Use cases

What security teams build with Primitive Host

The real workflows security teams run on Primitive Host.

Phishing & brand abuse detection

Monitor new registrations that resemble your brands and escalate suspicious domains within minutes.

Learn more

Infrastructure mapping & attack surface

Enumerate domains pointing at your IP ranges and track assets that expand your external attack surface.

Learn more

Data enrichment & security research

Enrich events and alerts with trusted domain context to cut through noise and accelerate investigations.

Who it's for

One product, focused vertical: cybersecurity

Purpose-built for security. Secondary value for data teams and domain researchers.

Primary ICP

  • Threat intelligence teams building phishing, fraud, and abuse detections.
  • SOC & incident response teams enriching alerts and hunting campaigns.
  • Security product & data engineers powering commercial tools and pipelines.

If you work with zone files and feeds already, this fits.

The Primitive Advantage

  • Threat-Centric: Built for security workflows, not generic data science.
  • Production-Ready: Cleaned and normalized for SIEM/SOAR ingestion.
  • Built for Scale: Speed and volume required by modern SOC teams.

Problems we solve

Most domain datasets weren't built for detection

Legacy domain data sources miss new registrations or take days to update.

Without Primitive Host

  • Manual zone file ingestion drains engineering time.
  • Whois is rate-limited and inconsistent across TLDs.
  • Scraping is brittle and impossible to scale.
  • Domain context is trapped in spreadsheets and ad-hoc scripts.

With Primitive Host

  • New domains flow into your systems automatically via one API.
  • All teams share a single, consistent domain dataset.
  • Analysts focus on detections, not pipeline maintenance.
  • Ship new detections and reports faster.

Why Primitive

More than Whois, ICANN dumps, or scraping

Clean, structured, detection-ready — vs raw dumps and Whois.

Typical approaches

  • Raw ICANN dumps requiring custom parsing per TLD.
  • Whois lookups — slow, rate-limited, legally messy.
  • Scraping pipelines that break when policies change.

Primitive Host

  • Unified, cleaned dataset with consistent structure across all zones.
  • Fast REST API and bulk export for security research and production workloads.
  • Explicit focus on detection, enrichment, and monitoring.
