OUR MISSION

Securing the world before
quantum computers arrive

Quantum computers running Shor's algorithm will break RSA and ECC encryption — the foundation of most internet security today. QuantaShield exists to make the transition invisible. Post-quantum encryption, available to every team, right now.

Why it matters

The harvest-now,
decrypt-later threat

Nation-state adversaries are already collecting encrypted internet traffic today, with the explicit plan to decrypt it once quantum computers become available. Healthcare records, financial data, IP, and private communications — all at risk from data collected right now.

NIST finalised the first post-quantum cryptographic standards in 2024 — ML-KEM-768 (FIPS 203) for key encapsulation and ML-DSA-65 (FIPS 204) for digital signatures. QuantaShield ships these standards as a usable, zero-setup product.

You do not need to wait for the quantum threat to materialise. The time to migrate is before it arrives.

Our values

Principles we never compromise on

User-owned keys
Your private key is generated in your browser and never leaves your device. We are cryptographically incapable of accessing your data.
Zero server trust
Every cryptographic operation runs locally via WebAssembly. There is no server to compromise, no database to breach, no credentials to steal.
Open standards
We build exclusively on NIST-standardised algorithms — ML-KEM-768 (FIPS 203) and ML-DSA-65 (FIPS 204). No proprietary crypto, ever.
Full transparency
Every operation is logged locally. You know exactly what ran, when, and with what result. Export your audit trail at any time.
Quantum-resistant by default
Classical RSA and ECC will fall to sufficiently powerful quantum computers. Our entire stack is built post-quantum from day one — no migration needed later.
Private by design
We collect no telemetry, no usage analytics, no crash reports. The product works entirely offline. Your data is your business, not ours.
Our story

Built from the ground up

2024 Q3
Project started
QuantaShield begins as a proof-of-concept: can we build production-grade post-quantum encryption that runs entirely in a browser?
2024 Q4
QKnight v1
First working implementation of ML-KEM-768 file encryption in the browser using @noble/post-quantum and a WASM crypto layer.
2025 Q1
RepoShield launched
Dependency vulnerability scanner built on OSV.dev goes live. 8 ecosystems. AI-generated remediation. CycloneDX SBOM export.
2025 Q2
Platform expansion
Mobile app (Capacitor), Browser Extension (MV3), Desktop App (Tauri), and DevSecOps Agent all enter active development.
2025+
Enterprise & beyond
Team key management, encrypted cloud vault, SSO / SAML integration, and the Encryption Proxy for infrastructure-level post-quantum protection.
