Configuration of firewall policies is very easy. I would say its interface gave me the ability to step into firewall and routing. Also I find using the SonicWALL for Site to Site VPN's is extremely easy, in particular, if you want to have VPN fail-over. HA is another good feature. Only because its the most competitive in the market as they give you an HA unit at a reduced cost.

It's simple to deploy which means you can quickly & effectively have a secure network but the reporting tool needs work
What is most valuable?
How has it helped my organization?
Being a simple to deploy product means you can quickly and effectively implement a secure network
What needs improvement?
Since the acquisition of SonicWALL by Dell, I have not seen much in the way of improvements. Probably the key area to improve are as follows
- Better Mail Security (Spam in particular)
- Some improvement in Application Detection and reporting
- Its reporting tool (Viewpoint/GMS) is probably still in need of much improvement.
The death for SonicWall for us unfortunately is the Dell acquisition. You end up competing with Dell for the sale of SonicWALL and then anything else IT related. They don't work with IT partners.
For how long have I used the solution?
I've used SonicWALL NSA for five years.

Learn what your peers think about SonicWall TZ. Get advice and tips from experienced pros sharing their opinions. Updated: April 2025.
849,686 professionals have used our research since 2012.
What was my experience with deployment of the solution?
No issues encountered with deployment.
What do I think about the stability of the solution?
The only stability issues I have encountered is the reporting tools' ViewPoint/GMS. I have seen those virtual appliances fail to the point of needing to rebuild.
The NSA side of things is extremely stable as is the HA functionality.
What do I think about the scalability of the solution?
You need to know the environment to ensure the unit you deploy suits. One negative about the SonicWALLS is the spec sheets for their numbers seem to be quite "optimistic". I used to divide by two to get an idea.
How are customer service and support?
Customer Service:
I haven't dealt with customer support.
Technical Support:Pretty good, they are more than happy to get into the details of any issues and assist in resolving them.
Which solution did I use previously and why did I switch?
This became the de-facto firewall for us.
How was the initial setup?
Initial out of the box setup is very simple as it provides wizards to get you up and running and you can build your firewall on top of those wizards.
What about the implementation team?
When SonicWall was SonicWALL we dealt with a very good vendor team. Since going to Dell it just went downhill.
What was our ROI?
We have seen many cases where installing the SonicWall has helped with security threats or just for safe user browsing
What's my experience with pricing, setup cost, and licensing?
Setup cost is the hardware, configuration and installation. Once its installed, you don't need to refer to it much.
What other advice do I have?
Just map out the connection requirements.

Effective content filtering, interface easy to navigate, and excellent customer support
Pros and Cons
- "The most valuable features have been content filtering, and the interface is easy to navigate and to use."
- "The log sections could be done more clearly."
What is our primary use case?
We use the solution for internet access, content filtering, point-to-point tunnels, and bandwidth management.
What is most valuable?
The most valuable features have been content filtering, and the interface is easy to navigate and to use.
What needs improvement?
The log sections could be done more clearly.
I would like there to be the ability to manage content filtering on a per-user basis or by using the application as we normally would for all users. Currently, it is applied to a group of users and I do not think it is reliable or performing as good as it should.
For how long have I used the solution?
I have been using this solution for approximately 12 years.
What do I think about the stability of the solution?
I have found this solution reliable and stable.
What do I think about the scalability of the solution?
The solution is scalable. Our client's user usage sizes vary. We have clients with five to 200 users using the solution. The number of connections is not limited and there is always room for expansion.
How are customer service and technical support?
The technical support is excellent.
Which solution did I use previously and why did I switch?
We previously used Microsoft before SonicWall. We switched because this solution has more features, such as embedded content filtering.
How was the initial setup?
The initial setup is easy.
What about the implementation team?
If you are not using a vendor or implementation team it can take a maximum of three hours for a medium-size company of 50 users.
What's my experience with pricing, setup cost, and licensing?
The price is fair for the solution for the quality you receive.
What other advice do I have?
I would recommend this solution because it is easy to use and the configuration is simple.
I rate SonicWall TZ an eight out of ten.
Which deployment model are you using for this solution?
On-premises

Easy to set up with good pricing and a variety of security features
Pros and Cons
- "It's a very cost-effective solution."
- "The stability could be a lot better."
What is our primary use case?
We primarily use TZ300 for our branch offices.
What is most valuable?
The price of the solution is great. It's a very cost-effective solution.
There are a lot of security features - including Capture Client, URL filtering, content filtering, application filtering, et cetera, and they are all very useful in terms of protecting our company.
The initial setup is easy.
What needs improvement?
The stability could be a lot better. The SonicOS, which we were using, was not that stable. Sometimes it is not performing as expected as per the policies we have set.
The log, the logging capabilities, are not so good. For example, the logging for traffic logs was not being stored properly. The logging must support some storage space. If there is a storage device or storage mechanism within it we would be able to get the log easier.
For how long have I used the solution?
We've been using the solution over the last 12 months or so. It's been a while.
What do I think about the stability of the solution?
We haven't found the solution to be very stable. t doesn't operate as we expect it to sometimes. We'd like it to be better, performance-wise.
What do I think about the scalability of the solution?
We currently have 20-25 users in our branch offices. We started with 15 users and therefore we scaled up a bit, however, not in a massive sense. At this point, we likely won't scale anymore.
How are customer service and technical support?
We have been in touch with technical support and I would say that they are responding fine. We are happy so far with their attention. Occasionally we deal with stability issues and we find that they respond quickly.
How was the initial setup?
The initial setup was not overly complex or difficult. It's very straightforward. The whole setup is pretty plug-and-play.
What's my experience with pricing, setup cost, and licensing?
The pricing is very reasonable. It's quite cost-effective. We purchase a license that renews yearly.
Which other solutions did I evaluate?
We did previously also look at Sophos.
What other advice do I have?
We are partners and resellers. I'm a consultant.
I'd advise new users that if they are planning to deploy it for their SMB or have up to 100 users, then they should go with the SonicWall firewall.
I'd rate the solution at an eight out of ten overall.
Which deployment model are you using for this solution?
On-premises

Very stable, good support, easy to configure, and useful for content filtering and defining application rules
Pros and Cons
- "Content filtering and application rules are the most valuable features. It is also easy to configure."
- "Its pricing can be better. It is very expensive."
What is our primary use case?
Our clients use it for VPN, firewall, antivirus, and content filtering purposes. We have its latest version.
What is most valuable?
Content filtering and application rules are the most valuable features. It is also easy to configure.
What needs improvement?
Its pricing can be better. It is very expensive.
For how long have I used the solution?
I have been using this solution for around ten years.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
It is scalable. I didn't have any issues with scalability. Our clients are small organizations with 20 to 40 users.
How are customer service and technical support?
Their technical support is very good. I also like its documentation, which is easy to access.
Which solution did I use previously and why did I switch?
Our clients have been using different solutions, such as pfSense, and they migrate to SonicWall TZ because it has more security.
How was the initial setup?
Its initial setup is simple. The duration depends on the number of users and configuration, but it usually takes around 12 hours. We have three or four people for its deployment.
What's my experience with pricing, setup cost, and licensing?
Its price is very high, which makes it difficult to convince the clients to buy this solution.
What other advice do I have?
I would recommend this solution for implementing security. I am satisfied with this solution. It meets our expectations.
I would rate SonicWall TZ a nine out of ten.
Which deployment model are you using for this solution?

Offers good protection and support for my network
Pros and Cons
- "They give good protection to my network and support it."
- "I currently have two of the issues from SonicWall. One issue is that the IP is not the public IP. Sometimes it moves to an alternate source and I have to refresh the new IP then we can go on."
What is most valuable?
Most of the features are valuable. They give good protection to my network and support it. It has a good facility with side to side VPN and everything. I use it in all my offices.
What needs improvement?
I currently have two issues from SonicWall. One issue is that the IP is not the public IP. Sometimes it moves to an alternate source and I have to refresh the new IP then we can proceed.
For how long have I used the solution?
I've been using the solution for the past three years.
What do I think about the stability of the solution?
The solution is stable. I like it. The TZ600 is good. I've had no issues or problems. We have about 100 users at the moment.
What do I think about the scalability of the solution?
It's scalable.
How are customer service and technical support?
Technical support is not good. If we send complaints to the SonicWall support they don't provide good support for us. You can't call them by phone.
How was the initial setup?
It's easy to install. I don't remember exactly how long the deployment took.
What other advice do I have?
My advice would be if you're buying this product, you will have to look up the security design. There are not a lot of firewalls up on the market, but I've found SonicWall to be reliant.
I would rate this solution 9 out of 10. It's good.

CIO at ENGEREDE SOLUÇÕES EM TI
Good central interface and solid security features.
Pros and Cons
- "We like the central interface and we like the security features. Additionally, we use SonicWall with VPN connectivity and we have had no problems with SonicWall all these years."
- "I would like to see a SonicWall integration with the DLP tool, this would be interesting. Data Loss Prevention integration."
What is our primary use case?
The purpose of SonicWall is as a unified threat management appliance. We use SonicWall to protect our customers from cyber threat.
We have SonicWall in customer's on-premises environment and we have SonicWall in cloud data centers.
What is most valuable?
We like the central interface and we like the security features. Additionally, we use SonicWall with VPN connectivity and we have had no problems with SonicWall all these years.
What needs improvement?
In the next release, I would like to see a SonicWall integration with the DLP tool, this would be interesting. Data Loss Prevention integration.
For how long have I used the solution?
I have been using SonicWall TZ for about 10 years.
What do I think about the stability of the solution?
SonicWall TZ is a stable solution.
What do I think about the scalability of the solution?
In terms of scalability, we have to choose the right model according to the customer, their company's size, and according to the internet link capacity. Also according to the quantity of user parameters and the user quantity. The number of users and the link capacity are two parameters to define which SonicWall model is appropriate for that company.
How are customer service and support?
They have a good technical support. I have no problem with them.
How was the initial setup?
It is easy to set up SonicWall. It just depends on the scope of the project.
To set up for initial use takes about two hours. We start with the basic configuration and that is enough to start using SonicWall. After that, we do the more complex and detailed configuration of the security features.
Since we can deploy SonicWall in two hours with the basic configuration, we do a fast start because my users are starting to use the web and receive emails. After that, we do the next steps of the complex config for the more detailed secured configurations.
What other advice do I have?
I would recommend SonicWall to other companies for their security, for the end customer and for security companies, to use as a UTM appliance.
On a scale of one to ten, I would rate SonicWall TZ a nine.

- When evaluating Firewalls, what aspect do you think is the most important to look for?
I like the TZ series for very small office, however I generally recommend and implement the NSA series for my clients. (I am not a reseller, I just sell my time). General rule - buy the next model up on a SonicWall if you want it to be sufficient for at least 3-5 years. I love the NSA3600, probably the best SonicWall model that I have managed over the past 10 years.
