your phone is the access system

Nexus replaces controllers, cards, LAN cabling and on-site servers with a biometric-secured smartphone and a cloud that never stops watching. No infrastructure to install. No hardware to outgrow.

the smartphone

More than a credential, it's the key, the commissioning tool and the network. Every phone carries its own encrypted, hardware-locked permissions, so the system grows one phone at a time: no controllers to buy, no infrastructure to outgrow.

    • Permissions cryptographically locked to your phone's hardware, always in sync - they can't be copied, shared or stolen

    • Secured by the biometrics you already use (Face ID, fingerprint, PIN)

    • Just present your phone - no app to open, no door to select

the cloud

The Nexus Cloud manages permissions, credential delivery, diagnostics, reporting and integrations - with no constant reliance on connectivity.

    • Phones and LiveLinks operate independently of the cloud

    • Events received in real time via multiple communication paths

    • Geographically redundant infrastructure - no single point of failure in the cloud

    • Hosted on Google Cloud Platform

security in front of the door, not behind it

Every permission is signed in the Nexus Cloud, locked to one phone's hardware, and refreshed continuously in the background. Permissions are time-limited by design - access keeps working through outages, and stale credentials simply expire.

    • No secrets stored at the door - nothing on-site worth attacking

    • Credentials are non-transferable: useless off the phone they were issued to

    • Every exchange happens over a freshly encrypted channel - recorded transactions are worthless

    • System-wide revocation, no revocation lists to distribute

Bi directional, zero missed events

It is called Swarm Intelligence: credentials travel down; events travel up - through whichever path is available at the time.

    • Mobile phones and site Wi-Fi act as gateways, allowing any node to reach Nexus Cloud through whichever path is available.

    • Every LiveLink can relay through the mesh, so communication is never tied to a single door or connection path.

    • Paths change automatically as connectivity changes, keeping events moving without relying on a fixed network connection.

    • Events are retained until they can be delivered, so a temporary loss of connectivity doesn’t become a lost event

the nexus mesh network

Every Nexus LiveLink and Nexus device communicates over a 2.4GHz peer-to-peer mesh, connecting to nearby devices instead of a central controller. The network expands node-by-node with virtually unlimited scalability and no home-run cabling.

    • Protocol layer: 2.4GHz mesh Wi-Fi for the network backbone.

    • Self-forming: Devices automatically join the mesh when enrolled via Bluetooth using the Nexus app, no manual network configuration required.

    • Resilient: With no single point of failure, the mesh automatically reroutes traffic if a device or connection is lost.

    • What it carries: Alarms, system upgrades, and buffered events that didn't transmit via smartphones

cryptography

Access decisions happen locally and securely - a zero-trust approach that verifies every transaction at the door, even without an internet connection.

    • AES-256 symmetric cryptography protects the LiveLink protocol, its long-term security does not depend on RSA or elliptic-curve cryptography.

    • Every LiveLink has its own cryptographic keys - keys are isolated to just one door, with separate keys for app communications, Permissions and activity records.

    • Keys are bound to the phone’s secure hardware, device-specific cryptographic material cannot be exported, and copying the app to another phone produces nothing usable.

    • Every door conversation creates fresh encryption keys - no two transactions share the same keys, so a recorded exchange cannot be replayed.

future-ready by design

Fully mobile and cloud-native, Nexus leverages the R&D budgets of Google and Apple - instant access to current and future device features like biometrics, location services and video, with no legacy hardware holding development back.
