SonicWall TZ370 SecureUpgradePlus Review: Advanced Sensor Tech and Automation for Smarter Network Defense
Introduction
The SonicWall TZ370 SecureUpgradePlus is the kind of network security appliance that makes sense when a basic wireless router is no longer enough. Designed as an advanced SMB firewall platform, the TZ370 Gen7 combines network security, traffic inspection, SD-WAN capabilities, centralized management options, and automated threat-defense features in a compact appliance. This particular bundle includes a two-year Essential Edition protection service suite, giving businesses a more structured approach to maintaining security rather than treating the firewall as a set-it-and-forget-it device.
What makes the TZ370 especially interesting is the emphasis on intelligent detection and automation. Instead of relying solely on a simple perimeter barrier, a modern firewall needs to observe traffic, identify suspicious behavior, apply policies, and respond consistently. That is where the TZ370’s security architecture becomes useful. Its purpose is not simply to move packets between the internet and the local network; it is built to help administrators understand what is happening and enforce security rules with considerably more control.
For buyers searching for a professional enterprise WiFi router bundle, it is important to understand that the TZ370 itself is primarily a security gateway and firewall rather than a conventional all-in-one wireless access point. That distinction matters. It can serve as the security centerpiece of a business network while compatible wireless access points provide the actual WiFi coverage. In a properly designed environment, that separation can be an advantage because each component can concentrate on what it does best.
The included service subscription also changes the value proposition. Security appliances are most useful when their threat intelligence, filtering, and protection capabilities remain current. A two-year service package gives an organization a defined protection period and makes the appliance better suited to businesses that want predictable security coverage.
Features
Advanced threat detection: The TZ370 is designed around active network security rather than passive routing. Its security functions can inspect traffic and enforce configured policies, helping administrators establish a more controlled boundary between trusted and untrusted networks.
Automation-focused security: Automation is one of the most compelling reasons to choose a dedicated security appliance. Instead of requiring an administrator to manually inspect every connection, automated security mechanisms can evaluate traffic against established rules and threat intelligence. This reduces repetitive work and helps organizations respond consistently.
SD-WAN capability: The TZ370 supports SD-WAN functionality, making it relevant for businesses that use multiple internet connections, distributed offices, cloud applications, or connectivity strategies that need more intelligent path management. Rather than viewing every WAN connection as identical, SD-WAN approaches can help organizations make better use of available links.
Gen7 platform: The TZ370 belongs to SonicWall’s Gen7 firewall family. The platform is designed for modern network environments where security, application visibility, remote connectivity, and centralized administration all matter.
Two-year Essential protection: The SecureUpgradePlus configuration includes two years of Essential Edition protection services. For a business buyer, that is important because the appliance and its associated protection services are part of the purchasing decision rather than an afterthought.
SMB-oriented design: The TZ370 occupies an interesting position between consumer networking equipment and larger enterprise security infrastructure. It is aimed at organizations that need professional security controls without necessarily deploying a large data-center firewall platform.
Policy-based control: A firewall becomes valuable when administrators can define which types of traffic are allowed, restricted, inspected, or routed differently. The TZ370 provides a platform for implementing that kind of structured policy management.

Performance and Intelligent Network Management
Performance should be evaluated differently with a firewall than with a simple consumer router. Raw wireless speed is not the primary reason to buy the TZ370. The real question is how effectively the appliance can maintain network connectivity while security services, traffic policies, inspection, and management functions are operating.
This is where the concept of advanced sensor technology becomes particularly relevant. A modern security gateway continuously has to make sense of network activity. Every connection can represent legitimate business traffic, an unwanted application, an attempted intrusion, or simply something that needs to be treated according to a predefined policy. The more intelligently those events can be classified, the less manual effort administrators need to spend on routine monitoring.
Automation does not eliminate the need for a network administrator, but it can make the administrator more effective. A well-configured firewall can enforce security policies consistently across large numbers of connections. That consistency is important because human operators cannot realistically inspect every packet or connection individually.
The TZ370 is also attractive for organizations with changing connectivity requirements. SD-WAN functionality can be useful when a business operates more than one WAN connection or needs to manage connectivity between locations and cloud services. Intelligent routing policies can help businesses think about network traffic in terms of applications and business priorities instead of simply asking whether a connection is available.
Another practical strength is the separation between security and wireless coverage. A business may want several strategically positioned access points to cover offices, meeting rooms, warehouses, or other areas. By using the TZ370 as the security gateway and dedicated access points for WiFi, the network can be expanded without replacing the central firewall every time wireless requirements change.
That makes the product a strong foundation for a professional network rather than simply a standalone wireless appliance. Businesses can build layers around it: switching, wireless access points, endpoint security, VPN connectivity, segmentation, and cloud services. The firewall becomes the intelligent control point where those different components meet.
For administrators, another benefit is visibility. A network can feel perfectly normal to employees while unusual traffic patterns are developing in the background. Automated security tools are valuable because they can help bring those events to the administrator’s attention without requiring constant manual observation.
Installation and Everyday Use
The TZ370 is best approached as a professional networking component rather than a plug-in consumer router. Before installation, administrators should map the existing network, identify WAN connections, determine the desired LAN and VLAN structure, and decide which security services and policies are appropriate.
That initial planning is worth the effort. A firewall is only as effective as its configuration. Automation can execute policies quickly and consistently, but it needs sensible rules to follow. Businesses should therefore avoid enabling features without understanding their effect on legitimate applications.
Once configured correctly, the advantage becomes more apparent. Instead of repeatedly reacting to the same categories of network events, administrators can establish policies that handle routine situations automatically. This is the real value of automation: it moves network security from constant manual intervention toward repeatable, policy-driven operation.
The two-year Essential service period is also useful from a planning perspective. Businesses can budget for a defined protection window and evaluate renewal requirements before the service period expires. That is preferable to discovering after deployment that an important security subscription has unexpectedly reached its end date.

Who Should Consider the SonicWall TZ370?
The TZ370 makes the most sense for small and medium-sized businesses, branch offices, professional environments, and technically capable users who need more than basic NAT and wireless routing. It is particularly compelling where security policies, threat detection, remote access, multiple WAN connections, and centralized network management are important.
It is less compelling for someone who simply wants inexpensive WiFi for a small home. In that situation, the additional configuration and security-management capabilities may be unnecessary. The TZ370 earns its place when the network itself has become important enough that reliability, visibility, segmentation, and security deserve dedicated infrastructure.
It is also a strong fit for businesses that prefer automation over constant manual monitoring. The more devices, applications, users, and internet connections a network contains, the more valuable consistent automated policy enforcement becomes.
