SonicWall TZ370W Network Security/Firewall Appliance

The SonicWall TZ370W redefines desktop NGFW for modern networks, delivering enterprise-grade security in a compact, easy-to-deploy appliance. Built for small to mid-sized organizations and distributed enterprises with SD-WAN capabilities, the TZ370W combines high-speed Ethernet options with robust threat prevention to safeguard users, devices, and data across branch offices and remote locations. With flexible 5 or 10 Gigabit Ethernet interfaces, this device supports diverse network topologies while maintaining simple management, reliable performance, and scalable security as your organization grows.

• 5 or 10 Gigabit Ethernet interfaces provide flexible topology for WAN, LAN, and DMZ segments, allowing you to consolidate security at the network edge while handling high-bandwidth applications, real-time video, VoIP, and cloud services with minimal latency and congestion.
• Next-Generation Firewall with comprehensive threat prevention: deep packet inspection, intrusion prevention, malware protection, content and URL filtering, and TLS/SSL decryption to inspect encrypted traffic. This combination blocks evolving threats at the edge, reduces risk across endpoints, and helps ensure compliant access to cloud resources and applications.
• SD-WAN readiness and versatile VPN capabilities: streamline site-to-site connectivity across multiple branches with automatic failover, policy-based routing, and secure remote access. The TZ370W centralizes security policies for multi-site deployments, delivering consistent protection without sacrificing performance.
• Security services, visibility, and centralized management: built-in dashboards, alerts, and reporting for proactive network monitoring; high-granularity policy control enables precise user- and app-based security. Optional cloud-based management through SonicWall Capture Security Center extends threat intelligence, policy synchronization, and simplified administration across all locations.
• Compact desktop form factor with energy-efficient design and quiet operation: purpose-built for offices, IT closets, and distributed sites, the TZ370W blends powerful security with a small footprint and low noise, making it easy to deploy in environments where space and acoustics matter.

How to Install SonicWall TZ370W

Install and configure your TZ370W quickly with a straightforward setup that minimizes downtime and maximizes protection from day one. The process is designed for IT teams and network administrators who want a secure, repeatable deployment across multiple sites.

• Unbox and place the TZ370W in a secure, well-ventilated area; ensure adequate clearance for cooling and accessible cabling. Connect the power supply and power on the device to begin the initial initialization.
• Plan your topology by designating WAN, LAN, and DMZ ports on the 5 or 10 GE interfaces. Route traffic as required for your network design, and prepare VLANs if segmentation is part of your security strategy.
• Connect a management workstation to the TZ370W and access the device’s management interface via the default setup address. Log in using credentials documented in the user guide and begin the Setup Wizard for first-time configuration.
• Run the initial setup to configure WAN connectivity (DHCP or static IP), assign a LAN address, set DNS, and establish administrator credentials. Apply the latest firmware and license keys for security services to ensure you have up-to-date protection from the start.
• Enable essential security features such as threat prevention, TLS/SSL decryption, and URL filtering based on your organization’s policy. Create basic firewall rules and security zones, then gradually introduce application control and content filtering for refined control over network usage.
• Configure VPN and SD-WAN settings as needed: set up site-to-site IPsec tunnels for branch connectivity and configure remote access VPN for users. Establish auto-failover policies and traffic routing rules to optimize performance across multiple WAN links.
• Validate connectivity by testing Internet access, VPN tunnels, and access to critical resources. Review dashboards and alerts to confirm that protections are active and policies align with your security posture. Schedule firmware updates and license renewals to maintain ongoing protection.
