SecureNAS® CX-40KHD

Large Encrypted Storage Capacity in a Rugged Enclosure (16TB – 80TB)

Supporting four hot-swappable 3.5” HDDs and two internal 2.5” SSDs for fail-safe OS hosting, the Ciphertex SecureNAS CX-40KHD is a high-capacity, rugged, and reliable enterprise NAS powered by an Intel® Xeon® D (4, 8, or 16 Core) processor. Built-in 8 Intel® AES-NI provides integrated support to enable fast and secure data encryption and decryption for a wide range of cryptographic applications, such as bulk encryption/decryption, authentication, random number generation, and authenticated encryption, providing strong security while also reducing latency. Designed to optimize enterprise IT infrastructure, the SecureNAS CX-40KHD comes with two PCIe slots that support 10GbE to 40GbE network interface cards, M.2 SSDs, as well as graphic cards. Incorporating security and scalability, SecureNAS CX-40KHD is an ideal choice for a complete business-ready storage solution with cross-platform file sharing, comprehensive backup and disaster recovery, iSCSI & virtualization, and many other business applications. For added security, CX-40KHD-X comes with any requested number of FIPS 140-2 Level 3 validated Ciphertex Protect® Encryption Keys (once activated, the device’s volumes are only accessible when the key is inserted).

Ciphertex SecureNAS® is made in the USA and certified by a US military approved Environmental Testing Lab.

PXE Boot Server capability is built into the SecureNAS firmware but is not currently accessible by the end-user.  We can allow that functionality to be accessed through the SecureNAS based on customer  requirements.


2 redundant SSDs for caching and hosting the CX-Linux ZFS OS.


32-128 DDR4 ECC memory detects and corrects single-bit memory errors, demonstrating high reliability for crucial applications.


Incredibly solid and rugged design delivers complete physical security during transport.


Two PCIe slots allow for 5GbE/10GbE/25GbE/40GbE NICs, M.2 SSDs, or graphics cards to increase application performance.


Scalable storage supporting virtual machines, containerized apps, centralized storage, backup, sharing, and disaster recovery.


SecureNAS empowers your business. Sleep well knowing your data is totally safe and secure.
