Which one fits
Both govern AI agents, so the choice comes down to where your agents run.
Choose Noma Security if
- You need an inventory of every AI agent and tool in use across SaaS, cloud and developer environments.
- You want to stop agents that drift or get manipulated while they run.
- You want a vendor large companies already use. Noma says more than 10% of the Fortune 100 are customers.
Choose Zenity if
- Your staff build agents and apps in Copilot Studio, Power Platform or Salesforce, and security needs to see what they connect to.
- You want coverage for coding agents and personal AI agents as well as business platforms.
- You need MCP security and AI detection and response.
What buyers say
“Zenity is better for Copilot/SharePoint permission messes. Noma is better when autonomous agents in CRM/tools are the thing security can’t see.”

“Permissions hygiene is why copilots get grounded, that’s Zenity’s world. Agent prompt-injection in business apps is a different queue; that’s closer to Noma’s lane.”

“Noma gave us an inventory of agents and tools across SaaS, cloud, and developer environments, and it can stop agents that drift. Zenity looked closer for a shop built on Copilot Studio or Agentforce, which we are not.”

Noma Security (8.0 out of 10, Recommend) covers agents and AI tools across SaaS, cloud and developer environments and can stop agents that drift or get manipulated. Zenity (6.9 out of 10, Conditional recommend) is the closer fit when most of your agents are built in Copilot Studio, Power Platform, Salesforce Agentforce or ServiceNow.
