A VPN for data that has to stay secret for years, not months.
Quantum computers will break the RSA and elliptic-curve encryption behind today's VPNs. Attackers already know it — they're recording encrypted traffic now to decrypt it later. QrypticTunnel seals your traffic with NIST-standardized post-quantum cryptography, so what's private today stays private after quantum arrives.
Harvest now, decrypt later
An attacker doesn't need a quantum computer today. They only need to record your encrypted traffic now — and wait.
When a cryptographically-relevant quantum computer arrives, Shor's algorithm breaks the RSA and elliptic-curve key exchange that protected that traffic. Everything captured is decrypted in retrospect. A strong data cipher like AES-256 doesn't save you — the session key was handed over using quantum-vulnerable key exchange.
Switch between the two — that gap is the whole product.
The migration has already started
Post-quantum isn't a future research topic. Standards are finished, deadlines are set, and India's regulators are actively mapping the sector's exposure.
NIST finalizes the first post-quantum standards
ML-KEM (Kyber) for key exchange, plus ML-DSA and SLH-DSA for signatures — the algorithms QrypticTunnel is built on.
Transition begins; RBI mandates .bank.in
US federal agencies start their PQC migration. India's banking sector moves onto a dedicated, controlled domain — the groundwork for stronger cryptographic requirements.
RBI constitutes the Q-SAFE committee
An expert panel to map the financial sector's cryptography through a Cryptography Bill of Materials (CBOM), assess crypto-agility, evaluate the maturity of vendor tools, and recommend a quantum-safe roadmap. Its report is due within six months.
RSA and elliptic-curve cryptography begin deprecation
Under NIST's timeline, today's public-key cryptography starts being phased out — and disallowed entirely by 2035.
Mosca's inequality: if the time your data must stay secret, plus the years it takes to migrate, is longer than the time until a quantum computer arrives — you are already too late to start.— Dr. Michele Mosca, on planning the quantum transition
A VPN built to outlast quantum
QrypticTunnel replaces the quantum-vulnerable key exchange inside a normal VPN with NIST-standardized post-quantum cryptography — using a hybrid design, so you're never less secure than today's best classical encryption, and you're protected against tomorrow's quantum threat.
Sovereign, and simple to run
The hard cryptography is invisible to your users. What they get is a normal-feeling VPN; what you get is control of the entire post-quantum PKI.
Enroll
Each user is issued a post-quantum identity by a privilege-separated certificate authority. The web dashboard validates requests but can never read the CA key — the signing happens in isolation.
Connect
One-time token, one click. The client establishes a post-quantum tunnel: ML-KEM key exchange, hybrid Falcon authentication, TLS 1.3 — negotiated automatically.
Stay sealed
All traffic runs inside the tunnel under AES-256-GCM. Certificates can be revoked instantly, and the full issue → deliver → revoke lifecycle is yours to run and to prove.
Aligned with where the regulation is heading
Regulators haven't finished writing the rules — but the direction is clear, and QrypticTunnel is built to meet it.
Post-quantum key exchange plus a Cryptography Bill of Materials that maps directly to what the committee is asking the sector to produce.
Strong, auditable cryptography with append-only logging — the evidence you need for incident response and reporting.
Protects personal data against future decryption — precisely the harvest-now-decrypt-later risk the law's intent anticipates.
Uses the FIPS-standardized post-quantum algorithms — ML-KEM and Falcon — not experimental or proprietary schemes.

Sovereign post-quantum infrastructure, built in India
QrypticTunnel is built by a small, focused engineering team who believe the quantum transition is the most important — and most neglected — security migration of the decade.
India's regulators are moving. Most vendors aren't ready. And the sectors that matter most — banking, defense, healthcare, critical infrastructure — need encryption they can run themselves, under Indian jurisdiction, without handing their keys to a foreign cloud.
So that's what we build: standards-based, auditable, post-quantum encryption for organizations that can't afford to have today's secrets broken tomorrow. We started with the hardest part — a working post-quantum VPN, and the tools to assess and prove cryptographic posture — and we work hands-on with a small number of design partners rather than selling shelfware.
Standards, not black boxes
NIST algorithms and open tooling you can inspect — never "trust us, it's secure."
Sovereign by default
Runs on your infrastructure, in India. Your keys, your control, your logs.
Honest about the limits
We're clear about what we protect and what we don't claim. Credibility is the product.
Map your exposure, or pilot the tunnel
Whether you're just mapping your quantum exposure or ready to run a pilot, we'll give you a straight technical answer — not a sales pitch.
