Vasu Gala

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.

Provides reliable performance with strong features and simplicity

SonicWall TZ is user-friendly, admin-friendly, and a beautiful product. I have been selling SonicWall since 2007 without any issues. SonicWall has been working on it excellently. They are up to date, and their research team is good, making the box feature-rich. Based out of India, I have had some issues with their faulty channel policy. It's a very good product, an awesome product for those who want to use SonicWall TZ. You can bet on it, but check out the channel policies in India. They should check out the channels in the channel business. It's just a precaution, nothing more than that. Overall rating: 9 out of 10.

Alexander Azikov

It Manager at Diamond Braces

A robust appliance that is reasonably priced and straightforward to set up

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"It is a good product. It does what we want it to do so. I didn't find many false-positives or things like that. We mainly use the IPS and URL filtering features, and they are pretty good."

"The system is very easy to scale."

"Fortinet FortiGate is a stable solution."

"I rate this solution a nine out of ten."

"The wireless control is helpful."

"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."

"The reporting and monitoring are very good."

"Its interface is the most valuable. It is quite easy to manage."

More Fortinet FortiGate pros

"The VPN is quite useful for us, as well as the ATP."

"The solution is stable."

"Good VPN connection."

"I've found the technical support to be helpful."

"It lets me monitor in live time if someone is 'hogging' bandwidth."

"It protects against intrusion while allowing needed access."

"We like the unified threat management for defense-in-depth. We can terminate our site-to-site and remote access VPNs with it."

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

More SonicWall TZ pros

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

"The solution can scale well."

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

Cons

"Fortinet FortiGate can improve the integration with Active Directory. Additionally, I would like to have a Cloud Controller, such as they do in the Cisco Meraki solution."

"We can't identify which users are causing challenges when we have issues."

"There is an area for improvement in vulnerability management."

"The way everything is set up could be easier. Currently, people need a lot of experience and knowledge to administer it and to link it to devices."

"The solution’s stability could be improved because we sometimes faced some drops."

"There's room for improvement in the interface, especially following their upgrade to version nineteen."

"Security level could be increased."

"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."

More Fortinet FortiGate cons

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

"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 cost of the solution has room for improvement."

"The dashboard needs to be improved."

"The logs need improvement."

"We encounter issues while generating new reports."

"The quality of tech support can vary."

"The VPN that is available in the new version is a bit bulky and slower in speed."

More SonicWall TZ cons

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

"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."

Pricing and Cost Advice

"We saved a bundle by not needing all the past appliances from an NGFW."

"We pay for the license of Fortinet FortiGate IPS annually. There are not any extra costs."

"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."

"The pricing for the product is alright."

"The price of Fortinet FortiGate is reasonable."

"There is an annual license to use this solution. The prices have been increasing over the years."

"It could be more competitive and cost-effective."

"The price of Fortinet FortiGate is reasonable for an SME."

More Fortinet FortiGate pricing and cost advice

"The product pricing is relatively good, compared to other products, including the licenses."

"The price is fair for the solution for the quality you receive."

"The price of SonicWall TZ is good for medium-sized companies."

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

"It is an expensive solution compared to one of its competitors."

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

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

"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."

More SonicWall TZ pricing and cost advice

"This gateway is pretty cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
