Bloom vs Zenity: AI endpoint control facts side by side
Short answer
Bloom describes 0 of the four product control types on the pages we read and Zenity describes 1; they differ on AI or MCP gateway. On decisions, Bloom describes some control over tool calls 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 Bloom if
- Your first worry is unvetted extensions and packages arriving on developer machines
- You want an inventory of everything on the endpoint before you write AI-specific rules
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
