Pre-Configured Blank Signal Account & Threema License - Instant, Private Messaging
Signal Account - Anonymous Communication
Each Fortress Phone includes an optional pre-configured blank Signal account, allowing users to begin secure, encrypted communication immediately - without having to link their personal phone number.
This account is set up anonymously and comes ready to use, ideal for those who need secure communications without connecting their identity or SIM. It provides full access to Signal's end-to-end encrypted messaging, voice, and video calls, offering immediate operational security out of the box.
Advanced Security Features:
- Signal Protocol Encryption: Industry-leading end-to-end encryption for all communications
- Perfect Forward Secrecy: New encryption keys generated for each message session
- Double Ratchet Algorithm: Continuous key rotation for maximum security

- Disappearing Messages: Automatic message deletion after specified timeframes
- Screen Lock Protection: Biometric and PIN protection for app access
Privacy & Safety Measures:
- Open Source Protocol: Independently audited and publicly verifiable code
- Minimal Metadata Collection: Only essential delivery information stored temporarily
- No Message Content Access: Signal cannot read your messages or listen to calls
- Safety Number Verification: Cryptographic verification to prevent man-in-the-middle attacks
- Relay Calls: Voice calls routed through Signal servers to hide IP addresses
- Registration Lock: PIN protection prevents unauthorised account takeover
Anonymous Setup: The pre-configured blank account allows immediate secure communication without identity verification, making it ideal for journalists, activists, and professionals requiring operational security from day one.
You may optionally register your own Signal number later or continue using the blank account for high-anonymity communication.
Threema License - Swiss-Grade Privacy Protection
Every Fortress Phone includes a lifetime Threema license, providing access to one of the world's most secure messaging platforms. Developed in Switzerland under strict privacy laws, Threema offers uncompromising security without requiring any personal information.
Advanced Security Features:
- End-to-End Encryption: All messages, calls, and files encrypted with NaCl cryptography

Why Threema: Unlike other messaging apps that collect metadata or require phone numbers, Threema is designed for true anonymity. It's trusted by government agencies, journalists, and privacy advocates worldwide for its uncompromising approach to digital privacy.
Premium VPN Service - Military-Grade Encryption & Privacy Protection
Every Fortress Phone includes a full 12-month subscription to a premium VPN service, one of the world's most trusted and security-focused VPN providers. Operating under strict European jurisdiction with a verified no-logs policy and independent security audits to verify privacy claims.
Advanced Encryption Standards:
- WireGuard Protocol: State-of-the-art VPN protocol with ChaCha20 encryption
- AES-256 Encryption: Military-grade encryption for OpenVPN connections
- Perfect Forward Secrecy: Each session uses unique encryption keys
- DNS Leak Protection: Prevents DNS queries from bypassing the VPN tunnel
Privacy focused:
- No-Logs Policy: Zero storage of user activity, connection logs, or metadata
- Anonymous Accounts: No email or personal information required
- RAM-Only Servers: All servers run diskless to prevent data persistence
- Owned Infrastructure: Provider owns and operates their own servers
Integrated with VPN Kill Switch Protection:
Your Fortress Phone's VPN Kill Switch works seamlessly with the included VPN service to ensure that if your VPN connection ever drops unexpectedly, all internet traffic is immediately blocked. This prevents any data from being transmitted over an unencrypted connection, maintaining your privacy even during connection failures. The kill switch monitors your VPN connection in real-time and acts as a failsafe against accidental data exposure.
In-House Wipe App - Protection Beyond the Cloud
To further defend against physical seizure tactics, we've developed a custom offline wipe application that is pre-installed on every Fortress Phone. Unlike traditional solutions that rely on remote access, our app functions autonomously. If the device remains offline for a user-defined amount of time, it will automatically trigger a secure wipe.
This makes it highly effective against attempts to block remote commands using Faraday bags or RF shielding, ensuring your data is destroyed even if the device is taken offline.
Advanced Emergency Safeguards - Preconfigured and Customizable
The Fortress Phone also includes automated protections tailored for high-risk users:
- Auto-Wipe Triggers: Wipes data if not unlocked for 14 days, if connected to a data USB while locked, or after 10 failed passcode attempts.
- Scheduled Auto-Reboot: Automatically reboots every 8-12 hours to refresh the secure environment.
- VPN Kill Switch: Prevents data exposure by cutting all traffic if the VPN disconnects.
What's Included with Your Device:
- 12 Months of Premium VPN Service
- Threema Secure Messaging License
- Pre-Configured Signal Account (Optional)
- Personalized Setup and Configuration

Privacy Phone vs Normal Smartphone: The Critical Difference
Normal Smartphone
- ✗Constant surveillance: Apps track location, contacts, browsing habits, and personal data 24/7
- ✗Vulnerable to exploitation: Standard Android/iOS lacks hardened memory protection and advanced exploit mitigations
- ✗Data harvesting by default: Google/Apple services collect telemetry, usage patterns, and personal information
- ✗Limited permission control: Apps often get broad access to sensors, network, and personal data
- ✗No emergency protection: No duress codes, auto-wipe features, or offline protection mechanisms
- ✗Carrier bloatware: Pre-installed apps with system-level access that can't be removed
Fortress Phone
- ✓Zero tracking by design: No Google services, no telemetry, no data collection - complete digital privacy
- ✓Hardened against 0-day exploits: Advanced memory protection, verified boot, and exploit mitigations protect against unknown vulnerabilities
- ✓Granular permission control: Network toggle, sensors toggle, storage scopes, and contact scopes - you control everything
- ✓Emergency-ready protection: Duress PIN, auto-wipe triggers, offline wipe app, and VPN kill switch
- ✓Clean, minimal system: No bloatware, no carrier apps, no unnecessary services - just secure, private functionality
What Makes This Difference Critical for Professionals
