SonicWall TZ370W Network Security/Firewall Appliance

The SonicWall TZ370W is the latest desktop-form-factor next-generation firewall (NGFW) in the TZ series, engineered for small and mid-sized organizations, distributed enterprises, and branch offices seeking enterprise-grade security without sacrificing performance or ease of deployment. With 10 or 5 Gigabit Ethernet interfaces, integrated wireless capabilities, and a robust security stack, the TZ370W combines high-speed networking with comprehensive threat prevention to protect networks from evolving cyber threats while supporting modern connectivity needs such as SD-WAN and secure remote access. Designed to simplify deployment at the edge, this appliance delivers powerful firewall protection, flexible management, and scalable security services in a compact, desk-friendly form factor that fits neatly into small IT rooms, offices, and retail environments. Whether you’re expanding to multiple sites, implementing a secure guest network, or consolidating security services at the edge, the TZ370W is built to deliver reliable performance and simplified operations for today’s dynamic business networks.

• The TZ370W provides a high-performance, desktop NGFW platform with 10 or 5 Gigabit Ethernet interfaces, enabling you to run multiple high-speed WAN and LAN links, internal segmentation, and secure uplinks to core networks without needing additional hardware. This design supports demanding traffic patterns from modern applications, cloud services, and multimedia workloads while keeping latency low and reliability high. By consolidating routing, firewalling, and security services in a single, compact appliance, you can simplify deployment in SMBs and distributed branch environments while still delivering enterprise-grade protection and policy enforcement.
• Benefit from a comprehensive security stack that combines next-generation firewall capabilities with threat prevention, deep packet inspection, and SSL/TLS decryption to safeguard users, devices, and data. The TZ370W leverages application-aware controls, intrusion prevention systems (IPS), gateway antivirus, anti-malware capabilities, and DPI-SSL to inspect encrypted traffic without compromising performance. Add DNS security, content filtering, and reputation-based controls to block malicious domains and risky sites, helping you meet compliance requirements and protect users across wired and wireless networks. The integrated security suite is designed to minimize risk from advanced threats, targeted attacks, and zero-day exploits while preserving user productivity and network performance.
• SD-WAN and secure remote connectivity are central to modern distributed networks, and the TZ370W embraces this need with flexible WAN routing and reliable VPN capabilities. It supports site-to-site IPsec VPNs and secure SSL VPN solutions for remote workers and partner networks, enabling seamless failover between multiple uplinks and optimized traffic routing based on business policies. With SD-WAN features, you can dynamically steer traffic based on application, jitter, latency, and reliability requirements, ensuring critical applications—such as videoconferencing, cloud apps, and ERP systems—perform consistently even when your WAN conditions fluctuate.
• Integrated wireless capabilities in the TZ370W simplify office deployments by providing secure, high-performance Wi‑Fi at the edge. This enables the creation of robust wireless networks with guest access, strong segmentation, and centralized policy control, all managed through the same security platform as your wired connections. IT teams can extend secure wireless coverage to conference rooms, showrooms, or small retail spaces without adding separate controllers, while maintaining consistent security policies, visibility, and reporting across both wired and wireless segments.
• Manageability, scalability, and future-proofing are baked into the TZ370W’s design. The desktop form factor fits unobtrusively in small spaces, yet the appliance is built to scale with your growing network. Centralized management options—such as SonicWall Global Management System (GMS) and Capture Security Center—provide unified policy enforcement, centralized logging, and comprehensive reporting across sites. Regular firmware updates deliver ongoing protection against emerging threats and new features, while role-based access, detailed activity logs, and secure backup options help administrators maintain control and compliance in busy IT environments.
