Zscaler Cloud Firewall provides in-depth visibility and log availability, aiding troubleshooting.
The firewall and VPN package offer comprehensive protection compared to other options.

CONS

Zscaler Cloud Firewall does not provide web browser isolation, unlike other solutions like Menlo, which limits integration capabilities.
There is a lack of Data Leak Prevention for email, only web filtering is covered, and some fundamental differentiating components are missing.
Integration with legacy systems could be improved, and there are issues with flexibility and visibility when creating inspection rules.

It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing.

The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release.

Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs.

I don't have the visibility of a control dashboard or a network management system.
