1. Implementation Delays in EU Cybersecurity Rules

A significant number of EU member states are yet to meet the implementation deadline for the Network and Information Security Directive (NIS 2), raising concerns among critical sectors like water provision. The directive, which aims to enhance cyber resilience across key industries such as energy, transport, banking, and digital infrastructures, requires entities to report serious incidents within 72 hours. The varying pace of adoption across countries like Germany, the Netherlands, and Ireland is creating a patchwork of regulations, complicating compliance for businesses operating across these markets.
