There is no universal winner. Choose the platform that fits your existing identity, cloud, and agent-building environment—but make the decision only after verifying that it can discover the agents your organization actually uses, assign accountable identities and owners, constrain tools and data access, and produce evidence your security team can act on. Microsoft Agent 365 and Entra, Google Cloud’s Gemini Enterprise Agent Platform, and AWS Bedrock AgentCore are conditional candidates for organizations centered on their respective ecosystems. The available product documentation describes vendor capabilities; it does not establish which platform is independently more secure.
What does an AI agent management platform need to manage?
The phrase can describe different things: a cross-agent governance control plane, a cloud-native agent platform with security controls, or an extension of existing identity and security tooling. These categories overlap, but they are not interchangeable. A runtime that executes an agent is not automatically an inventory of every agent in the organization; an identity feature is not, by itself, proof that every tool call is authorized or logged.
For a security team, evaluate the full control chain: discover agents and assign owners; authenticate agents and carry user context where needed; limit what they can access; govern their lifecycle; and retain audit evidence that supports investigation and response. A product label or feature list is not enough—ask the vendor to demonstrate the specific control in the configuration you plan to deploy.
How do the three platforms compare?
The table summarizes what each vendor’s documentation describes, not a third-party scorecard. Their scopes differ, so treat the rows as a shortlist and starting point for a proof of concept rather than as directly equivalent products.

| Platform | What its documentation describes | Most plausible starting point | Key validation questions | Price information in the reviewed pages |
|---|---|---|---|---|
| Microsoft Agent 365 and Entra | Agent 365 is described as a control plane with a registry, agent map, onboarding and integration management, lifecycle functions, audit and logging, and data, access, and threat controls. Entra documentation describes agent identities, discovery and metadata, Conditional Access and identity-risk signals, ownership, access reviews, lifecycle governance, and network controls for remote-tool activity and API or MCP access. | Organizations already centered on Microsoft identity, security, and data-governance administration. | Confirm licensing and rollout prerequisites, coverage for external agents and non-Microsoft runtimes, feature availability in the intended tenant and region, and event retention and export. | The Agent 365 page accessed for this article lists $15 per user per month, paid yearly, with an annual commitment. This is not a comparable total-cost figure; the reviewed Google and AWS pages do not state comparable prices. |
| Google Cloud Gemini Enterprise Agent Platform | Governance documentation describes Agent Identity, a central registry for agents, tools, MCP servers, and endpoints, policies, and Agent Gateway. It says identities use SPIFFE IDs and are secured by default with Context-Aware Access using mTLS and DPoP; it also describes relationship and traffic-flow views, semantic governance policies, and security and audit resources. | Teams building and operating agents in Google Cloud that want its documented registry, identity, and gateway controls. | Check component availability and maturity for the intended deployment, support for non-Google agents and endpoints, how policies are enforced, and integration with the existing identity system and SIEM. | Not stated in the reviewed Google Cloud governance page. |
| AWS Bedrock AgentCore and surrounding AWS controls | AWS guidance describes AgentCore Runtime as a managed execution option with security, scaling, session persistence, and isolation. It recommends identity propagation through agent chains, permission boundaries, audit trails, and circuit breakers, and names AgentCore Identity, gateway interceptors for MCP calls, Cedar-based AgentCore Policy, IAM and IAM Identity Center, Secrets Manager, CloudTrail, and EventBridge as supporting controls. | AWS-centered teams building or operating agents with Bedrock and existing AWS identity, logging, and cloud-security patterns. | Establish which controls are native and which must be composed, how delegated and user contexts are authorized, what events are logged and retained, and what the team must operate. | Not stated in the reviewed AWS guidance. |
Google Cloud’s page, last updated October 6, 2026, describes its suite this way: “Governance provides the framework for discovering, securing, and auditing AI agents and their underlying infrastructure at scale.” That is Google’s description of its product, not an independent assessment of its effectiveness.
Which platform should your team shortlist?
Choose Microsoft Agent 365 and Entra as a starting point when Microsoft is already central
Microsoft’s documented combination is relevant if the team wants to extend familiar Entra identity and Microsoft security administration to agents. Agent 365 describes least-privilege controls for users, data, tools, and MCP servers, alongside inventory, onboarding, lifecycle, audit, and security functions. Entra documentation adds identity blueprints and instances, authentication and action logs, ownership, access reviews, time-bounded access packages, and controls for remote-tool and API or MCP activity.
Rank #2
Do not assume this means all agents in a mixed estate will be discovered or governed. Demonstrate coverage for the organization’s actual external services, frameworks, and custom runtimes, and verify which functions are available under the exact tenant, license, and region.
Choose Google Cloud’s platform as a starting point when Google Cloud is the operational center
Google’s documented approach combines a registry, agent identity, policies, and a gateway. This may suit a team that wants agent governance integrated into Google Cloud operations, particularly when its agent workloads and cloud security processes are already there.

Documentation of a control does not establish that it covers every deployment pattern.
Choose AWS Bedrock AgentCore as a starting point when the team builds around AWS
AWS guidance presents AgentCore within a broader security architecture rather than as a standalone answer to every governance need. Runtime, identity, gateway interceptors, policy, IAM, secrets management, and logging can form a control set, but the team must understand how the pieces are configured and connected.
Rank #4
Ask the team responsible for the proof of concept to show the complete permission path across delegated work, including which identity makes each call and where a policy decision is enforced. Also establish which services and integrations the customer must configure and maintain.
What should you test before selecting a platform?
Run the same scenarios against each candidate using the agents, data, tools, and identity systems your organization actually uses. Record what the platform discovers, what it blocks, what it logs, and what work remains for your team.
Recommended Free Tools
- Inventory the real estate. Enumerate agents across internal build platforms, third-party services, and custom runtimes. For each one, record its owner, purpose, environment, data access, and tools. Ask the vendor to identify what it found, what it missed, and how discovery is performed.
- Trace identity through delegated work. Demonstrate a unique, attributable identity for an agent and trace a representative action through any chained or delegated agents. Confirm whether end-user identity or authorization context is carried forward, and how permissions can be reviewed and revoked.
- Attempt prohibited access. Try an unapproved tool, MCP server, API, data set, and outbound network destination. Verify that the intended control blocks each attempt and creates an event that an analyst can review. Identify any path that bypasses the gateway, interceptor, or policy layer.
- Exercise lifecycle and emergency controls. Test owner departure, an inactive agent, credential revocation, a suspected compromise, and emergency disablement. Confirm who can take each action, what access is removed, and what evidence records the change.
- Follow an action into incident response. Trace one representative action end to end: identity, relevant prompt or action, tool call, policy decision, and outcome. Confirm the event schema, retention, export or SIEM integration, and whether the evidence is sufficient for an investigation.
- Test data and human-approval scenarios. Use scenarios relevant to the team’s data-loss, prompt-injection, unsafe-output, and approval requirements. A successful vendor demonstration of one scenario does not establish broad effectiveness.
- Verify operational and contractual boundaries. Get written confirmation of license prerequisites, supported deployments, customer-operated components, telemetry paths, data-processing terms, region, retention, and the expected operating cost for the proposed configuration.
How to compare the controls that matter
Use these questions to make vendor demonstrations specific and comparable. Require evidence from the deployed configuration rather than relying only on feature names.
- Discovery and ownership: Which first-party, third-party, and internally built agents can it find? How often does discovery run? Can it map relationships and assign a responsible owner?
- Identity and authorization: Does every agent have an attributable identity? Can user identity propagate through delegated work? Can the team scope, review, and revoke permissions, and integrate with its existing identity controls?
- Tools and network: Can administrators allow or deny specific tools, MCP servers, APIs, and egress destinations? Can calls be inspected or blocked? Are denied calls and exceptions recorded?
- Lifecycle and governance: Can the team approve onboarding, assign owners, set expiry, disable orphaned or risky agents, and apply policy templates? Are changes themselves audited?
- Audit and incident response: Which identities, actions, tool calls, policy decisions, and outcomes appear in logs? Can those events be exported to the existing SIEM, and are retention and alerting adequate for the team’s needs?
- Data controls: How are sensitive data access, data movement, prompt injection, and output safety addressed? What regional processing and transfer details apply?
- Fit and operations: Which clouds, runtimes, frameworks, and endpoints are supported? Which components are managed by the vendor, and which add administrative or integration work for the customer?
- Cost and terms: What licenses, usage charges, prerequisites, and implementation effort apply? What written commitments govern telemetry, data processing, region, and retention?
How to interpret pricing and vendor claims
The Agent 365 price listed above is a page-specific figure accessed for this article: $15 per user per month, paid yearly, with an annual commitment. It should not be treated as a universal current quote or as the total cost of managing agents. The reviewed Google and AWS pages do not provide comparable prices, and the evidence does not establish a total-cost ranking. Reconfirm the current SKU, entitlement prerequisites, usage charges, and implementation costs directly for the proposed configuration.
All three candidates are supported here by vendor documentation and architecture guidance. Those sources describe intended features and designs; they do not independently establish security efficacy, comparative coverage, customer satisfaction, or hands-on performance. Availability, licensing, integrations, and terms can vary by deployment and change over time, so verify them for the specific edition, region, and contract under consideration.
