Why Organizations Secure AI Agents with Falcon Guardian

CrowdStrike's Falcon Guardian, launched September 1, 2026, has been deployed at hundreds of organizations across financial services, healthcare, manufacturing, retail, energy and the public sector to discover and monitor AI agents, tools and MCP servers. In early deployments, customers reported hundreds of AI interactions their existing controls had not recorded, more than 260 distinct AI services in use at a single organization, and confidential documents and customer records being shared with public AI chatbots. CrowdStrike said Falcon Guardian extends the Falcon platform's endpoint runtime security into the agentic layer, linking AI telemetry with endpoint telemetry so security teams can see what an agent was asked to do and what it actually did on the endpoint.

AI is changing from a tool that generates content into agents that reason, decide, and take autonomous action. Employees now use AI assistants in their browsers and desktop apps. Developers run coding agents that read files and execute commands on their machines. Business teams build agents and connect them to enterprise data through Model Context Protocol MCP servers. This shift from asking AI to tasking AI creates hard questions for security teams: Which AI agents are operating in the environment? Who deployed them? What can they access? What are they doing? Since CrowdStrike Falcon® Guardian launched on September 1, 2026, it has been deployed at hundreds of organizations around the world spanning financial services, healthcare, manufacturing, retail, energy, and the public sector. We asked what led them to Falcon Guardian; their answers fell into five themes listed below. 1. Visibility is the top priority For most organizations, the first challenge was visibility. Security leaders knew AI use was widespread but lacked a view of which agents and tools were in use, what data was going into prompts, and which tools were sanctioned versus shadow AI. Falcon Guardian discovers AI use across endpoint, cloud, and SaaS environments spanning agents, tools, MCP servers, and more. In early deployments, various organizations deploying Falcon Guardian reported: Hundreds of AI interactions their existing controls hadn't recorded Over 260 distinct AI services in use at a single organization Confidential documents and customer records being shared with public AI chatbots Every modern organization has a shadow AI challenge if they have not deployed an AI detection and response AIDR solution. With the discovery and visibility that Falcon Guardian provides, security teams can set policy based on how AI is used across their organization. How long does it take Falcon Guardian to achieve this visibility in an environment? Only a few minutes for customers who have already deployed the CrowdStrike Falcon® sensor and licensed Falcon Guardian. Multiple customers deployed Falcon Guardian live in their production environments while participating in workshops at Fal.Con 2026 in Las Vegas and saw visibility immediately during the workshop. Figure 1. Falcon Guardian’s honeycomb dashboard that gives teams an organizational view of agents deployed on endpoints 2. AI executes on the endpoint AI agents run on laptops, workstations, and servers. They act through the same processes, files, and user permissions that the Falcon platform already protects. Falcon Guardian extends the Falcon platform's runtime security into the agentic layer. It works through the Falcon sensor and console that organizations already use, and also leverages the Falcon browser extension. Many organizations told us this was the deciding factor: CrowdStrike’s endpoint strength where agents execute. Tools that rely on inspecting network traffic or discrete integrations with each agent via hooks can't connect an agent's AI activity to the system actions it triggers. Falcon Guardian links AI telemetry with endpoint telemetry so security teams can see what an agent was asked to do, what it actually did on the endpoint, and how those actions affected enterprise systems. In the words of one CISO, CrowdStrike is "uniquely positioned" because it is already on the endpoint. Figure 2.

Agents are the new insider threat Workforce AI adoption in the browser started this AI revolution. Now, AI agents are moving it forward quickly and independently in many cases, as evidenced by recent lab containment breaches where agents have escaped their sandbox and attacked other organizations. Organizations are adopting coding agents, desktop AI apps, and internally built agents faster than most security teams can inventory them. In one customer evaluation, Falcon Guardian discovered two internally built agents that the security operations team didn't know were running. Another organization used Falcon Guardian to gain visibility into MCP activity across its environment and detect risky data and instructions passing between agents and MCP servers. The security challenge of agentic misalignment is real and expanding with agent adoption. In one instance, the CrowdStrike Falcon® Adversary OverWatch threat hunting team observed an endpoint agent attempt to use public data-sharing websites as a "convenient and fast" method to share corporate IP files to fulfill its objective. Discovery is the first step. From there, security teams can decide which supported agent types are allowed to run, enforce runtime guardrails to align agents to governance policy, investigate agent activity in the Falcon console, and respond when an agent behaves in unexpected ways.

Falcon Guardian is proven in testing Organizations are evaluating AI security rigorously, often with test suites they build themselves. Falcon Guardian's detection draws on CrowdStrike's prompt injection taxonomy, which covers more than 200 techniques. In customer-run evaluations: A financial services firm measured 99% detection accuracy on prompt injection A global telecommunications company measured 95%+ average block rates across malicious prompt categories, with 98%+ multilingual coverage Beyond detection, Falcon Guardian helps keep sensitive data from reaching third-party models. Policies can detect, redact, or block personal and confidential information in supported AI interactions. Access and content controls can be applied by user, application, and other attributes. 5. Businesses are saying yes to AI The organizations adopting Falcon Guardian are expanding AI. Many are rolling out enterprise AI assistants, coding agents, or internally built agents. Their executives and boards want guardrails in place first. For these organizations, Falcon Guardian has become an essential part of the rollout plan. One organization made Falcon Guardian a requirement before deploying an AI assistant to more than 20,000 employees. Other customers needed to show how AI use is governed in response to requirements such as HIPAA, DORA, NIS2, and the EU AI Act. Because Falcon Guardian is part of the Falcon platform, organizations can add it to their existing CrowdStrike deployment. Its findings flow into CrowdStrike Falcon® Next-Gen SIEM, so AI activity can be investigated alongside endpoint, identity, SaaS, and cloud data. Secure AI Where It Executes These organizations faced different AI programs and different pressures, but they arrived at the same needs. They need to discover AI agents and understand where risk is concentrated. They need to connect AI activity with endpoint execution to investigate and stop AI threats. They want one platform for AI visibility, governance, runtime protection, and response, starting at the endpoint and extending across cloud and SaaS environments. Falcon Guardian helps organizations adopt AI securely and keep innovating with confidence.
