It is used as firewalls are normally used and performance has been outstanding. We've been very happy with it.

Provides protection with ease of use and flexibility
Pros and Cons
- "The most valuable feature is the protection available, and then ease of use and flexibility."
- "The market seems to be going to a cloud-supported, new generation of firewall products. I think that's probably going to be important to us, the next time around."
What is our primary use case?
How has it helped my organization?
It has provided the necessary security, that's what it's there for.
What is most valuable?
I really don't know. I'm not really an IT person, per se, but I would say number one is the protection available, and then ease of use and flexibility. Those would be the top three.
What needs improvement?
I'm not an IT guy. What I will say is that the market seems to be going to a cloud-supported, new generation of firewall products. I think that's probably going to be important to us, the next time around.

SonicWall TZ
May 2025

Learn what your peers think about SonicWall TZ. Get advice and tips from experienced pros sharing their opinions. Updated: May 2025.
857,028 professionals have used our research since 2012.
For how long have I used the solution?
Less than one year.
What do I think about the stability of the solution?
It has been, to the best of my knowledge, trouble-free.
How are customer service and support?
We haven't used tech support, at least, not that I'm aware of. We outsourced all of our IT stuff. They may have used it, but I'm not aware of anything.
Which solution did I use previously and why did I switch?
We've used nothing but SonicWall, up until now.
What other advice do I have?
I would say the most important criterion, when selecting a vendor, is probably the technology utilized.
The one we've got now is five years old. The next generation with the cloud-based signature and operation... I know SonicWall has what they call Capture, which is advanced threat protection type stuff. I think that is probably what we're going to be looking at next.
There are certainly a lot of options out there, and there are a lot of good options. I would say, stick with a name brand, whether it's SonicWall, or Check Point, or Palo Alto, or Cisco - any of those. You need to stick with a big name brand that is at the forefront of things.

Enables us to centralize our servers so they can provide applications to different locations and users.
What is most valuable?
The main features are support and security.
How has it helped my organization?
We have several locations, each with a VPN to a central office. SonicWall provides each location with its own security and provides our company with the ability to centralize our servers so they can provide applications to all the locations and users.
What needs improvement?
The SonicWall is somewhat misunderstood due to its being a lot more complicated to use and set up. A simpler interface would help this issue.
For how long have I used the solution?
We have been using this solution for four years.
What do I think about the stability of the solution?
There were no stability issues.
How are customer service and technical support?
I would give technical support and rating of 8/10. Most of the time support is with foreign staff and can be hard to understand.
Which solution did I use previously and why did I switch?
We have not used a different solution since I have been with the company.
How was the initial setup?
The initial setup was somewhat complex. The interface can be a little hard to get used to and understand.
What's my experience with pricing, setup cost, and licensing?
It is not cheap, but it is probably one of the best secure firewalls. You get what you pay for!
What other advice do I have?
Shop around and make sure you need this level of security. Have lots of time to get to know this device because the rewards are plenty.

Review about Dell SonicWALL TZ
What is most valuable?
Easy to use GUI
VPN (Site-to-Site and Client-to-Site)
Gateway Security
Built in A/V options
Content Filtering
How has it helped my organization?
The site-to-site VPN allows for consistent communication between sites.
Upgrading the OS is easy and they alert you when an upgrade is available.
Content filtering and gateway security has help reduce visiting unwanted websites and attacks.
Logging helps track down issues bandwidth hogs.
What needs improvement?
I would love to see a more detailed logs and filtering.
Wireless versions have week signal strength in comparison to other wireless routers.
For how long have I used the solution?
5 years
What do I think about the stability of the solution?
Absolutely no issues with stability. I try to reboot them every 6 months to a year for good measure, but not because I have to.
What do I think about the scalability of the solution?
Most of the TZ series are for small to mid size office. I would not recommend these for large to enterprise solutions. I do use one currently for a small community school of 250 students with no issues.
How are customer service and technical support?
Customer Service:
I have not worked with their customer service.
Technical Support:Excellent customer service. Very knowledgeable.
Which solution did I use previously and why did I switch?
This has been a great solution and have never bothered trying anything else. I do have a few Cisco ASA installs, however the cost is a bit higher and more complex to implement.
How was the initial setup?
Setup is quite straight forward. There are some deeper more complex setups that can be implemented. These more complex setups can be achieved through their support or a quick google search.
What about the implementation team?
I personally implemented the solution.
What was our ROI?
I like to think that the TZ series has the best bang for the buck. Full of features and options that you need to control security with out breaking the bank. Perfect solution for smaller businesses.
What's my experience with pricing, setup cost, and licensing?
Sonic Wall has an a la carte pricing model. There are many features and options that you may not need or want and therefore no need to pay for them
The only problem with this model is that it does now use a yearly subscription model. Although the router itself may be less expensive than other competitors, you may spend more in subscriptions.
Product support will require a yearly maintenance.
Which other solutions did I evaluate?
I only work with SonicWALL TZ and Cisco ASA.
What other advice do I have?
Sonic Wall OS is very easy to use but still has all the options and features you need to implement your security.

Easy to configure.
What is most valuable?
Easy to configure. Good for any organization.
How has it helped my organization?
Always saves time for any implementation. IT guys never have lots of time for R&D in some live box.
What needs improvement?
Content filtering, Load balancing. Bandwidth management.
For how long have I used the solution?
5 years.
What was my experience with deployment of the solution?
Never.
What do I think about the stability of the solution?
Once.
What do I think about the scalability of the solution?
No issues.
How are customer service and technical support?
Customer Service:
7/10
Technical Support:9/10
Which solution did I use previously and why did I switch?
Technical support and it wasn't fit for our organization.
How was the initial setup?
Never, it's so easy.
Which other solutions did I evaluate?

The devices are not as good as others, but the price and business model are attractive.
What is most valuable?
The MSSP partnership program is valuable, but is still too expensive. The devices are not as good as others, but the price and business model are attractive.
How has it helped my organization?
We were focused on traditional service provider model, so if one customer ask us to implement an NGFW, we look for the best solution for the client within the market. After getting in contact with Dell Spain, they proposed us to become MSP partner, so we consider to improve our business model to MSSP model.
What needs improvement?
Support is not as good as should be. An NGFW is supposed to use all the functions, so they must be considered as a must. If you switch on all of them, the system is working under the spected figures...
For how long have I used the solution?
I have done a benchmark for around two months. The 500 is still working after benchmarking. We were looking for a solution for a law firm to be able to communicate in a safer mode.
What was my experience with deployment of the solution?
The figures are not valid when you active all the functionalities. So, an office with only 15 workstations is not able to work with a TZ500, which is supposed to be for up to 40 workstations.
What do I think about the stability of the solution?
They are stable if you are not very demanding, if so, they become unstable.
What do I think about the scalability of the solution?
I don't think they are designed to scale, but I haven't tested it.
How are customer service and technical support?
Customer Service:
6/10 - they are not providing the same support level as before.
Technical Support:I haven't used it, but they have contacted me several times to offer their help.
Which solution did I use previously and why did I switch?
I was looking for the best solution for my customer and I found a better one after implementing SonicWALL. I have been a user, administrator and certified architect of Cisco, Checkpoint, StoneSoft, Fortinet, Sophos, Juniper, and most of them are focused for massive environments, not for SMEs.
How was the initial setup?
It was straightforward, but I had to make a few changes to adapt it. However, every installation is different so, you need to adapt.
What about the implementation team?
It was an in-house implementation.
Which other solutions did I evaluate?
I didn't choose this product.
What other advice do I have?
Consider Sophos solution or maybe Fortinet if you don't need the Sophos extra features.
Disclosure: My company has a business relationship with this vendor other than being a customer: R3CyberSecurity.com is a Dell partner, but we have several partnership agreements with different vendors, so we are independent Managed Security Service Providers.

Its easier to deploy and configure than other options, but the GUI configurations and menus are not intuitive.
What is most valuable?
The affordability.
How has it helped my organization?
It's provided security and a VPN connection.
What needs improvement?
GUI configurations and menus are not intuitive, thus making it difficult to identify dependent configurations completion.
For how long have I used the solution?
I've used it for two years.
What was my experience with deployment of the solution?
In most cases no issues, except a few times when the External Interface would not take a public dynamic IP address.
What do I think about the stability of the solution?
There were some issues, when the firewall would work for six months straight, and then cause VPN slowness, which was resolved right after a reboot. Not many companies allow themselves to have such downtime.
What do I think about the scalability of the solution?
No issues encountered.
How are customer service and technical support?
Customer Service:
Service is great.
Technical Support:Service is great.
Which solution did I use previously and why did I switch?
We previously used a mix of WatchGuard and Cisco firewalls. We switched because Dell offered an affordable, stable, flexible option that is easier to deploy and configure.

How has it helped my organization?
We sell the product, and we have a lot of business for it, and our customers are happy with the solution.

It normally comes within eight months for us.

You will be easily impressed with the performance and features available but they doesn't offer virtual UTM models.
What is most valuable?
- The management GUI is easy to configure, friendly to use, manage, and troubleshoot
- IPSec/SSL VPN is easy to configure
- It offers granular level of control for IPS and firewalls with advanced application control features
- You have one console to manage different aspect of the product
- It provides a high level of security
- It is easy to integrate into an existing network
- It provides a high level of throughput
What needs improvement?
- The DPI SSL Inspection needs a lot of improvements
- Dell SonicWALL doesn’t offer virtual UTM models which is a very fast growing area in the world
For how long have I used the solution?
I've used it for three years.
What was my experience with deployment of the solution?
No issues encountered.
What do I think about the stability of the solution?
The firewall does crash and/or unexpectedly reboots.
What do I think about the scalability of the solution?
Generally speaking no, but sizing correctly is main challenge, and that is why you need to make sure you select the right model.
How are customer service and technical support?
Customer Service:
The hold time is very long, and they need to hire more people to handle the huge number of incoming calls.
Technical Support:Dell SonicWALL tech support is excellent, and they meet the evolving needs of their clients.
Which solution did I use previously and why did I switch?
I had a chance to work with Fortinet and Netasq. and am also currently exploring CheckPoint. It was a part of my job when I joined different companies, and each with had partnership with these products.
How was the initial setup?
Most of the deployments were straightforward, whether as a standalone unit or as part of an HA setup.
What about the implementation team?
It was an in-house team who consulted with the vendor for complex installations.
What was our ROI?
It delivers an immediate ROI with a low cost of managing and maintaining multiple security solutions, it increases productivity, and improves security.
Which other solutions did I evaluate?
No other options were evaluated.
What other advice do I have?
Dell SonicWALL UTM is strong in the UTM space with great support. They continue to innovate and deliver a solid UTM product with high throughput speed. Added to this, Dell partners are pleased with their SonicWALL partnership as well as the products features and excellent support.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
I know Dell SonicWall very well since I used to work there for 3 yrs. Many customers now implementing multi-layer approach where they have SonicWall in Route / NAT mode and and IPS/IDS from another vendor such as Fortinet in Transparent mode for better security and visibility. Keep in mind that the IPS/IDS/AV in SonicWall in only signature-based with no Heuristic scanning and no sandboxing .

As an update on this topic - there are new versions of SonicOS planned for the middle of this year which are reportedly going to increase the throughput ratings by as much as 50%. The new features essentially unlock the horsepower that the gen6 platform promised through more efficient code, etc.
