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.

Network protection has improved with stronger VPN connectivity but administration remains complex

Deploying WatchGuard Firebox was quite easy, but we have had some problems regarding the VPN and the administration of the tool and the two firewalls that we have. When comparing WatchGuard Firebox with our previous solution, Palo Alto, we have had some problems in administration because of the tools. I think that they have some aspects in their system that are cloud-provided, but they also have an on-premise solution, which makes this combination good. Although I should say that when compared to Palo Alto, we have taken a step backwards. In general, I would rate WatchGuard Firebox around 6-7; it is a good firewall, but they lack good administration tools. We experience many problems with the performance and administration tools on the web, including several issues with VPNs.

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

"The best features of Fortinet FortiGate are that it does the job effectively and protects our environment."

"The scalability is good in Fortinet FortiGate."

"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."

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

"One of the best features of Fortinet FortiGate is that it's a very powerful equipment that gives many security features in a single box with good performance, and the user interface is friendly to use and configure."

"The simplicity of the configuration and the stability of the product are most valuable. The VPN concentrator is very useful."

"The VPN is the most valuable feature."

"The product's most valuable feature is the ease of deploying IoT security with a single click. Additionally, the frequent updates to the online database ensure that our security measures are always up to date, enhancing our protection against emerging threats."

More Fortinet FortiGate pros

"When you download the executable file from the internet, it automatically sandboxes to make sure it's not doing anything incorrectly."

"It also provides us with layered security. It has onboard virus scanning features that allow it to scan before something gets to the host. It will also stop a person from going to a site that is known to be bad."

"We had many bottlenecks before deploying WatchGuard Firebox, but when we switched to a higher version of our firewalls, the bottlenecks were solved."

"The GUI is easy and intuitive."

"The Dimension control, the one-spot reporting and control, has been nice. It's been easy to go in and make sure people are doing what they're supposed to be doing and that only the right stuff is getting in."

"If there is any conflict, the reporting feature will kick out all types of information, which is great."

"It's hard to pick one feature over another. But if I had to pick one, the UTM would be the most valuable because of the notification. I get notified via email if there is any type of threat detection or alert, telling me something is wrong."

"The reports are detailed."

More WatchGuard Firebox pros

"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."

"The solution can scale well."

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

Cons

"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production. Other issues relate to isolation with Cisco products and your server."

"They can add automation for monitoring and policy optimization on the firewall. I think using AI to do some optimization on the policies would be beneficial, such as providing alerts about policies that haven't been used for a long time or identifying overlapping policies."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"The product does need better support in the cloud environment. It's not exactly cloud-native right now."

"FortiGate is really good. We have been using it for quite some time. Initially, when we started off, we had around 70 plus devices of FortiGate, but then Check Point and Palo Alto took over the place. From the product perspective, there are no issues, but from the account perspective, we have had issues. Fortinet's presence in our company is very less. I don't see any Fortinet account managers talking to us, and that presence has diluted in the last two and a half or three years. We have close to 1,500 firewalls. Out of these, 60% of firewalls are from Palo Alto, and a few firewalls are from Check Point. FortiGate firewalls are very less now. It is not because of the product; it is because of the relationship. I don't think they had a good relationship with us, and there was some kind of disconnect for a very long time. The relationship between their accounts team and my leadership team seems to be the reason for phasing out FortiGate."

"While the security is good, we'd always prefer if it was even better to ensure protection."

"Someone without certification and experience with other firewalls might find it a bit more challenging to grasp the FortiGate format and its platform layout."

"The solution needs to integrate VPN features."

More Fortinet FortiGate cons

"The solution isn't what I would consider feature-rich."

"We were able to take from an older configuration, build a new one quickly, and get it up and running, which didn't take long, but there was some pain around it."

"WatchGuard technical support requires a license."

"The level of support from WatchGuard is not as good."

"The documentation for the System Manager/Dimension configuration, could be a little bit clearer... The use case where you have multiple sites with multiple firewalls, and one site that has the System Manager server and the Dimension server, wasn't really well defined. It took me a little bit of digging to get that to actually work."

"Its graphical user interface could be improved because not everybody is technical. There is a lack of knowledge, and they can give some training for this solution."

"Last year, I had an issue with one of the Fireboxes going down. It was overheated, because my server room became overheated and this fried it."

"Websense is an application that monitors and filters internet traffic. Websense was derived from WatchGuard. But when you go to WatchGuard to actually implement that particular feature, you have to use some type of additional feature and you have to pay for it, unfortunately. I think it should be free or free in the WatchGuard box itself, as an option. It would be nice if they didn't charge us for that."

More WatchGuard Firebox cons

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

"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."

Pricing and Cost Advice

"Fortinet FortiGate is reasonably priced."

"It's not the cheapest, but it's value for money. Given everything we've got out of it: the DMZ port, the VPN, and the high availability, it's a pretty reasonable price."

"Its pricing is good. It's average or normal as compared to Palo Alto and Check Point firewalls."

"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."

"Pricing and licensing is a little bit complicated in FortiGate. They are always on the higher side. This is one issue that we always raise with the company that they should reduce the price according to Indian market requirements. There are no costs in addition to the standard licensing fees."

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"It was worth the money overall. It's good value."

"The Fortinet FortiGate security features cost approximately $1,500 a year. The firewall itself doesn't have a recurring cost. It's the security features on top of that that you pay for."

More Fortinet FortiGate pricing and cost advice

"I would rate the pricing at seven out of ten. As for the licensing costs, we typically have yearly licenses for our clients, but there are no additional costs beyond the standard licensing fees."

"We are utilizing an MSP licensing model and are content with the minimal amount spent on the devices rather than committing to long-term licensing."

"I buy a three-year renewal on the main device, which is usually around $3,000 to $4,000. They usually upgrade the device when I do it. You get a big discount when you do three years."

"We only license our corporate one and the one we have at our DR site, we don't worry about the branches. It doesn't pay for us to license the ones at the branches. What they charge for what they call basic maintenance is extremely high for those little fireboxes."

"It's in the medium range. Its price is pretty good considering the functions and add-ons that are used."

"The price is very good."

"We had a trade-in offer at the end of our first three-year term. As a result, we pretty much got a free device by buying the three-year subscription. It was around $3,000 for the three-years."

"They license it. When we buy it, we buy it with a three-year license. That's the most cost-effective way to do it. So, if you're going to buy it, then buy it with the three-year licensing."

More WatchGuard Firebox 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."
