About Network and Information Security Directive
The updated EU cybersecurity directive that expands security requirements to a broader range of sectors and imposes stricter obligations on essential and important entities.
Network and Information Security Directive Impact on Telecommunications
Telecommunications providers face a triple regulatory burden under GDPR, NIS2, and the ePrivacy Directive. As providers of publicly available electronic communications services, they are directly subject to ePrivacy rules on communication confidentiality, traffic and location data processing, and subscriber data. NIS2 classifies telecommunications as essential digital infrastructure, requiring comprehensive cybersecurity risk management, incident reporting, and supply chain security. Telcos handle massive volumes of personal data — subscriber data, call detail records, location data, internet usage data — all subject to strict GDPR processing rules. Data retention laws add further complexity, with varying national requirements on retaining communications metadata for law enforcement.
