MAC Address Randomization and the Impact It Has on Network Operators and End-users

In this video, Santeri Kangas, the CTO of CUJO AI, talks about MAC address randomization and the issues it causes for network service providers.
Historically, MAC addresses used to be fixed and were used as device identifiers. They would identify the device manufacturer and the device model.
Nowadays, many devices randomize their MAC addresses by default. The frequency and triggers for rotating a MAC address depend on the device and can be rather unpredictable. The most notable move to randomize MAC addresses was made by Apple in late 2020, when all iOS and WatchOS models were set to randomize their MAC addresses by default. This impacted over 30% of all mobile devices.
This situation makes it difficult for network service providers to reliably manage many of their services, such as Wi-Fi steering, diagnostics, parental controls, and user journeys.
CUJO AI has recently released a patented AI-driven device identification solution that can detect, identify and categorize devices with high precision and without any impact to end-user privacy. This helps network providers deduplicate and unify their MAC address signatures and greatly enhances the granularity of their device inventory data.
