How we protect your data
Core Architecture
Engineered for absolute perimeter defense
Zero-Trust Network Isolation
Our core systems operate in private, invisible networks. By completely disconnecting our databases and processing nodes from the public internet, we eliminate direct outside attacks before they can even start.
Enterprise-Grade Encryption
Your data is mathematically secured both in transit and at rest using bank-level 256-bit AES encryption. We enforce strict modern protocols (TLS 1.2+) to ensure your emails cannot be intercepted.
Hardware-Backed Secrets
Passwords and digital keys are never stored in our code. Instead, we use highly restricted, hardware-backed digital vaults. This ensures the keys to your data remain permanently locked away from prying eyes.
Immutable Archiving (WORM)
For regulated industries, we use WORM (Write Once, Read Many) storage technology. This guarantees that once an email is archived, it cannot be tampered with, altered, or deleted—satisfying strict legal requirements.
Continuous Resilience
Email is critical infrastructure. Our systems constantly monitor their own health, using smart load balancers and automated failover to ensure your mail keeps flowing smoothly, even during unexpected internet outages.
Auditable Infrastructure
Our entire global network is built using 'Infrastructure as Code'. This means our security rules are written, version-controlled, and tested like software, eliminating human error and making our defenses perfectly auditable.
Privacy & Compliance
Built to satisfy strict regulatory frameworks
From the Kenya Data Protection Act (2019) to global privacy standards, our infrastructure is designed to protect your data with absolute integrity and transparency. We manage our environments to ensure full regulatory compliance as a trusted data processor.
Strict Data Governance
We act as a responsible data processor. Our internal workflows ensure strict adherence to privacy laws, including the prompt and secure handling of Data Subject Requests (DSR) regarding your account information.
Automated Data Minimization
Our architecture is built to retain only what is strictly necessary. Temporary audit logs and forensic legal exports are automatically purged from our staging environments after 7 days.
PCI-DSS Level 1 Billing
Your billing information is completely isolated. All payments are processed by an audited, PCI-DSS Level 1 certified provider, meaning we never store or see your raw credit card data.
Cryptographically Verified Email History to Support Disputes and Litigation
In the event of litigation, initiating a Legal Hold ensures that critical emails bypass our automated retention purges, preserving them securely. When you generate a forensic archive export, our system bundles these immutable email objects with a secure JSON chain-of-custody manifest.
Mathematical signatures act as a tamper-evident seal. This provides undeniable proof to auditors or legal counsel that your records remain exactly as they were when they first arrived.
