Enables customers to manage security effortlessly with intuitive features and easy integration

In terms of improvements for Fortinet FortiGate, they could offer evaluation licenses, as compared to Meraki, which provides a 90-day evaluation. In Fortinet FortiGate, they do not provide standard evaluation licenses; instead, we need to request them from the OEM through the account manager for POCs. If we want to conduct a demo, we need to work with real hardware. In comparison to Cisco, we have DCloud, which helps with providing demos to customers, but in Meraki, I need to reach out to them, book a lab, and they need to provide all the hardware. I need remote access and L3 engineers to program it; only then can I offer a real-time demo to the customer.

Professional Services Engineer at Nex7 IT

Centralized security management has improved VPN reliability and simplified daily operations

WatchGuard Firebox is a strong and reliable platform overall, but there are a few areas where improvements could make the experience even better. One area is the user interface and navigation in some management tools. While the platform is powerful, certain configurations and troubleshooting workflows can feel less intuitive compared to some newer cloud-native firewall platforms. Another point is reporting and log analysis. Although the logging features are very useful, deeper analytics and more customizable reporting dashboards would make security monitoring much more effective. Firmware upgrades and policy synchronization can sometimes require careful planning to avoid security interruptions. Overall, the core security and VPN functionality are very solid, but improving usability, reporting, and automation would make the platform even stronger. One area that could be improved is the learning curve for new administrators. While experienced engineers can work with the platform effectively, some advanced networking and security configurations can be a bit complex for junior technicians. More guided configuration workflows, smarter recommendations, and simplified troubleshooting tools would make onboarding easier. Another improvement would be more flexible reporting customization for executive-level and client-facing reports.

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

"We have a redundant setup for failover, however, it has not had to fail over ever and we have not had a capacity issue."

"The user interface (UI) is very, very good."

"The cost of the solution is very good in the context of other, similar solutions on the market."

"Fortinet FortiGate is a simple solution, and the integration with other solutions in the Fortinet portfolio, such as the Security Fabric integration, is competitive."

"I think that the UTM features are the most value, as it truly protects my infrastructure."

"Fortigate represents a really scalable way of delivering perimeter network security, some level of layer 7 security, WAF, and also a way to create a meshed ADVPN solution."

"I find that Fortinet FortiGate is pretty easy to use and integrated, offering many features in one box at a decent price compared to other enterprise vendors."

"It's an easy solution to set up."

More Fortinet FortiGate pros

"Firebox is 10 out of 10 at what it does."

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

"We use the on-premises deployment model. It's a great product."

"My advice for people that wants to implement the solution is that it is very good, you get value for money, and you will be well protected."

"The Firebox offers valuable features such as network security, URL filtering, UTM features, intrusion prevention and detection, and authentication."

"WatchGuard has been mostly cost-effective compared to other firewall systems that are out there, given the power that it has and the ease."

"I like the High Availability features of the newest ones I'm using because they allow a firewall to fail and still be up and running."

"It gives us a higher sense of security, there is an easier workflow as well, and it saves us a couple of hours per person per week."

More WatchGuard Firebox pros

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

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

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

"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."

"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."

"Zscaler Client Connector has eliminated VPN bottlenecks and outages, improved user productivity with instant secure access, and reduced help desk tickets related to VPN issues, overcoming 60% of VPN-related problems while allowing faster onboarding of remote users and better enforcement of zero-trust security policies."

Cons

"While FortiGate is cheaper than most other solutions, we're seeing increased license renewal costs. Most of our clients are asking for more significant discounts because the price is going up."

"Its web interface needs to be more stable, and more functional, through the variety of browsers."

"Part of the setup was straightforward and other parts were complex. They need to work on feature placements and menus."

"Their licensing should also be improved. The activation or renewal of the product should be done from the date of renewal, not from the date on which the license expired."

"From a support perspective, I had more issues that I didn't think the person on my case handled the way I was expecting. We called them for a geolocation issue and we didn't get any proper assistance."

"The pricing could be a bit better, especially when you consider how they have the most basic offering priced."

"It should be more stable. There should be full integration within Fortinet products themselves as well as with other third-party products. Especially when you're not dealing with SIEM and the correlation of the security box, we want Fortinet to be able to share that information with as many other products as it can."

"It's one of the more expensive brands."

More Fortinet FortiGate cons

"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 interface is not the best."

"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."

"Some of the configuration options are somewhat confusing."

"WatchGuard Firebox has room for improvement in security services or security modules and the integration with other products."

"When it comes to live-monitoring, the user-interface could be improved to make things easier."

"Cloud-based central administration of all devices from one point would be nice (although there is always an added risk regarding this)."

"The user interface and configuration can be improved."

More WatchGuard Firebox cons

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

"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 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."

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

"Zscaler Client Connector is not low in cost; it is definitely on the higher side."

Pricing and Cost Advice

"It's a year based license."

"Each feature costs money, so it is important to study your needs."

"The licensing scheme of Fortinet is better than Cisco. It is more logical."
