MAC address vendor

Primary prefix
00:14:84
Block
MA-L

Summary

// what this is
Cermate Technologies is registered to MAC prefix 00:14:84 and 1 more in the IEEE OUI database. When a device's MAC address begins with 00:14:84, that block was registered by Cermate Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Both OUI blocks (00:14:84 and 78:36:07) are standard, non-shared /24 registrations held directly by Cermate Technologies Inc., so a MAC beginning with either prefix can be attributed to this vendor without a shared-base caveat. No CVE or CISA ICS advisory naming Cermate was found as of a September 2026 search.

About this vendor.

Updated  ·  Confidence: Likely  ·  9 sources  ·  How this page is checked

A MAC address starting with 00:14:84 or 78:36:07 belongs to Cermate Technologies Inc., a Taiwan-based manufacturer of industrial human-machine interface (HMI) touch panels and operator panels.

The IEEE registry lists two separate MA-L (/24) blocks assigned directly to Cermate Technologies Inc., both keyed to the same address at 7F-1, No 168 Lien-Chen Rd., Chung-Ho Dist., New Taipei City, Taiwan. Holding two independent OUI blocks at one address is itself a substance signal beyond a single opportunistic registration.

Third-party sources describe Cermate as an HMI and communications-gateway manufacturer founded in the early 2000s. Its product line includes Windows CE-based touch panel PCs sold under the PX (advance), PT (enhanced), GX and PK (economy) series, along with touch monitors and serial-to-Ethernet adapters. Physical units from these lines are sold as used equipment on resale marketplaces, and the company carries a standard B2B directory footprint (Dun & Bradstreet, ZoomInfo, a Facebook business page).

No CVE, NVD entry, or CISA ICS-CERT advisory naming Cermate Technologies or a Cermate product was found as of a September 2026 search. That is reported as a sourced negative rather than a finding of a clean bill of security.
