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.

In my experience, the best feature SonicWall NSv offers is its stateful HA, which functions without any impact, ensuring a zero impact failover. This is an excellent feature in SonicWall NSv, and the management of security services is also very easy, which helps in capturing threats and unknown malware.
The stateful feature helps me on a daily basis, especially in critical environments, as customers do not need to experience any downtime during the failover. If any hardware fails, it can continue to work with zero impact failover.
SonicWall NSv has positively impacted my organization, particularly because we need to configure multiple policies for internet access or NAT and port forwarding. Configuring different policies is required, and we can see multiple options on a single page. After making changes, I have not encountered any issues; everything was working very well.
View full review »Some of the best features about SonicWall NSv include its flexible virtual firewall deployment, allowing for deployment in cloud platforms like Azure and AWS, or virtual infrastructures such as VMware and Hyper-V, all while maintaining the same SonicWall policy model. Additionally, it has strong VPN capabilities that provide reliable site-to-site and remote access virtual private networks with stable tunnel performance, complemented by the Threat Prevention Suite, which integrates IPS, Gateway Antivirus, Anti-Spyware, Application Control, and Content Filtering for real-time inspections.
Another strong point is the policy familiarity due to maintaining the same rule-based structure as SonicWall physical firewalls, avoiding the need to relearn basics. Scalability in the cloud allows me to scale SonicWall NSv by choosing the proper VM size or cloud configuration that fits workload and throughput needs, while it also supports segmentation and multi-tier security with centralized logging that works well with external SIEMs for deeper visibility.
SonicWall NSv has had a positive impact mainly in terms of security consistency and operational efficiency, allowing me to extend the same firewall policy and VPN standard I already use on-premises into the cloud without redesigning everything from scratch. A clear benefit has been secure cloud adoption, enabling me to move application workloads to the cloud while maintaining strict access control and encrypted connectivity with on-premises systems, reducing public exposure of internal services and improving overall security posture. Day-to-day management has become easier because the policy model and VPN handling are familiar, facilitating faster troubleshooting and less risky adjustments. I have already seen stable VPN connectivity and predictable performance, which has decreased connectivity-related incidents.
SonicWall NSv has helped me to secure cloud workloads faster, maintain consistent security controls, and reduce operational overhead without needing a completely new firewall platform.

The best features with SonicWall NSv, based on my experience over several years, include next-generation firewall capabilities including stateful inspection and deep packet inspections. Advanced threat blocking at the perimeters is better than basic L3 and L4 firewalls.
IPS detects and blocks exploit attempts, protects virtualized workloads against known vulnerabilities, and helps reduce lateral movement inside networks.
Gateway antivirus and anti-malware scan traffic in real-time, blocking malware and ransomware before they reach servers or endpoints. It works across HTTP and HTTPS traffic with SSL inspections.
Among all of these features, the one I rely on the most in my day-to-day work is Deep Packet Inspections with IPS in SonicWall NSv. In our environment, most applications and users access services over the internet and cloud platform, so we are constantly exposed to external threats. With DPI and IPS enabled, it inspects traffic in real-time at the application and content level, not just at the port level. It detects and blocks attack exploits, including brute-force attacks and malware before they reach the server. It provides protection even when applications have unpatched or zero-day vulnerabilities.
The customer support for SonicWall NSv is outstanding, and the support from SonicWall is excellent.

The best features SonicWall NSv offers include DPI, which inspects every traffic that comes into the virtual machines, and that is one of the most important features for me. Additionally, it has Advanced Threat Protection, flexibility in applying policies, and VPN and SSL VPN connectivity, which are the major features that I think are very good.
Advanced Threat Protection has made a difference for my environment by providing real-time, memory-deep inspection and a machine learning feature that is able to learn the way these devices behave and analyze them. The cloud delivery threat intelligence spots suspicious behavior in just a few seconds, stopping it before execution, automatically blocking and quarantining files. These features are very important, as well as the machine learning features that evaluate file system changes, help in changing the registry, and prevent network course process behavior. These key advantages are what I have observed in the few years of deployment.
I think the machine learning feature is very important because next-generation firewalls need that feature to help us review the latest trend of attacks, which are becoming more prevalent and smarter. Without the implementation of machine learning, preventing these threats on the network becomes very difficult, so I truly appreciate this feature.
SonicWall NSv has impacted my organization positively as I see a lot of threats being detected and blocked when I review the logs. The infusion of many signatures for the DPI helps me to review all the logs and identify the forms of attacks I am facing on a daily basis, such as more than 500 different brute force attacks trying to guess my admin password to breach the firewall. These logs really assist me in understanding the threats to specific factions of my organization and applying the relevant security policies to secure the entire network.
View full review »SonicWall NSv offers several best features, including security profiles such as IPS protection and malware protection, as well as ease of use. The ease of use with SonicWall NSv is primarily due to the GUI look and feel, which is very user-friendly. This stands out because I work on many firewall products.
SonicWall NSv is more stable and less of a headache compared to Palo Alto because we did not have any issues. I can compare it to other vendors, and when we made some upgrades with another vendor, the policy that was applied was not really there. With another firewall vendor, the logs were not really showing. I did not face these kinds of issues with SonicWall NSv.
There is a feature called Real-Time Deep Memory Inspection in SonicWall NSv, which is basically ATP sandboxing by detecting and blocking zero-day threats. This is a good feature. I would say it is not a unique feature, but one of the best features that is available.

SonicWall NSv offers features that are user-friendly; the options are easily available, and there is no need to drill down into a lot of menu bars to configure it. Support is great as well.
I find the support exceptional, as recently, while building that site-to-site tunnel, the support representative helped us address an issue even when the other party's firewall was not a SonicWall device, demonstrating a good level of expertise. He helped us configure a site-to-site tunnel from a SonicWall device to a non-SonicWall device, so his inputs were very valuable and really saved us a lot of time to configure the tunnel.
SonicWall NSv has positively impacted my organization, as we have not seen any threat or any successful cyberattack; the positive aspect is that we also use SonicWall physical devices for our on-premise infrastructure, so the integration is excellent. Additionally, they have many features in terms of analytics; for example, if we want more information on ongoing threats, they have a tool where we can drill down to each and every packet and see what is incoming and what is outgoing.
View full review »The best feature SonicWall NSv offers is its simple and clean interface that makes it easy to create rules, check logs, and manage security, even in the cloud. The IDS and IPS features work well and block common attacks, scanning attempts, and malicious traffic before it reaches the cloud servers. SonicWall NSv manages very stable VPN connectivity, as seen in the SSL VPN example where remote users can connect securely to cloud resources without issues.
There are many features available, including application control features that can detect and control applications in the traffic. This helps block unnecessary or risky applications. Additionally, SonicWall NSv supports NAT and routing very easily, which is important for hosting applications in the cloud. The most valuable aspect is that it is lightweight and flexible compared to other cloud firewalls, and you can scale the VM size up or down based on your needs.
SonicWall NSv has reduced the risk of attack, which is very impactful for any organization, especially larger organizations. With IPS and threat protections enabled, the risk of attack and malware on cloud workloads is reduced significantly. You can have centralized management where you control everything centrally, giving you one place to manage all cloud security rules, VPNs, IPS, and monitoring. This makes management easier for the IT team. Since it is a virtual firewall, you do not need physical hardware, which reduced costs and removed the hardware maintenance effort. It has improved cloud security, reduced attack risk, allowed secure remote access, saved hardware costs, and made management simple for the IT team.

The best features SonicWall NSv offers include the auto-creation of firewall policies, which is easily useful when we have multiple zones and multiple rules. This feature is one I appreciate greatly. Additionally, the web filter and content filtering policy were amazing, as we had every option to add the subdomains or domains to whitelist, remove from the whitelist, or specifically block any website, and it was working very well. These two are the main features I liked.
When I had to establish multiple new branches and add multiple firewalls at a time for the new openings, the auto-creation of firewall rules saved me so much time on the configuration of firewalls. It was stressful for me to create every rule in every firewall that I was adding into the centralized VPN connectivity, but with this feature, I do not have to spend much time on these multiple firewalls I'm adding.
SonicWall NSv helped our organization maintain and send traffic consistently through our secure VPN channels between the SonicWalls, serving around 300 employees in our organization.

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.
