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

"The product is easy to use and is stable. The SV1 functionality is a benefit."

"We are a visual effects company, and there have been a number of high profile security issues in our industry. This has brought us to a higher standard of security, which our clients are very keen on these days."

"It is a good source for firewall protection."

"It is easy to use and performs very well."

"It's very easy to configure."

"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."

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

"I like several features that this product has, such as antivirus and internet navigation inspection. It is also simple to use."

More Fortinet FortiGate pros

"OPNsense is easy to use and open source."

"OPNsense is very stable, easy to upgrade, and maintain."

"We have been operating here in our lab for several months, and everything appears to be extremely stable."

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

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

"The initial setup is easy. It only takes 15-30 minutes to deploy."

"The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."

"OPNsense is highly stable."

More OPNsense pros

"I find the security we are able to do with the policies to be valuable. The monitoring is valuable as well."

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

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

"Its user interface and simplicity are the most favorite parts for our clients. They find it stable and easy to use. Its performance is also good."

"Once it's configured properly, the solution is unbreakable."

"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."

"We use the content filter quite a lot because it's an office setting. During working hours, we like to censor the sites users can visit so it increases productivity. Therefore, the content filter has been good for us."

"The solution is priced fairly and competitively."

More SonicWall TZ pros

Cons

"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."

"The initial setup and configuration are not intuitive and require training."

"I would like to see a more intuitive dashboard."

"They should offer special pricing to premium partners and customers."

"Usually, we sell the bundle with the UTM or threat management piece with IPS, IDS. Other providers, such as Palo Alto, are ahead in terms of safe functionality. So, for me, delivering truly safe service is probably something that still needs to be improved."

"Fortinet FortiGate needs to improve the logging and reporting. Additionally, the next-generation application's policies should be improved. When they were released they had bugs."

"I don't like that anything more than very basic reporting is not included."

"Fortinet FortiGate is a stable solution. However, my issue is the performance only. When I use all the profiles, this affects the performance. From the beginning, I should have had a better sizing of the box."

More Fortinet FortiGate cons

"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."

"While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."

"An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."

"I would like better documentation concerning the provided packages and their integration."

"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."

"You will need additional training before you can actually start to use it."

"On the customer-side, because I'm a small business, I need a cheaper or free solution option."

"The solution could be more secure."

More OPNsense cons

"It needs more robust self-help documentation along with examples and things to watch out for."

"The dashboard needs to be improved."

"The price could be better for us in Bolivia."

"The solution's pricing could be made cheaper."

"Full monitoring obviously needs to be improved. We need full monitoring covered under the security licensing."

"Its reporting can be improved. Currently, we cannot directly get the user names. It only shows the IP, which makes it a bit confusing because we need to use the IP to find the user. If we could directly get the name of the user, it would be better."

"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."

"If the operation increases and the bandwidth consumption increases, it does not perform as per the expectations."

More SonicWall TZ cons

Pricing and Cost Advice

"The pricing for the product is alright."

"Pricing for this product is comparatively lower than other products. It's an affordable solution, but when expanding the number of users, they'll ask you to replace the model, so that's an added cost."

"The initial setup is super straight forward and as far as the licensing goes for the small product that we have, the pricing was pretty competitive. It wasn't as simple and as cheap as a SonicWall but for the service we would get it was a good price."

"It is an inexpensive solution."

"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."

"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."

"We have the full license that included all of the features and support."

"The price is okay."

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."

"The price of OPNsense is good."

"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."

"It is free."

"We are using the paid version."

"OPNsense is open source software so at this time it is free for us to use."

"It's not expensive."

"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."

More OPNsense pricing and cost advice

"Licensing fees are on a monthly basis."

"The licensing scheme of SonicWall TZ is cost-effective. It's an affordable product, but some competitors, e.g. Sophos and Fortinet offer more competitive pricing."

"Licensing costs have been around $2,000. There are no other costs above the standard licensing fees."

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

"It comes to a range between five hundred to seven hundred dollars."

"The pricing was a factor for us, and we felt that the price was good."

"The prices are expensive."

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