Harmonic Security provides an AI governance and control platform focused on monitoring and controlling how employees use generative AI tools (web-based AI apps, embedded AI features in SaaS, and emerging agentic workflows). The product is designed to detect AI usage across web-based and embedded tools, inspect the content being shared (prompts, pasted text, uploads), and apply inline controls (block/allow, user coaching, policy enforcement). The company positions this approach as an alternative to traditional DLP/CASB methods that rely on pattern-matching rules and per-domain controls.
