Purism, SPC (a Social Purpose Corporation based in San Francisco / Carlsbad, California) is an active US privacy and security niche maker, but no IEEE OUI was located for it — a negative finding. Its devices include the Librem 14 laptop, the Librem 5 / Liberty Phone Linux smartphone, mini PCs, and servers, all running PureOS. The reason for the negative finding is that, as a small niche maker, Purism appears to hold no dedicated OUI; its devices surface under their Wi-Fi or modem module vendors' OUIs — for example, an Atheros-class Wi-Fi adapter on the Librem laptops, and separate modem modules on the Librem 5. For triage, a Librem device will typically present its Wi-Fi module vendor's OUI, not a "Purism" OUI — so do not expect to fingerprint Purism hardware by OUI alone.

- Negative finding. As a small niche maker, Purism appears to hold no dedicated OUI; its devices surface under their Wi-Fi/modem module vendors' OUIs (e.g., Atheros-class Wi-Fi on Librem laptops, separate modem modules on the Librem 5). The IEEE registry publishes no assignment dates, and no Purism block was located. [Likely]
- Related vendors
- module/chipset vendors (Atheros/Qualcomm-class, Redpine-class) supply the actual MACs
- Analyst note
- A Librem device will typically present its Wi-Fi module vendor's OUI, not a "Purism" OUI — do not expect to fingerprint Purism hardware by OUI alone.
