TZ Series Unified Threat Management Firewall

Security and Performance. Hand in Hand.
One of the most secure, sophisticated and widely deployed small business firewall platform on the market today. The TZ Series offers a range Unified Threat Management solutions for small businesses, retail, government, remote sites and branch offices.


Comprehensive Security.

The Dell SonicWALL TZ Series advances UTM protection by combining intrusion prevention, gateway anti-virus, anti-spyware, content/url filtering, enforced client anti-virus, and anti-spam services. Additionally, the Dell SonicWALL application intelligence and control feature in the TZ 215 ensures that bandwidth is available for business-critical applications while throttling or blocking unproductive applications. The TZ 215 also offers advanced application traffic analytics and reporting for deep insight into bandwidth utilization and security threats.


Higher performance protection.

Many consumer-grade solutions lack the processing power and security sophistication to scan traffic for all threats without slowing down the network. Unlike these consumer solutions, the TZ Series utilizes patented Dell SonicWALL Reassembly-Free Deep Packet Inspection® (DPI) technology to examine traffic simultaneously across all ports without introducing latency to the network. As a result, organizations are not required to make a choice between advanced DPI security and network performance. With the TZ Series, they can have both.


Flexible remote access.

The TZ Series includes additional advanced networking features such as IPSec and SSL VPN. The TZ Series is the only available UTM firewall that provides native VPN remote access client for Apple® iOS, Google® Android™, Windows, Mac OS and Linux. This unique client also supports Clean VPN™, which decontaminates threats from VPN traffic. Providing the most secure support for mobile platforms, only Dell SonicWALL delivers full malware scanning of SSL encrypted traffic and application control for Android and iOS devices.


Secure wireless connectivity.

The TZ Series also provides Clean Wireless, combining UTM with high-speed 802.11n wireless to encrypt traffic while also ensuring the integrity of all traffic passing through. In addition, the TZ Series offers an option for 3G2 wireless WAN and analog modem connectivity for use as the primary or failover connection.


Breakthrough simplicity.

Easy to understand and easy to use, The TZ firewall solution is built upon the industry's most advanced object-based management operating system—SonicOS. Thanks to this intuitive interface, you don’t have to sacrifice ease of use for power. Now, distributed enterprises and SMBs can experience enterprise-class high-performance protection at a lower total cost of ownership.


SonicWALL TotalSecure.™

Every TZ Series appliance is also available as a Dell SonicWALL TotalSecure solution, a convenient and affordable solution that combines the hardware and all the services needed for comprehensive network protection from a wide range of network threats - including viruses, spyware, worms, Trojans, keyloggers and more.

TZ 105

The TZ 105 delivers high performance and proven best-in-class protection to small businesses with integrated intrusion prevention, anti-malware and content/URL filtering capabilities.

1 out of 5 eggsSonic wall TZ

Pros: set up was OK

Cons: Now owned by DELL service contract that I paid extra for is worthless waste of money. No clear English spoken. Each month it go's down and after 3hrs and many changes were back up. But every month! Its crazy. I will be looking for another firewall when my extended contract is up. Its typical DELL sales are good service is horrid

Other Thoughts: Look at other options, a company who has true American speaking service techs

5 out of 5 eggsGet this for your Small Business!

Pros: Easy to setup if you have prior experience with general off-the-shelf linksys, netgear, buffalo routers.

This is a major upgrade over those regular routers you find at your local retail store.

This thing protects your organization from a vast number of network threats!

Cons: Easy to configure, but you may need to google some of the not so common features that are available in the firmware.

Only 1 SSL VPN License included, but has them for $40 so not a big deal.

Other Thoughts: Purchase the licenses from, I found them to have much better prices than sonicwall and other websites. We paid $320
for 3yr comprehensive Gateway Security Suite which covers most of the licenses you should be using. We also got the 3yr SonicWALL Enforced Client Anti-Virus & Anti-Spyware for $298 (5-user). That makes this purchase roughly $300/yr including the price of the router if you only use it for 3yrs.

That's a very cheap price to pay to protect your small business network of 5-users or less.

Make sure you configure it properly, if you don't know what you're doing, then hire an IT professional. The firewall is only good if it's configured properly. One wrong open port or weak password and you open the door for hackers.

5 out of 5 eggsEasy to set up

Pros: - Good brand reputation for security
- easy wizards for noobs like me

Cons: no cons that I can see..

Other Thoughts: I'm not an expert in firewalls and networking. The setup wizards worked very well, and made it possible for me to set up this firewall on my fixed IP domain network. I was able to save the important info from my dying Netgear, so I had all the IP's, etc. that I needed to input. I also ran a wizard that allowed me to easily set up ftp access to one of my network servers. It couldn't have been easier! I was very impressed with the firmware and interface, etc.

I was sick of crud Netgear hardware burning out after only months, or a year. I'm hoping this lasts longer. I had a Sonicwall a few years ago that lasted probably 8 years, so I'm hopeful.

5 out of 5 eggsGreat router.

Pros: Great router for small + medium sized businesses.
Highly configurable to handle any scenario.
Very reliable.
Nice add-on features/services for web monitoring/filtering, IDS/IPS, etc.
Multitude of VPN capabilities including smartphone VPN client apps.

Cons: none

Other Thoughts: You get what you pay for, it's worth spending more for business class equipment for use in a business environment over consumer/home equipment.

5 out of 5 eggsGreat SOHO device

Pros: Uses the same quality SonicOS as it's predecessor TZ-100. Reasonably easy to configure as a standard router inside a DSL or Cable internet connection. Extremely configurable outside of the standard information needed. I have one of these configured with multiple LAN's; a business network, and an isolated network for our lab.

I have deployed about 100 of these units (TZ-100/TZ-105) for various clients and purposes, and have only had one issue (see below). I would recommend these for anyone who is tired of replacing those junk consumer units every couple years. I have a couple clients using the TZ-100 on a 35 station network with 20Mbps internet with no issues.

Not a CON because of the quick resolution, but one of these newer TZ-105's for our customer burned up a power pack. SonicWall had the replacement to us the next day, so not going to take away an egg for that. (Uses the same power pack as the TZ-100 series, and out of over 100 units deployed, this was the only one that has failed.)

Cons: SonicWall owned by DELL now, so hard to say long term if the quality will hold up down the road. So far, support hasn't changed much, so kudos there. But Dell scares me with their ongoing quality issues in their business PC area, so I can only hope that they do not change their manufacturing or design processes to be like their PC products.

Other Thoughts: This device, like most other SonicWall devices is highly configurable. Venturing outside the capabilities of the wizards (which help you with basic tasks only) will require more than entry-level knowledge of network protocols, routing, etc. As far as what this device can do, it is comparable to the capabilities of equivalent Cisco devices, but at a much lower price in most cases.

I have been using SonicWall for all of my Small Business installations ever since the quality of the Linksys RV042 went to heck (about 3 years~), and have found them to be quite reliable.
