What are the facts, side by side?

|---|---|---|
| Owner | None | Palo Alto Networks (acquisition completed 14 April 2026) |
| Positioning | CrowdStrike's AI agent security product, described on 1 September 2026 as the evolution of Falcon AI Detection and Response (AIDR). It discovers shadow AI agents, connects agent activity to endpoint telemetry, governs which AI agents may run, protects prompts and sensitive data, and stops threats at runtime with containment, from endpoint to cloud and SaaS. | Koi, now sold by Palo Alto Networks as Cortex Agentic Endpoint Security, gives visibility into models, MCPs and extensions on endpoints, removes insecure packages, extensions and AI tools in one click, and stops malicious actions. |
| How it reaches devices | Through the Falcon sensor on supported Windows, macOS and Linux endpoints; Claude Code coverage is a JSON block in the Claude Code settings file with no agent to install, assigned through Falcon host groups.

Choose Falcon Guardian if
- You already run CrowdStrike Falcon and want AI agent controls in the same console
- Your agents include Copilot Studio as well as Claude Code
Choose Koi if
- You already run Palo Alto Networks Cortex XDR
- You want to find and remove risky extensions and packages across the fleet
Which limits should you check?
Falcon Guardian
- Needs CrowdStrike Falcon for the device path.
- Claude Code is the only coding agent named on the pages we read.
- The AI gateway is listed as coming soon, and no price is published.
Koi
- Agent-based: it adds an agent unless you run it as a Cortex XDR module.
- Warn or ask actions and a record that separates a person from an agent are not described on the pages we read, and no pricing is published.
