Manager, Information Technology Operation/Presales at TechMonarch

A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Web filtering and traffic balancing have improved security for SMBs but threat insight still needs work

I assess the machine learning capabilities of SonicWall TZ in proactive threat detection to not be at the level of other vendors such as Palo Alto Networks, Fortinet, and Check Point. It is somewhere in between, so I would not recommend it for a large enterprise-level organization to rely on because it is not at that level. SonicWall TZ's content filtering service is reliable. We have used it, but it is not very reliable compared to brands such as Fortinet, Palo Alto Networks, or Check Point. What could be improved about SonicWall TZ is the threat intelligence, which by far is not at the level of vendors such as Fortinet, Palo Alto Networks, and Check Point. Their threat intelligence needs to be improved, as does the GUI, which is not as user-friendly compared to devices such as Fortinet. They could learn from their competitors by making the product more user-friendly. The product interface is not that user-friendly. By adopting a more user-friendly GUI, improving threat intelligence, and enhancing the available guides would be beneficial. In my understanding, in some cases, the KB articles and knowledge articles were not that efficient. They were useful, but they could have been more precise with the knowledge base articles. They need to provide more information about SonicWall TZ, specifically more documentation and more troubleshooting articles. Other than the threat intelligence and the user-friendly GUI, there are no other additional features that I can think of for SonicWall TZ in the future or at least in the next release to make it more competitive.

User has benefited from stable performance and effective completion of security tasks

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

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

Pros

"I would rate FortiGate Next Generation Firewall (NGFW) as a solution a 10 out of 10."

"The most valuable features of Fortinet FortiGate IPS are firewall and filtering."

"I like its ability to prevent external intrusion into our database."

"The license management is very valuable. You can get a new license each year, or you can enroll every two to four years. You can get the logs, and you will get the information on the risk in your network and the entire organization. With this information, you can take action on your actives, computers, or devices. You can bring your own device as an SSE."

"The initial setup of Fortinet FortiGate was straightforward."

"SSL VPN, Site to Site VPN, UTM features and web override are nice features."

"The wireless control is helpful."

"Fortinet is the best choice for small enterprises because it provides security as per their requirement and comes under their budget, making the pricing very acceptable for medium-level and small-level enterprise customers."

More Fortinet FortiGate pros

"Good site categorization and application controls."

"The solution is very simple and works great and is working fine in the regions that are here."

"With the main firewall routing there, we can do connectivity point-to-point. On the low bandwidth we can connect in all the branches with my corporate office."

"The most valuable feature of this solution is that it is easy to install and maintain."

"We sell the product, and we have a lot of business for it, and our customers are happy with the solution."

"It does exactly what it says on the tin. It is good for protecting the business from being compromised. Its port protection is very good."

"The general feature is the antivirus policy, followed by the ransomware protection, and these are the features I was looking at."

"I usually recommend SonicWall TZ for organizations that are looking for a solution without a big budget because it is quite budget-friendly and easy to deploy."

More SonicWall TZ pros

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

"This is a capable appliance and the standard features work well for us."

"The solution can scale well."

"This is a capable appliance and the standard features work well for us."

"The Zyxel Unified Security Gateway solution is stable and does its job effectively."

Cons

"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."

"FortiGate NGFW can improve technical support. The engineer who answers the technical support call, email, or phone call, whatever the medium may be. The response time is very bad."

"When we cluster the two Fortinet FortiGate boxes together we have some issues."

"Stability and technical support are the two major issues I have found with Fortinet."

"They need faster serviceability and more security features."

"They can probably improve the reporting feature. Reporting and report alerting are the main key features of this solution. They can always find ways to improve these."

"It should have a better pricing plan. It is too expensive."

"The solution lacks multi-language support."

More Fortinet FortiGate cons

"The log sections could be done more clearly."

"We have been facing issues with reporting."

"There is still room for improvement, and it's not advisable even if the organization has grown."

"It would be good if Analyzer would be part of the stock license, so even if a layperson is getting the device, he or she doesn't forgets about ordering the Analyzer because it's already there."

"I think content filtering is the area this product should improve. It's a little tricky to get put in correctly."

"We would like to improve the rules configuration in SonicWall TZ. Sometimes the rules don't work."

"I would like them to make the interface a little bit easier to use so you can find out where in the heck you're going instead of having to go to 15 different places to get something installed."

"The solution's antivirus checking could be improved so that we can have a deeper inspection of the packets."

More SonicWall TZ cons

"Although manageable, the user interface is a little bit slow and could be improved."

"The product has some scalability and data management issues where improvements are required."

"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."

"Sometimes it reboots when you least expect it, and that's the main issue."

Pricing and Cost Advice

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."

"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."

"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."

"The pricing or licensing of Fortinet FortiGate is quite effective as it offers different bundles that aggregate most required features, while also allowing clients the option to select specific components alone."

"Fortinet FortiGate IPS' licensing is quite simple to understand."

"There is a licensing fee; it is on a yearly basis."

"Setup costs and pricing depends on many variables, but it's mostly affordable."

"It is affordable. Palo Alto is much more expensive than Fortinet."

More Fortinet FortiGate pricing and cost advice

"The price is high compared to some other solutions."

"The prices are expensive."

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

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

"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."

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

"The product is not expensive, but it is not cheap."

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