Glow Security review (2026): software control across the endpoint

The verdict

Glow Security positions itself as control over everything that runs on the endpoint, with asset intelligence, shadow AI discovery and an Anthropic integration that collects per-user Claude usage, custom skills and installed connectors. It describes a pre-execution hook that can block an action or hold it for approval, but how it reaches devices is not stated on its homepage and it does not publish pricing.
