Choose Noma if

Agents run on laptops, in SaaS and in apps you build, and you want one place to see them
You want discovery through existing EDR or MDM without a new agent

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

Which limits should you check?

Noma

A watch-only or simulation mode is not described on the pages we read.
Decisions on individual tool calls are described less specifically than discovery, and the only public price is a $200,000 a year marketplace listing.

Zenity

How it reaches endpoints is not detailed on the pages we read.
