UniFi Network Security: Firewalls, Segmentation, and Advanced Protection

UniFi’s Advanced Security Features provide comprehensive protection through tools like Zone-Based Firewalls (ZBF), Access Control Lists (ACLs), Client Isolation, and Intrusion Prevention Systems (IPS). This guide explores how UniFi secures network traffic and enforces segmentation.

VLAN Creation and Assignment

UniFi’s Virtual Local Area Networks (VLANs) provide powerful network segmentation to enhance security, performance, and traffic management. Whether you’re isolating IoT devices, securing guest networks, or enforcing policy-based access, UniFi offers both static and dynamic VLAN assignments for maximum flexibility.

VLANs can be mapped to WiFi SSIDs, wired switch ports, or dynamically assigned based on authentication. For streamlined deployments, VLAN Magic simplifies setup on smaller networks, while advanced VLAN methods like RADIUS and MAC-based assignments enable precise control over user and device segmentation.

Learn how to create and assign VLANs in UniFi.

Network Segmentation Tools

UniFi provides a comprehensive suite of segmentation tools to control how devices communicate across VLANs, switches, and access points. These tools ensure secure network isolation, preventing unauthorized access and enhancing security for IoT devices, guest networks, and internal resources.

  • Zone-Based Firewalls (ZBF) enforce precise inter-VLAN traffic control at the gateway level, enabling advanced security policies across network zones.
  • Network Isolation offers a simple, one-click method to block traffic between VLANs without configuring firewall rules.
  • Access Control Lists (ACLs) provide switch-level segmentation, restricting traffic between VLANs or isolating devices within the same network.
  • Client Device Isolation prevents direct communication between devices on the same WiFi SSID, making it ideal for guest networks and IoT security.
