Featured Reviews

Jennifer  Bernice - PeerSpot reviewer
Dotnet Developer at Kohl's
Centralized firewall management has saved time and improved network security across locations
Barracuda CloudGen Firewall could be improved as it has a very high learning curve. It is definitely not a one and done firewall, as a one and done firewall requires a lot of dedicated time to get the machine running the way you want. To improve Barracuda CloudGen Firewall, there should be a lot of tutorials and videos online to help new users. Multiple ways to configure for the same service or feature takes time to determine your customized build. In addition to previous points, the interface can sometimes be clunky when trying to determine how it is organized or arranged.
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.
