## What it is
Kunai is an eBPF-based threat-hunting and security-monitoring tool for Linux, often described as the Linux counterpart to Sysmon on Windows. It captures kernel-level events with eBPF probes and delivers chronologically ordered, enriched, and correlated events in a self-contained Rust binary that is also container-aware.

## Use cases
- monitor Linux system events for security threats
- hunt for malicious activity on Linux hosts
- get a Sysmon-like event stream on Linux
- trace container activity with eBPF
- correlate and enrich kernel events for incident response
- detect suspicious process and file activity in real time

## When to choose
- you need kernel-level event monitoring on Linux with a single standalone binary
- you want container-aware security telemetry
- you need chronologically ordered, correlated events for threat hunting
- you prefer a Rust/eBPF (Aya-based) tool over kernel modules

## When to avoid
- you need security monitoring on Windows or macOS
- your kernel is too old or incompatible with eBPF probes
- you need a full SIEM or alerting pipeline rather than an event source
- you cannot run the tool with elevated (root) privileges
