How do CrowdStrike Falcon Guardian and Koi compare on each criterion?

Endpoint AI control score, editorial assessment 0-10. Edge is the higher score on each row.
CriterionWeightCrowdStrike Falcon GuardianKoiEdge
Visibility22%89Koi
Why these scores

CrowdStrike Falcon Guardian: Discovers shadow AI agents, including token consumption, on supported Windows, macOS and Linux endpoints, and ties prompts, skill use, tool calls and MCP servers to what runs next.

Koi: Visibility into models, MCPs, extensions and packages on the endpoint, with risk scoring.

Tool-call control20%87CrowdStrike Falcon Guardian
Why these scores

CrowdStrike Falcon Guardian: Connects to Claude Code's hook events to check and block prompts and tool activity as they happen, and returns allow or block before a Copilot Studio agent runs a tool.

Koi: Blocks unsafe AI application interactions and prevents prompt injections; tool-call level mechanics not published.

Policy15%67Koi
Why these scores

CrowdStrike Falcon Guardian: Sets which supported AI agent types may run on managed endpoints, with policy assigned through Falcon host groups; ask, warn or simulate actions are not described on the pages we read.

Koi: Out-of-the-box policies and one-click removal of insecure packages, extensions and AI tools.

Identity and audit12%85CrowdStrike Falcon Guardian
Why these scores

CrowdStrike Falcon Guardian: Ties Claude Code events to a specific session and user in Falcon Next-Gen SIEM, and links prompts and tool calls to identity and downstream execution for supported agents.

Koi: Agent vs human attribution not described on the pages we reviewed.

Footprint13%76CrowdStrike Falcon Guardian
Why these scores

CrowdStrike Falcon Guardian: Delivered through the Falcon sensor; Claude Code coverage is a settings-file entry with no extra agent to install. A third-party report (SACR) adds browser extensions, gateway integrations, an SDK and an MCP proxy, and says prompt-layer telemetry needs network connectivity.

Koi: Agent-based; offered as a Cortex XDR module and as a standalone offering.

Breadth8%97CrowdStrike Falcon Guardian
Why these scores

CrowdStrike Falcon Guardian: Covers AI agents from endpoint to cloud and SaaS, including Copilot Studio agents, with Falcon Adversary OverWatch threat hunting extended to AI agents; the AI gateway is listed as coming soon.

Koi: Palo Alto Networks is integrating Koi with Prisma AIRS for wider AI coverage.

Maturity10%87CrowdStrike Falcon Guardian
Why these scores

CrowdStrike Falcon Guardian: Part of the CrowdStrike Falcon platform, with a documentation site and earlier releases as Falcon AIDR; Falcon Guardian pricing is not on CrowdStrike's pricing page, and the 99% efficacy and 100 ms figures come from CrowdStrike's internal benchmark testing.

Koi: Acquisition completed 14 April 2026 by Palo Alto Networks; pricing not published.

Deployment detailDelivered through the Falcon sensor. Claude Code coverage is a settings-file entry with no extra agent to install. A third-party report (SACR) adds browser extensions, gateway integrations, an SDK and an MCP proxy, and says prompt-layer telemetry needs network connectivity. For Falcon customers it adds AI agent controls inside the EDR they already run.Integrates with Cortex XDR as a module and is also available standalone as an agent-based deployment. If you run Cortex XDR, this is the lowest-friction path; if you run another EDR, expect a separate agent.
