Zscaler SASE Pros and Cons

Zscaler SASE Pros

Infrastructure and Network Engineer at Servomex Group Limited
I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway.

Zscaler SASE Cons

Infrastructure and Network Engineer at Servomex Group Limited
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. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler. Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best.

There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors.
