SonicWall TZ370W Secure Upgrade Plus ESSN 3Y | Wireless Firewall

Keep branch security aligned with the pace of your network. The SonicWall TZ370W secure upgrade plus ESSN 3Y is built for organizations that need to replace firewall hardware while maintaining a clear service horizon. With a 3-year term, it fits refresh plans that are measured in budget cycles, not emergency purchases. Wireless-ac support adds flexibility for sites where wired and wireless traffic both matter, while Gigabit Ethernet keeps the appliance appropriate for modern branch connectivity. That combination makes the TZ370W a strong fit for distributed offices that need dependable perimeter control without overbuying capacity they will not use. This SKU is especially useful when procurement wants a defined upgrade path and a longer support window in a single purchase. It helps reduce the operational risk of running older edge hardware, while giving IT teams a cleaner path to standardize security across smaller sites. For organizations that value continuity, the TZ370W offers a practical balance of connectivity, service term, and deployment simplicity.
