Vasu Gala

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.

Carlos Snel

Director at Aquila ICT Solutions

Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management

The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.
