sx: Fast, modern, easy-to-use network scanner

by do son · May 3, 2021

sx is the command-line network scanner designed to follow the UNIX philosophy.

The goal of this project is to create the fastest network scanner with clean and simple code.

⚡ 30x times faster than nmap
ARP scan: Scan your local networks to detect live devices
ICMP scan: Use advanced ICMP scanning techniques to detect live hosts and firewall rules
TCP SYN scan: Traditional half-open scan to find open TCP ports
TCP FIN / NULL / Xmas scans: Scan techniques to bypass some firewall rules
Custom TCP scans with any TCP flags: Send whatever exotic packets you want and get a result with all the TCP flags set in the reply packet
UDP scan: Scan UDP ports and get full ICMP replies to detect open ports or firewall rules
Application scans:
- SOCKS5 scan: Detect live SOCKS5 proxies by scanning ip range or list of ip/port pairs from a file
- Docker scan: Detect open Docker daemons listening on TCP ports and get information about the docker node
- Elasticsearch scan: Detect open Elasticsearch nodes and pull out cluster information with all index names
JSON output support: sx is designed specifically for convenient automatic processing of results
