This appliance is engineered to protect users, data, and applications across on-premises offices and remote locations while simplifying deployment, updates, and ongoing administration.

• The TZ370W delivers robust, multi-layered security powered by SonicWall's next-generation firewall technology. It integrates threat prevention, intrusion detection, malware analysis, and encrypted traffic inspection to help block zero-day exploits and known-bad activity before they reach users or endpoints. This makes it an essential cornerstone for small or distributed organizations seeking enterprise-grade protection without the complexity of a larger security stack.
• With Secure SD-WAN capabilities, the TZ370W optimizes branch connectivity by combining reliable WAN paths with application-aware routing and automated failover. This ensures steady performance for critical business applications, even during link instability. The result is improved user experiences, reduced jitter, and cost-effective access to cloud services, SaaS applications, and data centers.
• The TZ370W includes built-in wireless functionality, enabling a compact, all-in-one deployment solution for small offices or regional offices without the need for separate access points. This integrated capability supports flexible placement, simplified maintenance, and centralized policy enforcement across both wired and wireless clients, while preserving strong security controls over wireless traffic.
• Management and visibility are streamlined through cloud-enabled and on-premises options. The TZ370W works with SonicWall’s Capture Security Center and other management tools to provide centralized policy orchestration, real-time threat intelligence, and actionable analytics. IT teams gain granular control over users, devices, applications, and data flows, along with scalable reporting to meet compliance and governance needs.
• Designed for reliability and ease of deployment, the TZ370W supports effortless firmware updates, secure remote administration, and scalable growth as your network evolves. It is built to operate in diverse environments—branch offices, homerooms, or remote sites—while delivering consistent security posture, predictable performance, and straightforward maintenance for busy IT departments.

How to install SonicWall TZ370W

• Unbox, verify contents, and place the TZ370W in a secure, well-ventilated area with access to power and network connections.
• Connect the WAN/Internet uplink to the appropriate port on the appliance, and connect the LAN port(s) to internal switches or directly to devices as needed. If wireless is used, ensure the integrated wireless radio is enabled in the initial setup.
• Power on the device and access the management interface using the default IP address listed in the product documentation. Use a computer connected to the same network to navigate to this address.
• Run the initial setup wizard to configure basic network settings, including WAN, LAN, DHCP (if needed), and admin credentials. It is recommended to set strong admin authentication and enable automatic firmware updates for ongoing protection.
• Apply the latest firmware and security signatures. Review and enable essential security features such as Threat Prevention, IPS, SSL Inspection, and Content Filtering according to your organization’s policy requirements.
• Configure VPNs (site-to-site and/or remote access) to support secure connectivity for remote workers and branch offices. Create user groups and access policies to enforce least-privilege access for applications and services.
• Set up Secure SD-WAN policies and application-aware routing to optimize traffic flows across multiple WAN links. Define QoS, path selection, and failover behavior to maintain performance for critical applications.
• Implement firewall rules, NAT, and zones to segment the network according to security best practices. Regularly audit and refine policies to minimize exposure while ensuring necessary access for users and devices.
• Enable centralized monitoring and logging via SonicWall’s management console or Capture Security Center. Configure alerts, dashboards, and reports to maintain visibility and speed incident response.
• Test the deployment by simulating normal traffic, evaluating VPN connectivity, verifying threat prevention protections, and confirming wireless coverage if applicable. Validate failover scenarios to ensure resilience in the event of WAN disruption.
