10 Reasons to Upgrade to the Latest SonicWall TZ Firewall
Some people prefer not to upgrade their products till the bitter end. In some cases, this is fine — you may be able to live with the fact that the laptop you got for college graduation a decade ago won’t run “Hitman 2” or “Metro Exodus,” as long as it’ll connect to the internet and give you a place to store all your MP3s.
But the risks of running an aging firewall extend far beyond fear of missing out: Firewalls must be updated regularly to stop advanced cyberattacks, as well as keep up with the speed, performance and productivity needs demanded by today’s workplace. Here are the top ten reasons why you should consider updating your legacy firewall to the latest SonicWall TZ Series next-generation firewall:
Stop the Most Advanced Threats
Advanced cyber threats are on the rise and affect all businesses and organizations. The cloud-based, multi-engine SonicWall Capture Advanced Threat Protection (ATP) sandbox service provides high security effectiveness against advanced persistent threats and new attacks, including ‘never-before-seen’ ransomware, malware and side-channel attacks. Capture ATP subscribers discover and stop over 1,000 new attacks each business day.
Why upgrade: SonicWall Capture ATP is only available for SOHO 250, TZ350, TZ400 and above firewalls, as well as the NSa and NSsp line. This service is not available for legacy firewalls, including TZ105, TZ205 and TZ215 firewalls.
Inspect More Encrypted Traffic without Slowing Performance
Never be forced to choose between performance and security. With the increased network bandwidth requirements from today’s SaaS apps, video streaming and social media, firewalls with faster deep packet inspection (DPI) offer better network security without performance degradation.
During the first half of 2020, 1 in 12 SonicWall customers with DPI-SSL activated saw malware on encrypted traffic. And the numbers are on the rise: In June, SonicWall recorded 378,736 of these attacks—more than at any other point in 2020 or the last half of 2019.
Simply put, faster DPI performance provides organizations with a greater capacity to utilize higher internet speeds and support more concurrent users — all without sacrificing security.
Why upgrade: SonicWall TZ350 and TZ400 firewalls offer significantly faster DPI performance than the TZ 105 (up to 24x), TZ 205 (up to 15x) and TZ 215 (up to 10x).
Inspect Encrypted Traffic without Increasing Costs
The vast majority of web traffic is now encrypted. And without the proper security controls in place, traffic encrypted by TLS/SSL standards provides cybercriminals a backdoor to your network.
That’s why deep packet inspection of encrypted traffic (DPI for TLS/SSL) is mandatory for businesses of all sizes. Unfortunately, some firewall vendors upcharge you for proper TLS/SSL inspection capabilities (or don’t offer it at all).
Why upgrade: SonicWall TZ350 and TZ400 firewalls include the DPI-SSL license (by default) to inspect encrypted traffic at no additional cost, thereby reducing capital expense. Unfortunately, the TZ105, TZ205 and TZ215 do not support inspection of encrypted traffic.

Secure Growing Remote Workforce
With today’s remote workforce far larger than ever before, companies need the ability to provide employees with secure access to data — anytime and anywhere. A larger number of secure VPN connections is essential to support the increasing number of remote users. But based on the firewall(s) you have deployed, you may have a limit on how many remote employees you can protect at a single time.
Why upgrade: The latest SonicWall TZ400 firewall supports 10 times the number of SSL-VPN clients as the TZ 205 and TZ 215 (100 vs. 10). The TZ350 firewall enables 7.5 times as many SSL-VPN clients as the TZ 205 and TZ 215 (75 vs. 10). The latest SonicWall TZ400 firewall supports 10 times the number of SSL-VPN clients as the TZ 205 and TZ 215 (100 vs. 10). The TZ350 firewall enables 7.5 times as many SSL-VPN clients as the TZ 205 and TZ 215 (75 vs. 10).
Support Faster Wi-Fi Speeds
The world is wireless. Wi-Fi speeds — and users’ appetite for connectivity — are increasing exponentially. The 802.11ac wireless standard delivers the performance, range and reliability of high-speed wireless technology for an enhanced user experience. But in a properly secured environment, they must be paired with a firewall that can support 802.11ac wireless standards.
Why upgrade: The SonicWall TZ350 and TZ400 firewalls support the 802.11ac wireless standard as well as SonicWave 802.11ac Wave 2 access points for high-speed wireless networking. Unfortunately, the legacy TZ105, TZ205 and TZ215 firewalls only support the slower legacy 802.11n wireless standard, and do not work with the latest SonicWave wireless access points.
Reduce Support Costs
Single sign-on (SSO) technology helps improves employee productivity and reduce IT support costs by enabling users to safely gain access to connected systems with a single ID and password. Simply, the more users can access with a single ID, the fewer support calls, IT tickets and complaints will be generated. This equals real savings to your organization.
Why upgrade:
The SonicWall TZ350 and TZ400 firewalls enable twice the population of users (500 vs. 250) to benefit from the use of single sign-on.
Protect More Concurrent Users
There should rarely be a limit on how many users you are able to protect. A higher number of concurrent connections provides greater scalability by enabling more simultaneous user sessions to be active and protected by the firewall.
Why upgrade: The newest SonicWall TZ350 and TZ400 firewalls enable a much larger number of concurrent connections per second, plus deep packet inspection of TLS/SSL-encrypted connections, compared to the TZ105, TZ205 and TZ215.
Increase Speed to Keep Pace with Threat Processing
Modern cybersecurity requires firewalls that can manage network traffic more quickly to deliver the high performance needed for modern-day threat processing. Legacy firewalls can’t process as much traffic volume, sometimes hindering performance and efficiency. This can result in businesses being unable to achieve their promised internet speeds.
Why upgrade: The SonicWall TZ400 firewall, for example, has double the number of security processors as the TZ205 and TZ215 (4 vs. 2). In addition, TZ350 and TZ400 have higher speed processors (1.2 GHz and 800 MHz, respectively), compared with 400/500 MHz processors in the previous TZ205 and TZ215 firewalls. These speed boosts keep your business humming and safe from modern threats.
Boost Memory for Added Users, Logs & Policies
The number of users who require security on your network grows by the day. Unfortunately, the on-board memory of legacy firewalls can only support a finite footprint of users on the network. Advanced firewalls offer more onboard memory to allow for more rules and policies, users, and log messages to be stored on the firewall, making reporting easily accessible.
Why upgrade: The SonicWall TZ350 and TZ400 firewalls have up to four times the onboard memory of the TZ205 and TZ215 (1 GB vs. 256 MB/512 MB). This increased capacity empowers organizations to use a single TZ firewall to protect a larger userbase with deeper and more robust rules and policies.
Boost Performance, Security with Additional VLANs
Creating a greater number of virtual local area networks (VLAN) enables organizations to segment users and devices into additional groups, improving performance and security while reducing hardware costs. The ability to scale these VLANs depends on a number of factors, most notably how many may be protected by a firewall.
Why upgrade: The SonicWall TZ400 firewall provides the ability to create up to five times the number of VLANs as the TZ 205 and TZ 215 (50 vs. 10/20). The TZ350 firewall enables the creation of 2.5 times more VLANs than the TZ 205 (25 vs. 10).
