ntopng grew from traffic monitor into asset inventory and vulnerability scanner — one major at a time

network-monitoringasset-inventoryclickhousevulnerability-scanningobservability
◆Current state
ntopng ships roughly one stable major a year. The 6.x line added vulnerability scanning and CVE support, then an Asset Inventory and Digital Twin with an assets dashboard, then autonomous-system dashboards with native ClickHouse Cloud SSL and a direct flow dump mode for real-time export. The last published release was 6.6 in November 2025, so this feed is currently quiet.
◆Where it's heading
Each major has annexed an adjacent category rather than deepening flow analysis: security posture in 6.0, asset management in 6.4, and infrastructure-scale visibility in 6.6. Underneath, ClickHouse has steadily replaced the older storage paths, moving from an option in 5.2 to the assumed backend with a real-time export mode. The result is a product competing well outside its original network-monitoring lane.
◆Prediction
With the last release nine months old, the next major is overdue; based on the pattern it would extend the asset and security surfaces rather than the flow engine.
