Harmonic Security built an AI governance platform that sits at the device layer, making every AI interaction visible and governable in under 200ms — whether employees are using approved tools like ChatGPT, shadow apps like DeepSeek, or spinning up local MCP servers. Traditional security stacks see AI as just another SaaS URL, but Harmonic understands AI has moved to the desktop, inside embedded tools, and into agentic workflows with no centralised audit trail. Their platform detects shadow AI, prevents sensitive data exposures (like private credit terms or customer info), coaches employees inline with context-aware warnings, and gives CISOs visibility into which AI investments actually drive productivity. It's built for a world where every employee and every agent is an AI user — and security needs to keep pace without slowing anyone down.
