Uncover vulnerabilities
before they strike
Mergen continuously monitors your external attack surface, discovering assets and exposing risks in real-time.
Reconnaissance capabilities
Eight specialized engines working continuously to map your attack surface from an adversary's perspective.
Subdomain Discovery
Passive enumeration via certificate transparency, DNS brute-force, and permutation scanning across thousands of resolvers.
Certificate Transparency logs, DNS brute-force, permutation scanning, zone transfers, and passive DNS replication. Discovers subdomains even when they resolve to internal networks or behind CDNs.
Port Analysis
Masscan for rapid discovery, Nmap for deep service fingerprinting and version detection.
Full TCP/UDP sweep via Masscan at 10M+ packets per second, followed by targeted Nmap scans for service fingerprinting, version detection, OS identification, and script-based vulnerability enumeration.
Web Crawling
JavaScript-aware crawling with API endpoint extraction and form discovery.
Chromium-based crawler renders JavaScript, extracts API routes from compiled bundles, discovers hidden forms, maps authentication endpoints, and catalogs every reachable resource.
Technology Detection
Identify 7,500+ technologies from response signatures — frameworks, CMS, analytics, CDNs, and version numbers.
IP Intelligence
GeoIP mapping, CDN detection, ASN correlation, and reverse DNS across every discovered host.
Historical Data
URL discovery from Wayback Machine, Common Crawl, and passive DNS archives spanning years of data.
Continuous monitoring pipeline
Set your scope once. Mergen handles the rest.
Define Scope
Specify domains, IP ranges, and seed targets. Mergen respects your boundaries.
Discover
Automated reconnaissance runs continuously across all eight engines, mapping your external footprint from an adversary's perspective.
Monitor
Real-time alerts when new assets appear, configurations change, or vulnerabilities are exposed. No false-positive fatigue.
What Mergen finds
Real findings from real scans. Every asset, service, exposure, and endpoint your organization has connected to the internet.

Built for security operations
Different roles, same surface. From the SOC to the CISO, everyone sees what matters to them.
SOC Analyst
New findings triaged by severity, validated against accurate scope, and escalated through webhook-integrated workflows.
Minute-to-value: 30s
Security Engineer
Shadow IT and forgotten services flagged on discovery. Asset history tracked through point-in-time comparisons.
Average surface growth: 8-12%/mo
CISO
Organizational exposure at a glance, with executive-ready summaries and trend charts for board reporting.
