Featured Reviews

Rohit Ghorpade - PeerSpot reviewer
Cloud Network Engineer at a insurance company with 5,001-10,000 employees
Identity-based perimeter control has improved security and supports reliable remote access
Currently, we are working with vendors such as Palo Alto Networks PA-Series, Cisco, Check Point, and Citrix. Palo Alto Networks PA-Series is a better firewall. Deep packet inspection and threat prevention basically comply with whatever traffic is incoming and outgoing through the firewall. I do not think anything improvement is required. The thing is that Palo Alto Networks PA-Series works mostly on a license-based model. If you want to utilize any feature, you have to purchase the license. For example, URL filtering requires a license purchase. It simplifies the implementation because LDAP server profile can be integrated. Basically, that simplifies the implementation of access rule or security policy.
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.
