Start Monitoring My Brand

Lookalike Domain Generator

Generate typo & homoglyph domains for your brand and see which are active (MX/A/NS). Great for phishing defense and monitoring.

Why this matters

  • Phishing loves lookalikes. Attackers register confusingly similar domains to steal credentials and money.

  • Email deliverability is a clue. If a lookalike has MX records, it can send/receive email — high risk for phishing.

  • Fast triage. We show which candidates are active so your team knows what to act on first.

How it works

  1. Generate candidates from your brand/domain using typos, transpositions, keyboard-adjacent keys, homoglyphs (IDNs), prefixes/suffixes (e.g., secure-, billing-), and TLD swaps.

  2. Check DNS to see if a candidate is alive: MX (email), A/AAAA (web), NS (delegation).

  3. Score & rank by risk, then give you a CSV and a “Protect my brand” CTA to our response team.

What we check

  • Typo & transposition variants: e.g., bftrsecurity.com, bfrtsecurtiy.com

  • Homoglyphs / IDN confusables: e.g., xn--bfrtsecur1ty-… (Cyrillic/Greek swaps)

  • Prefix/Suffix combos: login-bfrtsecurity.com, bfrtsecurity-support.com

  • TLD swaps: .com, .net, .org, .ai, .io, .in, .co.in, .xyz, etc.

  • DNS activity: MX, A/AAAA, NS (active domains are prioritized)

Frequently Asked Questions (FAQ) - Lookalike Domain Generator

  • A domain intentionally registered to resemble your brand (by typo, homoglyph, or TLD change) to trick users.
  • Registering common misspellings (e.g., micorsoft.com) so victims land on a fake page or get phished.
  • Using visually similar characters from other alphabets (like Cyrillic а vs Latin a) that render almost the same in browsers and email clients.
  • No. It only uses public DNS. We can add monitoring/alerts and defensive registrations as a managed service.
  • No single tool can. We focus on highest-probability variants and activity checks to surface the most actionable items fast.
  • Some providers block unauthenticated mail anyway. Your domain posture still needs improving to protect broadly, not just at Gmail.
  • Yes. We prepare evidence, contact registrars/hosts, and support UDRP/URS where applicable. See our Managed Website Security.
  • Yes—publish separate DMARC for subdomains or enforce parent sp= policy. We’ll advise the cleanest layout.
  • Often 2–4 weeks with proper monitoring and sender inventory. We can accelerate if your sender set is simple.
