What ntop can do for you
Bandwidth Monitoring Monitor network traffic in real time via flow data or traffic mirrors. Spot congestion and anomalies fast, with native NetFlow and sFlow support.
Observability Track network and application performance metrics to catch latency spikes, packet loss, and degradation before they hit users.
Threat Detection Spot lateral movement, data exfiltration, and policy violations. Integrates with IDS/IPS and exports enriched flow data for deeper correlation.
Activities Logging Log and correlate user, device, and application activity network-wide — who did what, when, and where — for compliance, auditing, and forensics.
Unlimited Scalability Deploy probes at branch offices and WAN edges to monitor traffic at the source. Scales horizontally to 100 Gbit+ across distributed networks.
Industrial Monitoring Unify IT and OT/SCADA visibility, monitoring industrial control systems and networked sensors alongside standard IT infrastructure.
DDoS Mitigation Block volumetric attacks on-premise, at the edge, for service continuity without relying solely on upstream providers.
Enterprise and Community Support Get professional consultancy or tap into a large community of network monitoring experts.
