ASM Domain & Subdomain Data

ASM Domain & Subdomain Data

Structured, historical attack surface intelligence for cybersecurity

Get Early Access

Strategic ASM partner for cybersecurity companies that:

Operate continuous external asset discovery

Serve large enterprises with complex, global infrastructures

Rely on domain and subdomain data as a core input

If your product accuracy depends on knowing what exists, what existed before, and what just appeared, this data is built for you.

Cybersecurity teams fail quietly when input data is incomplete.

Common issues we see across the market:

  • Missing subdomains, especially deep or rarely used one
  • Poor coverage outside major TLDs and regions
  • No reliable historical baseline for validation
  • High noise from unstructured or scraped sources
  • Blind trust in self-scanning without independent verification

For enterprise customers, these gaps translate directly into unmanaged exposure.

What makes DomainCrawler different

DomainCrawler is not a scanner and not just another tool.

We are an Infrastructure-level ASM provider focused on one thing:

Foundational domain and subdomain visibility enriched with exposure context.

Our differentiation is structural, not cosmetic.

1. Subdomain coverage as a primary focus

  • Systematic discovery of subdomains across the global namespace
  • Strong coverage of long-tail, regional, and low-traffic assets
  • Designed as an independent external data source for cyber security companies

2. History by default, not as an add-on

  • Domain and DNS data collected and retained since 2008
  • Historical subdomain presence, not just current state
  • Enables trend analysis and asset lifecycle tracking

3. Structured data, ready for platforms

  • Normalized datasets, not raw crawl output
  • Clear schemas suitable for automation and enrichment
  • Built for ingestion into production pipelines

4. Independent visibility

  • Data source independent from customer environments
  • Helps prevent false confidence caused by incomplete or biased discovery inputs
  • Adds an external visibility layer to identify blind spots and coverage gaps

What data Cybersecurity company gets get

DomainCrawler delivers domain intelligence with subdomain coverage, enriched with context Cybersecurity teams actually use.

Core coverage

  • Domains and subdomains (current and historical)
  • Newly observed and reactivated assets
  • DNS records: A, AAAA, CNAME, CAA, MX, TXT, NS

Infrastructure context

  • IP mappings (IPv4 and IPv6)
  • ASN and hosting attribution
  • Redirect chains and external dependencies

Lifecycle and state signals

  • First seen / last seen timestamps
  • DNS and hosting changes over time
  • Parked, redirected, inactive, and developed states

This allows Cybersecurity teams to distinguish between:

  • Active vs legacy assets
  • Stable infrastructure vs ephemeral exposure
  • Noise vs inventory that matters

How ASM providers use our data

DomainCrawler data is typically used as:

External discovery layer – provide authoritative asset inventories

Validation layer – verify customer-provided scopes

Historical reference – understand how attack surfaces evolved

Coverage benchmark – measure what scanners may miss

You retain ownership of scoring, prioritization, and remediation.
We provide the visibility that makes those steps reliable.

Built for enterprise exposure management and continuous security programs

Cybersecurity companies serving large organizations require:

  • Predictable data structures
  • Global coverage
  • Long-term continuity
  • Clear data provenance

DomainCrawler is designed as a foundational dataset, not a point feature.

We support:

High-volume API access

Integration into existing data pipelines

Long-term partnerships with security vendors

Why choose DomainCrawler

  • Coverage depth beyond common DNS and CT sources
  • Historical visibility that scanners cannot recreate
  • Independent data to reduce blind spots
  • A provider role that does not compete with your product

Visibility is the foundation of protection.

DomainCrawler supplies the domain and subdomain intelligence Cybersecurity companies depend on.
