What are the facts, side by side?
| Fact | Falcon Guardian | Zscaler |
|---|---|---|
| Owner | None | None |
| 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. | Zscaler's controls for employee use of generative AI: prompt-level visibility, allow or block by app, DLP blocking across GenAI apps, browser isolation that disables cut, paste and download, and data security for Microsoft Copilot. |
| 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 Zscaler if
- You already route traffic through Zscaler and want GenAI controls there
- Your main risk is sensitive data pasted or uploaded into GenAI web apps
