What ntop can do for you
Bandwidth Monitoring Monitor network traffic in real time using flow-based technologies or analysing traffic mirrors to ensure optimal performance and detect congestions or anomalies. Also collect from NetFlow or sFlow exporters.
Observability Measure network and application performance metrics, detect performance degradation, high-latency paths, or packet drops before they impact users or services.
Threats Detection Identify anomalous behaviours like lateral movements, data exfiltration or policy violations. Integrate with IDS/IPS systems and export enriched flow data for advanced correlation.
Activities Logging Log and correlate user, device, and application activity across the network. Track who did what, when, and where, essential for compliance, auditing, and forensic investigations.
Unlimited Scalability Deploy network probes at branch offices or WAN edges to monitor local traffic, export flows, and detect issues closer to the source. Scale horizontally and monitor distributed networks at 100 Gbit and more.
Industrial Monitoring Bridge IT and OT/SCADA visibility, monitor industrial control systems, networked sensors, and traditional IT infrastructure in a unified view.
DDoS Mitigation Deploy on-premise mitigation to block volumetric attacks at the edge ensuring service continuity without relying solely on upstream providers.
Enterprise and Community Support Build your monitoring infrastructure with with the help of professional consultancy services, or leverage insights from a large community of industry professionals.
