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.

Great IPS and DNS filtering with useful tutorials available  
We don't really find a lot of issues on it. If I really have to complain about something, and there's not much, is the free VPN solution is a bit limited. Then again, it is a free solution. That's essentially it. Nothing else on the FortiGate or on the Fortinet OS side is really an issue. That's one of the main reasons why we use them: everything works and works well. For what we use, there isn't really any missing feature. In fact, we actually want to get rid of some of the features that they have due to the fact that, for the security model that we need to implement, having more features actually opens up potential risk. We actually would like to have a device that is more focused specifically on OT environments the operational technologies. We would prefer a device that's stripped down, that doesn't have all the other fluff in the more enterprise system. We actually want a feature where we can remove features that are there that we don't use. That is actually a thing that we find. We use it now in an operational technology environment. We use normal IT equipment. However, it's not a normal IT network. It differs significantly from a normal corporate IT environment. In a normal corporate IT environment, you like the fluff, and the additional features, and you can click, click, click, and you're done. However, all of those features you add to a device open up risk for us. And that is something we do differently in the OT environment in operational technology. We prefer to not have the fluff. We prefer to have only what is needed for the device to do what it needs to do. For example, imagine an additional feature for some sort of additional VPN technology has been added. However, it's not really needed for the OT environment, and it's not configured on the device, yet there's some sort of security threat in there. Now, all of a sudden, somebody can hack your system, and he's in there, and he's switching the lights on and off the entire city. And you don't know about it due to the fact that the additional fluff that we added to the system, we weren't aware of that issue was on there. You can enable and disable certain modules in it. However, with disabling, nobody can really tell us if that module is disabled. Is it really disabled? Is it actually unloaded? Is it uninstalling Word from your laptop, or is it just not running Word?

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

"This is an easy solution to deploy."
"The features that prevent internet connections, the filtering are the most valuable because we did not have any internet protection before."
"The most valuable features of the solution are SD-WAN, filtering testing applications, web filtering, and the new VPN."
"FortiGate firewalls are user-friendly, and I like the security profiling features."
"Reliability is the best feature. We faced some issues when we were setting it up, but the service, portal, and administration are good."
"Virtual Domains (VDOMs) are a feature that we found valuable."
"The most valuable feature is the policy routing and application control."
"It is a safe product."
"Their classification inside of that database of the various threats is typically very, very good."
"It is more robust than SonicWall, particularly on the VPN from site to site."
"The stability of Fortinet FortiOS is great."
"The solution constantly adds features that are useful and user-friendly such as the ability to tweak firewalls through the CLI."
"What I like about this solution, is that it is the only solution that currently offers VPN for clients."
"Fortinet has optimized the WAN environment for connecting users to the application."
"Has a very simple OS and a good price point."
"The most valuable feature of this solution would be the caching feature."
"The most valuable features have been content filtering, and the interface is easy to navigate and to use."
"It is a scalable solution."
"The most valuable feature is the user-friendly navigation."
"The network security is great."
"I find the security we are able to do with the policies to be valuable. The monitoring is valuable as well."
"The features that we have found most valuable in SonicWall TZ are the intrusion and brute force attack prevention."
"The installation is straightforward and took approximately 30 minutes."
"For SMB segments, SonicWall performs well."
 

Cons

"The sniffing packets or packet captures, can be simplified and improved because it's a little confusing."
"The reports are very basic."
"There are SD-WAN network monitoring, SD-WAN features, Industrial Databases, Internet of Things, Detection, etc., however, we do have not licenses for those features. We thought that if you bought a product, you should have all of the features it offers. Why should you need to make so many extra purchases to enable features? They should have one price for the entire offering."
"I would suggest that Fortinet add sandboxing to their solution."
"I would like to see improvements made to the dashboard and UI, as well as to the reporting."
"It could use better throughput on some of the smaller boxes for the branch offices."
"One of the features that I would like to have is to do with endpoint production, it should be integrated. For example, the firewall gets notified of any kind of forensic event that needs to be done, such as if there is a ransomware attack and how it originated, all those records have to be available from the firewall, which is not."
"The solution could be more secure and stable."
"It would be great if they can push the Microsoft updates through Fortinet OS and provide a centralized patch management system. They should also include the data loss prevention (DLP) and data leakage prevention features. They could also add network monitoring more effectively."
"Fortinet could integrate something like a YubiKey for 2FA with their SSL VPN clients."
"The implementation could be simplified."
"FortiOS could provide a more detailed analysis of the network and connected devices."
"There are some issues with the performance. We also had some issues while updating the firmware."
"The reporting and monitoring could improve, they have a lot of limitations. The monitoring is not easy compared to the other firewall."
"They need to integrate more with the SD-WAN."
"Lacks flexibility for different scenario configurations."
"I currently have two of the issues from SonicWall. One issue is that the IP is not the public IP. Sometimes it moves to an alternate source and I have to refresh the new IP then we can go on."
"The small business line has less PPS throughput."
"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."
"The reporting analytics could be improved, it is very unstable."
"The solution's pricing could be made cheaper."
"User interface could be improved."
"In general, the company needs to think contingently and integrate more security options."
"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."
 

Pricing and Cost Advice

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."
"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."
"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."
"They need to be competitive with other solutions."
"The pricing is fair."
"The license is yearly. We pay for the top end. It's called 360."
"Go for long term pricing negotiated at the time of purchase."
"I would rate the pricing a five out of ten"
"The solution could have a better licensing model. It's a bit more expensive than other solutions. The annual subscription is very pricy in Fortinet. The cost could be reduced."
"The support contracts are usually about $100 - $200 a device."
"The software costs roughly half what the hardware costs. Overall, the product is expensive."
"Regarding the cost, the initial purchase is relatively cheap because it comes bundled. However, the subscription renewals can be quite expensive. The renewal costs are high, even though the initial purchase might include discounts."
"The price of Fortinet FortiOS is comparable to other similar solutions on the market. We are on an annual license to use the solution."
"FortiOS is affordable, but its price could be lower."
"We had a three-year license to use Fortinet FortiOS and we are going to renew it this year."
"Pricing depends on implementation and licensing choices and is usually not a practical budget choice for small businesses."
"SonicWall has authorized distributors in our country. They have about two or three distributors in the country, so it makes it a bit easier. What we do is to request a quotation from these distributors, then we do a value for money analysis and see which one of them is giving us a competitive price."
"The price is high compared to some other solutions."
"The license that we purchased is good for three years."
"It is highly priced and has a slow performance compared to other firewalls."
"The price of SonicWall TZ is good for medium-sized companies."
"License renewals come in around $35,000 to $45,000."
"The product pricing is relatively good, compared to other products, including the licenses."
"The price is fair."
