Featured Reviews

Abhishek Saini - PeerSpot reviewer
Professional Services Engineer at Next7 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.
Carlos Snel - PeerSpot reviewer
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.
