They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product.

We encounter issues sharing IP addresses with other companies using the software.

We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve.

The ZPA solution is private access. The focus is not so much on the iPad as on the ZPA. Certain clients have voiced concerns about having a device in the data center and the control plane directly leading to the cloud. They would prefer a solution without the tunnel and without an active device of a cloud provider in their data center, meaning their DMZ, which would require access to the private data center applications from the remote users.

When it comes to scalability, the IPsec could be improved. The GRE tunnel, obviously, supports a high amount and high bandwidth. In contrast, the IPsec still comes with limitations, particularly based on the access gateway side of Zscaler.
