Neo vs Zenity: AI endpoint control facts side by side
Short answer
Neo describes 1 of the four product control types on the pages we read and Zenity describes 1; they differ on on-device control, browser extension and AI or MCP gateway. On decisions, Neo decides on a tool call before it runs 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.

| Positioning | Agentic Software Control from Neo Security, Inc. (neo.ai, not Pulumi Neo): a live inventory of agents, models, skills, MCP servers and extensions on every endpoint, and runtime control that intercepts agent actions and allows, blocks or holds them for approval. Launched 20 July 2026 with $100M from Andreessen Horowitz and Bessemer; HQ Boston. | An AI agent security platform covering AI observability, posture management, exposure management, runtime boundaries, agentic identity, MCP security and AI detection and response, with a long list of SaaS and cloud agent integrations. |

- AI or MCP gateway: Neo is not in our sources; Zenity describes it.
- Rolls out through EDR or device management you run: Neo partly matches; Zenity is not in our sources.
- Can warn or ask instead of only blocking: Neo matches; Zenity partly matches.

Choose Neo if
- You want to hold agent actions for human approval on the device
- You want an audit mode before enforcing 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
Which limits should you check?
Neo
- Uses its own sensor rather than the EDR or MDM you run, and OS support is not listed on the pages we read.
- No price is published.
Zenity
- How it reaches endpoints is not detailed on the pages we read.
- No pricing published, and asking the user before an action is not described.
