About Wüstenberg IT

Wüstenberg IT specialises in the assessment and protection of IT systems for small and medium-sized enterprises (SMEs). Our focus is on technical depth, research-based methods and tailored solutions instead of off-the-shelf products.

About Lars Marcus Wüstenberg

I am Lars Marcus Wüstenberg, founder of Wüstenberg IT and a cybersecurity specialist with more than 15 years of experience. During my time at the University of Hamburg, I was involved in research projects on IT security and studied attack and defence mechanisms in complex systems in depth.

Today, I use this experience to support organisations in a practical way – from the technical analysis of individual systems to the structured improvement of their overall security architecture.

Team & network

Wüstenberg IT does not operate as an anonymous large provider but as a network of experts:

  • A small, well-coordinated core team
  • Long-term freelance specialists in specific areas of security
  • All selected based on experience, quality and trust

For you, this means access to the expertise of a seasoned security team without the overhead of a large organisation.

Our approach

  • Freelance expertise instead of pre-packaged products
  • Transparent communication and clear prioritisation
  • Alignment with BSI guidance and scientific sources
  • Recommendations that fit the reality of SMEs
