SonicWall TZ needs user interface improvements, better threat intelligence, enhanced support, bundled VPN licenses, and stability and performance updates.
You should not look just at a data sheet, but also look at real tests in the field and load tests from companies who are making them.
Founder at a tech services company with 11-50 employees
The API needs better integration to match accounts and objects more effectively.
Senior Network Consultant at Visionet Systems Inc.
Now, these features require separate products like FortiManager, FortiAnalyzer, and a FortiCloud subscription for reporting.
Chief Executive Officer at a tech services company with 1-10 employees
Integration with other vendors, especially with VPNs, can be challenging and requires more effort when configuring.
CTO at Exceed NetSec LLC
What could be improved about SonicWall TZ is the threat intelligence, which by far is not at the level of vendors such as Fortinet, Palo Alto Networks, and Check Point.

SonicWall TZ could benefit from newer technology.
Administration IT at a engineering company with 11-50 employees

I don't have this experience with Fortinet FortiGate-VM because my colleagues in Germany are reaching better prices than me.
Network Administrator at THK Co Ltd
Savings stemmed largely from automating the process using Terraform.
Senior GCP Engineer at a computer software company with 51-200 employees
More licenses are required to purchase the perpetual license for SSL VPN and Global VPN.
Pre Sales at ITCG SOlutions Pvt Ltd
When comparing similar products across vendors, there may be a small difference in cost.

Network Administrator at THK Co Ltd
Faced hardware limitations and setup challenges but have improved network protection over time
I spent much time finding exact firmware on Aruba which was working with these guns, but it is not optimal because it is not the latest version, so there could be potential security problems. We decided to replace those access points with another one. I personally have trouble because I don't know the exact life cycle of Fortinet FortiGate-VM boxes. I don't know if the life of boxes is five years or something else; we moved from our previous company, which sold us to other companies. Before 10 years, we had a special department that took care of core networks, including firewalls. After that, this responsibility fell to me and my colleague. It is not easy to set up these Fortinet FortiGate-VM boxes properly because we didn't have previous experience with this kind of solution. At first, we set up only a few rules that were not secure enough, and over a couple of years, we improved the settings and security of these Fortinet FortiGate-VM boxes. Currently, I have one Fortinet FortiGate-VM that needs to be replaced next year, and this box is not so powerful, so I need to redirect some traffic to another Fortinet FortiGate-VM. It is stable, but because the CPU processor of this box is not powerful, I need to redirect some traffic to another box. In the future, I need to choose a higher-level box to prevent potential troubles with the power of this box.

Web filtering and traffic balancing have improved security for SMBs but threat insight still needs work
I assess the machine learning capabilities of SonicWall TZ in proactive threat detection to not be at the level of other vendors such as Palo Alto Networks, Fortinet, and Check Point. It is somewhere in between, so I would not recommend it for a large enterprise-level organization to rely on because it is not at that level. SonicWall TZ's content filtering service is reliable. We have used it, but it is not very reliable compared to brands such as Fortinet, Palo Alto Networks, or Check Point. What could be improved about SonicWall TZ is the threat intelligence, which by far is not at the level of vendors such as Fortinet, Palo Alto Networks, and Check Point. Their threat intelligence needs to be improved, as does the GUI, which is not as user-friendly compared to devices such as Fortinet. They could learn from their competitors by making the product more user-friendly. The product interface is not that user-friendly. By adopting a more user-friendly GUI, improving threat intelligence, and enhancing the available guides would be beneficial. In my understanding, in some cases, the KB articles and knowledge articles were not that efficient. They were useful, but they could have been more precise with the knowledge base articles. They need to provide more information about SonicWall TZ, specifically more documentation and more troubleshooting articles. Other than the threat intelligence and the user-friendly GUI, there are no other additional features that I can think of for SonicWall TZ in the future or at least in the next release to make it more competitive.
