What SquatWatch detects

Typosquatting & Phishing

Detects registered lookalike domains that attackers use to harvest credentials, intercept email, or redirect users — classic vectors for BEC and supply-chain attacks.

Brand & Trademark Infringement

Finds domains that impersonate your brand across TLDs and common misspellings — useful for legal teams building takedown cases or proactive brand monitoring.

Azure Tenant Hijacking

Checks whether a lookalike domain has an active Microsoft 365 / Azure AD tenant — a strong indicator of a targeted attack or corporate espionage attempt via email spoofing.

URL Hijacking & SEO Squatting

Uncovers domains parking on your brand's traffic, scraping your content, or ranking in search via lookalike URLs — costing you visits, revenue, and reputation.

MX-Based Threat Detection

Lookalike domains with live MX records are high-risk — they can receive misdirected email containing sensitive business data. Fingerprints the mail provider for further investigation.

SSL / Certificate Monitoring

Queries Certificate Transparency logs via crt.sh to find TLS certificates issued for lookalike domains — often the first sign a phishing site is being stood up.
