appreciative_lobster-owner/dnstwist-domain-typosquat-audit

Audit bounded lookalike-domain mutations with DNS-only A, AAAA, MX, NS, and UNKNOWN evidence.

Compare Google Maps exports by placeId and preserve a scoped observation history.

Audit any domain's email and web security in seconds: SPF, DMARC, DKIM, DNSSEC, MTA-STS, BIMI, CAA, SSL certificate expiry and HTTP security headers. A-F grade plus prioritized fixes. Bulk lists or one domain at a time for AI agents.

Brand protection in one call: generate lookalike domains for a brand (typos, transpositions, homoglyphs, hyphenation, TLD swaps) and check via DNS which are actually registered. The registered lookalikes are your threat list for phishing and brand abuse. Charged only on completed audits.

Bulk domain lookup: registrar, creation and expiry dates (RDAP/WHOIS), DNS records, email provider with SPF/DMARC, SSL certificate expiry, and website status with redirects. Paste domains, URLs or emails.

Clean a bulk email list without sending anything. One row per address: MX records and mailbox provider, SPF and DMARC policy, disposable-domain and role-address flags, typo correction, and a 0-100 deliverability score. No SMTP probe, no sender reputation risk.
