Our take
What our shortlists say about the one we picked.
- Zscaler AI-SPM
Best for: Zscaler customers running AI on cloud platforms
This is a close match for the core job of the list, because it starts from the cloud AI platforms where your models and data actually sit. It plugs into Zscaler Data Security, so it pays off most if you already run Zscaler, and you should check how much of the value holds up without it.
