Network Firewalls

Next-Generation Threat Protection for Every Network

Network firewalls inspect and control traffic at the network perimeter using IDS/IPS, VPN, content filtering, deep packet inspection, and cloud-based threat intelligence. The lineup from SonicWall, Ubiquiti, and ZyXEL covers entry-level appliances for small offices through high-throughput units for enterprise campuses and multi-site deployments, all part of the networking infrastructure catalog.

Network Firewalls for Every Environment

• Branch office security — site-to-site VPN tunnels connecting remote offices to headquarters with full threat inspection at each location
• Remote workforce VPN — SSL VPN and always-on VPN for employees working from home or traveling, with client and clientless access options
• Content filtering for education — web filtering policies that comply with CIPA requirements for K-12 schools, universities, and libraries
• PCI compliance for retail — deep packet inspection and network segmentation for businesses processing credit card transactions
• Multi-site management — centralized firewall policy management across dozens of locations through cloud-based platforms like SonicWall Network Security Manager

Choosing the Right Network Firewall

Start with throughput. Every firewall has a rated throughput for basic packet forwarding and a separate, lower throughput when security services like IPS, antimalware, and SSL decryption are enabled. Size your firewall based on throughput with all security features turned on. A 50-person office with a 500 Mbps internet connection needs a firewall that inspects at least 500 Mbps with full DPI enabled. SonicWall's TZ, NSa, and NSsp series scale from small offices to large enterprises with patented RTDMI threat detection and cloud-based sandboxing. Ubiquiti's UniFi Gateway series includes threat management through the UniFi Controller at no additional per-device cost, integrating with the broader UniFi ecosystem. ZyXEL's USG FLEX line offers bundled security licenses with an accessible web interface.

VPN and Remote Access

Site-to-site VPN connects branch offices securely over the internet, creating a permanent encrypted tunnel between firewall appliances at each location. SSL VPN or remote access VPN lets individual employees connect from home, hotels, or on the road using client software on their laptop or phone. Check the firewall's maximum concurrent VPN tunnel count and VPN throughput to match your remote access needs. SonicWall uses annual subscriptions for gateway antimalware, IPS, content filtering, and sandboxing features. Ubiquiti includes basic threat management at no additional cost, while ZyXEL offers bundled security license packages.
