Security Architecture Questions

Understanding our advanced protection mechanisms

How is RenMail quantum-resistant?

RenMail implements lattice-based cryptographic algorithms (CRYSTALS-Kyber and CRYSTALS-Dilithium) that are recognized by NIST as post-quantum standards. Unlike traditional RSA/ECC encryption that quantum computers can break, our algorithms rely on mathematical problems that remain hard even for quantum systems. We also use hybrid encryption that combines classical and post-quantum cryptography for maximum security.

What makes Swiss data bunkers more secure?

Our Swiss data centers are located in former military bunkers deep within mountains, protected by multiple physical security layers including biometric access, 24/7 armed guards, and electromagnetic pulse shielding. Switzerland's strict privacy laws prevent foreign governments from accessing data without due process, and the geographic location provides protection against natural disasters and political instability.

How does temporal encryption work?

Temporal encryption allows you to set precise expiration times for emails - from 5 minutes to 30 days. Once the time elapses or after the recipient reads the message (your choice), the encrypted data is permanently destroyed using cryptographic shredding techniques. Even we cannot recover deleted messages. This is perfect for sensitive negotiations, whistleblower communications, or any content that shouldn't persist.

Can I use RenMail for regulatory compliance?

Absolutely. RenMail helps organizations comply with GDPR, HIPAA, SOX, and other regulations through features like automatic data retention policies, audit trails, and blockchain-verified delivery receipts. Our Swiss jurisdiction provides additional legal protection, and we offer compliance documentation packages for enterprise customers.

How does stealth mode protect my privacy?

Stealth mode eliminates all metadata that could reveal your communication patterns. It disables read receipts, typing indicators, and online status. Messages are routed through our proprietary anonymity network that separates your identity from your communications. Even under network analysis, it's virtually impossible to determine who you're communicating with or when.
