Reviews from Real Users
Below are some reviews and helpful feedback written by Zscaler Internet Access users.
A Service Manager at a construction company says, "There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. For our needs, the cloud-native proxy architecture is a very good solution. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
Owen N., Security Architect at Claro Enterprise Solutions, explains that the solution’s most valuable features include “The integration of the gateway that inspects all ports and protocols. So, there is threat prevention; The cloud sandbox; VNS security; Access control that will protect URL filtering and the cloud firewall; Data protection that will protect your gateway, like your CASB or your cloud DLP; The capabilities of this will point your traffic to Zscaler Cloud.”
An Architecture Senior Manager at an insurance company mentions, "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go." He also adds, “The solution provides quick access to cloud services, securing our data and allowing us to inspect all our traffic.”

| Principal Security Architect at Deloitte | 4.0 | We use Zscaler Internet Access to secure internet-bound traffic and enhance data loss prevention. Its robust features improve security and operational efficiency, offering significant cost savings. However, integration with other solutions and technical support response time need improvement. |
| Group IT Manager at a wholesaler/distributor with 10,001+ employees | 4.5 | I use Zscaler Internet Access in my organization for secure web browsing and traffic filtering. The analytics and SSL inspection are invaluable for network visibility and data security. However, integration with internal monitoring systems could be more streamlined. |
| Regional Manager at Orange | 4.0 | I find Zscaler Internet Access valuable for its reliability, availability, and global reach, though its high cost and technical support need improvement. Customers sometimes prefer more flexibility, particularly regarding SSL inspection, impacting user experience. |
| Assosiate Vice President at Novac Technology Solutions | 4.5 | I've used Zscaler Internet Access for over three years to secure endpoints and control web access, finding its application and CASB features effective, though the admin console could be faster; overall, it’s improved our security significantly. |
| Cloud Advisory Senior Manager at a tech consulting company with 10,001+ employees | 4.0 | I find Zscaler Internet Access scalable, stable, and well-suited for complex use cases across sectors, though high-bandwidth demands can be challenging. Its hybrid integration, strong security, and effective support make it a reliable, negotiably priced solution. |
| Cyber Security Architect at a manufacturing company with 1,001-5,000 employees | 4.0 | I’ve used Zscaler Internet Access for three years to secure remote and on-prem users. It offers strong security, useful logging, and SSL inspection, though setup took three months and could improve with simpler configurations and better pricing. |
| Consultant at Essentra PIC | 4.0 | Zscaler Internet Access enhances our security posture through role-based access control and SSL inspection, while reducing costs and infrastructure needs. However, improvements are needed in traffic categorization and deployment processes to better manage exceptions and differentiate network types. |
| Network manager admin at Yamaha | 3.5 | We use Zscaler as a secure internet proxy for 3,000 users, valuing its traffic filtering, web security, and threat protection features. We've experienced issues with proxy IP blocking and cloud performance. We chose Zscaler over Fortinet for centralized control. |
