Integration with other vendors, especially with VPNs, can be challenging and requires more effort when configuring.

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.

Featured Reviews

Fernando Kavindra Fernando - PeerSpot reviewer
Senior Pre-sales and Solutions Engineer - Cyber Security at Enterprise Technology (Pvt) Ltd
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.
Gary-Downey - PeerSpot reviewer
Director of Information Technology at a consultancy with 11-50 employees
Has provided built-in VPN tools and reporting features that streamline remote access and monitoring tasks
We do an outside-sourced threat prevention regarding the Threat Prevention features. I haven't run into areas that could be improved or cons versus pros for Untangle NG Firewall. I haven't done anything too advanced when it comes to the filtering, so I'm not sure what can be improved or added. I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules. These areas could be improved to make it a nine out of 10 or a 10 out of 10 for overall rating.
