Cerberus

High-performance eBPF network monitoring tool for real-time traffic visibility and device discovery

Webfree

Cerberus is a free, open-source network monitoring tool built with eBPF that gives real-time visibility into network traffic, automatic device discovery, and Layer 7 protocol inspection (DNS, HTTP, TLS) at the kernel level, shown through a web dashboard. It flags behavioral anomalies like SYN-heavy or high-volume traffic patterns consistent with scans or floods, though it is explicitly not a full intrusion detection system. It is aimed at network administrators and home lab operators who want kernel-level traffic visibility without deploying a heavier IDS stack.
