AI doesn't run in one place anymore. It runs in the browser tab, the desktop app, the agent your engineers kicked off, and the copilot embedded in the tools you already pay for. Harmonic Security governs all of it.

Our AI Governance and Control (AIGC) platform sits on the device, inside the interaction, at the moment of action, reading what AI is actually doing (not just the traffic around it) and acting in under 200ms. Security teams get full visibility and control across every AI surface, including the agentic and MCP layer that traditional tools can't see. Their people get to innovate without guardrails slowing them down.

We're gaining serious traction at the intersection of AI and cybersecurity, and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel. As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.

How We Work: AI-First by Design

Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively uses AI tools to do their best work, from research and writing to building automated workflows. We expect every new hire to bring genuine curiosity for AI and a commitment to working smarter and faster with it.

For some, this means staying open to new tools. For others, it means architecting new systems with AI at the core. We're transparent about expectations for every role, and we give you the tools and support to thrive.
