additional context — IP + user-agent lookups

lookups that complement a dossier — useful when investigating a finding, but not part of the dossier engine itself.

IP lookup — geolocation, ASN, ISP for any IP address surfaced by the DNS or redirect sections.
user-agent parser — the browser/OS/device the request came from.
single-record DNS lookup — drill into one record type at a time.

A/AAAA records present

Why it matters: Without authoritative A or AAAA records on the apex, the domain is unreachable. Missing baseline DNS shows up in vendor reviews as evidence of unmanaged infrastructure (SOC 2 CC6.6).

mx

high

no MX records — domain cannot receive email

Why it matters: MX records direct inbound mail. Misconfiguration silently breaks email delivery and lets attackers stand up parallel MX hosts for spoofing campaigns (ISO 27001 A.8.21).

Recommendations

Add MX records pointing to your mail provider (e.g. MX 10 mail.example.com)
If the domain should not receive email, publish 'v=spf1 -all' to signal no senders

~all softfail — receivers may still accept

Why it matters: SPF tells receiving servers which hosts may send mail for the domain. Without it, any sender can forge the envelope-from — the primary mechanism behind business-email-compromise (SOC 2 CC6.7).

Recommendations

Move to -all (hardfail) once your mail flow is confirmed — softfail gives no real protection

dmarc

Open standalone →

no DMARC record — spoofing risk

Why it matters: DMARC binds SPF and DKIM into an enforceable policy (quarantine or reject) and surfaces spoofing attempts via aggregate reports. `p=none` or absent means spoofing succeeds silently (SOC 2 CC6.7).

Recommendations

Publish a DMARC TXT record at _dmarc.<domain>: v=DMARC1; p=none; rua=mailto:dmarc@<domain>
Start with p=none to collect reports, then move to p=quarantine and finally p=reject

no DMARC record

dkim

Open standalone →

no DKIM selectors found — likely not configured

Why it matters: DKIM signs outbound mail so receivers can detect tampering. Missing selectors or rotated-away keys break DMARC alignment and let receivers downgrade trust (ISO 27001 A.8.24).

Recommendations

Enable DKIM signing in your mail provider and publish the provided TXT record
Common selectors: google._domainkey, selector1._domainkey (Microsoft), mail._domainkey

no DKIM record on probed selectors (default, google, k1, selector1, selector2, mxvault)

tls

high

Open standalone →

cert expires in 7 day(s)

Why it matters: A valid current TLS certificate is the baseline for data in transit. Expiry, weak chain, or hostname mismatch break HTTPS and fail PCI 4.2.1 / SOC 2 CC6.1.

Recommendations

Renew the certificate now — most CAs allow renewal 30 days before expiry
Run: certbot renew --force-renewal

medium

redirects to different domain: threads.com

Why it matters: Bare HTTP requests must redirect to HTTPS without dropping the user mid-chain. Plain-text fallback or open redirects fail PCI 4.2.1 and feed phishing chains (SOC 2 CC6.6).

Recommendations

Verify this cross-domain redirect is intentional (e.g. domain migration or CDN)
Ensure the destination domain is owned and expected — unintended redirects can leak traffic

Why it matters: Security headers — HSTS, CSP, X-Frame-Options, Referrer-Policy — defend against XSS, clickjacking, and downgrade attacks. Absent headers map directly to OWASP ASVS V14 findings (ISO 27001 A.8.23).

Recommendations

Add response header — Referrer-Policy: strict-origin-when-cross-origin
