Enterprise Security Architecture

Security Assurance

Built with zero-trust principles: client-side browser isolation, 256-bit encryption in transit, and automated ephemeral file lifecycles.

1 Client-Side Browser Execution Sandbox

The cornerstone of security at The PDF Lab (www.thepdflab.com) is client-side execution:

256-Bit Local Execution Security Everyday PDF operations (merge, split, reorder, compress, rotate, protect, redact, sign) run completely inside your browser's WebAssembly and JavaScript sandbox. Your document bytes never touch an external network interface during these local operations.

2 Transport Security & SSL/TLS Encryption

All traffic between your browser and our servers is protected using high-grade SSL/TLS 1.3 encryption with 256-bit key exchanges. HTTP Strict Transport Security (HSTS) is enforced to ensure no unencrypted plain-text communication occurs.

3 Ephemeral AI Storage & Automated Cleanup

For AI tools requiring server-assisted processing (e.g., AI Summarizer, Chat with PDF, Translate PDF, PDF to MP3):

  • Files are processed in isolated, non-public directory paths with restricted OS-level permissions.
  • Automated cron jobs purge temporary files immediately after conversion cycles.
  • No document content is ever indexed, shared, or used to train public machine learning models.

4 Authentication & Credentials Protection

User passwords are never stored in plain text. We utilize industry-standard Bcrypt hashing with random salt generation. Sensitive API keys and credentials are kept strictly out of web-accessible directories and source control.

5 Vulnerability Reporting & Security Contact

We welcome reports from security researchers and users. If you discover a potential vulnerability, please email our security team directly at naushad@thepdflab.com or visit www.thepdflab.com.
