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.

CEO at Kapstone Technological Services LLP

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.

"Fortinet offers comprehensive security solutions for various purposes."

"The usage in general is pretty good."

More Fortinet FortiGate pros

"We are able to block whatever we want to block by using this product. It provides all required security features, such as content filtering, VPN, in one box. Before switching to SonicWall, we had specified all required features."

"I have found the stability of this product to be excellent."

"The solution's VPN is very good for stability and detecting threats."

"It's a stable solution."

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 should improve the VPN tokens."

"I think there could be more QoS features"

"Some of the software stability could improve."

"The support structure needs to be improved because every time we contact them, there is a delay in the response."

"The solution is not scalable."

"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."

"The licensing could be improved as it is a little confusing and too granular for Fortinet FortiGate."

"The updates Fortinet provides are sometimes unstable."

More Fortinet FortiGate cons

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

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

"The user support could be improved because you have to go outside to get that kind of support."

"The technology in this particular version is very old."

More SonicWall TZ cons

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

"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."

Pricing and Cost Advice

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."

"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."

"Easy to understand licensing requirements."

"These boxes are not that expensive compared to what they can do, their functionality, and the reporting you receive. Fortinet licensing is straightforward and less confusing compared to Cisco."

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

"Compared to other firewall products, it's a little cheaper in terms of pricing."

"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."

More Fortinet FortiGate pricing and cost advice

"You need to purchase multiple licenses to manage multiple devices which is cost-prohibitive for the value you would receive."

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

"The prices are expensive."

"The firewall with the servers costs about 80 pounds a month. We get the device, and it is replaced every two or three years."

"The solution is 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."

"Licensing fees are on a monthly basis."

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

More SonicWall TZ pricing and cost advice

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

"This gateway is pretty cheap."
