Microsoft 365 Security – Your Business Prepared

Introduction: why 2025 will be a turning point

Microsoft has announced that Microsoft 365 will make major security changes in 2025. Think of new RBAC (Role-Based Access Control) methods, stricter compliance tools and the phasing out of outdated modules. For Dutch companies, this not only means a technical migration, but also a strategic challenge: how do you guarantee continuity, compliance and security in one move?

Many SMBs, IT managers and C-level executives in the Netherlands are already wondering:

What does this mean for my Microsoft 365 environment?
How do I ensure I am compliant with AVG and NEN7510 in a timely manner?
What impact will this have on my employees and daily processes?

In this blog you will discover what the Microsoft 365 updates entail, what risks are involved, and how you, as a Dutch company, get maximum ROI from the mandatory changes.
