AI Access Security vs Noma: 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 Noma describes 1; they differ on on-device control and network or SSE proxy. On decisions, AI Access Security does not describe tool-call decisions on the pages we read and Noma describes some control over tool calls. 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 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
Which limits should you check?
AI Access Security
- Coding agents, MCP servers and local agent actions are not described on the page we read.
- The specific controls and actions are not detailed, and no pricing is published.
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.
