Digital asset protection

Powered by Synology DiskStation Manager (DSM), Synology NAS offers advanced security measures to protect against sudden data loss and potential security holes. Learn more

• Security Advisor : Analyze system settings, password strength and network preferences, and remove any possible malware.
• AppArmor : A kernel-level enhancement that blocks malicious programs from accessing unauthorized system resources.
• AES 256-bit encryption : ncrypt shared folders and network data transmission to avoid unauthorized data access.
• 2-step verification : Prevent others from logging in to your DSM by generating a six-digit one-time password (OTP) on your mobile device.

Complete iSCSI and virtualization solutions

Synology iSCSI storage supports most virtualization solutions such as VMware vSphere, Microsoft Hyper-V, Citrix Xen Server, and OpenStack Cinder to enhance work efficiency. You can run and manage multiple virtual machines on Windows, Linux, or DSM using Virtual Machine Manager.
