Robust and Secure

Global LTS encryption technology provides multiple security strategies combining proactive and protective measures to meet the data security needs of different organizations.

Multiple Security Technologies to Protect Enterprise Data

Creates snapshots of the entire file system on the TNAS device, preventing data loss caused by accidental operations or ransomware attacks.

Sets snapshot policies for shared folders or iSCSI LUNs, enabling rapid data restoration after a disaster.

Write Once, Read Many – files cannot be deleted, modified, or renamed. Prevents data from being accidentally altered or tampered with. Suitable for specific applications such as court cases, medical records, financial securities, and corporate financial data.

SPC ensures that all executable programs running in the system are legitimate and authorized by the user, thereby enhancing system security and reducing the risk of user data being attacked by hackers or ransomware.
