ESD is a Python-based subdomain enumeration tool that brute-forces and collects subdomains for a given domain. It uses AsyncIO/aioDNS for fast concurrent DNS queries and RSC (response similarity comparison) to handle wildcard DNS domains.
Use cases
- enumerate subdomains of a domain
- brute-force subdomains with a large dictionary
- discover subdomains behind wildcard DNS
- collect subdomains from certificate transparency and DNS transfers
- run asset discovery during a security assessment
When to choose
- you need fast async DNS-based subdomain brute-forcing in Python
- target domains use wildcard DNS resolution
- you want multiple collection channels (CT logs, DNSPod, page content, zone transfer) in one tool
When to avoid
- you need a maintained tool with active development (last release 2021)
- you need passive-only enumeration without DNS brute-forcing
- you need a GUI or web interface
