What I can do for you
From strategy to hands-on design, I work on the parts of IT where security and architecture meet.
Security Architecture

- Security reference architectures
- Risk, governance & compliance (NIS2, ISO 27001, GDPR)
Solution Architecture
End-to-end design of Microsoft-based solutions, from landing zones to workloads, with security built in from day one.
- Azure landing zones & governance
- Microsoft 365 & Defender
- Power Platform solutions
- Cloud migration & modernisation

About
Hi, I'm Dieter Vandebon
I'm a certified information security professional with more than 15 years of experience, and the founder of Vandebon Solutions. My background spans network security, security architecture and solution architecture, with deep expertise in the Microsoft ecosystem.
I like to connect strategy with technology: I can talk to the board about risk and governance, and the next day work through a firewall design or an Azure landing zone with the engineers. Clients get one consultant who covers both.
