CrowdStrike Falcon Guardian
by CrowdStrike
AI detection and response that finds shadow AI agents on the endpoint and blocks the unapproved ones
Falcon Guardian is CrowdStrike's AI detection and response (AIDR) product, announced at Fal.Con 2026, which inventories every AI agent running on managed Windows and macOS endpoints, blocks agents security teams have not approved, and traces an agent's actions from the user prompt through the tools it called. It is built for security teams whose developers have already deployed coding agents faster than governance could catch up.
CrowdStrike announced Falcon Guardian on September 1, 2026 at Fal.Con 2026 in Las Vegas, positioning it as the company's AI detection and response (AIDR) product and running it on the Falcon sensor already deployed across hundreds of millions of devices — no new agent to install. Its argument is architectural: the endpoint is where an AI agent actually reasons, plans and executes code, so it is the one place with a complete record of what the agent did. Guardian inventories known and shadow AI agents across Windows and macOS, running and dormant, records who deployed each one and its security posture, then lets administrators define which agents may run and blocks the rest. At runtime it reconstructs the full execution chain — user prompt, identity used, tools called, skills invoked, resulting system actions — and calculates blast radius when an agent is compromised or misbehaves. CrowdStrike's product page claims 99% detection efficacy against prompt attacks at under 100 milliseconds of added latency. Agent telemetry lands in Falcon Next-Gen SIEM as first-party data with retention included, correlatable against identity, cloud and SaaS activity. Several announced components were not shipped at launch: an AI Gateway applying Falcon policy to enterprise AI traffic including Model Context Protocol connections was pre-beta with GA targeted for the following quarter, and Falcon Complete for Guardian, the 24/7 managed tier, was due later in the quarter. CrowdStrike cites an 89% year-over-year rise in AI-enabled adversary attacks in its 2026 Global Threat Report as the driver.
A CISO or security operations lead already running CrowdStrike Falcon on the endpoint fleet, who has discovered that engineering teams deployed coding and desktop agents faster than security could inventory them.
A live inventory of every AI agent on managed endpoints — including shadow ones nobody registered — with the ability to block unapproved agents and reconstruct what a compromised one actually touched.

Key Features
- ✓AI agent discovery and inventory
Identifies known and shadow AI agents on Windows and macOS, both running and dormant, logging who deployed each one and its security status.
- ✓Agent access controls
Administrators define which AI agents are permitted to run on managed endpoints; anything not on the allowlist is blocked at execution.
- ✓Runtime execution-chain tracing
Links agent behaviour to endpoint telemetry, tracing from the user prompt through identity, tools and skills to the actions taken on the system.
- ✓Detection, response and blast radius
Detects attacks on agents and malicious agent behaviour, reconstructs what happened and scopes affected systems in real time to contain spread.
- ✓Native Next-Gen SIEM integration
Ingests AI agent telemetry as first-party data with retention included, correlatable against identity, cloud and SaaS events without a connector.
- ✓AI Gateway (announced, not GA at launch)
A central control point applying Falcon policy to enterprise AI traffic including Model Context Protocol connections; pre-beta at launch with GA targeted the following quarter.
- ✓Managed service tiers
Falcon Complete for Guardian adds 24/7 expert-led detection and response, and Adversary OverWatch adds cross-domain threat hunting for AI agent activity.
Capabilities
Use Cases
- •Shadow AI agent audit
A security team runs discovery across the managed fleet and finds coding and desktop agents that were never registered with IT or reviewed.
- •Blocking unapproved agents
After standardising on two approved coding agents, security allowlists them and Guardian blocks every other agent binary from executing on endpoints.
- •Compromised agent investigation
When an agent is manipulated by prompt injection, responders reconstruct the prompt-to-action chain and scope which systems and data it reached.
- •Enforcing AI usage policy
Governance rules about which AI services staff and applications may call become enforced controls at the endpoint rather than documentation nobody reads.
- •SOC correlation of agent activity
Analysts pivot from agent telemetry in Next-Gen SIEM to the identity, cloud and SaaS events around it during a single investigation.
Ideal For
Best For
- ✓Discovering shadow AI agents that developers deployed on managed laptops without security review
- ✓Enforcing an allowlist of approved AI agents on corporate Windows and macOS endpoints
- ✓Incident response on a compromised agent, where blast radius across tools and systems must be established quickly
- ✓Feeding AI agent telemetry into an existing Falcon Next-Gen SIEM deployment as first-party data
- ✓Turning a written AI governance policy into runtime controls that actually stop an agent mid-action
Not Ideal For
- ✗Organisations without an existing CrowdStrike Falcon deployment — the value depends on the sensor already being everywhere, and adopting Falcon solely for Guardian is a much larger commitment
- ✗Estates where agents run mainly on Linux servers or in containers rather than on managed laptops — discovery and inventory are documented for Windows and macOS
- ✗Buyers who need the full announced feature set today, since the AI Gateway was pre-beta at launch and Falcon Complete for Guardian had not shipped
- ✗Teams actively reducing vendor concentration, as NAND Research warns Guardian deepens dependence on a single vendor for an expanding set of security functions
Integrations
Deployment
Market Analysis
Pros
- ✓No new sensor required — it extends the Falcon agent already running across hundreds of millions of devices, which NAND Research calls its clearest advantage
- ✓Endpoint-level vantage point links AI agent behaviour directly to telemetry CrowdStrike already collects at scale, giving reconstruction depth network-first tools lack
- ✓Agent data lands in Falcon Next-Gen SIEM as first-party data with retention included, and CrowdStrike notes several competitors ship no SIEM of their own
- ✓Consolidates AI agent monitoring into the console security teams already use rather than adding a separate tool and separate queue
Cons
- ✗Announced as an incomplete product — NAND Research notes three components were unavailable at launch (AI Gateway, Falcon Complete for Guardian, cross-domain OverWatch), so near-term value depends on features not yet shipped
- ✗No pricing, packaging or general-availability date disclosed at announcement
- ✗Efficacy claims including 99% prompt-attack detection are vendor-stated; NAND Research explicitly conditions its assessment on whether they hold when independent security teams test them
- ✗Deepens single-vendor concentration for an expanding set of security functions, which NAND Research flags as a real risk for buyers managing vendor exposure
- ✗Discovery and access control are documented for Windows and macOS endpoints, leaving Linux server and container estates — where many production agents run — outside the described coverage

No list pricing was disclosed at announcement and none appears on the product page — Guardian is sold as a module on the Falcon platform, so real cost depends on the existing Falcon contract, endpoint count and which managed tiers are attached. A 15-day free trial is offered self-serve. NAND Research specifically flagged the absence of pricing and a GA date as a gap, and the managed tiers (Falcon Complete for Guardian) are separately priced add-ons rather than included capability.
