Secure Remote Workforces
Crux VPN is built for a world where work doesn’t happen behind a firewall. Whether users are on the move, working from home, or operating in untrusted environments, Crux VPN provides secure, seamless remote access without the operational drag of legacy VPNs or certificate-based systems.
Instead of relying on static credentials, hardware tokens, or brittle key infrastructure, Crux VPN dynamically provisions short-lived, symmetric keys to every trusted device — enabling quantum-safe, zero trust communications with minimal setup and no user intervention.
Problem
Traditional remote access solutions were never designed for the way we work today:
- Traditional VPNs are centralized, fragile, and dependent on fixed infrastructure.
- Hardware encryption devices are expensive, immobile, and hard to scale.
- Public-key infrastructure (PKI) introduces certificate sprawl, long-lived credentials, and complex revocation logic.
- Wireless and commercial networks are often considered untrusted — and unsupported.
All of this leads to security friction, increased costs, and a poor experience for users and administrators alike.
Crux VPN in action
Crux VPN securely connects users and devices across any network — Wi-Fi, LTE, 5G, or satellite — using ephemeral symmetric keys generated on demand. Keys are provisioned via an embedded broker (based on Arqit SKA-P), ensuring that no static credentials are stored, and no single point in the system ever holds enough information to compromise a session.
Access policies are enforced in real-time, and keys rotate automatically with every session, supporting continuous authentication and dynamic trust. The result is a system that’s lightweight, highly secure, and operationally invisible to the user.
Design highlights
- Crux-native authentication and key exchange — no certificates, no tokens, no manual provisioning.
- Symmetric key model built for post-quantum resilience and crypto-agility.
- Bearer-agnostic — works securely over any network, including low-trust or bandwidth-constrained links.
- Split trust by default — no party holds a complete picture of the keying process.
- Pluggable trust fabric — supports a variety of underlying key brokers, including Arqit.

When to use Crux VPN
Crux is ideal for teams and organizations that need:
- A secure access layer for hybrid or remote teams
- Post-quantum ready infrastructure without operational disruption
- Mobility and flexibility across devices, networks, and geographies
- A zero trust approach that doesn’t rely on brittle PKI
- Interoperability with both legacy systems and forward-leaning security models
