Manotron
Hardware-anchored smartphone protection for high-stakes operations
A hardware-anchored cyber retransmission case that transforms any smartphone into a certified secure communication endpoint. Dual-layer encryption, baseband isolation, and NIST-aligned PQC for government, defense, and enterprise field operations.
Your smartphone is the weakest link
Modern smartphones leak data through baseband processors, unencrypted app traffic, and supply-chain vulnerabilities. For government, defense, and enterprise teams operating in high-risk environments, a compromised phone means compromised operations. Manotron isolates the phone from network threats with a hardware-anchored retransmission case — no app-layer security can match physical baseband isolation.
- Baseband processors expose phones to direct radio-level attacks — no app-layer security can prevent this
- Standard VPNs encrypt app traffic but leave the device's radio interface and OS vulnerable to lateral access
- Supply-chain compromise in commodity smartphones creates persistent, undetectable backdoors
- Field operatives need certified retransmission — not consumer-grade mobile security
What it does
Cyber Retransmission Case
A modular hardware case that transforms Samsung S23/S24/S25 series devices into certified retransmission endpoints. USB-C tether only — enumerates as Ethernet (CDC-ECM), no mass-storage or ADB classes exposed.
Dual-Layer Encryption
Outer VPN tunnel automatically established to an authorized grey-network gateway. Inner end-to-end session encryption for calls, messages, and data. No traffic passes outside these tunnels — all communication is protected before leaving the device.
Baseband Isolation
Physical separation between the phone's USB data interface and the embedded LTE modem. Bridge controller and routing firewall eliminate any shared path between user data and radio interfaces, preventing lateral access or cross-domain leaks.
Minimal Attack Surface
Wi-Fi, Bluetooth, NFC, and local debug interfaces physically removed or disabled. Single-purpose retransmission bridge with locked U-Boot recovery, HTTPS-only management, and strict role-based access control.
Secure Firmware Lifecycle
Signed OpenWrt image with secure-boot validation. Vendor-vetted release pipeline. Controlled OTA deployment through authenticated VPN channel. Every firmware update cryptographically authenticated and logged for full traceability.
Global LTE / 5G Connectivity
Global LTE + sub-6 GHz 5G (bands n1, n3, n5, n7, n28, n77/n78/n79). mmWave ready. Supports North America, EMEA, and APAC frequency bands for mission-critical connectivity worldwide.
A clear path to quantum safety
Provision Case
Manotron case is provisioned with PQC certificates from QuantumKey PKI. Device identity bound to the hardware enclave. Firmware signed and verified at secure boot.
Attach Smartphone
Operative attaches the case to a supported Samsung device via USB-C. Case enumerates as Ethernet only — no mass-storage, no ADB, no debug access. Baseband physically isolated.
Establish Tunnels
Outer VPN tunnel auto-establishes to the authorized grey-network gateway using PQC key exchange. Inner session encryption activates for all calls, messages, and data via the QTRON app.
Operate Securely
All communication passes through dual-layer encryption. Baseband isolated. No traffic leaves the device unencrypted. Operative communicates with mission-grade security in any environment.
