About Us

Sub U Systems believes companies in any industry can benefit from a highly secure, high-performance information security solution in a built-to-spec low-power IP networking appliance.

Enterprise level information security no matter where you do business.



Our VPN employs a cryptographic library that has been validated “secure” under Federal Information Processing Standard (FIPS) 140-2 by the National Institute of Standards and Technology (NIST). Our appliances run on firmware that meets or exceeds National Information Assurance Partnership Network Device and VPN Gateway Protection Profile (NIAP PP) requirements.



We provide your company with enterprise-class security and performance no matter how remote your application. Our ability to secure and transport your data over Ethernet-based, 2G/3G/4G commercial and private cellular technologies, as well as line-of-site Wi-Fi-based technologies is unparalleled in the IP-networking segment of the Internet of Things (IoT).

Low Power


Our devices are small and use minimal amounts of power while offering performance levels typically only found in large, power-hungry rack-mount IP networking equipment.

Our devices offer superior VPN throughput performance and are designed for scalability to grow with the security needs of your business, without the need to replace the entire device.



We offer the most robust level of information security technology available, while being built to withstand use in the harshest of operating environments. Our devices ensure the end-to-end security of your data whether your office is on an offshore oil rig, a natural gas pipeline, light-rail commuter train or anywhere in-between.
