Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches

Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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.

Client activity has been monitored efficiently through in-depth log analysis and traffic filtering

I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

Quotes from Members

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

Pros

"Whenever we raise a complaint with FortiGate, their response and resolution times are minimal."

"There’s something magical about the way the flavors blend together, creating a dish that is both comforting and exciting."

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

"The support is good because, although the response time for tickets may occasionally take some time, at the end of the day they have always solved the issue at hand."

"One of the things that I like the most is it has a built-in SD-WAN solution - its price is included in the hardware."

"Overall, we've been pretty happy with the solution."

"The solution is stable."

"The main reason we chose Fortinet FortiGate was that the price was better than the competition."

More Fortinet FortiGate pros

"The most valuable feature is the GUI, especially the real-time bandwidth usage report. Also, its integration with WiFi access points is nice."

"Some of the most valuable features of the Firebox include web blocking, application control, protection against brute force attacks, load balancing, SD-WAN, and VPN support. These features help us manage and secure our network efficiently."

"It's user-friendly. And if you are using a WatchGuard device and you want to test that side of the software, it's quite easy to get the license to test it."

"We used to have an MPLS network which was a cloud-based firewall system and it cost us a small fortune every month, but when we implemented all these firewalls and got it all configured, up and running, we literally saved ourselves $10,000 a month."

"The most valuable are the VPN and proxy features."

"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 centralized console simplifies management for organizations with multiple Fireboxes."

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

More WatchGuard Firebox pros

"I'd rate the solution nine out of ten."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."

"The solution operates in the background seamlessly without the user noticing."

"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."

"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."

"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

More Zscaler Client Connector pros

Cons

"It does not have key authentication for admin access."

"In most cases, the IPS engine uses too many resources, which makes Fortinet FortiGate devices unstable."

"Fortinet technical support is lacking, as OEM support is slightly better."

"Fortinet FortiGate can improve performance. There was a huge challenge in terms of CPU and memory where the IPS engine would keep triggering. There were random spikes of overutilization in the CPU and memory resources. They have to work on CPU and memory stability considering these IPS engines. A few versions were very unstable."

"We have never encountered any issues with it. The price and deployment part of Fortinet FortiGate is good, but it can always be better."

"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."

"I believe there is room for improvement in machine learning and AI in Fortinet FortiGate. I would like to see more automation regarding AI and machine learning in Fortinet FortiGate."

"We have experienced a number of failures when trying to upgrade firmware and the process takes a long time. We only experienced this when doing major upgrades between versions."

More Fortinet FortiGate cons

"The reporting isn't so good. If they worked to improve this aspect of the solution, it would be much stronger."

"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."

"The main area for improvement in WatchGuard Firebox is exposing more of the technical configuration in the cloud management, as it would take away the need to do local management on those devices."

"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."

"There's always room for improvement, especially if the threats are getting more sophisticated and the IT department cannot sufficiently meet this kind of sophistication with their own knowledge and experience. Knowing that this solution can get up to the level of addressing a lot of these threats is something that everybody wishes for. If we look at the dark web and the lawful web, they are two opposites, and if these two good and bad collide in the world of the internet, you want the best possible product—especially if you cannot get to that point of knowledge. I am just an individual and end user, with limited knowledge of usage. That's why I say there's always room for improvement, from their side and also from mine, because by knowing exactly what they can achieve and the knowledge that they can get on an everyday basis, and the portion that is understandable to me, it's an improvement for them as well."

"The way Secure Sign-On authentication is happening needs to be improved. When the Secure Sign-On portal is turned on, anybody who comes into the campus, whether he or she is a staff member or a guest, has to go past the initial portal. One of the shortcomings is the username. It shouldn't allow permutations or combinations with upper or lower cases. For example, when there is a username abc, it shouldn't allow ABC or Abc. It should not allow the same username, but currently, two separate people can go in. Therefore, its authentication or validation should be improved, and the case sensitiveness should be picked up. If I have restricted someone to two devices, they shouldn't be able to use different combinations of the same username and get into the third or fourth device. It shouldn't allow different combinations of alphabets to be used to log in."

"The usability could be better, but it is definitely manageable."

"They are working on cloud-based options. However, they do not have the options fully functional in their solution at this time."

More WatchGuard Firebox cons

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."

"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."

"I rate this product nine out of ten because I have seen some minor instability issues after updates and some room for UI improvement for deeper analytics, with instances of major issues after updating the GCC that required rollbacks."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

More Zscaler Client Connector cons

Pricing and Cost Advice

"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."

"The license of Fortinet FortiGate should be reduced."

"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."

"The price of Fortinet FortiGate is the lowest in the market."

"It is less expensive than a Cisco solution."

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

"FortiGate Next-Generation Firewall is cheaper than Cisco or CheckPoint."

"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."

More Fortinet FortiGate pricing and cost advice

"For what we use, the tool's price has been reasonable, but it is not the cheapest. The tool has been quite reasonable."

"The cost three years ago was about $800."

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

"Cheap."

"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."

"The two larger devices are about $1,000 each and the smaller ones are about $500 or $600 each... It's cheaper and you have more control because it's self-managed."

"Very competitive pricing regarding throughput compared to other alternatives."

"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."
