What you get

  • Website check — security headers, exposed files, TLS certificate, outdated software
  • Email spoofing — whether someone can send email as your domain (SPF, DKIM, DMARC)
  • Hidden doors — subdomains an attacker can find, and any open to takeover
  • Look-alike domains — registered names that could be used to impersonate you
  • Fix list — every finding ranked, with plain-English steps to lock it
