The MA-L block 78:D3:ED is registered to NORMA, a South Korean cybersecurity company headquartered in Seongdong-gu, Seoul. The IEEE registry carries the address Achasan-ro 7na-gil, Seongdong-Gu, Seoul, KR 04795; NORMA's own English site gives 52, Achasan-ro 15-gil, Seongdong-gu, Seoul 04795 (Samhwan Digital Venture Tower) — the same district and postal code, consistent with a registry-vs-current-office difference rather than a conflict. Founded in 2011, NORMA builds defensive wireless and IoT security products: AtEar (a Wi-Fi/Bluetooth threat scanner and rogue-AP detector, sold as desktop software and an Android app) and IoT Care 2.0 (a hardware/software platform protecting APs, CCTVs, POS terminals, and unmanned kiosks). The company is a Nokia ecosystem partner with Korean government, military, and utility clients, and has since expanded toward quantum-resistant security products. Devices bearing this OUI are therefore network-security sensors and appliances, not commodity consumer networking gear. A common data trap: the "07 May 2021" date shown for this block on third-party tools like maclookup.app is a database artifact — IEEE publishes no OUI registration dates — so it must not be recorded as an IEEE fact. Note also that several unrelated entities share the "Norma" name (NORMA Group, Germany, industrial clamps; NORMA A/S, Denmark, a clinical-research CRO); the OUI holder is specifically NORMA Inc., Seoul.

- Analyst note
- this OUI marks legitimate institutionally-backed security hardware (Nokia partner; Korean government/military/utility clients; sovereign-fund investment reported 2024). Low supply-chain concern; no CVE/vulnerability disclosures against NORMA products found this pass.
