Why upgrade to a SonicWall Gen 7 TZ Series firewall

by Paul Heritage


  1. 1. Multi-gigabit support in desktop form factor, fiber interface and high port density
    • Benefit: Organizations that require increased throughput to support bandwidth-intensive applications and data transfer need multi-gigabit ports. Multi-gig firewalls work seamlessly with SonicWave APs and SonicWall Switches to deliver end-to-end multi-gigabit performance. In addition, having greater number of ports allows organizations to connect more devices directly to the firewall.
    • Difference: The TZ470/570/670 series next-generation firewalls are the first desktop form factor to bring multigigabit (2.5/5/10G) interfaces or fiber (SFP+, SFP) interfaces, while the rest support only gigabit interfaces. Gen 7 TZs supports a minimum of 8 ports while Gen 6 supports 5.
  2. 2. Superior hardware upgrades with expandable storage and redundant power supply
    • Benefit: Gen 7 TZs come an expandable storage that enables various features including logging, reporting, caching, firmware backup and more. Secondary power supply is available for redundancy in case of failure, providing business continuity.
    • Difference: TZ570/670 series come with an expandable storage slot on the bottom of the device that provides the ability to expand up to 256GB, while Gen 6 does not. TZ670 comes preloaded with 32GB expandable storage and TZ570/670 series firewalls support two AC power supplies for redundancy. The optional redundant power supply is available for purchase, while other models excluding the TZ570/670 series, support just one power supply.
  3. 3. Groundbreaking firewall inspection, DPI performance and IPSec VPN performance
    • Benefit: With increased network bandwidth requirements from IT trends such as apps, HD video streaming and social media, faster firewall inspection, DPI and IPSec VPN performance provides a secure network without performance degradation. Having a faster firewall performance provides organizations with a greater capacity to utilize higher internet speeds and support more concurrent and remote users.
    • Difference: Gen 7 TZs offer up to 4 times firewall, DPI and IPSec VPN performance over Gen 6 firewalls.
  4. 4. Scale higher with increased connection count (per second, SPI, DPI, DPI-SSL)
    • Benefit: Having a higher number of concurrent connections provides greater scalability by enabling more simultaneous user sessions to be active and tracked by the firewall.
    • Difference: Gen 7 TZs offer up to 15 times maximum connections over Gen 6 firewalls.
  5. 5. More single sign-on (SSO) users
    • Benefit: The single sign-on feature improves employee productivity and reduces IT support costs by enabling users to gain access to connected systems with a single ID and password.
    • Difference: Gen 7 firewalls allows up to 5 times more SSO users than Gen 6 series to benefit from the use of single sign-on.
  6. 6. Increased VPN connectivity
    • Benefit: For organizations with remote and branch locations such as Retail POS businesses, the ability to create a larger number of site-to-site VPN tunnels to connect distributed networks together and securely share data is essential.
    • Difference: Gen 7 offers up to 8 times more site-to-site VPN tunnels than Gen 6 firewalls.
  7. 7. High VLAN interfaces
    • Benefit: VLANs support the logical grouping of network devices, reduce broadcast traffic and allow more control when implementing security policies. It provides logical separation of devices on the same network. High VLAN interfaces signify better segmentation and performance for organizations.
    • Difference: Gen 7 TZ series offers up to 5 times more VLAN interfaces than Gen 6 TZ series.
  8. 8. 802.11ac Wave 2 technology with increase in max number of access points supported
    • Benefit: The latest 802.11ac Wave 2 technology enhances WiFi user experience by supporting MU-MIMO technology. Integrated WiFi option enables organizations to extend their wireless network farther without purchasing additional hardware. Alternatively, high number of APs supported by the firewall provide better scalability of the WiFi network.
    • Difference: Gen 7 TZs with the exception of TZ670, offers integrated 802.11ac Wave 2 support while Gen 6 supports only 802.11ac Wave 1 or 802.11n technologies. Gen 7 TZs support up to 4 times more number of access points over Gen 6 series.
  9. 9. Brand-new SonicOS 7.0 support
    • Benefit: The feature-rich SonicOS 7.0 operating system features modern UI/UX, topology view, enhanced policy, advanced security, networking and management capabilities, along with TLS 1.3 and default support for BGP routing without the need for additional license.
    • Difference: SonicOS 7.0 support is available on Gen 7 series and not available on Gen 6 series. Gen 6 series require an additional expanded license to be purchased to enable BGP support while the Gen 7 include BGP support as default with every firewall purchase. Stateful HA support is available on Gen 7 TZs and not available on Gen 6 TZ series.
  10. 10. 5G USB Modem Support
    • Benefit: USB 3.0 port could be used to plug in a 5G dongle for 5G connectivity. It is also backward compatible with 4G/LTE/3G technologies with the use of corresponding dongles.
    • Difference: 5G technology support is available on Gen 7 TZ series and not available on Gen 6 TZ series.
