About this vendor.

Updated  ·  Confidence: Likely  ·  3 sources  ·  How this page is checked

A MAC address starting with 08:B4:CF belongs to Abicom International, an active UK manufacturer of OEM wireless networking hardware. The prefix is typically seen on Wi-Fi bridges, routers, and access-point modules built for embedding into other companies' products.

Abicom International Limited (Companies House number 04358289) has operated in the UK since incorporating on 22 January 2002, registered for wireless telecommunications activities, IT consultancy, and engineering research and development. It sells OEM 802.11 bridge and access-point hardware alongside an outdoor point-to-point and point-to-multipoint radio bridge line branded FreeSpace Networks.

The IEEE MA-L registration lists Abicom's registrant address as The Old Grammar School, Market Drayton, Shropshire, while the current Companies House record shows a Kineton, Warwickshire office. That is consistent with the company relocating since the OUI was assigned, not with two separate companies.

No CVE, security advisory, or documented vulnerability tied to Abicom International or its FreeSpace Networks products was found as of a September 2026 search. This is a sourced negative rather than a confirmed clean bill: the absence of a public CVE does not mean the hardware has been independently security-tested.
