Understand AI usage and apply intelligent controls
Harmonic Security
Harmonic Security uses its own sensors to read and classify each interaction, including its context and the human or agent intent.
Security teams can understand exactly how AI is used down to the task level, then use Harmonic’s intelligent controls to guide users and agents at the point of interaction wherever they use AI.
WitnessAI
WitnessAI integrates with existing network security infrastructure to monitor employee AI usage. It also provides network-based discovery of AI agents and the MCP servers and tools they reach.
This approach provides broad network-level oversight, but less detail about the task behind each interaction and less direct control at the employee’s point of use.

FAQ
Harmonic analyzes supported AI activity at the point of interaction within the tool where it occurs, across browser and endpoint surfaces. WitnessAI monitors AI use primarily through integrations with existing network security infrastructure.
Harmonic groups related interactions into coherent tasks and maps them to organization-specific use cases. WitnessAI categorizes individual prompts using high-level, pre-set category labels. Harmonic therefore provides a more detailed view of business demand, risk, and productivity.
Harmonic can inspect the content and intent of supported agent tool calls and apply granular controls. WitnessAI focuses on discovering agent connections and governing which MCP servers and tools can be reached.
