What is Spectre Solutions?

Spectre Solutions is your trusted partner to the most secure mobile experience available today. We offer Castrum OS, a next-generation hardened operating system built for Pixel devices, designed for professionals, businesses, and privacy-conscious individuals who demand total control, privacy, and security. Castrum OS runs without Google services, follows a strict zero-trust security model, and ensures your data stays yours.

Secure by Design

Built from the ground up for security, with advanced protections to safeguard your data against threats.
It features a hardened operating system, full data encryption, and verified boot protection. Advanced security mechanisms and privacy-focused firmware ensure that the user retains full control over the device — even in the face of the most sophisticated digital or physical intrusion attempts.

Zero-Trust & Absolute Privacy

Privacy-first architecture with no backdoors, ensuring complete control over your data.
Castrum OS enforces a Zero-Trust security model, ensuring that no system component is blindly trusted. With end-to-end encryption, permission control, and no hidden telemetry, your data remains private—shielded from surveillance, tracking, and unauthorized access.

Military-Grade Encryption

End-to-end encryption protects your data with the highest cryptographic standards.
Spectre Phone utilizes state-of-the-art encryption, including AES-256 for full-disk encryption and OMEMO for end-to-end encrypted communication. With secure key storage and no server-side message access, your private data stays confidential and inaccessible to third parties.

Proactive Defense

Advanced security mechanisms protect against unauthorized access, tampering, and forensic attacks.
Spectre Phone features a wipe password for instant data wipe, automatic reboot into before first unlock state for added security, and ten-attempt auto-wipe to prevent brute force attacks. With a Dedicated Device control centre (DCC), system integrity is enforced, and developer mode blocking prevents exploitation attempts.
