Harmonic Security lets teams adopt AI tools safely by protecting sensitive data in real time with minimal effort. It gives enterprises full control and stops leaks so that their teams can innovate confidently.   We are led by cybersecurity experts and backed by top investors including N47, Ten Eleven Ventures, and In-Q-Tel.   As AI adoption accelerates inside the enterprise, Harmonic’s ability to safely observe, control, and enforce policy at the endpoint is mission-critical.
