Room For Improvement

Featured Reviews

Ehab Ali - PeerSpot reviewer
Senior Presales Consultant at a computer software company with 1,001-5,000 employees
Unified security fabric has simplified multi-country deployments and strengthened threat response
FortiGate VM delivers exceptional performance and security with no degradation of service or protection (same features as the HW option). As part of the Fortinet Security Fabric, it extends across clouds and distributed locations, mitigating blind spots in virtual infrastructures. FortiGate VM can be rapidly deployed, managed through a centralized platform, and offers a range of purchasing options to suit every need. Also, FortiGate VM offers versatile deployment options across both public and private clouds, supporting all major public clouds including AWS, Azure, and Google as well as most hypervisors such as VMware, Hyper-V, and KVM. These deployments enable organizations to create scalable, high-performance firewalls that can be tailored to different virtualized environments and hyper-scale public cloud infrastructures. FortiGate VM integrates seamlessly with various infrastructure as code (IaC) tools such as Jenkins and GitLab, supporting security as code practices.
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.
