Senior Cybersecurity Analyst at a tech company with 10,001+ employees
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.

Director at Aquila ICT Solutions
Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management
The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.
