Firewall SonicWall TZ Series TZ380 — network security appliance with 1 GbE and 2.5 GbE ports

SonicWall TZ Series TZ380 is a compact hardware firewall designed for small offices and branch locations. The appliance combines perimeter security, application-aware inspection and secure remote access capabilities with flexible interface speeds, including 1 GbE and 2.5 GbE ports, to support mixed-speed network environments. Its form factor and throughput characteristics are intended to deliver predictable protection and maintain reliable connectivity for everyday business traffic without requiring a large rack footprint.

Advantages

The TZ380 provides stateful packet inspection and intrusion prevention in a small, energy-efficient chassis, enabling continuous monitoring of incoming and outgoing traffic. Built-in 1 GbE and 2.5 GbE ports allow straightforward integration with modern switches and uplinks while supporting higher-speed segments where needed. The appliance supports VPN and secure remote access for branch users, and its management options include centralized and local configuration to fit a variety of administrative models.

Suitable for

• Small office networks and remote branch sites
• Small businesses requiring mixed 1 GbE and 2.5 GbE connectivity
• Environments needing perimeter protection, intrusion prevention and secure VPN access
• Deployments with limited rack or desktop space

Key specifications

• Network interfaces: combination of 1 GbE and 2.5 GbE Ethernet ports for mixed-speed connectivity
• Security functions: stateful packet inspection, intrusion prevention and application-aware traffic control
• Remote access: VPN support and secure remote connectivity options
• Form factor: compact desktop/rack-capable appliance suitable for small sites
• Management: local and centralized configuration and monitoring capabilities

How to use

Mount the TZ380 in a suitable location with access to wired network segments and power. Connect LAN and WAN links according to your network topology, using 1 GbE ports where standard connectivity is required and 2.5 GbE ports for higher-throughput uplinks or aggregation. Perform initial configuration through the device web interface or a centralized management platform, define firewall policies, enable intrusion prevention and configure VPN settings for remote users. Apply and monitor security services per site policies and routinely check logs and updates to maintain protection levels.

Usage recommendations

For balanced performance, use 2.5 GbE ports for uplinks or aggregation points and 1 GbE ports for access switches. Keep firmware and threat signatures up to date, apply least-privilege firewall rules, and schedule regular configuration backups. Evaluate traffic and throughput after deployment to ensure the appliance nominally meets site requirements; consider central management for multi-site environments to simplify policy consistency.
