Services

  1. Web development & design

    Clear interfaces, strong brand presence and well-structured content. We build websites and web applications that are easy to understand, fast and accessible.

  2. Visibility on Google

    Technical search engine optimisation, clear content architecture and data-driven analysis – for more visibility and qualified traffic, including in AI-powered overviews.

  3. Data privacy

    GDPR-oriented implementation and advice. Our data privacy experts bring experience as data protection officers, backed by our partnership with the law firm SMR-Legal.

  4. Cyber security

    AI-assisted fraud, supply-chain attacks and identity theft are on the rise. We rely on zero-trust principles, continuous monitoring and practical safeguards – and use penetration tests to check what is exposed.

02Free security check

How exposed is your website? We test it – free of charge.

A penetration test simulates a realistic attack on websites, applications or IT infrastructure. The goal is to find exploitable vulnerabilities before they are abused. Confidential, non-binding and with clear results.

  • Websites and web applications
  • Servers and IT infrastructure

Why free of charge? We want companies to be able to assess the security of their systems realistically – without high barriers to entry. You then decide whether and how to act.

How this website is secured
