Summary

// what this is
34ED LLC DBA Centegix is registered to MAC prefix 38:53:19 in the IEEE OUI database. When a device's MAC address begins with 38:53:19, that block was registered by 34ED LLC DBA Centegix — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC beginning 38:53:19 indicates Centegix-assigned hardware, most likely a CrisisAlert badge or related access hardware; absence of this prefix does not rule out a Centegix deployment if a device uses a different radio module.

About this vendor.

A MAC address beginning 38:53:19 belongs to 34ED LLC DBA Centegix — doing business as Centegix — and most likely identifies a CrisisAlert wearable panic-button badge or a related piece of Centegix's crisis-alerting hardware, deployed in a K-12 school, healthcare facility, government building, or workplace.

The IEEE MA-L registry lists exactly one block under this registrant: 38:53:19, registered to "34ED LLC DBA Centegix" at 2120 Powers Ferry Rd, Suite 110, Atlanta, GA 30339, US. No companion MA-M or MA-S rows for this name were found in the local registry files, so this is a single-prefix vendor rather than a multi-block company.

Centegix is a real, operating Atlanta-based safety-technology company, founded around 2016-2017, whose flagship product is CrisisAlert: a wearable badge worn on a lanyard that uses LoRa long-range low-power wireless over a private managed network rather than Wi-Fi or cellular. On activation, a badge triggers a facility-wide alert with location mapping, strobes, and intercom or screen takeovers. Centegix reports deployment at 4,000+ locations, and independent press (the Atlanta Journal-Constitution) credited CrisisAlert with a role in the emergency response during a 2024 Georgia school shooting.

No CVE or NVD-recorded vulnerability is documented for Centegix or CrisisAlert as of an August 2026 search. As a life-safety and physical-security wearable, the device category is security-relevant by function, not by any known flaw.
