    Cubbit for Teams
    Cubbit for Teams is a SaaS distributed cloud storage that provides businesses with complete security. Thanks to the distributed zero-knowledge network, not even the service provider can access the uploaded files, meaning Cubbit goes beyond the facade of regulatory compliance. Cubbit for Teams reimagines the concept of security by providing an easy-to-use platform: zero-knowledge and end-to-end encryption protects the user as he saves, syncs and shares its data. Information can be accessed from anywhere at any time through the web-app, while employee permissions are managed with the click of a button. Files are shared with no size limit and unsecured email is replaced by Cubbit Private Links: a 100% secure sharing method that matches an encryption key to the folder. Relying on a distributed architecture instead of traditional data-centers allows Cubbit to be cost-effective and provide a significantly cheaper service than the competition. Plus, you will save CO2 per file stored.

    Kamzan

    Kamzan

    Kamzan

    Cloud suite for business digitization, collaboration and sharing. A Private Cloud dedicated exclusively to you. We create an ad-hoc technological infrastructure for each customer and separate from the others to minimize the risk of data-breach. The data is stored exclusively in the European Union, in a Data Center located in Germany which is part of the CISPE. All data is encrypted with a different key for each private cloud, just as the database on which the service is based is also encrypted. The encrypted communication protocol uses a unique TLS 1.3 certificate for each customer. A uniquely European supply chain and a contract in which we make it clear that profiling will never be carried out, that no data will ever be sold or transferred to third parties and that the intellectual and physical property of the data in their entirety is held by the client company.
