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

"It is a very user-friendly solution. Moreover, Foritgate offers good performance."

"Fortinet offers comprehensive security solutions for various purposes."

"It's super reliable. I don't think I've ever had a reliability issue with it."

"The features that we have found most valuable are the SSL VPN and the User Portal."

"The interface is user-friendly, so it's easy to add policies and block traffic."

"The CLI is robust and powerful, enabling rapid, consistent changes via SSH."

"Fortinet FortiGate has a very simple configuration, is easy to set up, and includes SD-WAN features at no additional cost."

"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."

More Fortinet FortiGate pros

"I find WatchGuard Firebox provides very good value, with configuration migration between boxes, more flexible traffic management, best performance, strong security layers and dependencies, protocol-oriented design, rapid deploy for remote configuration, total protection for inbound and outbound traffic with deep understanding of the traffic, powerful DNS security for both network and mobile users, SD-WAN features that manage line quality, extensive exception handling, and a rich set of integrated security services like Access Portal, Application Control, APT Blocker, Botnet Detection, DLP, Gateway AntiVirus, DNSWatch, Geolocation, IntelligentAV, IPS, Reputation Enabled Defense, spamBlocker, Threat Detection and Response, and WebBlocker."

"I appreciate the interface and the client of WatchGuard Firebox the most, since many firewalls do not have a client to connect and instead rely on CLI only, and I also use the fully managed management server and appreciate the feature to schedule operations."

"It saves us time in the respect that we now have the template built for it so we can get in and get it done. We've had much less problem supporting Voice over IP technologies from different companies. Because our client base has grown over the years, we're probably saving 20 to 30 man-hours a month now that we've got this on a good stable level."

"WatchGuard is easy to implement and inexpensive. When we get a bulk-off license, we get a very discounted price that is competitive with alternative or competitor solutions."

"Their support is excellent, and the stability is very good."

"The most valuable features of the WatchGuard Firebox are all the security and updated features. You are able to configure the solution from the cloud platform and the application and web interface are very nice."

"WatchGuard Firebox offers a satisfying VM and hardware"

"WatchGuard Firebox is easy to configure and has a nice user interface."

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."

"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 would like the deployment and integration of this product to be easier. We should be able to deploy the features more easily and have different types of access."

"Its reporting capabilities can be improved. It should have some out-of-the-box reporting capabilities and some degree of customization."

"I would like to see more advanced developments of a wireless controller in the future."

"At the moment, the main concern is the pricing and the type of licensing."

"Right now, it's not really scalable, but it's okay for us. However, looking ahead to three years from now, we might have a problem with scalability. We foresee a little risk down the road. The stability is okay for now."

"When it's overloaded, it works slower and overheats."

"The firmware updates are sometimes not stable. The stability issues can vary, sometimes happening once a month or quarterly. New firmware updates can occasionally introduce bugs, causing some policies to fail. We then have to raise a ticket, and Fortinet usually provides a fix within a few days."

"The solution could have licensing fees reduced in the future."

More Fortinet FortiGate cons

"It doesn't offer the best protection and it's incompatible with a lot of China's websites. It makes a lot of mistakes when it is detecting items as it's not recognizing items correctly."

"In terms of what could be improved, I would say their web blocker feature. It is still quite a confusing setup, especially when you want to filter out a particular category for granularity. For example, you do not want to filter Facebook but you do want to filter Facebook games only. It can be done, but the process to do it is very confusing."

"We use WatchGuard to manage our failover for internet. If a primary internet goes down, it does a failover to the secondary 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."

"There is a problem with the RAM - it's eating up resources. The RAM utilization sometimes reaches up to 80% - 95%, and what we do is just restart the firewall."

"The software base, the management piece that goes onto a server, is not as user-friendly as I would like."

"One area for improvement is the limitation in the product portfolio compared to competitors like Fortinet, which offers a broader portfolio including Authentication, VPNs, FortiMail, Sandbox, and Email Security."

"It would be wonderful if the WatchGuard team develops nice products for threat intelligence."

"The licensing can be a bit expensive."

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."

"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."

Pricing and Cost Advice

"The product is expensive. I rate its pricing a six out of ten."

"The pricing is comprehensive and clear. You can easily understand what you are purchasing, including which features correspond to each license and maintenance contract. Overall, the information is straightforward. Additionally, compared to other vendors, their prices are competitive."

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

"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."

"Compared to Palo Alto, which we have used in the past, pricing and licensing are okay."

"We are on an annual license to use Fortinet FortiGate."

"It's an expensive solution"

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

More Fortinet FortiGate pricing and cost advice

"WatchGuard Firebox is a cheap solution."

"I think we might be subscribed to one or two of the premium features."

"The subscription that was purchased is for three years, but it is usually for one year at a time."

"The solution is not expensive and customers pay for a yearly license."

"The primary reason that we went with Firebox was its cost. It is very economical and it provided us with all the security functions that we were looking for at the time. And the throughput was more than what we required, so it was a very cost-effective device to deploy on our network."

"It costs me about $800 a year."

"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."

"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."

More WatchGuard Firebox 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."
