About us

Our story

The beginning

In 2018, Bruno and Sandrine set sail on a mission: reconcile intensive use of confidential data with zero compromise on security and privacy.  They quickly dived into the extraordinary capabilities of advanced cryptography, a deep tech, academic field, where mathematicians relentlessly push the limits of data security in complex environments.
Understanding the ins and outs of encryption might not be for everyone, but everyone can benefit from what the next generation of encryption has to offer. From state-of-the-art technology introduction to enterprise-grade, practical implementation, our team of experts will help you navigate the latest innovations in data security.
