, switches, and virtual infrastructure, FastNetMon helps network and security teams understand traffic behaviour, detect anomalies early, and respond quickly to incidents such as DDoS attacks.
Rather than relying on packet payload inspection, FastNetMon focuses on scalable, efficient traffic analysis that works reliably at very high speeds and across diverse network environments.
Flow-Based Network Traffic Visibility
Network traffic visibility is the ability to observe and analyse how traffic moves through your network — who is communicating, over which protocols, at what rate, and for how long.
FastNetMon builds this visibility using industry-standard telemetry sources such as NetFlow, IPFIX, sFlow, and port mirroring. These technologies provide detailed traffic metadata without introducing latency or requiring specialised hardware.
This approach allows FastNetMon to deliver consistent visibility across physical networks, virtualised environments, and cloud infrastructure while remaining lightweight and highly scalable.
Reduce Network Blind Spots
Hybrid architectures, cloud deployments, and rapidly changing traffic patterns often create blind spots that limit effective monitoring.
FastNetMon integrates directly with existing network devices and collects flow data from multiple sources simultaneously, creating a unified view of network traffic. This makes it easier to identify unexpected traffic spikes, abnormal protocol usage, or unusual traffic sources that may indicate misconfigurations, performance issues, or active attacks.
By analysing traffic patterns in real time, FastNetMon helps teams detect problems early — before they escalate into outages or security incidents.
Real-Time and Historical Traffic Analysis
FastNetMon provides immediate insight into current network conditions while also maintaining long-term historical traffic data. This combination supports both day-to-day operations and post-incident investigation.
Real-time monitoring enables fast detection of anomalies such as sudden increases in bandwidth usage or packet rates. Historical data allows teams to compare current traffic against baselines, analyse previous incidents, and refine detection thresholds over time.
Traffic data is stored in a high-performance, column-oriented ClickHouse database, enabling efficient querying and long-term retention even in high-volume networks.
Reporting, Metrics, and Integrations
FastNetMon enables flexible analysis of traffic data using SQL-based queries. Network engineers can generate custom reports to understand traffic distribution, identify top talkers, or investigate specific hosts, subnets, or protocols.
The platform also exports metrics to popular time-series databases such as ClickHouse, InfluxDB, Graphite, and VictoriaMetrics. These metrics include bandwidth, packet rates, and flow counts at host or network level, making it easy to integrate FastNetMon into existing monitoring and observability stacks.
This openness allows teams to build custom dashboards, automate alerts, and connect traffic visibility directly to operational workflows.
Traffic Visibility as the Foundation for DDoS Protection
Effective DDoS detection depends on accurate traffic visibility. FastNetMon continuously monitors traffic behaviour and identifies attacks based on abnormal changes in volume, packet rates, and flow characteristics.
This flow-based approach allows FastNetMon to detect both large volumetric attacks and lower-volume anomalies that may evade traditional threshold-based monitoring. Stored traffic data also supports post-attack analysis, helping teams improve detection logic and mitigation strategies over time.
By combining traffic visibility with automated DDoS detection and mitigation, FastNetMon provides a complete, network-level view of security and performance.
Built for Scale and Performance
FastNetMon is designed for environments where scale matters. Its high-performance processing engine and efficient storage architecture allow it to operate reliably in enterprise, service provider, and cloud networks without artificial limits on traffic volume or monitored devices.
Whether you need visibility across a single network segment or a multi-terabit backbone, FastNetMon scales with your infrastructure.
