Secure, Scalable Computing for SD-WAN, uCPE, Network Security and the Intelligent Edge
Portwell network appliances give solution providers, network equipment vendors and service providers a reliable hardware foundation for SD-WAN, uCPE, next-generation firewall, VPN, intrusion detection, content filtering, UTM and other virtualized network functions.
From compact fanless desktop gateways for branch offices to 1U and 2U rackmount systems for the data center, our platforms combine high-density networking, hardware security and long-term availability - with options such as TPM, IPMI and LAN bypass for secure, reliable operation.
built for modern network infrastructure
From Branch Edge to Data Center
Network infrastructure is becoming more distributed, software-defined and performance-intensive. Network appliances need to combine computing performance, high-density connectivity, security, flexibility and long-term availability in a single platform.

network applications
One Platform. Multiple Network Use Cases.
01
Network Access Control (NAC)
Defines and implements network security policies, including how end-node devices are allowed to connect to the network.
02
Firewall
Permits or denies network communication based on pre-defined rules between the public internet and the private enterprise network.
03
Virtual Private Network (VPN)
Creates a virtual tunnel that protects the data and IP address of remote users on the public internet.
04Intrusion Detection /
Intrusion Detection /
Prevention (IDS/IPS)
Identifies, logs and reports possible incidents and blocks detected intrusion attempts.
05
Anti-Spam, Virus, Spyware
Runs on secure web gateways to scan incoming network data and prevent malware threats.
06
Content Filtering
Monitors outbound sensitive data and stops the delivery of restricted content if not authorized.
07
Unified Threat Management (UTM)
An all-in-one appliance combining network security functions - less complex and more cost-effective.
08
Load Balancing
Manages the bandwidth of outbound links between enterprise network and internet based on congestion and current load.
09
Application Delivery Controller (ADC)
Advanced traffic management in the data center that controls traffic flow to servers based on application-specific criteria.

Network Appliance Questions, Answered
What is uCPE?
uCPE stands for universal Customer Premises Equipment: one standard x86 appliance at the customer site that runs several network functions as software — firewall, SD-WAN, routing, WAN optimisation — instead of a separate box per function. The hardware stays the same; what it does is defined by the software on it.
What is the difference between SD-WAN and SD-Branch?
SD-WAN manages the wide-area connections of a site: which link a packet takes, and how the traffic between branch, data centre and cloud is steered. SD-Branch goes one step further and puts the local network of the branch — LAN, Wi-Fi, security — on the same platform.
How do Intel® QAT and DPDK improve network appliance performance?
Both remove work from the general-purpose CPU path. Intel® QuickAssist Technology offloads cryptography and compression to dedicated hardware, which matters for VPN and TLS throughput. DPDK bypasses the kernel network stack and processes packets in user space, which raises packet rates and keeps latency predictable.
What is LAN bypass and why does it matter?
LAN bypass connects two network ports directly in hardware when the appliance loses power or its software fails. The traffic keeps flowing through the device instead of stopping at it — important wherever an inline appliance sits in a path that must not go down with it.
What is the difference between a desktop and rackmount network appliance?
Desktop appliances are compact and fanless and are built for branch offices, edge sites and places without a server room. Rackmount systems are 1U or 2U, offer far more networking and expansion, and are built for enterprise and data-centre deployments — including redundant power supplies.
Can network appliances support 5G?
Yes — through M.2 or mini-PCIe slots for a cellular module and the matching antenna openings. Which platform fits depends on the module, the number of SIM slots and the thermal budget; our engineers can scope that for a given deployment.
Can Portwell customize a network appliance?
Yes. Portwell’s Design & Manufacturing Services cover custom network I/O and expansion cards, mechanical and thermal design, BIOS and firmware including secure boot and pre-loaded images, ODM/OEM branding and integration, certification support, and the step from pilot to volume production.
What applications can Portwell network appliances support?
Network access control, firewall, VPN, intrusion detection and prevention, anti-spam and anti-virus gateways, content filtering, unified threat management, load balancing and application delivery control — on the same hardware family, differentiated by the software that runs on it.
