The product's most valuable feature is complete SSL inspection.

The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy.

It's a robust solution with lots of helpful features like the sandbox, which quarantines every file before it's downloaded to the computer. 

IPS is more geared towards providing users access to the public internet, not those involving typical use cases which are cloud-or-SaaS-based. When it comes to user access to the World Wide Web, combined IDS/IPS does make sense. We provide access for this kind of traffic. This is primarily important for inbound traffic.
