AI Access Security vs Zenity: AI endpoint control facts side by side

Short answer

AI Access Security describes 1 of the four product control types on the pages we read and Zenity describes 1; they differ on on-device control, network or SSE proxy and AI or MCP gateway. On decisions, AI Access Security does not describe tool-call decisions on the pages we read and Zenity decides on a tool call before it runs. 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 AI Access Security if

You already run Palo Alto Networks Prisma Access and want GenAI app controls in the same place
Your main concern is employees using many GenAI web apps rather than agents on laptops

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
