## What it is
Ettercap is a comprehensive open-source suite for man-in-the-middle attacks on local networks. It supports live connection sniffing, on-the-fly content filtering, and active/passive dissection of many protocols, with CLI, ncurses, and GTK interfaces.

## Use cases
- sniff network traffic between two hosts
- perform ARP poisoning / man-in-the-middle attacks
- intercept and modify HTTP traffic with SSLStrip
- filter and inject content into live connections
- passively dissect protocols and analyze hosts on a LAN
- capture credentials on a switched network during a pentest

## When to choose
- you need a mature MITM tool for network penetration testing
- you want protocol dissection and content filtering in one suite
- you're working on Linux/BSD/macOS with libpcap available
- you need plugin extensibility for custom attack modules

## When to avoid
- you need a modern GUI-focused traffic analyzer like Wireshark for passive inspection
- you're on an unsupported platform like Solaris or newer Windows without extra setup
- you want encrypted-traffic interception without dealing with certificate warnings
- you need a pure passive sniffer without MITM capabilities
