Johnson Controls acquires Tempered Networks to bring zero trust cybersecurity to connected buildings worldwide...

Johnson Controls (NYSE: JCI), the global leader for smart, healthy, and sustainable buildings, today acquired zero trust cybersecurity provider – Tempered Networks, based in Seattle, Washington. Tempered Networks has created ‘Airwall’ technology, an advanced self-defence system for buildings that enables secure network access across diverse groups of endpoint devices, edge gateways, cloud platforms and service technicians. It represents a step-change in operational technology built on secure transmission pipelines to ensure buildings data exchanges and service actions can only take place between people and devices that are continuously authenticated.

The acquisition gives Johnson Controls the capability to provide zero trust security within the fabric of its OpenBlue secure communications stack, advancing its vision of enabling fully autonomous buildings that are inherently resilient to cyberattack. 

How Airwall Works

Tempered Networks Airwall technology uses the Host Identity Protocol and a cloud-based policy orchestration platform to create new overlay networks built on encrypted and authenticated communication. The policy manager (a.k.a. the conductor) enforces configured digital policies that control connections within the cloaked overlay system. The default position for the policy manager is ‘zero trust’, i.e., only allowing connections between continuously authenticated and authorised entities. Once a communicating device authenticates itself correctly, an encrypted tunnel is created through which data flows. The advantages of this cybersecurity technique are as follows:

▪      The creation of an always-on and software-defined security perimeter protecting device-to-device, device-to-cloud and device-to-user interactions.

▪      Airwall achieves this by using Host Identity Protocol to create a cloaked and micro-segmented network which overlays a building’s existing network infrastructure, making the solution also highly cost-effective.

▪      A new level of authentication for connected building systems is created, allowing for greater system automation of functions such as heating and cooling, lighting, security and airflows.

“When it comes to buildings, we must create easily implementable cybersecurity defences as we’re often dealing with critical infrastructure, including assets such as data centres and hospitals,” said Vijay Sankaran, vice president and chief technology officer, Johnson Controls. “Tempered Networks Airwall approach is purpose-built for our sector as it’s designed around principles of zero trust, securing device communications as data moves between devices and the cloud – so enabling remote building optimisation in the most trusted way possible.”

Technology Integration

Tempered Networks Airwall technology is being integrated into Johnson Controls OpenBlue platform which is increasingly recognised as a leading smart building software platform with advanced AI-enabled building management capabilities[1]. OpenBlue provides a flexible computing approach for converging building technologies and making those technologies more insightful, powerful, and optimised through edge AI and through full machine learning in the cloud. The ultimate goal is to make all buildings smarter, healthier and more sustainable.
