Secure Mobile Handsets & Hardened Communications
Mobile privacy engineered for those who can’t afford compromise.
Most phones are built for convenience — not for security. For clients working in hostile environments, under surveillance risk, or requiring uncompromising mobile privacy, CDEC delivers fully hardened Android-based devices tailored to each operational profile.
We disable unnecessary services, tighten hardware-level protections, and apply bespoke hardening policies to eliminate hidden data flows. Each handset is configured by our specialists, ensuring total control and confidence in your digital footprint.
Whether you need a daily driver with maximum privacy or a burner phone that leaves no trace, we make mobile security simple, effective, and scalable.
Our hardened communications integrate seamlessly with Private Off-Grid Communications, Cyber Security Advisory and High-Risk Client Protection programmes, creating a secure ecosystem for people operating in high-risk or high-value environments.
What Makes Us Different
Custom Android OS+ Custom Hardening
All devices start with a bespoke Android OS, further enhanced with hardened network rules, stripped system services, secure DNS and sandboxed apps. Every handset undergoes forensic validation before delivery.Operational Guidance
We don’t just hand you a secure phone — we teach you how to use it securely. Our tradecraft-based sessions show how to maintain low-profile communications, avoid metadata leaks, and operate discreetly across borders or hostile areas.ATAK Integration
For operational users, we provide pre-configured handsets with ATAK (Civ or Mil) integration — offline mapping, mesh connectivity, and plugin support for mission coordination when paired with Private Off-Grid Communications systems.Burner Setup & Hygiene
We offer structured walk-throughs for creating clean burner builds — removing bloatware, disabling telemetry, and ensuring anonymous SIM and Wi-Fi usage. Each build is verified against forensic signatures for privacy assurance.
For executive protection deployments, hardened devices are often issued alongside TSCM Bug Sweeps and Physical, Electronic & Aerial Surveillance to validate the surrounding communication environment before use.
