SonicWall TZ270/370/470: Accelerating Digital Transformation for SMBs & Secure SD-Branches


Small businesses and distributed branch offices want to embrace the latest technological developments as much as larger businesses do. But while organizations are working hard to adopt and take advantage of digital transformation, there are several challenges specific to SMBs and branches.

For one, traditional small businesses or branches cannot keep up with today’s continuously evolving cyberattacks. These threats are increasingly targeted and strategized to maximize return on investment, exploiting the ever-increasing attack surface and new attack vectors to become stealthier and more dangerous.

Secondly, the surge of mobile and IoT devices connecting to the network has led to network performance degradation and unpredictable application performance.

Finally, the traditional branch and WAN market is undergoing a massive disruption with the adoption of cloud applications. SD-WAN technology has been a major catalyst in providing the required cloud application performance at significantly lower costs. But adopting multiple point products for security and SD-WAN poses interoperability, deployment, management and visibility challenges that add to the overall cost and time spent to roll out solutions across branches.

An integrated approach is critical for a smooth digital transformation. While there are many products that claim to feature capabilities supporting digital transformation, few offer a complete feature set with high performance at a low total cost of ownership.

Introducing TZ270, TZ370 and TZ470 – integrated SD-Branch platforms with industry-leading performance

In August, we expanded our TZ series with the addition of the TZ570 and TZ670, designed for modern branches. Today, we’re excited to add even more new products to the TZ line of secure SD-Branch appliances. The SonicWall TZ270, TZ370 and TZ470 (and their wireless counterparts, the TZ270W, TZ370W and TZ470W) feature state-of-the-art hardware specially designed to handle the requirements of small businesses and modern software-defined branches.







The groundbreaking performance capabilities of the new TZ series appliances allow automated real-time breach detection and prevention, as well as TLS/SSL decryption and inspection, all over multi-gigabit wired and 802.11ac Wave 2 wireless networks. TZ470 is the first desktop form-factor firewall in its class to include multi-gigabit interfaces. In addition to high port density, high-speed processors and robust onboard memory, the new TZ Series appliances include expandable storage of up to 256GB, perfect for small businesses and secure SD-Branches.

Specifications at a glance:

  • Up to 2.5Gbps of threat prevention performance
  • 10GbE interfaces
  • 11ac Wave 2 wireless
  • Expandable storage up to 256GB
  • USB 3.0 super speed ports for 5G/LTE USB modems

The new TZ appliances are powered by SonicOS 7.0. Launched in August, this completely reimagined operating system provides multiple new features, including support for the new TLS 1.3 encryption standard. More details about the new SonicOS 7.0 can be found here.

Integrated approach for digital transformation

So how do the new TZ270, TZ370 and TZ470 help businesses with digital transformation?

We know that threats are continually evolving. More than simply a replacement for its predecessor, the new TZ series lineup delivers award-winning security solutions with third-party certifications and reviews that meets the need for high-speed threat prevention. Advanced threats such as unknown and zero-day attacks concealed in encrypted web traffic are thwarted using Capture, SonicWall’s cloud-based, multi-engine sandboxing service with patent-pending Real-Time Deep Memory Inspection™ (RTDMI) technology.

With built-in SD-WAN provided at no additional cost, the new TZ series can effectively replace expensive WAN connection technologies and standalone SD-WAN appliances to provide application performance for critical cloud applications through QoS features. Additionally, the use of multi-gigabit interfaces in conjunction with SonicWall Switches and SonicWave access points ensure networks can keep up with the high bandwidth needs rising from the increased mobile devices.

SonicWall Network Security Manager (NSM) offers a centralized management and analytics platform through cloud and on-prem form factors. Small businesses with limited IT staff and lack of cybersecurity skillset can take advantage of the Zero-Touch deployment and unified policy enforcement offered by NSM to save both time and money on deployment. Consolidated security across edge, access and endpoint networks — using TZ series firewalls, SonicWall switches, SonicWave access points and Capture Client endpoint client, all managed through a single pane of glass— amplifies cross-product visibility and control. This end-to-end security stack provides a strong, unified security posture that eases management and offers peace of mind, all at a lower TCO than similar solutions currently on the market.
