Bulletproof Agent 365 Governance and Security Readiness Accelerator

Microsoft Agent 365 is now generally available for commercial use and provides a centralized control plane for AI agents across the enterprise. As organizations adopt more agents and copilots, they often face limited visibility, inconsistent ownership, weak lifecycle controls, and uncertainty around what data agents can access and what actions they can take. This accelerator helps organizations establish the governance, identity, security, and operational foundations needed to adopt AI agents with confidence.

Built for customers preparing to operationalize AI at scale, this accelerator aligns Microsoft Agent 365 with Microsoft Entra Agent ID, Microsoft Defender XDR, Microsoft Purview, and Microsoft Security Dashboard for AI to help observe, govern, secure, and manage AI agents across the organization.

It helps answer the key questions leaders need resolved before agent adoption accelerates:

Do we know which AI agents and Copilots exist across our environment today, and how will Microsoft Agent 365 surface them?

Who owns each agent, who sponsored it, who approved it, and who is accountable when something goes wrong?

How will we extend identity, conditional access, and lifecycle controls to agent identities under Microsoft Entra Agent ID?

How will we detect, block, investigate, and hunt suspicious AI agent behaviour using Microsoft Defender XDR?

What governance and security operating model should we adopt before agent volume grows?

What is the right sequence of decisions to make agent adoption safe and defensible?

AI Strategy and Current-State Discovery

Discovery sessions assess the organization’s current AI posture, including:

Current AI usage, governance posture, tool sets, skills and education, and rollout planning.

Advice on rollout strategy and the importance of identity, data security, and operational governance.

A current-state review of where AI agents and Copilots exist today, who owns them, and how they are being introduced.

Governance and Identity Readiness

A readiness overview covering agent security, compliance, identity, governance, and operations.

An evaluation of governance gaps across approval workflows, ownership models, sponsor accountability, lifecycle management, and monitoring.

A review of identity foundations using Microsoft Entra and how they extend to agent identity under Microsoft Entra Agent ID, including agent identity blueprints, sponsors, granted permissions, sign-in logs, and Conditional Access applicability for agent identities.

Microsoft Agent 365 registry and agent inventory review, including agent ownership, sponsor, and approval model.

A review of data-risk context for agents using Microsoft Purview signals (DSPM, DLP, sensitivity labels, audit) where available.

An operating-model recommendation covering roles, responsibilities, review cadences, escalation paths, and decision rights.

A prioritized roadmap of recommended actions: what to do first, what to defer, what to plan for.

Runtime AI Agent Security (Microsoft Defender XDR)

The engagement also evaluates whether the customer can detect, investigate, and respond to suspicious AI agent activity. Coverage includes:

Microsoft Defender AI agent inventory and posture assessment.

AI agent detections, alerts, and runtime protection for supported agent actions.

Detection readiness for unsafe tool usage, credential exposure, data exfiltration attempts, and prompt-based attacks.

AI Security Threat Model

An AI security threat model is included to provide security leaders with a practical view of readiness across:

Prompt injection and indirect prompt injection.

Excessive agency and unsafe tool invocation.

Data exfiltration through agent actions.

Agent-to-agent trust boundaries.

Sensitive information disclosure.

Over-permissioned connectors and tools.

Model, plugin, connector, and tool supply chain exposure.

Monitoring gaps for AI activity.

Microsoft Security Dashboard for AI

Where available, the engagement includes an executive AI risk summary supported by Microsoft Security Dashboard for AI and evidence from Agent 365, Entra Agent ID, Defender, and Purview. This helps consolidate AI risk insights across Microsoft and third-party agent environments.

Copilot Control System Alignment

Recommendations are mapped to Microsoft Agent 365 and the Microsoft Copilot Control System across governance, security, management controls, and reporting, giving customers a clear path from assessment to action. Bulletproof has advisory experience in AI readiness, Microsoft 365 Copilot enablement, Microsoft Purview governance, and Microsoft Entra identity. This accelerator extends that expertise to help organizations address the governance and security requirements of Microsoft Agent 365.
