Albert Witteveen
IT Architect and Product Manager at National Police Netherlands

As an IT-architect and product manager with a focus on Cloud Native and Digital Transformation, Albert is currently working towards transforming from Shadow-IT to Showcase-IT.

The Dutch Police extensively use IT tools in daily operations, which has led to the emergence of shadow IT. However, these tools have proven to be crucial. The organization now perceives shadow IT as examples of what is needed, emphasizing the importance of proper management, security, and reliability. Instead of taking over these applications, the IT department has established a secure platform for field personnel to develop their own solutions, providing guidance on adopting modern DevOps practices.
This approach has resulted in the widespread implementation of cutting-edge techniques across the country.
