Security-First Architecture

Built for trust at every layer

MyGuardian's architecture is designed from the ground up for security, privacy, and reliability. Military-grade encryption, zero-knowledge architecture, and multi-region redundancy ensure your most critical moments are protected by technology you can trust.

Your data, your keys

End-to-end encryption means even we can't access your recordings. Your private vault is encrypted with keys only you control.

🔐

AES-256 at Rest

All stored data is encrypted using AES-256, the same standard used by governments and military organizations worldwide. Keys are rotated automatically using least-privilege principles.

Algorithm
AES-256-GCM
Key Rotation
90 days automatic
Key Storage

TLS 1.3 in Transit

Every connection uses TLS 1.3 with perfect forward secrecy. Even if a key is compromised, past communications remain secure.

Protocol
TLS 1.3
Cipher
ECDHE + AES-GCM
Certificate
EV SSL, HSTS

Zero-Knowledge Vault

Your private locker is end-to-end encrypted with keys derived from your passphrase. We mathematically cannot access your data—only you hold the key.

Tamper-Evident Logs

Cryptographic hashes and append-only logs create an immutable audit trail. Any modification is immediately detectable and provable in court.

Global, redundant, always-on

Multi-region storage with automatic failover ensures your recordings survive any disaster. Offline-first architecture means protection works even without connectivity.

Multi-Region Replication

Every recording is replicated across three geographic regions automatically. If an entire data center goes offline, your data remains accessible.
