AI Access Security vs Glow: AI endpoint control facts side by side

Short answer

AI Access Security describes 1 of the four product control types on the pages we read and Glow describes 0; they differ on on-device control and network or SSE proxy. On decisions, AI Access Security does not describe tool-call decisions on the pages we read 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.

Positioning	Palo Alto Networks' control for employee use of GenAI apps, linked from its Prisma Access and SASE pages: visibility into shadow AI across 4,000+ GenAI applications, control over their use, and protection against sensitive data loss and malicious responses.	"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.
