Infrastructure Discovery

Map your organization's external infrastructure and attack surface. Discover subdomains, identify exposed services, and find potential security gaps before attackers do.

What's included

Subdomain enum Discover all subdomains

IP mapping Infrastructure topology

Security scan Exposed services detection

Asset inventory Complete digital footprint

SubdomainsSSL certsDNS lookupIP lookupTech stack

Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

Automate the workflow that works

Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide

Each page is shaped around a practical operational question, not just a raw lookup.

Signal

See the current DNS, registration, security, pricing, or reputation evidence.

Context

Compare the result with related checks so the next move is easier to trust.

Action

Copy examples, open linked tools, or move into API documentation when you need scale.

Trust signals before you integrate

Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.

Live Service status

Check live service health and documented failure responses before you integrate.

OpenAPI API artifacts

OpenAPI, Swagger, Postman, CLI, SDK, and MCP links are one click away.

API keys Protected access

Authenticated endpoints use API keys with clear credit costs before you call them.

10,000 Free allowance

Start with 10,000 monthly credits and upgrade only when usage grows.

Frequently asked questions

How are subdomains discovered?

We use Certificate Transparency logs, DNS enumeration, and passive reconnaissance to discover subdomains without active scanning.

Is this an active scan?

No. This is passive reconnaissance only. We don't probe or test your systems directly. We only gather publicly available information.

How can I reduce my attack surface?

The report flags unnecessary exposed services, outdated SSL certificates, and misconfigured DNS that you can fix.
