# B A C Tech Intelligence
> Official Website Technology Detection, Infrastructure Profiling & Security Inspection Platform by B A C Web Development Services.

B A C Tech Intelligence (accessible at https://techstack.officialbac.in) inspects publicly observable signals of modern websites. It fingerprints client-side libraries, CMS engines, analytics, font scripts, CDNs, server-side frameworks, security headers, and DNS records without intrusive penetration testing.

## Core Capabilities
- **Technology Stack Fingerprinting**: Discovers over 80+ technology signatures across CMS, frameworks, programming languages, fonts, CDNs, web servers, and runtime environments.
- **Detailed Categorization**: Groups detected technologies into clear, functional categories (Analytics, Security & Bot Protection, Font Scripts, Web Frameworks, Web Servers, Programming Languages, CDN & Edge, Miscellaneous).
- **Version Group Extraction**: Discovers granular versions (e.g., Font Awesome 6.4.0, Google Analytics GA4, WordPress core, Next.js).
- **Security Headers Evaluation**: Audits HTTP response headers against OWASP guidelines (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy).
- **DNS & Edge Infrastructure Analysis**: Resolves public DNS records (A, AAAA, MX, TXT, NS, CNAME) and identifies edge reverse-proxies.
- **India DPDP Act 2023 Compliance**: Zero cross-site tracking, deterministic salted IP hashing for rate-limiting, and privacy-first statutory controls.
