What are the facts, side by side?
| Fact | Bay | Falcon Guardian |
|---|---|---|
| Owner | None | None |
| Positioning | An endpoint-first control layer for AI agents, coding assistants and MCP servers on employee devices. Bay describes itself as a fully preventive, agentless platform that classifies, governs and prevents risks across every AI agent and tool on enterprise endpoints. | 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. |
| How it reaches devices | Deploys through your existing EDR or MDM, with no new agents and no new tools; Bay says it scans in minutes and exits cleanly.

| On-device control | DescribedInventories AI agents, MCP servers, tools, credentials and extensions on the device, and its Enforcer returns Allow, Ask or Deny locally on prompts, pre-tool calls and post-tool responses on supported agent surfaces.

Where do they differ?
- Browser extension: Bay is not in our sources; Falcon Guardian partly describes it.
- AI or MCP gateway: Bay is not in our sources; Falcon Guardian partly describes it.
- Names the coding agents it covers: Bay matches; Falcon Guardian partly matches.
- Can warn or ask instead of only blocking: Bay matches; Falcon Guardian is not in our sources.
- Has a watch-only or simulation mode: Bay matches; Falcon Guardian is not in our sources.
- Also covers SaaS, cloud or homegrown AI: Bay is not in our sources; Falcon Guardian matches.
Choose Bay if
- Your developers run coding agents with many MCP servers and you want a decision on each action before it runs
- You want to add AI agent control through the EDR or MDM you already run instead of rolling out another agent
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
Which limits should you check?
Bay
- Endpoint only: no browser extension, network proxy or AI gateway is described, and nothing on SaaS or cloud-hosted AI apps.
- One of the smallest public footprints here: a single homepage, two blog posts, no documentation portal and no published pricing (re-checked 11 October 2026).
- Headline figures such as under 5 minutes to deploy, under 1% false positives and 100% of shadow AI discovered are Bay's own statements and have not been verified.
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.
