Ciphertex OS

CiphertexOS offers a wide range of storage and networking features for SMB and enterprise IT administrators.


Storage Administration for IT Professionals

Free, secure, and intelligent, CiphertexOS is the go-to NAS solution for serving data
on-premises and moving data between locations.

Data Security Is What We Do

CiphertexOS combined with the Ciphertex Protect AES 256-bit hardware encryption key delivers top-level cybersecurity at the edge - without the decryption passcode, nobody can access your system.

Administration Made Easy

The CiphertexOS dashboard gives administrators an in-depth overview of the SecureNAS system’s current status, performance, and storage usage.

USB Port Firewall

Administrators have the ability to easily enable USB port blocking and to prevent unauthorized system access. When enabled, SecureNAS will ignore all communication from all external USB devices.

IP Web Interface

Administrators can connect over IP on LAN. The intuitive web-based graphical interface of CiphertexOS offers an easy-to-use tree-structured menu to access advanced services and settings.

Your Security Is Key

Encryption Key Management:

  1. Ciphertex-Protect® Encryption Key is a FIPS 140-2 Level 3 validated hardware encryption module that encrypts network shares at the filesystem (or volume) level.
  2. To activate the key, it must be paired via the web GUI (administrators have the option to set a passphrase).
  3. After pairing, encrypted data residing on the Ciphertex SecureNAS® volume cannot be accessed unless the Ciphertex-Protect® key is inserted into the USB Type-C port on the front of the server.
  4. If the administrator designated a password, it must also be entered to unlock the volume.
  5. Key Server – CiphertexOS supports centralized storage and management of the encryption key(s) on any key server supporting KMIP.

Data At Rest Management

Data is protected with the CiphertexOS implementation of the US government’s Advanced Encryption Standard (AES). Data cannot be accessed by unauthorized persons even if the server or its disks are lost or stolen.

Security At Scale

The Ciphertex OS platform provides many options for architecting secure storage environments for companies of any size - from SMBs to enterprises to governmental agencies.

Data Transfer Encryption

Active Directory integration gives administrators more flexibility when using the SecureNAS® in a complex multi-user network environment.


Schedule daily or weekly scans, upload virus definitions, and quarantine infected files.

Account Management

Admin Account

CiphertexOS defines a permanent administrator account to ensure login access to your SecureNAS at all times - the password can be changed after NAS setup.

Users And Groups

Strong data security involves setting up other admin, super user, user or group accounts and defining permissions for network shares and volume access.

ADS Integration

Strong data security involves setting up other admin, super user, user or group accounts and defining permissions for network shares and volume access.

Storage And Sharing

Ciphertex OS
ZFS Implementation

The CiphertexOS implementation of OpenZFS provides a simplified way of managing storage pools, filesystems, and redundancy.


ZFS eliminates the user maintenance tasks that traditional RAID implementations require. It is self-healing and highly resistant to data loss as opposed to standard RAID systems.


A highly optimized version of block based data deduplication to reduce storage space consumption.


Network sharing of volumes on a per user or group basis supported by both Windows Active Directory and local Linux authentication.


Share filesystems over the network that can be accessed by designated FTP clients.


Quick and easy setup of NFS shares.

LFTS Phoenix

Allows users to collaboratively read, write, and share content directly in an HTTP web server client.

ISCSI Target

Reserve sections of your storage pools so that users can mount and access volumes (drives) locally on their client. ISCSI target uses CHAP authentication.

Portable USB

CiphertexOS allows your SecureNAS® to share the data on a USB drive over your local network.

Storage And Sharing


ZFS Filesystem and Volume Manager

OpenZFS for a safer, more resilient system.

Highly flexible storage pool and volume configuration options including storage pools grow/re-layout for ZFS-based pools, thin provisioning/over provisioning for storage volumes, along with volume resizing. Compression can be enabled for storage volumes which both increases usable capacity and performance by reducing the amount of stored data.

Data Optimization

  • Inline Deduplication
  • Incline Compression (LZ4, LZJB, ZLE, GZIP 1.9)
  • Thick, Thin, and Over-Provisioning
  • Lightweight snapshots and clones take up space only after changes are made

High Data Reliability and Availability

Data integrity checks (Bit Rot Protection) are automatically computed for both data blocks and meta-data blocks with the ZFS-based advanced storage pool type.



Customize the IP Address and DNS settings using a unique algorithm that detects only the changed parts of files and MTU for each network interface.


Configure up to three (3) DNS addresses and a DNS search path.


Combine network interfaces to enhance performance by aggregating their bandwidths.


Create routes for individual network interfaces and assign their priority for optimizing routing.


Add custom host entries in order to resolve host names without using a DNS.


Create backup schedules that can be saved to local drives, LTO tape and industry standard cloud services. These backups are available to restore your SecureNAS® in the event this becomes necessary for any reason.

Status And Notification

Status Logs

View both system logs and user logs to monitor the health and activities of your SecureNAS.

Performance Profile

CiphertexOS dashboard gives users an overview of system performance and resources.


Monitor drive health and receive advance warning of potential drive failure to take preventative action.


CiphertexOS employs the LCD front panel of your SecureNAS® to display system and status information.


Access the sensor monitor via the SecureNAS Dashboard to view the current status of its hardware components. Any component in an out-of-range condition will trigger a notification.


Configure CiphertexOS to automatically send event notifications to an email address.
