Understand AI usage and apply intelligent controls
Harmonic Security
Harmonic analyzes the content, context, and intent of each AI interaction across browser and endpoint surfaces. It groups related interactions into coherent tasks and maps those tasks into organization-specific use cases.
Security teams can then apply granular controls based on how AI is actually being used, while leadership gains a clearer view of adoption, productivity, risk, and tool demand.
Glow Security
Glow maps and inventories what’s running across the endpoint. It uses endpoint policies to remediate or prevent unapproved software and reduce software supply-chain risk.
This approach answers which tools and components are present or allowed to run. It does not provide the same understanding of what work is being done with AI or whether a particular interaction is appropriate.

FAQ
Glow focuses on discovering and controlling the software and AI components running on endpoints. Harmonic focuses on understanding and governing how employees and agents use AI across browser and endpoint surfaces, including the intent and context behind each interaction.
Software discovery can show that an application, plugin, or MCP component is present. Harmonic analyzes the interactions themselves and groups them into tasks and business use cases, showing what work is being performed and where risk or value is being created.
Yes. Glow can support endpoint software and component governance, while Harmonic provides interaction-level understanding and controls across browser and endpoint AI use. The products address different layers of the problem.
