The strongest alternatives to evaluate are Microsoft 365’s native agent governance controls and Palo Alto Networks Prisma AIRS—but they address different needs, and neither should be treated as a feature-identical replacement for KnowBe4 Agent Risk Manager. Microsoft focuses on administration and lifecycle governance within its ecosystem; Prisma AIRS is positioned as a broader AI security platform with runtime protections. First decide whether you need agent inventory and ownership, administrative controls, or monitoring and enforcement of agent activity.
What does KnowBe4 Agent Risk Manager do?
KnowBe4 describes Agent Risk Manager as an enterprise layer for discovering AI agents, monitoring their interactions and tool executions, detecting risks, keeping audit trails, and helping teams investigate detections. Its product page names six detection categories: prompt injection, sensitive information, unbounded consumption, content safety, privilege escalation, and agent overstepping. These are KnowBe4’s descriptions, not independently validated performance findings. KnowBe4 Agent Risk Manager product page

Operational details warrant particular care: KnowBe4’s Quickstart Guide describes the product as being in technical preview and lists integrations for Anthropic Claude Compliance, Google Chrome, Google Gemini Enterprise, Microsoft Copilot Studio, Microsoft Edge, and OpenAI ChatGPT Compliance. Discovery and detections require a connected integration, and preview coverage may change. KnowBe4 Agent Risk Manager Quickstart Guide
There is also an important distinction around blocking. The product page describes response and blocking, but the Quickstart Guide says integration policies—including blocking unwanted activity—are coming soon. It separately documents browser-extension controls to approve, warn on, or block access to listed AI vendors. Confirm which controls are currently available for the specific integration and configuration under consideration rather than assuming general runtime blocking.
KnowBe4’s FAQ says its tool-execution analysis uses the user’s prompt, tool inputs, and surrounding conversation context. The company says processing runs on models hosted in its AWS infrastructure, sensitive information is masked before records are kept, and prompt content is not sent to third-party AI providers. These are vendor statements; review contractual terms for retention, access, processing location, and other requirements. The FAQ also describes Early Access eligibility limits, including direct customers on US instances with SAT Advanced subscriptions and community membership criteria; that does not establish general availability or pricing.

Which alternatives are worth evaluating?
Microsoft 365: native agent administration and lifecycle governance
Microsoft documents agent-management actions in the Microsoft 365 admin center, including installing or uninstalling agents, blocking or unblocking them, reviewing activation requests, and changing ownership. The effect of an action depends on the agent type: Microsoft documents different blocking scope for Copilot Studio agents than for SharePoint or Microsoft Foundry agents. This makes Microsoft’s controls a natural first option for organizations seeking administrative governance within Microsoft 365—not a guarantee of universal control over agents across every platform.

Rank #2
Microsoft’s Agent overview describes counts, usage trends, governance gaps, pending requests, ownerless agents, and visibility across supported Microsoft and connected platforms. Its summary card does not show every platform, and draft-agent visibility varies by platform. Treat it as a native inventory and governance view with defined coverage, not an exhaustive directory of every agent in an organization. Microsoft Learn: Agent overview in Microsoft 365 admin center
Palo Alto Networks Prisma AIRS: AI security and runtime controls
Palo Alto Networks positions Prisma AIRS as an AI security platform covering AI applications, models, and agents, with safeguards against risks such as prompt injection and data exposure. Its Agent Security page describes monitoring agent actions, verifying identity, and enforcing runtime policies. It is therefore relevant to buyers looking for AI security and runtime controls within a broader security platform. These are vendor descriptions; the available materials do not establish release status, integration coverage, deployment effort, or comparative effectiveness for a particular environment.

How do the options differ?
| Option | Primary emphasis in the available documentation | What to verify |
|---|---|---|
| KnowBe4 Agent Risk Manager | Monitoring agent interactions and tool executions, risk detections, and audit review. | Technical-preview status, connector coverage, enforcement availability, eligibility, and privacy terms. |
| Microsoft 365 native agent governance | Agent inventory, approvals, ownership, and lifecycle actions in supported parts of the Microsoft ecosystem. | Whether the agent types and platforms you use are visible and what each administrative action actually affects. |
| Palo Alto Networks Prisma AIRS | AI security across applications, models, and agents, including vendor-described runtime protections. | Current availability, integrations, deployment requirements, and whether its controls meet your policies. |
The table reflects vendor documentation, not a hands-on comparison. The right choice depends on the systems in use and the control gap to close; there is no supported basis here for naming a universal winner.
How to choose an AI agent governance tool
Write down the control you need before comparing product names. “Governance” can mean finding agents and assigning owners, approving activation, changing an agent’s lifecycle state, inspecting prompts and tool calls, or blocking risky activity at runtime. Those functions can belong to different layers, so a product that is strong in one should not be assumed to cover the others.
- Coverage and discovery: Identify the agent types and providers that must be inventoried, and ask what remains outside the product’s visibility.
- Governance layer: Specify whether you need approvals, lifecycle administration, identity and ownership, interaction monitoring, or a combination.
- Enforcement: Ask what can be blocked today, for which integrations, and under what configuration or policy conditions. Distinguish a documented capability from a roadmap statement.
- Auditability: Confirm which events and context are recorded, who can review them, and how long records are retained.
- Privacy and data handling: Establish what prompts, tool inputs, and conversation context are processed, where processing occurs, and which contractual controls apply.
- Deployment fit: Check whether the design depends on an existing Microsoft or Palo Alto environment, a browser extension, a vendor connector, a gateway, or other infrastructure.
- Availability and cost: Confirm regional and subscription eligibility, release status, and price directly with the vendor. Pricing is not established in the cited materials.
For a Microsoft-centered organization seeking administrative control, begin with Microsoft’s documented agent actions and overview, then check coverage for each agent type. For a team prioritizing runtime AI security across a broader application and agent landscape, assess Prisma AIRS against its actual integrations and deployment requirements. If evaluating KnowBe4, confirm the current preview access, connectors, and enforcement behavior for the intended setup.

The cited sources are vendor product and technical documentation, not independent performance tests. They do not establish comparative detection accuracy, pricing, full regional availability, or the contractual terms applicable to a buyer. KnowBe4’s Chief Product Officer Greg Kras said the product focuses on agent outputs and actions to reduce shadow-IT and prompt-injection risks; that is the company’s stated intent, not evidence of independently measured effectiveness.
