SAXA, Inc. — 2 prefixes (MA-L)

SAXA, Inc. is a Japanese office-communications and IP-telephony manufacturer that holds two IEEE MA-L blocks — 00:20:C1 and 00:02:2B — both registered to "SAXA, Inc." at the NBF Platinum Tower, 1-17-3 Shirokane, Minato-ku, Tokyo 108-8050, Japan. The company traces to the 2004 merger of two postwar telecoms-equipment makers, Tamura Denki Seisakusho (founded 1946) and Daiko Denki Seisakusho (founded 1938), both longstanding suppliers of public telephones and key-telephone systems into the NTT ecosystem; the merged firm listed on the Tokyo Stock Exchange (ticker 6675) and was renamed SAXA, Inc. in July 2024. SAXA's hardware is squarely enterprise/SMB office gear: business IP telephones (the IP NetPhone SX/SX II/SX III lines), PLATIA-series key-phone systems, UTM/VPN routers and security appliances, network media servers, and wireless desk phones. Much of it ships OEM — the PLATIA platform is resold by OKI as "CrosCore" — and the customer base is Japan-centric, anchored by NTT East/West and other NTT Group companies. For network-traffic work, a SAXA OUI on a LAN reliably points to internal corporate equipment: an office IP phone, a key-phone-system controller, a UTM/VPN gateway, or a wireless desk phone. No public CVEs attributed to SAXA-branded products and no known threat-actor tooling targeting them were found in this research pass, and the devices are unlikely to appear outside Japanese enterprise environments.

Allocated date

Unknown — IEEE publishes no OUI registration dates; no RIR/RDAP analogue exists for OUI assignments [Unknown] — the IEEE MA-L registry

Special note

SAXA hardware is Japan-market-centric office telephony / UTM gear; a SAXA OUI on a LAN indicates internal corporate equipment (IP phone, key-phone controller, UTM/VPN gateway, or wireless desk phone) [Likely] — https://www.saxa.co.jp/english/about/profile/group/

Analyst note

no public CVEs attributed to SAXA-branded products and no known threat-actor targeting found this pass; security relevance is asset-classification (the device is internal office equipment), not a known-vulnerable-class signal [Likely] — https://www.saxa.co.jp/english/about/profile/group/
