How it works
From a bare domain to a signed report — one continuous pipeline.
Point it at a domain. It discovers the footprint, attributes the infrastructure, triages every finding against real-world exploit data, and writes the deliverable. No questionnaires. No blind spots.
→
01
Discover
DNS, subdomains, hosts, ports, cloud providers, email posture, leaked credentials — the map draws itself.
→
02
Attribute
Owned vs. shared infrastructure, CDN and WAF context, tech fingerprints — signal separated from edge noise.
→
03
Triage
CVSS + EPSS exploit probability + evidence. False-positives flagged once, suppressed forever.
→
04
Report
Executive verdict, findings, remediation roadmap — in the house style of top diligence firms. Deck + PDF.
01 / Reconnaissance

The full external footprint, automatically.

Every host, port, certificate, and cloud attribution — discovered and kept fresh as the surface shifts. What an attacker would spend weeks assembling, in minutes.

  • DNS & subdomain enumeration
  • Open port & service fingerprinting
  • Cloud & CDN infrastructure attribution
  • OSINT: SPF / DMARC / DKIM, GitHub leaks, job signals

02 / Triage

Signal, not noise.

Every finding is weighed against exploit probability and real-world evidence — not scanner defaults. The verdict you get is the one you can defend in a boardroom.

  • EPSS-weighted severity, not raw CVSS
  • False-positive memory across scans
  • AI-assisted root-cause & blast-radius
  • Contextual RAG verdict per category

Whoever needs the truth about an attack surface.
Security teams
Continuous surface monitoring
Track exposure drift between scans. Get alerted when new ports open, CVEs match your stack, or email posture degrades — all on your own infrastructure.
VC & M&A advisors
Technical due diligence in hours
A complete TDD pack with verdicts and remediation roadmaps, generated from live scan data — not questionnaires. Attach it straight to the IC memo.

See what a buyer will find
A real-time mirror of your external attack surface. Know what's exposed and misconfigured before an acquirer's security team does.

The gap between what a company thinks is exposed and what an attacker can actually reach is where acquisitions fall apart.
