Offline Disk Controller
The NAS dynamically manages the physical access to the data storage using multiplexers configured according to the policy enforced by an auxiliary computer, called Offline Disk Controller. Its security is guaranteed due to security domain segmentation and use of data diodes to control the information flow.
Uncompromising Security
Klein 4 is proud to present a next-generation Network Attached Storage system with hardware-enforced Data Loss Prevention, built on an innovative dynamic physical isolation mechanism, delivering enterprise-grade protection specifically tailored for European SMEs while maintaining minimal IT complexity and operational overhead.
Automated Cold Backups
Offline copies of your data remain secure in case of any cyber intrusion, even if the hacker gains unrestricted root-level access on all networked devices. Cold backups ensure data survivability against insider threats and sophisticated state-sponsored actors. Klein 4 NAS transforms cold backup creation from a labour-intensive and error-prone task into an automatic and continuous process.
Tamper Protection Mechanisms
The device features a range of tamper-evident and tamper-resistant hardening, from sensors embedded in the casing and security tags, through audio alarm, to phone notifications on admin access. This architecture ensures that any physical interference is immediately detectable and cannot occur without leaving verifiable evidence.
