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.

Efficient bandwidth management and secure network access with a strong firewall

The primary use case of the Firebox mainly revolves around bandwidth management, unnecessary web blocking, application control, and protection against brute force attacks. It is also implemented for load balancing, SD-WAN, and branch-to-branch connectivity from one location to another. We also use…

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

"Its usability is good. We can easily navigate the system, and we have a very good user experience."

"This is a quality product with ok support, and it is better than the competition we've tried."

"The firewalls are valuable for threat prevention."

"The integration with Active Directory is one of the good features. Most of the customers are now looking for the Single Sign-on feature. So, being able to integrate Active Directory with the firewall is useful. It is also easy."

"Fortinet FortiGate offers several valuable features, particularly as an interface-based solution. Its design makes it easy to understand both incoming and outgoing network traffic through its interface."

"FortiGate is very simple to manage and easy to use."

"This solution made it very easy to manage our bandwidth."

"The multi-threat protection feature helps us secure our organization."

More Fortinet FortiGate pros

"The most effective and helpful features of WatchGuard Firebox, especially when purchased with the full suite of applications, are its bundled applications and subscriptions for comprehensive protection against various threats."

"We experienced that WatchGuard is easy to setup regarding VPN compared to other firewalls of other brands."

"The most valuable features are the VPN and web blocker security."

"The ease of use is most valuable. You can quickly train someone who hasn't seen a firewall in life. You can get people up to speed, and in a few months, they are able to manage this product very easily. It is a very user-friendly, scalable, and stable product. Its price is also spot-on."

"On a scale of one to 10, I would rate the technical support of the WatchGuard Firebox a 10."

"The solution has increased productivity with our outside salespeople being able to connect into their computers and use those remotely."

"The most valuable feature of this solution is traffic management."

"The features that I have found most valuable are the FireWall features. The management side of WatchGuard is quite easy because it supports two ways to manage it - by the web and the other one they call WatchGuard systems manager. I used to be familiar with WSM only, but they improved their GUI in the web browser and now it is much easier to do it within the web browser."

More WatchGuard Firebox pros

"The solution can scale well."

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

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

Cons

"It is stable, but its stability can be improved."

"Scalability for Fortinet FortiGate needs to be improved. SD-WAN security for this solution also needs some improvement."

"Web security solutions can be improved."

"Its load balancing feature could be easy to configure."

"I think they need to improve more in order to be a competitor with the leaders of the field."

"I would like to have SD-WAN as a part of the Next Generation Firewall. It would enhance high availability."

"Fortinet FortiGate needs to improve the protection, it did not prevent us from being attacked. Additionally, Fortinet FortiGate could provide more features for WAF devices. I should not have to purchase two solutions, it would be a benefit to combine these features into one solution."

"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."

More Fortinet FortiGate cons

"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."

"The only downside is that it is missing an API, that you can use to easily collect information from it."

"We use WatchGuard to manage our failover for internet. If a primary internet goes down, it does a failover to the secondary the internet. However, what it doesn't do so well is that if the primary internet has a lot of latency but it's not completely down, it doesn't do a failover to the backup in a timely manner."

"They need to stop the VLAN limitation. They have a VLAN limitation on the size of their boxes. It is the worst thing ever. They basically sell their boxes by the size and the number of VLANs it can handle, which is a real issue. You spend a couple of thousand dollars for a firewall, and you can only do 30 VLANs, which is extremely silly, as a matter of fact. It would be really great to have something for easier mass rule changes. It also needs a drag-and-drop function so that you don't have to constantly duplicate firewall rules. It would be nice to have such a feature because you got one WatchGuard, and you want to mirror its config and change a couple of things in another one and move some things around. It is not as easy as you would necessarily think. It is kind of expensive, and its pricing can be a little better for sure."

"In WatchGuard Firebox, the antivirus and malware detection systems are areas with shortcomings that require improvement since they are the most important elements of a cybersecurity tool."

"The licensing can be a bit expensive."

"It can have a couple of false positives, but after you add them to your allow list, it works fine. It could have better Mac support. I am pretty sure it doesn't have much support for Mac. It can be installed on a Mac, but it is not that good."

"The only problem I have with Firebox is the grouping issue. When implementing a rule using a group of IPs, it is not possible to do that directly."

More WatchGuard Firebox 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

"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."

"The tool's pricing is neither cheap nor expensive. Overall, I find it to be competitive in the market."

"I give the pricing a nine out of ten."

"It is less expensive than a Cisco solution."

"We pay for the solution annually."

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

"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."

"It is an expensive solution."

More Fortinet FortiGate pricing and cost advice

"Each one, for the primary unit, was $8,600 and the High Availability unit was $2,000. That's with three years of subscription and support and the Total Security Suite."

"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 think the tool is quite competitive compared to the other brands."

"It's an affordable tool"

"We license the WatchGuard Firebox annually. There are different types of subscriptions available. We are paying approximately $15,000 annually. The cost can increase if you purchase different subscriptions."

"The pricing is competitive."

"I think the larger firewall packages are much better because a normal firewall is not enough for these times. You need IPS, APT, and all the security features of a firewall that you can buy."

"WatchGuard Firebox is a cheap solution."

More WatchGuard Firebox pricing and cost advice

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