Who We Are

Ex0-SyS is a Swiss company exclusively focused on the creation of new technologies, including ethical processing and digital data security.

By going back to the beginning of known concepts and projecting one’s mind outside of the box (notion of scales), one will access what remains invisible to those who do not follow this fundamental principle.

That is how we create technological solutions based essentially on the reordering of the initial conditions forming the basis of all information systems known to date.

Anything is possible as long as one isn’t aware that it’s impossible.

The 10 unique methods for innovation

  • Learn, to acquire Knowledge and invent
  • Understand, to acquire Science and create
If reordering the information to its fundamental state allowed a definitive answer to certain known technical challenges, which method would one choose ?

Our objectives

Our objectives are the security and protection of data transmission systems and of the personal data of users. Our tools are designed to combat global electronic surveillance that interferes with our private and professional lives, everywhere, at any time and without our knowledge.

Our values

Our values can be summed up in two words: freedom and responsibility. Freedom to keep control of all our personal information. Responsibility to assume and account personally for our actions without being responsible for the injustices of others or produced by a power system we have not chosen, but which is unfortunately admitted by the silent majority. We oppose a public order based on a hierarchical system, which obliges individuals to submit to unlimited permanent control. Our IT tools are created to allow users to maintain control over individual freedoms which are specific to the right of everyone. Our mission: to prevent our countries’ governments from completely perverting and transforming the whole reality of digital information into a fully Huxley world.


As a high-tech company, especially one that is focused on security, we need to build a trustworthy, authentic and sustainable relationship with our customers.

Therefore Ex0-SyS is committed to the following five fundamental principles:

  • Trust
  • Transparency
  • Security
  • Utility
  • Swiss Quality
Five commitments for the best personal data protection policy for everyone.
