Digi Távközlési Szolgáltató Kft. ('Digi') (electronic communication service provider)

Description

The company had infringed the principles of purpose limitation and storage restriction because its database contained a large amount of customer data which were no longer relevant for the actual purpose of collection and for which no retention period had been set. Furthermore, the NAIH pointed out that the defendant had not taken proportionate measures to reduce the risks in the area of data management and data security, arguing, inter alia, that it had not used encryption mechanisms.
