PurgeProof - Professional Data Sanitization Tool

Version 1.0.0 | NIST SP 800-88 Rev.1 Compliant | Cross-Platform

🎯 Overview

PurgeProof is an enterprise-grade, cross-platform data sanitization tool that securely erases data from storage devices in compliance with NIST SP 800-88 Rev.1 guidelines. Designed for cybersecurity professionals, IT administrators, and compliance officers who need reliable, auditable data destruction.

🏆 Key Highlights

  • ✅ Complete NIST SP 800-88 Rev.1 Implementation - All sanitization categories (Clear/Purge/Destroy)
  • ✅ Production Ready - Hybrid Rust+Python architecture
  • ✅ Cross-Platform - Windows, Linux, macOS support
  • ✅ Multiple Interfaces - CLI, Simple GUI (tkinter), Modern GUI (PyQt6)
  • ✅ Enterprise Security - Digital signatures, tamper-proof certificates, audit trails
  • ✅ Smart Command - Auto-detects available frameworks and dependencies
