Tresorit

Tresorit provides a highly secure environment for you to store, sync, and share sensitive files without compromising on privacy. Unlike standard cloud providers, it uses zero-knowledge, end-to-end encryption, meaning only you and your intended recipients hold the keys to view your data. You can manage internal documents or collaborate with external partners while maintaining full control over who sees what and for how long.

You can access your encrypted files from any device, whether you are in the office or working remotely. The platform helps you meet strict compliance standards like GDPR and HIPAA by providing detailed audit trails and granular access permissions. It is designed for businesses that handle high-stakes information, such as legal firms, financial institutions, and healthcare providers, who need to guarantee data integrity at all times.
