ArchitectureHow security and trust is built.
One reference architecture under every deployment: the layers of a site, the protocol functions this platform relies on, and the evidence that travels with every observation.

Monitoring, incident response and governance
In Security and trust, the monitoring, incident response and governance layer holds incident response, security monitoring and logging and coordinated vulnerability disclosure, each drawn against the standard it follows. Preparing, detecting, containing, recovering and learning, tied to risk management. Central collection and correlation of device, network and application events.
The problem
Every node proves what it is
This page shows how Security and trust is put together, layer by layer, from the instrument to the record. Hardware-rooted identity and attestation at every join, PKI, secure boot and signed updates, segmentation between nodes, tenants and sites, operational-technology and wireless security, monitoring and response, and the move to post-quantum keys, planned before it is forced.

Monitoring, incident response and governance
In Security and trust, the monitoring, incident response and governance layer holds incident response, security monitoring and logging and coordinated vulnerability disclosure, each drawn against the standard it follows. Preparing, detecting, containing, recovering and learning, tied to risk management. Central collection and correlation of device, network and application events.
Architecture · Security, identity and trust
Zero trust and network security
In Security and trust, the zero trust and network security layer holds zero trust architecture, workload identity and port-based access and link encryption, each drawn against the standard it follows. No implicit trust from network location; each request authenticated, authorised and logged.
Architecture · Security, identity and trust
Device identity and attestation
In Security and trust, the device identity and attestation layer holds Trusted Platform Module, DICE layered identity and secure device identifiers, each drawn against the standard it follows. A hardware root of trust that holds keys, measures boot and signs attestation evidence.
Architecture · Security, identity and trust
PKI, secure boot and updates
In Security and trust, the PKI, secure boot and updates layer holds certificate profiles, automated certificate enrolment and revocation and status checking, each drawn against the standard it follows. X.509 certificate and revocation list profiles used across devices and services.
Architecture · Security, identity and trust
Privacy and data protection
In Security and trust, the privacy and data protection layer holds canadian privacy law, international privacy law and privacy information management, each drawn against the standard it follows. Federal and provincial rules for personal information collected by sites and services.
Architecture · Security, identity and trust
OT security and software supply chain
In Security and trust, the OT security and software supply chain layer holds industrial security programmes, system and component security levels and secure development lifecycle, each drawn against the standard it follows. Security management system for asset owners of control and monitoring systems.
Architecture · Security, identity and trust
Keys, cryptography and post-quantum migration
In Security and trust, the keys, cryptography and post-quantum migration layer holds key management lifecycle, hardware security modules and key management interfaces, each drawn against the standard it follows. Generation, distribution, rotation, backup and destruction of keys. Validated modules that hold root and signing keys.
Operations
Every node watched, every incident closed
Nothing on a network for Security and trust runs unwatched: the console shows each node’s state, plan and evidence. An incident for Security and trust begins with an alert that carries its data and a runbook, and ends only when the operator has recorded the cause and verified the fix.
Updates
Updates in rings, with rollback
Software for Security and trust is released in rings, so a fault shows on one canary site long before it could reach the whole fleet. A ring for Security and trust goes ahead only on health and data completeness, and a failed gate rolls each node back without anyone travelling to site.
Architecture · Security, identity and trust
5G and wireless security
In Security and trust, the 5G and wireless security layer holds 5G system security, network product security assurance and open RAN security, each drawn against the standard it follows. Authentication, key hierarchy, subscriber privacy and network domain security for 5G.
What you get
Open where it can be, contracted where it must be
What is open for Security and trust is free: the protocol, the methods and the open data can be used and built on by anyone. What must be contracted for Security and trust, sites, fleets, managed operations and data tiers, Nexus Observatory Inc. delivers at a price per site and per fleet, with service levels in numbers.
Next step
Security and trust, planned with you
Tell us which layers of Security and trust you already run and which you want us to design and deliver. An engineer replies with a survey proposal, a design and a scope for Security and trust, and the plan grows from one site to the network you need.

From one instrument to the grid.
Every deployment is drawn on the same six layers. A typed contract sits at every boundary, so parts from different makers fit together.
- 01InstrumentThe sensor or radio that makes the measurement, with its calibration.
- 02NodeThe device that hosts instruments: identity, time, power and storage.
- 03SiteNodes in one place, on one mast or in one shelter, with their links.
- 04CellSites that share a backhaul, a power plan and an operator.
- 05ClusterCells run as one service, with one fleet plan and one evidence trail.
- 06GridClusters that federate across owners through the open protocol.
The protocol functions this platform relies on most.
02Trust and evidence
