The OUI prefix C0:E0:1C is a single MA-L (MAC Address Block Large) registered to IoT Security Group, SL, a small Spanish company based at Calle Pez Dorado, 27, local 2, in Torremolinos, Malaga (postal code 29620). An MA-L block covers the full 24-bit-prefix range C0:E0:1C:00:00:00 through C0:E0:1C:FF:FF:FF — roughly 16.8 million addresses — so a device presenting a globally-administered MAC under this prefix maps to this one registrant. The company is a microenterprise: Spanish business registries record it as a Sociedad Limitada (Spanish LLC) with CIF B93747061, founded 2 April 2020 in the Registro Mercantil de Málaga, with registered capital of €3,000 and a headcount in the 1–10 range. Its declared CNAE activity is 6190 (other telecommunications activities), alongside wholesale trade of electronic and telecommunications equipment including routers — a profile consistent with a niche networking or IoT-security appliance OEM/integrator rather than a high-volume consumer manufacturer. Despite the "IoT Security" name, no public vendor website, product catalogue, or documented device line could be confirmed, so the specific device types behind this OUI remain unknown and are recorded as a sourced null rather than guessed. IEEE publishes no registration date for OUI/MAC prefix assignments, so no assignment date is claimed here; the "04 February 2022" date shown by some third-party MAC lookup tools is a database artifact, not an IEEE fact.

- Analyst note
- A globally-administered MAC under C0:E0:1C maps to this small Spanish telecom/networking firm. The "IoT Security" name and CNAE 6190 + router wholesale profile suggest a niche networking/security appliance OEM or integrator, but with no product documentation, no CVE history, and no public threat research mentioning this vendor, device classification stays uncertain.
