SonicWall TZ370 Network Security/Firewall Appliance

The SonicWall TZ370 Network Security/Firewall Appliance is engineered to deliver enterprise-grade protection for small and mid-sized businesses and distributed networks. As a next-generation firewall (NGFW), it blends advanced threat prevention with streamlined management, giving organizations a robust shield against malware, exploits, and multi-vector attacks while preserving user productivity. Designed for easy deployment in a variety of environments—from single-office setups to multi-site branches—the TZ370 integrates core security services, VPN capabilities, and secure SD-WAN features into a compact, reliable device that scales with your network. With comprehensive protections and a focus on performance, this appliance helps IT teams reduce risk, accelerate threat detection, and maintain secure access for remote workers and on-site users alike.

• Comprehensive NGFW protection with advanced threat prevention. The TZ370 harnesses deep packet inspection, up-to-date threat intelligence, and multi-layer security to block known and emerging threats before they can impact endpoints or data. This includes intrusion prevention, gateway antivirus, anti-spyware, and ongoing reputation-based filtering that adapts to evolving attack techniques, helping you stay ahead in a rapidly changing threat landscape.
• High-performance hardware designed for SMBs and distributed enterprises. Built to handle diverse traffic—from video conferences to cloud-based apps—the TZ370 delivers reliable throughput and low latency. Its optimized security pipeline ensures real-time traffic remains responsive while security services run in parallel, reducing bottlenecks for critical business applications and ensuring a smooth user experience across locations.
• Flexible connectivity and secure SD-WAN for resilient branch networking. The TZ370 supports secure SD-WAN capabilities, enabling intelligent routing, autonomous failover, and bandwidth optimization across multiple links. This means branches can maintain reliable connectivity even when one provider experiences interruption, preserving productivity and reducing downtime for cloud workloads, SaaS applications, and centralized services.
• Robust VPN options for remote work and site-to-site connectivity. With IPsec and SSL VPN support, the TZ370 makes secure remote access straightforward for employees working from home or in the field, while site-to-site VPN capabilities simplify connecting multiple offices. Centralized policy control and user authentication streamline management and improve security posture for distributed teams.
• Comprehensive security toolkit with policy-driven visibility. Beyond core firewalling, the TZ370 includes application control, content filtering, and TLS/SSL inspection to scrutinize encrypted traffic. These capabilities provide granular visibility into application usage, enforce acceptable-use policies, and prevent data leakage while maintaining performance through optimized inspection strategies.

how to install SonicWall TZ370

Installing the SonicWall TZ370 is designed to be straightforward for IT teams of all sizes. With clear step-by-step guidance and an intuitive setup process, you can bring your network protection online quickly while preserving existing services. Before you begin, plan your network addressing, identify the primary WAN link(s), and determine how you want to segment your LAN and any DMZ resources. The following installation workflow outlines a typical deployment that aligns with best practices for SMBs and distributed enterprises:

• Unbox the TZ370 and place it in a secure, well-ventilated location with easy access to power and network cabling. Ensure the device is protected from dust and is vertically organized to minimize heat buildup during operation.
• Connect the WAN interface to your Internet service provider and connect a trusted management workstation to one of the LAN ports for initial configuration and ongoing administration.
• Power on the device and access the management interface using the default IP address or the provided setup media. Follow the on-screen setup wizard to configure initial network settings, administrator credentials, date/time, and basic security posture.
• Enable core security services and features you plan to use: Intrusion Prevention System (IPS), Gateway Antivirus, TLS/SSL inspection (with appropriate policy to balance performance and security), Content and URL Filtering, and Application Control. Create security policies aligned with your organization's risk tolerance, regulatory requirements, and user expectations.
• Configure VPNs for remote workers and branch sites, including IPsec and SSL VPN profiles. Establish access policies, user authentication, and group-based rules to ensure seamless yet secure remote connectivity.
• Set up Secure SD-WAN policies if you have multiple Internet connections or branch offices. Define routing preferences, failover thresholds, and QoS rules to optimize performance for critical applications and cloud services.
• Update firmware and threat intelligence databases from the Capture Security Center or Global Management System (GMS) to ensure you are protected against the latest threats. Regularly monitor logs, dashboards, and alerts to maintain ongoing visibility into security posture.
• Test the deployment by simulating typical user traffic, verifying VPN connections from remote devices, and confirming that security policies are enforcement correctly. Validate that critical business applications perform as expected and adjust rules as needed for optimal balance between security and productivity.
