CIO and President at Aim High! Inc.
Netgate doesn't come anywhere close to the scalability that its competitors do.

Featured Reviews

JA
Principal Cloud Architect - Software Engineer at a consultancy with 11-50 employees
Rapid VPN setup has connected offices in minutes and brings live insights for proactive issue control
What I appreciate the most about Netgate pfSense is the ease and straightforward nature of the platform. I can set up a new office in less than 10 minutes. The benefits of using Netgate pfSense are that I can set up VPNs in less than two to three minutes, and then just deploy the file across my networks, where everybody would be connected in less than an hour. The dashboards of Netgate pfSense bring all the necessary information that I need at a glance, and it is actually a live update every three to five seconds. It is spotless, and I have been able to catch issues before they hit operations.
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.
