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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The customization of firewall rules provides great value to our customers as it allows them to lock things up in the way that they desire. When it is used for internal access, with a VPN in place for remote workers, the firewalling services provided by Azure, such as the default services that can be turned on, are applied. However, the use of a software-based virtual firewall gives us greater flexibility in introducing security controls for customers who are publishing applications that are publicly accessible from the public cloud. This virtual firewall provides an additional layer of security and more extensive security control options to ensure the protection of our customers' valuable information and assets."
"SonicWall NSv is more stable and less of a headache compared to Palo Alto because we did not have any issues."
"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."
"SonicWall NSV is easy to use, and you can use it to manage the logs easily."
"Out of ten, I would rate the solution at an eight."
"In my experience, the best feature SonicWall NSv offers is its stateful HA, which functions without any impact, ensuring a zero impact failover."
"I would rate the overall product a nine out of ten."
"I have seen a return on investment with SonicWall NSv, as I have saved money by saving time and needing fewer employees due to the ease of use, allowing us to manage our resources better."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
 

Cons

"An area that could be improved is the export and import settings functionality."
"SonicWall NSv can be improved due to the lack of proper documentation, because even though there are a lot of documentation available, there are particular use cases that are not included."
"I would prefer to see improvements in the quality of the OS running on it, particularly if there are some bugs. The improvement needed is about the user interface."
"SonicWall NSv can be improved by maintaining its security with up-to-date patches and ensuring it has the latest updates to secure the device."
"SonicWall NSv's performance is reliable but can be limited by single-stream CPU usage when DPI-SSL is enabled, but in most cases, it is a great experience."
"Currently, we are getting challenges with user-wise reports and other reporting details. At present, they do not provide detailed reports compared to other products."
"The management UI sometimes feels outdated and less intuitive compared to some newer firewall platforms."
"I believe SonicWall NSv is performing well overall, but I think it would be beneficial to have physical versions, such as the hardware of SonicWall NSv, for some environments that may not necessarily need to be connected to the cloud."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
