The OEM model
Strengthen the OEM ecosystem. Never displace it.
PSG's technology-partner model strengthens the OEM ecosystem with an embedded trust layer; it does not displace it. PSG licenses its technology to OEMs and follows a Modular Open Systems Approach: an open architecture with standards-based protocols, a modern API, reference designs and third-party application hosting.
The DESI Controller is the practical starting point. Small enough to insert into an existing device, it gives readers, locks and sensors a cryptographic identity. Manufacturer-signed authentication lets end users verify genuine devices, blocking counterfeits, firmware modified en route and swapped hardware.
