Executive SummaryUpdated on Apr 6, 2025

SonicWall TZ and OPNsense compete in the network security category, with each offering distinct features appealing to small to medium-sized businesses. OPNsense appears to have a slight advantage due to its cost-effectiveness and ease of use, especially for those seeking an open-source solution.

Features: SonicWall TZ is noted for its straightforward configuration of firewall policies, robust Site-to-Site VPN capabilities with failover support, and high availability. It also offers advanced application control and Intrusion Prevention System (IPS) features. OPNsense is praised for its extensive reporting and visibility, DNS-level filtering, and flexible VPN server integration, coupled with the advantages of being open-source with no licensing fees, making it quite cost-effective.

Room for Improvement:SonicWall TZ needs improvements in malware analysis, virtual UTM models, and enhanced application detection. Users also seek better reporting tools and feature integration. OPNsense requires better integration for specific scenarios, enhanced technical documentation, and improved efficiency in VPN setups and usability.

Ease of Deployment and Customer Service: SonicWall TZ's on-premises deployment is coupled with mixed customer service reviews, ranging from excellent technical support to long wait times. OPNsense's open-source nature may pose initial challenges in deployment due to required technical expertise, though strong community support aids in troubleshooting.

Efficient, user-friendly, and affordable

In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Good interface and firewall capabilities and overall easy to use

The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Robust VPN integration stands out despite needing enhanced vendor compatibility

The integrated VPN functionality is working well with the global VPN client, which is a fast client, though it comes at a cost. SonicWall TZ is functional depending on the service level taken by the user. For SMB segments, SonicWall performs well. Despite lacking certain features, it is still considered a good product. The appliance itself is functional and stable, offering integrated solutions.

Quotes from Members

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

Pros

"Their interface is very easy to use, it is without bugs."

"There are great templates, so you don't have to customize them if you don't want to. You do have the option to custom create some folders and some reports, however, with what is there, you don't really need to go through extra effort, as they already give you a lot of predefined views of reports and so forth."

"Application control and the web filter are the best features of Fortinet FortiGate."

"The SD-WAN is the most valuable feature."

"It's a user-friendly firewall. Most of the tasks are very simple. It's simple to configure and troubleshoot this firewall."

"We are using the FortiGate 100D series. VPN, firewall, anti-malware, OTM, and intrusion prevention are useful features."

"Consolidated our network environment at all locations, but mainly at our datacenter."

"The most valuable feature of Fortinet FortiGate is URL filtering."

More Fortinet FortiGate pros

"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."

"The tool's integration is more like a button press."

"The solution is user-friendly and easy to configure."

"It has firewall and VPN capabilities, which are very valuable features."

"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."

"It has an open license. It works very well, and there is an update every month."

"The most valuable features of OPNsense are the GUI and frequent updates."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

More OPNsense pros

"The technical support is prompt, often resolving issues quickly through remote sessions."

"The site-to-site VPN connections, content filtering, and in our current remote working situation, SSL VPN remote desktop connectivity are the most valuable features."

"For SMB segments, SonicWall performs well."

"The product’s filtering and URL-blocking features are valuable."

"Technical support is good."

"It's been very easy to implement and deploy."

"The installation is straightforward and took approximately 30 minutes."

"The product is easy to deploy."

More SonicWall TZ pros

Cons

"I would like to have logs, monitoring, and reporting for a month without extra fees."

"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."

"It can be a little bit more user-friendly in terms of policy definition and implementation. It seems a little bit complicated, and it could be simplified."

"The support is the main thing that needs to be improved."

"I think there could be more QoS features"

"One area for improvement is the performance on the bandwidth demands for smaller devices, as well as better web filtering."

"Its price could be better."

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."

More Fortinet FortiGate cons

"The interface needs to be simplified. It is not user-friendly."

"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."

"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."

"The ability to set the VPN IP address would be a welcome addition."

"Its interface should be a little bit better."

"The solution could be more secure."

"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."

"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."

More OPNsense cons

"From a support perspective, if we're talking tech support I think Silver Partners, Gold Partners, Platinum, whatever level, should have a different number to call. End users can call tech support over at SonicWall if they've paid for support as part of their AGSS or whatever services they bought. The end-user can call, or we can call, however, I don't want to be calling the same line that an end user's calling. I don't want the same response time. I need a different level of expertise."

"The marketing of SonicWall has to be increased. Currently, when it comes to firewalls, most people go for Cisco and Palo Alto. SonicWall should improve its marketing and branding policies to increase sales. Other than that, it is good."

"The areas we would like to see improvement include more features available similar to the equivalent FortiGate appliance, e.g. SSL encryption and inspection. Two-factor authentication capability would be another additional feature that could be included in the next release."

"Support for SonicWall TZ needs improvement, particularly the time it takes before you're able to speak to a support person, e.g. you have to wait for at least 30 minutes on the phone."

"In terms of what needs to be improved, I would say better load balancing and data filtering."

"We encounter issues while generating new reports."

"SonicWall should incorporate dynamic DNS services to eliminate the need for third-party solutions, particularly for environments using dynamic IP addresses."

"We have been facing issues with reporting."

More SonicWall TZ cons

Pricing and Cost Advice

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

"I give the pricing a nine out of ten."

"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."

"The price depends on the size of the company. From the beginning, you just want to know the internet bandwidths, speed, and the number of users to be able to offer the right product and model. They have a lot of products in FortiGate according to the size of the company, like 200D and 300D."

"At the time we bought them, I was satisfied with their pricing; I don't know how the new pricing will be."

"The price is highly competitive when compared to other brands that offer similar functionality."

"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."

"Fortinet FortiGate is expensive."

More Fortinet FortiGate pricing and cost advice

"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."

"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."

"I would rate the pricing three out of ten."

"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."

"We are using the paid version."

"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."

"OPNsense is an open-source solution and it is free to use."

"We are not paying any licensing fees. OPNsense is completely free for us."

More OPNsense pricing and cost advice

"I give the price an eight out of ten."

"The product pricing is justified for the features provided."

"It has a yearly subscription."

"Its pricing is okay as compared to other solutions."

"It is highly priced and has a slow performance compared to other firewalls."

"Licensing fees are on a monthly basis."

"The solution is moderately priced, where it's neither cheap nor expensive."

"We have to pay yearly. Its licensing can be improved, and they should provide more features, such as AV, email filtering, and so on with the basic subscription."
