While a majority of SonicWall firewalls offer similar benefits, we’re going to focus on comparing the SonicWall TZ400 vs TZ470. From meeting the needs of different businesses of different sizes to modern features in network and firewall security, SonicWall has you covered.
As you might expect, the SonicWall TZ470 is seen as a clear upgrade compared to the TZ400. On another note, the TZ400 has been discontinued, which means it doesn’t hurt to consider an upgrade.
You can still find licenses available for existing TZ400s, but it’s important to be critical of the differences between these two models. This article will highlight what separates the TZ400 from the 470 to help guide your decision-making on modern firewall solutions.
Comparing SonicWall TZ400 and TZ470
When you stack up the specifications side by side, some of the differences are pretty evident. The TZ400 has been discontinued, but that doesn’t mean its capabilities aren’t still viable in today’s world of network security. Before we get into a detailed side-by-side comparison, some of the surface-level differences between the two firewalls can’t be ignored. For example, many companies would benefit from the higher firewall throughput in the TZ470.
Not to mention, the TZ470 supports more demanding networks that demand a higher number of connections and VPN throughputs. Once again, it isn’t that the TZ400 isn’t worth the time or money; it merely underperforms compared to the TZ470 in several ways.
What is the SonicWall TZ400?
Undoubtedly a flexible firewall security option, the TZ400 was once an optimal choice for many businesses. It still is in certain cases, as plenty of people still use the firewall and its associated licenses. However, its discontinuation will eventually phase out the product, as this event has already made way for newer models, such as the TZ470.
A few notable aspects of the SonicWall TZ400 include:
- Blocks malware and zero-day security threats
- Single-pass DPI architecture
- Best for small to mid-size organizations
- Configuration and management are handled through the cloud
- No expansion slots
- No power over ethernet (oE) support
It may seem like a mild choice for larger businesses, but for those who are just getting started, it was a great entry-level option. Once again, you’ll find plenty of people still using this model, but it doesn’t always match up to more advanced firewall technologies.
What is the SonicWall TZ470?
Also considered an entry-level firewall security option, the TZ470 goes a bit beyond some of the parameters of the TZ4700. It’s powered by SonicWall’s OS7 and comes with a range of helpful security features that are more than suitable for modern-day network security.
A few angles that help the TZ470 stand out include the following:
- 3.5 Gbps firewall throughput
- 2.5 GbE ports
- Higher DPI max connections
- More options with network interfaces
- Better VPN throughput
If you were to read through all of the specifications between the two models, you’d likely have a hard time finding what truly makes them different. Considering the technicalities of the topic, reading a side-by-side comparison of SonicWall TZ400 vs TZ470 can help immensely.
SonicWall TZ400 vs TZ470
It’s important to keep in mind that choosing a firewall that’s right for your business shouldn’t automatically default to the newest and brightest model. Although this is an easy choice to make, it’s more important to compare the details with your network needs. In the table below, you’ll find several firewall parameters between the TZ400 and TZ470 that offer a clear picture of their core differences.
| Specific Feature | SonicWall TZ400 | SonicWall TZ470 |
|---|---|---|
| Interface Ports | 7x1 GbE and 1 USB | 8x1 GbE, 2x2.5 GbE, 2 USB 3.0 and 1 console |
| Firewall Throughput | 1.3 Gbps | 3.5 Gbps |
| Threat Prevention Throughput | 600 Mbps | 1.5 Gbps |
| Max Connection (SPI) | 150,000 | 1,000,000 |
| New Connections Per Second | 6,000 | 12,000 |
The list goes on from here, as the TZ470 comes with higher capabilities in many categories than the TZ400. Both serve the same purpose but offer a varying range of benefits and capabilities that should help guide your decision-making process.
Final Thoughts
Starting at the technicalities of firewall security technology can raddle the brain a bit, but the differences definitely matter. Both models are great entry-level firewalls, but the TZ470 is a first choice for many small to mid-size businesses.
