# LARK: Lightweight AI Reconnaissance Kit Documentation

> Official documentation for the LARK cybersecurity appliance — network traffic analysis, threat detection, and edge AI in one portable unit.

The Lightweight AI Reconnaissance Kit (LARK) is a self-contained cybersecurity platform that gives your team full visibility into network activity from the moment it is powered on. It captures network traffic passively, detects threats, retains full packet data, and supports AI-assisted analysis — all running locally on the appliance, with no cloud connectivity required.

## What the LARK does

The LARK observes network traffic passively using a TAP or switch SPAN port, then turns that traffic into structured telemetry, alerts, and retained packet data — all accessible through a browser on any connected laptop.

## LARK models

The LARK is available in three models — SWIFT, PEREGRINE, and APEX — all running the same software. They differ in compute, storage, and the number of nodes.

<Tip>
  If you are setting up a LARK for the first time, start with the [Kit Composition](/kit-composition/kit-overview) and [Setup](/setup/setup-overview) sections. If the appliance is already running, jump to [Administration](/administration/administration-model) or [Data Management](/data-management/data-overview).
