## What it is
ntopng is a web-based network traffic monitoring and cybersecurity application that provides real-time visibility into hosts, applications, and flows. It supports NetFlow, sFlow, IPFIX, SNMP, and eBPF, and offers bandwidth monitoring, observability, and threat detection from a single console.

## Use cases
- monitor network bandwidth in real time
- detect data exfiltration and lateral movement
- analyze NetFlow and sFlow data
- troubleshoot network latency and packet loss
- monitor hosts and applications on my network
- export enriched flow data to a SIEM
- track user and device activity network-wide

## When to choose
- you need a self-hosted web UI for real-time traffic analysis
- you want flow-based monitoring with NetFlow/sFlow/IPFIX support
- you need threat detection and behavioral checks alongside traffic monitoring
- you run firewalls like pfSense/OPNsense and want integrated traffic visibility

## When to avoid
- you only need simple uptime or service health checks rather than traffic analysis
- you need full packet capture and long-term storage without additional ntop products
- you require a lightweight agentless solution on hosts rather than network-level monitoring

## Facets
- artifact type: application
- maturity: stable
- function: monitoring, analytics, security, search-engine, data-visualization
