Project Vajra

The Transparent
Shield.

A software-defined sidecar that wraps any existing system in quantum-safe encryption. Zero hardware changes. Zero application modifications. Deployable in under 15 minutes.

Full Solution Detail
Step_01
Legacy Device Sends

Tactical radio, banking switch, or satellite terminal sends data normally — zero changes required.

Step_02
Vajra Wraps Traffic

Hybrid KEM: X25519 + ML-KEM-768. AES-256-GCM tunnel. Both algorithms must be broken simultaneously.

Step_03
Backend Receives Safely

Receiving Vajra decrypts and delivers. Backend has zero awareness of the encryption layer.
