Extremely stable and very scalable
The solution was far too expensive, which is why we ended up moving to a new vendor. The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration. AT&T could simplify its user interface and log on. Typically, where you log on is independent of the solution, as long as you have had authorization. With this solution, you needed to configure a single entry point which wasn't ideal. The solution should have been able to integrate more easily with Microsoft.

Zero trust access has transformed remote connectivity and now simplifies secure app usage
Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The stability of the solution is its most valuable feature."
"Overall, the solution does a pretty good job at web filtering."
"The user interface of Zscaler Private Access is excellent. With proper knowledge and expertise, one can efficiently handle intricate enterprise environments without feeling overwhelmed. This leads to exceptional productivity for managed service providers. The user experience is remarkably streamlined, enabling the management of even the most complex enterprise setups without any excessive complications."
"As a cloud-based service, it is very easily implemented."
"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."
"The ZPA is a unique feature which offers VPN along with all the additional security needed."
"The product’s most valuable features are inbound and outbound scanning and API control."
"The most valuable features of Zscaler CASB are API integration and DLP."
"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."
 

Cons

"The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration."
"We'd like to have two-factor authentication that is quite simple."
"The scalability is a weak point right now. Its scaling capabilities are lacking, and we'd like to see that improve in the future."
"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."
"The granularity in blocking is not sufficient, as new domains are automatically blocked for 30 days without further information."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
"It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."
