About Subdomain Enumeration

Subdomain enumeration is a key OSINT technique for discovering additional attack surfaces and hidden services on a target domain. It helps identify development, staging, and forgotten subdomains that may be vulnerable.

OSINT & Security

Subdomains can reveal:

  • Internal services: dev, staging, test environments
  • Forgotten assets: old or unmaintained subdomains
  • Third-party integrations: SaaS, APIs, and more

Note: Only enumerate subdomains for domains you own or have permission to test.
