Agent 365 manages access. We govern performance.
Microsoft Agent 365 controls identity and access for Microsoft-native agents. Prefactor governs outcomes, costs, and scope across any platform. [1] [2]
What they do well - Agent registry via Microsoft Entra — identity-aware inventory of agents across the Microsoft ecosystem, extending a system most enterprises already manage.
- Access control and fine-grained permissions for agents built on Microsoft platforms, using the same policy model IT teams already know.
- Session activity visibility across Copilot Studio, Foundry, and Microsoft-native agents — useful for understanding agent behaviour within that stack.
- MCP enterprise allowlist — governed MCP connections across the Microsoft stack, a sensible approach to controlling tool access.
- Part of Microsoft 365 E7 — procurement simplicity for Microsoft shops. One vendor, one contract, one support relationship.
- Microsoft-native and select third-party agents — works with agents in the Agent 365 ecosystem, covering most Microsoft-built tooling.
Best for: enterprises deeply invested in Microsoft 365, Copilot Studio, and Azure AI Foundry who need governance within that ecosystem.
What we do - Outcome quality assessment: did the agent produce the right result for the task it was deployed to complete?
- Cost efficiency assessment: was the spend proportionate to the result?
- Scope adherence: did the agent stay within its approved boundaries, tools, and actions?
- Composite risk score from these signals, with customer-set thresholds that determine what happens next.
- Inline blocking and approval routing when risk thresholds are crossed.
- Agent registry and lifecycle governance from registration through retirement.
- Immutable audit log for regulatory review.
Best for: AI leadership, AI governance, compliance, and enterprise architecture teams that need continuous operational governance of production agents.
Microsoft Agent 365 may be sufficient if:
- Your agent stack is entirely or predominantly Microsoft-native
- You need governance integrated into existing Microsoft licensing and identity infrastructure
- Your primary buyers are IT and security teams already operating within the Microsoft stack
- Procurement simplicity and Microsoft support relationships matter
Consider Prefactor if:
- You are running agents across multiple platforms — AWS, GCP, Azure, custom frameworks
- You need to assess whether agents are delivering their intended business outcomes, not just whether they have the right access permissions
- You need governance that is architecturally independent of the platforms being governed — a requirement in many regulated industries
- You need a configurable approval chain that spans security, compliance, and governance teams rather than flowing through Microsoft identity management
- You need cost efficiency tracking as part of your governance posture

What does Prefactor do that Microsoft Agent 365 doesn't?
Prefactor assesses whether agents are performing as intended — outcome quality, cost efficiency, scope adherence — and acts on that assessment inline or through configurable approval routing. Agent 365 manages identity and access control but does not include a performance or ROI assessment layer.
Does Microsoft Agent 365 work with non-Microsoft agents?
Agent 365 is designed primarily for Microsoft-native agents (Copilot Studio, Azure AI Foundry) with select third-party integrations via the Agent 365 ecosystem. Prefactor is framework-agnostic and governs agents built on any platform.
When does Microsoft Agent 365 reach general availability?
Microsoft Agent 365 is expected to reach GA on May 1 2026, priced at $15 per user per month. It is currently in preview.
Is Prefactor independent of the Microsoft ecosystem?
Prefactor is platform-agnostic and architecturally independent of the agent platforms it governs. This independence is a deliberate design choice and a requirement in many regulated industries where governance must sit outside the systems being governed.
