Manage all your documents, photos, and other files, back up applications and devices, or protect your assets with professional video surveillance.

Private Cloud for Seamless Data Access

    • Streamlined File Management and Collaboration
      Store, sync, access, and share data from any device, wherever you are. Work seamlessly between different platforms and devices, and access your files through mobile apps, desktop clients, and a browser-based interface. Quickly and easily roll back files in case of accidental deletion, mistakes, malware, etc., with versioning.

    • A Private Photo Storage and Management Solution
      Effortlessly back up and organise photos, videos, and other visual assets using intuitive management tools. Automatically organise your content into albums and create secure share links for stakeholders and teammates.

    • Boost Team Productivity With Collaborative Tools
      Enhance workplace collaboration with Synology's productivity solutions. Create, edit, and share documents across teams in real time. Host an on-premises mail server to provide web-based email access while maintaining full data ownership. Additionally, stay connected through secure one-on-one chats, public channels, encrypted private channels, and group conversations.

Multi-Site Synchronisation to Empower Global Workflows

    • NAS-to-NAS Synchronisation
      Improve workflow efficiency and team alignment across data sites with automatic one- or two-way site-to-site syncing. Files and folders are kept up-to-date across sites, so everyone stays aligned, whether at home, in the office, or across different branches — all while maintaining full control of your data.

    • Cloud-Powered Multi-Site Syncing
      Empower global workflows with high-speed access to data from anywhere in your network. Our hybrid cloud solution caches frequently used files locally for rapid access, while less frequently accessed data is stored in the cloud, reducing your on-site storage requirements.

    • Sync to Public Cloud Providers
      Automatically keep data in sync between Synology NAS and major cloud providers, including BackBlaze B2, Dropbox, Google Drive, and Microsoft OneDrive. Multiple protocol support, client-side encryption, and customisation sync and bandwidth controls enable efficient storage management across various platforms.

      Consolidate and automate backup tasks for PCs, file servers, VMs, SaaS applications, and more. Administer device backups remotely through a centralised portal and quickly restore specific files or entire devices to keep your business up and running. Take advantage of built-in backup solutions designed to protect your data with seamless 3-2-1 backup configurations.

    • Comprehensive and Flexible Synology System Backups
      Protect all data, applications, and configurations on your Synology systems with comprehensive scheduled backups, including bare-metal backups, to local and remote servers, external drives, or cloud storage destinations, including Synology C2 Storage.

    • Tamper-Proof Protection With Immutable Snapshots
      Safeguard critical LUNs and shared folders with automated immutable snapshots backed by custom retention policies. Built-in support for offsite replication further ensures robust business continuity.

Smart Surveillance

      Protecting your business has never been easier, with centralised management, support for over 8,700 IP camera models, and remote monitoring and playback. Synology’s scalable video management system provides all the tools you need for live monitoring, investigation, management, and backup.

    • Dual Recording to the Cloud
      Secure your surveillance footage with robust cloud backup that supports end-to-end encryption. Synology's cloud-based surveillance backup solution safeguards your Surveillance Station recordings, allowing you to access, view, share, and download footage through a convenient web portal. Ensure your data remains available even if your on-premises system is compromised.

Versatile Testing Platform

Create a versatile environment for application testing and evaluation, supporting Docker containers and virtual machines. For package and security testing, Virtual DSM acts as a dedicated test environment, ensuring isolation between applications, systems, and data.

Centralised Monitoring and Management
