Bay vs Glow: AI endpoint control facts side by side
Short answer
Bay describes 1 of the four product control types on the pages we read and Glow describes 0; they differ on on-device control. On decisions, Bay decides on a tool call before it runs and Glow describes some control over tool calls. We do not score either; the right choice depends on the AI tools people use, your devices, your current stack and whether you block or guide.

What are the facts, side by side?
| Fact | Bay | Glow |
|---|---|---|
| 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. | "The Endpoint AI Company": control over everything that runs on the endpoint, in three areas (Asset Intelligence, Software Control, Safe AI Adoption), plus an Anthropic integration that collects per-user Claude usage, skills, connectors and a compliance audit trail. Came out of stealth on 22 July 2026 with $180M; Tel Aviv and Palo Alto. |
| 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: Bay describes it; Glow partly describes it.
- Names the coding agents it covers: Bay matches; Glow partly matches.
- Decides on a tool call before it runs: Bay matches; Glow partly matches.
- Rolls out through EDR or device management you run: Bay matches; Glow is not in our sources.
- Can warn or ask instead of only blocking: Bay matches; Glow partly 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 Glow if
- Your company runs Claude Enterprise and wants per-user usage and an audit trail
- You want software control on the endpoint alongside AI controls
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.
Glow
- How it reaches devices is not stated on the pages we could read.
- No price is published, and the homepage figures are Glow's own statements.
