As of 2025, implementation of the updated BIO2 (Baseline Information Security for the Dutch Government, version 2) will become a statutory requirement for many Dutch public sector organizations. This includes entities seeking to modernize their IT landscape through public cloud adoption—without compromising on security posture or compliance with regulatory frameworks.

BIO2 introduces approximately 200 tactical-level government-specific controls. These high-level controls must first be translated into operational security measures prior to implementation. This step is often cited as a key implementation challenge for government entities.

This blog presents a 10-step roadmap with best practices for effective BIO2 implementation in public cloud environments, based on real-world experience with AWS migrations in the Dutch public sector. The approach is cloud-agnostic and also applicable to platforms such as Microsoft Azure and Google Cloud Platform.
