Manager, Information Technology Operation/Presales at TechMonarch
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Secures east-west cloud traffic and improves threat visibility through deep inspection
SonicWall NSv offers great features. I cannot pinpoint a single best feature, but the best feature is the ability to deliver the full, high-efficiency inspection power of a physical SonicWall, including zero-day defense using Real-Time Deep Memory Inspection to the cloud, efficiently removing the performance versus cloud trade-off typically associated with virtual firewalls. Regarding deep memory inspection and real-time zero-day defense in SonicWall NSv, deep memory inspection is distinct from traditional sandboxing methods because it is focused on what is happening in the memory during file execution time, rather than just observing file system behavior. The deep memory inspection process addresses all challenges by employing a proprietary technique within the secure analysis environment, focusing on CPU-level analysis and real-time verdict. Those are the key points. SonicWall NSv's user interface is quite clear and easy to navigate. If someone has not worked with SonicWall and this is their first experience with the platform, I would highly recommend it. It is very easy to navigate and very user-friendly. SonicWall NSv has positively impacted our organization because we gained clear visibility into our network, and it helps to identify potential security issues that we had. We were able to remediate those issues, and so far, we have had a great experience with SonicWall NSv. We were able to manage approximately 99% of network-based attacks through this platform.

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.
