How do Bay and Neo compare on each criterion?
| Criterion | Weight | Bay | Neo | Edge |
|---|---|---|---|---|
| Visibility | 22% | 9 | 9 | Tie |
Why these scoresBay: Inventories AI agents, MCP servers, tools, credentials, extensions, settings and endpoint deployments, with 200+ detection rules (bay.io blog). Neo: Live inventory of agents, models, skills, MCP servers and extensions on every endpoint, with risk scores from its Neoverse knowledge base. | ||||
| Tool-call control | 20% | 9 | 8 | Bay |
Why these scoresBay: Evaluates prompts, pre-tool calls and post-tool responses and returns Allow, Ask or Deny locally, stated as under 4ms, on supported agent surfaces. Neo: Intercepts agent actions at the endpoint and allows, blocks or holds them for approval before they run. | ||||
| Policy | 15% | 9 | 8 | Bay |
Why these scoresBay: 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. Neo: Policies built with a built-in LLM, such as Block secret reads or Hold exports over 10 MB; actions are allow, block, redirect or hold for verified human approval, with an audit mode before enforcement. | ||||
| Identity and audit | 12% | 8 | 8 | Tie |
Why these scoresBay: Activity records who triggered an action, whether a human was involved, and the chain from prompt to system action. Neo: Ties every action to the human or agent that caused it, in what Neo calls an immutable audit chain, with alerts to a SIEM. | ||||
| Footprint | 13% | 9 | 6 | Bay |
Why these scoresBay: Deploys through existing EDR or MDM as an ephemeral binary (Wave); Bay describes itself as agentless. Neo: A lightweight endpoint sensor with no kernel module, no reboot and no OS hooks; analysis stays on the device. It is a new sensor rather than a rollout through existing EDR, and OS support is not listed on the pages we read. | ||||
| Breadth | 8% | 4 | 6 | Neo |
Why these scoresBay: Endpoint only by design; no public material on SaaS agents, cloud AI apps or red teaming. Neo: Its platform page names desktop and SaaS AI such as ChatGPT Desktop, Slack AI, Notion AI and Salesforce Agentforce alongside coding agents; cloud workloads and red teaming are not described. | ||||
| Maturity | 10% | 3 | 5 | Neo |
Why these scoresBay: Smallest public footprint of the scored tools: a single homepage, two blog posts, no public documentation portal and no published pricing. Neo: Came out of stealth on 20 July 2026 with $100M from Andreessen Horowitz and Bessemer; no documentation portal or pricing on neo.ai. | ||||
| Total | 100% | 7.9 | 7.5 | Bay |
How do they deploy, and what do they cost?
| Attribute | Bay | Neo |
|---|---|---|
| Owner | Not acquired | Not acquired |
| How it reaches devices | Through existing EDR or MDM (ephemeral binary) | Own endpoint sensor |
| Deployment detail | Bay 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. | A lightweight endpoint sensor with no kernel module, no reboot and no OS hooks; analysis stays on the device. It is a new sensor rather than a rollout through existing EDR, and OS support is not listed on the pages we read. |
