As building systems join the corporate network, they inherit its threats — but rarely its defences. We advise on securing the convergence of operational and information technology: segmentation strategy, hardening standards and monitoring requirements — so a compromised sensor can never become a compromised building. We define the standard and audit against it; your IT and controls teams apply it.
Scope of work.
Segmentation strategy
A clear design for separating OT and IT, with controlled, monitored crossings rather than flat, open networks.
Hardening standards
A defensible configuration baseline for controllers, gateways and supervisors — for your team to apply.
Secure remote-access design
A specification for encrypted, authenticated, audited remote engineering, without exposing plant to the open internet.
Security audit
An independent review of the delivered system against the agreed baseline, with prioritised findings.
Edge to headend, by design.
Tridium Niagara's cyber-secure connectivity and role-based access inform the secured-headend design, while Milesight's LoRaWAN edge — physically and logically separate from IP networks, with end-to-end encryption — keeps the sensing layer off the attack surface entirely.
Milesight
LoRaWAN sensors, IoT gateways and controllers that capture the building's reality — air quality, occupancy, energy, leaks — with long range, ultra-low power and end-to-end encryption. Wireless deployment reaches spaces traditional cabling never could, economically.
Tridium Niagara
The open, vendor-neutral software framework that normalises data from nearly any device or protocol — BACnet, Modbus, OPC UA and beyond — into one model. The control engine and supervisory layer where the building is integrated, visualised and operated as a whole.
The engagement.
Assess
Map the current OT/IT boundary and find where it leaks.
Specify
Define the segmentation, hardening and access standards to apply.
Audit
Independently review the implemented controls and report what still needs attention.
