Neither is scored on this site. Zenity describes 1 of four product control types and Zscaler 1 on the pages we read, and they differ on 9 recorded facts. Which fits depends on the AI tools people use, your devices, where the work happens and whether you block or guide; the finder checks those.

Which of the two decides on a tool call before it runs?

Zenity: Matches. Zscaler: Not in our sources. Warn or ask: Zenity Partly, Zscaler Not in our sources.

Do Zenity or Zscaler publish prices?

Zenity: Not published. Zscaler: Not published (demo request).

Zenity vs Zscaler: AI endpoint control facts side by side

Short answer

Zenity describes 1 of the four product control types on the pages we read and Zscaler describes 1; they differ on on-device control, network or SSE proxy and AI or MCP gateway. On decisions, Zenity decides on a tool call before it runs and Zscaler does not describe tool-call decisions on the pages we read. We do not score either; the right choice depends on the AI tools people use, your devices, your current stack and whether you block or guide.

Choose Zenity if

Microsoft 365 Copilot, Copilot Studio, Salesforce or ServiceNow agents matter as much as laptops
You want an MCP gateway that can modify a tool call, not only block it

Choose Zscaler if

You already route traffic through Zscaler and want GenAI controls there
Your main risk is sensitive data pasted or uploaded into GenAI web apps
