Johnson Controls Buys Tempered Networks
June 24, 2022
Johnson Controls acquired zero trust cybersecurity provider – Tempered Networks, based in Seattle, Washington. Tempered Networks has created 'Airwall' technology, an advanced self-defense 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.
terms of the transaction were not disclosed.
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 authorized entities. Once a communicating device authenticates itself correctly, an encrypted tunnel is created through which data flows.
advantages of this cybersecurity technique are as
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.
comes to buildings, we must create easily implementable
cybersecurity defenses as we're often dealing with
critical infrastructure, including assets such as data
centers 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 optimization in the most
trusted way possible."
Networks Airwall technology is being integrated into
Johnson Controls OpenBlue platform which is increasingly
recognized as a leading smart building software platform
with advanced AI-enabled building management
capabilities1. OpenBlue provides a flexible computing
approach for converging building technologies and making
those technologies more insightful, powerful, and
optimized through edge AI and through full machine
learning in the cloud. The ultimate goal is to make all
buildings smarter, healthier and more sustainable.
