Le The General Data Protection Regulation (GDPR) entered into force in May 2018. Organizations around the world are facing a dramatic increase in legal requirements to protect sensitive and private data. Companies that collect, process and store personal data and which infringe this regulation will face serious consequences. Although created by the EU, GDPR (General Data Protection Regulation) has a internationnale scope, covering the personal data of European citizens and providers wherever the data is distributed worldwide.

Our mission is to guarantee the protection of your data in the Cloud and within your Intranets. Difenso offers major groups, small companies and individuals an innovative and uniquely designed solution, easy to implement to protect all your shared data.

ACCELERATE YOUR BUSINESS AGILITY WITHOUT COMPROMISING YOUR DATA SECURITY...Cloud services all pose multiple vulnerability issues. Difenso has developed solutions so you can win back control over your data and ensure that no unauthorised third-parties can gain access to them.

The solution

Based on unique encryption keys, randomly generated to encrypt data and/or files and documents.

Thanks to an innovative principle of on-the-fly construction, Difenso stores no data, neither “text” nor “encrypted” data, nor even the keys used to encrypt/decrypt the data. The encrypted date becomes entirely inviolable: only their owners of authorised users can decrypt them.
