Harmonic Security provides an AI Governance and Control (AIGC) platform that enables enterprises to adopt AI tools safely without risking data security and privacy. The company offers a 'zero-touch' data protection platform utilizing pre-trained, specialized large language models to detect sensitive data with high accuracy. Key offerings include Harmonic Protect, a data protection platform for secure AI adoption, and MCP Gateway, a developer-friendly gateway providing visibility and control over agentic AI ecosystems. The platform addresses 'Shadow AI' by offering continuous monitoring of unapproved AI tools, assessing associated risks, and allowing security teams to manage access and block sensitive content from being uploaded. Harmonic employs an end-user 'nudging' approach to guide safe AI usage alongside traditional security enforcement.
