Company Domain Tech, DNS & Security Audit

Audit company domains for public website metadata, tech stack, DNS, TLS, RDAP, robots.txt, and sitemap signals. Enter company domains or URLs and get a source-linked domain audit row for vendor research, market mapping, and portfolio hygiene. No login, no paid API key, no private pages, and no person-targeting output.

Store Quickstart

Run one audited domain:

{
  "domains": ["stripe.com"],
  "auditLevel": "techstack_report",
  "dryRun": false
}

Run a lighter DNS/TLS check:

{
  "domains": ["notion.so", "shopify.com"],
  "auditLevel": "security_audit",
  "dryRun": false
}

Preview the output shape without live requests or billing:

{
  "dryRun": true
}

What You Get

• Website reachability, final URL, page title, and meta description.
• Tech stack hints from public HTML and response headers.
• DNS posture: A, MX, NS, SPF, DMARC, and derived mail provider.
• RDAP registration age, registrar, expiry, and status flags.
• TLS certificate issuer, validity window, days to expiry, and SAN domains.
• robots.txt / sitemap presence and approximate sitemap URL count.
• A completeness score and signalsResolved count for filtering weak records.

Input Fields

Field	Description
domains	Company domains or URLs. URLs are reduced to hostnames; www. and duplicates are removed.
auditLevel	basic, security_audit, or techstack_report. This selects the value event used for billing.
proxy	Optional. Public sources usually work without a proxy; use only for large compliant runs.
dryRun	When true, emits one illustrative sample row without live calls or billing.

Compliance Guardrails

• Uses public, non-authenticated sources only: company website, DNS, RDAP, TLS, robots.txt, and sitemap.
• Blocks localhost, private network ranges, metadata hosts, non-HTTP(S) URLs, and redirects into private addresses.
• Stops on login walls, CAPTCHA, access-block pages, oversized responses, and repeated redirects.
• Does not access private dashboards, paid databases, account-only pages, or bypass controls.
• Output is not a legal, security, procurement, or vendor-certification opinion.
