Synology DiskStation Manager (DSM) is the intuitive operating system that powers every Synology NAS, turning a simple storage device into a private cloud for your home or business. You can easily centralize your data, manage file sharing across different platforms, and set up automated backup routines to protect your most important digital assets. It provides a familiar, desktop-like interface in your web browser, making complex network configurations accessible even if you aren't a technical expert. Beyond simple storage, you can transform your hardware into a versatile hub for multimedia streaming, surveillance management, and team collaboration. Whether you are a creative professional handling massive 4K video files or a business owner needing a secure mail server, DSM offers the flexibility to scale. It solves the problem of fragmented data by bringing your photos, documents, and system backups into one secure, self-hosted environment that you fully control.

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.
