CriterionWeightEntGlow SecurityEdge
Visibility22%78Glow Security
Why these scores

Ent: A live view of OpenAI Codex, Claude Code, Claude Cowork, GitHub Copilot, Cursor and other AI tools and agents; MCP server and credential inventory is not itemized.

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.

Tool-call control20%77Tie
Why these scores

Ent: Steps in at the moment of risk and blocks risky agent behavior; per-tool-call mechanics are not described on the pages we read.

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.

Policy15%87Ent
Why these scores

Ent: One programmable, intent-aware policy for people and AI agents, with responses from a soft nudge to a hard block, and app control that can allow, block, deny or restrict usage; an on-device small language model classifies sensitive data.

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

Identity and audit12%76Ent
Why these scores

Ent: Applies the same policy to people and agents and builds investigation timelines annotated in plain language as events happen.
