Competitive comparison

Harmonic Security vs. Onyx Security

Compare broad AI discovery with task-level workforce intelligence and context-aware control.

Harmonic Security

Understand how employees use AI, then govern each interaction

Harmonic analyzes the prompts, files, responses, and agent actions that make up workforce AI use. It interprets intent and sensitive-data context across supported browser, endpoint, and agentic surfaces.

Security teams can see the tasks employees are completing and the business use cases behind them. Harmonic uses this understanding to deliver precise warnings, nudges, and blocks while work is happening.

Onyx Security

Discover AI tools and agents across the enterprise

Onyx leverages its integrations and sensors to create an inventory of AI in use and provides a limited set of policy-based controls.

Visibility and control depth vary by surface. Onyx can enforce directly through supported sensor and gateway paths, while enforcement through third-party platforms depends on the actions exposed by each vendor’s API.

FAQ

Common questions

Why does task-level understanding matter when governing AI?

Knowing that an employee used an AI application does not explain what work they were doing or whether it created real risk. Harmonic groups related interactions into coherent tasks and maps them to organization-specific use cases while evaluating intent and sensitive-data context. This helps security teams understand risk, measure business value, and make informed decisions about AI tools and policies.

Why do context-aware controls matter?

Controls based only on the application or data type treat every interaction the same. Harmonic considers the user, application, data, intent, and action before intervening. This allows legitimate work to continue while warning, nudging, or blocking activity when the specific context creates risk.
