Neo vs Glow Security: AI agent security compared

Neo: Live inventory of agents, models, skills, MCP servers and extensions on every endpoint, with risk scores from its Neoverse knowledge base.

Glow Security: Positions itself as control over everything that runs on the endpoint, with Asset Intelligence and shadow AI discovery; its Anthropic integration collects per-user Claude usage, custom skills and installed connectors.

Neo: Intercepts agent actions at the endpoint and allows, blocks or holds them for approval before they run.

Glow Security: Glow describes a pre-execution hook that can block an action or hold it for approval, and runtime prevention policies for coding agents; per-call mechanics are not documented on pages we could read.

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.

Glow Security: Adaptable policies with autonomous remediation and prevention agents, and a Claude Code managed-settings bundle through its Anthropic integration.

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.

Glow Security: Per-user Claude usage and a compliance audit trail through the Anthropic integration, which needs Claude Enterprise and the Compliance API; attribution for other agents is not described.

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.

Glow Security: How Glow reaches devices is not stated on its homepage, and its documentation site could not be read.

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.

Glow Security: Covers software control and asset intelligence beyond AI tools, plus enterprise AI accounts and settings through the Anthropic integration; cloud workloads are not described.

Neo: Came out of stealth on 20 July 2026 with $100M from Andreessen Horowitz and Bessemer; no documentation portal or pricing on neo.ai.

Glow Security: Came out of stealth on 22 July 2026 with $180M at a $1.2B valuation, led by Sequoia, Cyberstarts, Greenoaks and Redpoint; named customer quotes and a trust center on glow.io; no pricing.
