It is well suited for large corporations for granularity on users' roles, security levels for each application, and for logging in with an extra security layer. For doing demanding network tasks, like downloading a large set of data or for streaming, it could get slower than with a direct connection.
The tool is, for the most part, very intuitive. Most of our issues so far (working through them with our Resident Engineer) are the one-off applications. We are working on some exemptions to make them functional. Besides that, the team loves the tool and how it can provide better security than our previous tool.
Application Segmentation and Listener Configuration - The way applications are defined and listened for is fundamental to ZPA, but can be a source of frustration, especially when dealing with legacy or non-HTTP protocols
The ZCC is the user's primary gateway, but its control over local system network behavior can sometimes clash with enterprise requirements.
Few things stand out. The ease of access: It very convenient - one click to open add details and done. Packet capture: Can't talk enough about this feature. Troubleshooting private access is always problematic,but this feature helped a lot. One thing that can be improved is early warning about expiring authentication
I wasn't a part of the decision process to use Pulse Secure. I believe NordVPN Teams and ExpressVPN are both far superior products. Modern UI (Pulse Secure's UI is incredibly outdated), less reconnects, cheaper, less hacks (On April 20, 2021, CISA issued an "Emergency Directive on Pulse Connect Secure"), and simply faster overall connection speeds.
All of these tools are for different needs. Zscaler Private Access being for internal seems very simple as it really only allows filtering up to L4 whereas ZIA allows for filtering up to L7. ZDX often tries to give insight into the environment but since it only works with preconfigured items, that then means when a new problem shows up - ZDX isn't helpful troubleshooting postmortem. For the internal side of the house - Zscaler Private Access' strength is its simplicity to configure.
Positive: We have now charged users internally for the service
Negative: Dealing with users who also have the Zscaler Client Connector for their company, can cause confusions
Negative: Enabling the Zscaler Internet Access entitlement has been a major headache for us because Zscaler Private Access users can't autheniticate through ZIA on a non corporate device.
