Prevent security risks
Prevention is your first line of defense against security breaches. Your Synology server can be protected with intelligent solutions to stop attacks on your system and unauthorized user access.

System-level prevention
Create firewall rules, automatically block IP addresses with too many failed login attempts, and enable Account Protection to reduce the threat of brute-force attacks from untrusted clients.

User-level prevention
Add an extra layer of security if your credentials are leaked. Secure SignIn offers secure multi-factor authentication methods or convenient passwordless options. User-level permission settings can be applied to restrict access to files and features on a per folder or application basis.

Certified and trusted encryption
Synology DSM has been thoroughly tested and certified with FIPS 140 for cryptographic modules, as well as OpenChain 2.0 and 2.1 for open source compliance. Industry-standard AES-256 encryption is also used to keep your files secure.
Beat the security bugs
Your security is our priority. We work with and reward security researchers who highlight newly discovered vulnerabilities through the Bounty Program. The Synology Product Security Incident Response Team (PSIRT) will investigate and publicly report these while you can feel assured that your NAS will receive firmware and software updates for up to five years.
