D4 Secure Mobile – Architecture


Architecture Components

  • Segregated full disk encryption – leveraging hardware protected AES algorithms.
  • Non-Bypassable VPN Configuration – forcing all voice and data traffic through a VPN – eliminating the need for a MDM, allowing for full audit capability, and enabling internet access control.
  • Nested VPNs – enabling two, separate and distinct VPN clients on the device for double encryption – the ‘Gold Standard’ of data in transit protection.
  • Isolated Key Store – isolating the Key Store so that it is never accessible to the Android OS.
  • Secure Entropy Engine – isolating the random key number generator so that it is protected from Android OS attacks.
  • Government Certification – Designed for use beyond CSfC – but still commercial.
