Passive fingerprinting from DNS, headers, JS, and SSL
Identify a company's technology stack without visiting their website. DNS records reveal hosting and email providers. HTTP headers expose web servers and frameworks. JavaScript libraries indicate frontend tools. SSL certificates show CDN and security infrastructure. All passive -- zero detection risk.
The Technographic Data Gap
Passive Multi-Signal Detection
Five independent signal sources cross-validate technology presence. Integrated into the enrichment pipeline -- not a separate tool.
DNS Analysis
MX records reveal email provider (Google Workspace, Microsoft 365). NS records reveal DNS provider. A/CNAME records reveal hosting and CDN.
HTTP Headers
Server headers reveal web server (nginx, Apache, IIS). X-Powered-By reveals frameworks (PHP, ASP.NET). Security headers indicate maturity.
JavaScript Detection
Script tags and resource URLs identify frontend frameworks (React, Vue, Angular), analytics (Google Analytics, Segment), and marketing tools.
Meta Tag Analysis
Generator meta tags reveal CMS (WordPress, Shopify, Webflow). OG tags reveal marketing tool integrations.
SSL Certificate
Certificate issuer indicates CDN (Cloudflare, AWS CloudFront). Organization field confirms company identity.
Cross-Validation
Multiple signal sources confirming the same technology increase confidence. Single-signal detections are flagged as tentative.
Detection Pipeline
Each stage processes data sequentially with full checkpoint/resume capability.
DNS Resolution
Query MX, NS, A, CNAME records. Map to known provider fingerprints.
SSL Inspection
Fetch certificate chain. Identify issuer, CDN, and organization.
HTTP Probe
Single HEAD request for server headers. Parse Server, X-Powered-By, X-Generator headers.
Resource Analysis
If crawling is enabled: analyze script tags, link tags, and resource URLs for technology fingerprints.
Meta Tag Parsing
Extract generator, og:*, and application-specific meta tags.
Fingerprint Matching
Match detected signals against technology fingerprint database.
Cross-Validation
Score confidence based on multi-signal confirmation. Flag single-signal detections.
Technical Workflow
# Tech detection runs as part of intelligence modules # Module: tech_detect in tools/base/module_registry.py # Integrated into enrichment pipeline python tools/autonomous_research.py --domain example.com # Intelligence modules run automatically: # 1. dns_intel -> hosting, email, DNS provider # 2. tech_detect -> CMS, frameworks, analytics, CDN # 3. ssl_intel -> CDN, certificate authority # 4. whois_intel -> registrar, hosting provider # Results stored in: database/intelligence.db
