Featured Reviews

Gary-Downey - PeerSpot reviewer
Director of Information Technology at a consultancy with 11-50 employees
Has provided built-in VPN tools and reporting features that streamline remote access and monitoring tasks
We do an outside-sourced threat prevention regarding the Threat Prevention features. I haven't run into areas that could be improved or cons versus pros for Untangle NG Firewall. I haven't done anything too advanced when it comes to the filtering, so I'm not sure what can be improved or added. I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules. These areas could be improved to make it a nine out of 10 or a 10 out of 10 for overall rating.
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.
