Network security gateways support VPN technologies such as OpenVPN and IPSec to create encrypted connections for remote users, branch offices, and site-to-site networks. Built-in firewalls with stateful inspection, denial-of-service prevention, and WAN request blocking help control traffic while the VPN provides secure access to approved network resources.

Consider whether the installation needs a single WAN connection, dual WAN for load balancing or link failover, or a configurable WAN/LAN port for multiple internet connections. For LAN connectivity, choose from Gigabit Ethernet, multi-Gigabit Ethernet, or SFP and RJ45 combination ports based on network throughput, connected devices, and whether the gateway includes an integrated switch or Wi-Fi access point.

A network security gateway typically sits between the internet connection and local network, using WAN and LAN ports to connect switches, access points, and other IP devices while routing traffic and applying firewall or VPN policies. Depending on the model, it may also provide integrated switching, VLAN support, multi-WAN functions, and centralized or cloud-based management for connected network devices.

Choose a single-WAN network security gateway for sites using one internet service provider and requiring core routing, firewall, and VPN functions. Choose a dual-WAN or multi-WAN gateway when a site has multiple internet connections and needs options such as link failover, load balancing, or added bandwidth flexibility.
