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

Endpoint AI control score, editorial assessment 0-10. Edge is the higher score on each row.
CriterionWeightBayCrowdStrike Falcon GuardianEdge
Visibility22%98Bay
Why these scores

Bay: Inventories AI agents, MCP servers, tools, credentials, extensions, settings and endpoint deployments, with 200+ detection rules (bay.io blog).

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.

Tool-call control20%98Bay
Why these scores

Bay: Evaluates prompts, pre-tool calls and post-tool responses and returns Allow, Ask or Deny locally, stated as under 4ms, on supported agent surfaces.

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.

Policy15%96Bay
Why these scores

Bay: Session-aware decisions using identity, prior actions and data accessed; capability rules for shell, code execution, package installs, cloud CLIs, containers, Kubernetes, browser automation; Simulation Mode.

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.

Identity and audit12%88Tie
Why these scores

Bay: Activity records who triggered an action, whether a human was involved, and the chain from prompt to system action.

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.

Footprint13%97Bay
Why these scores

Bay: Deploys through existing EDR or MDM as an ephemeral binary (Wave); Bay describes itself as agentless.

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.

Breadth8%49CrowdStrike Falcon Guardian
Why these scores

Bay: Endpoint only by design; no public material on SaaS agents, cloud AI apps or red teaming.

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.

Maturity10%38CrowdStrike Falcon Guardian
Why these scores

Bay: Smallest public footprint of the scored tools: a single homepage, two blog posts, no public documentation portal and no published pricing.

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.

How it reaches devicesThrough existing EDR or MDM (ephemeral binary)Falcon sensor; Claude Code via hooks
Deployment detailBay states that it deploys through your existing EDR or MDM using Wave, an ephemeral binary that runs, scans and exits. It describes the product as agentless by design, with no new agent or tool to install, and says full deployment takes under 5 minutes (vendor-stated). Enforcement then happens locally on the device. In practice this means Bay runs beside your EDR, not in place of it.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. For Falcon customers it adds AI agent controls inside the EDR they already run.
PricingContact sales. Bay does not publish pricing. Demo requests go through bay.io/demo.Contact sales. Falcon Guardian pricing is not on CrowdStrike's pricing page.
