The Stichting Internet Cleanup Foundation has the goal:

To increase confidentiality, integrity and availability (CIA) of information on the internet and everything related to this subject in the broadest sense.

The foundation tries to attain this goal by:

  1. measuring the quality of CIA.
  2. supporting the creation of measurement tools that allow for independently measuring CIA.
  3. communicating the results and goal of the foundation at conferences and via (internet) media.
  4. increasing accessibility of (strengthening) CIA and related subjects.
