Klein 4 is redefining data security at the physical layer, protecting the most valuable asset of every SME.
Our innovative solution to protect your valuable data. Built for the European SME market with uncompromising standards.
Data Loss Prevention enforced by physical isolation machanisms.
Air-gapped backups created automatically without human intervention.
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.
Ransomware and human error alike can bring business to a standstill by making
critical data
unavailable. When key files are deleted or otherwise made inaccessible, teams
scramble to
recover or recreate them.
Such
troubles are
prevented by restoring files from a physically air-gapped but frequently updated
copy,
ensuring Business Continuity and robustly mitigating any unexpected IT problems, no
matter
the source.
The device 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.
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.
The device is built specifically for European SMEs and shaped by over 100 in-depth customer interviews, with particular emphasis on engineering companies and creative agencies.
It integrates seamlessly with your existing workflows and systems, including Microsoft 365, enabling your team to maintain established processes while the device operates unobtrusively in the background.
The NAS can be accessed remotely via a secure, end-to-end encrypted proxy connection through the K4OS platform, allowing you to reach your files from outside the office.
The NAS supports role-based permissions at both user and group level, allowing you to precisely control who can view, edit, or share specific folders. All administrative access is logged, and suspicious activity is flagged, helping you detect, contain, and respond to potential security incidents.
