The Axiomtek NA363R series is a high-performance 1U rackmount network appliance platform designed for next-generation security, VPN, firewall, UTM and bandwidth management applications in SMB, branch office and data centre environments. Powered by Intel Atom C3558 or C3758 processors, it delivers multi-core performance with low power consumption, ideal for deep packet inspection, SSL offload and secure tunnelling. Support for Intel QuickAssist Technology and Intel Data Plane Development Kit accelerates cryptography and packet processing to maximise throughput and minimise latency.

With up to four DDR4 R-DIMM or U-DIMM sockets, the NA363R supports as much as 128 GB of memory for memory-intensive network services, virtual appliances and large routing tables. The standard configuration provides six Gigabit Ethernet ports based on Intel X553 and Marvell controllers, while the C3758 model features an expandable LAN module slot, enabling up to 14 LAN ports for complex multi-segment networks, DMZs and high-availability clusters.

Designed for continuity of service, the platform includes one pair of LAN bypass via latch relay, with options for additional bypass pairs to maintain traffic flow during software or power failures. Onboard TPM 2.0 enhances platform trust and secure key storage, making the NA363R highly suitable for security-sensitive applications such as edge gateways and managed security services.

Front access to console, two USB 2.0 ports and status LEDs simplify deployment and maintenance in crowded racks, as illustrated in the front and rear views on page 1. The compact 1U steel chassis with redundant system fans is optimised for 0 to 45 °C operation and is certified to CE and FCC Class A standards. Running Linux, the NA363R series offers a flexible, robust and scalable foundation for OEM network security solutions and custom software appliances.
