Tempered

Tempered's Airwall product remains actively marketed under its own brand as of 2026, four years after the Johnson Controls acquisition, and has been integrated into JCI's OpenBlue platform, but there is no evidence of a fast, independent product release cadence since being absorbed into a much larger parent.

Airwall's Host Identity Protocol-based architecture is a real, previously independently deployed technology in critical infrastructure and IoT environments, and it continues to operate with a dedicated product site and marketing presence rather than being fully dissolved into JCI's broader portfolio.

The most significant momentum event was the June 2022 acquisition by Johnson Controls itself; since then, public visibility has been limited mostly to being referenced as a component of JCI's OpenBlue zero trust strategy rather than showing independent growth signals.

Using Host Identity Protocol, an IETF standard-track protocol originally developed at Boeing, to create cloaked, identity-based micro-segmentation is a genuinely different architectural approach from traditional VLAN- and firewall-based network segmentation, particularly valuable for legacy OT and building-automation devices that cannot be natively secured.

Host Identity Protocol is a real, standardized technology with credible origins, and Tempered built a customer base in critical infrastructure prior to acquisition, but no independent post-acquisition case study, breach-prevention data, or third-party evaluation specific to Airwall under Johnson Controls ownership was found.

IT/OT convergence risk and zero trust segmentation for building automation and industrial control systems are active, growing concerns for CISOs responsible for converged physical-cyber risk, and Johnson Controls' massive installed base of building systems gives Airwall real distribution relevance in that space.
