Posture summary

Public attack surface (971 hostnames in Certificate Transparency)

Hostnames this organization published in public TLS certificates. Passive OSINT — nothing was scanned; a wildcard certificate is in use, so the real footprint may be larger.

The hostname inventory — which forgotten hosts exist and where — is part of the complete audit for this domain.

Lookalike domains (38 registered of 67 checked)

Registered permutations of this domain. Existence is a fact, not an accusation — ownership and intent are not assessed. Those able to receive mail are the ones usable for invoice fraud and phishing.

35 further registered lookalike(s), 23 of them able to receive mail. The full list, with mail capability for each, is part of the complete audit.

Recommendations

• mediumEnable DNSSEC

  DNSSEC signing was not detected for this domain.

• criticalReset credentials seen in infostealer logs

  Public infostealer telemetry associates 50 employee credential set(s) with this domain — passwords captured from infected devices, which bypass password policy and often session-hijack past MFA. The most recent dates from 2026-08-03. Most commonly RedLine. Force a reset for the affected services, invalidate active sessions, and check the devices themselves.

• highMonitor lookalike domains

  23 registered lookalike domain(s) can receive mail, which is what makes them usable for invoice fraud and credential phishing. Monitor them and consider defensive registrations.

• mediumReview the public subdomain footprint

  971 hostnames for this domain appear in public Certificate Transparency logs. Retire forgotten hosts — stale subdomains are a common entry point and a takeover risk.
