🔴 Harmonic Security Raises $50 Million for Workforce AI Protection

Workforce AI security startup Harmonic Security today announced raising $50 million in a Series B funding round that brings the total raised by the company to $76 million.

Founded in 2023 by Alastair Paterson (CEO) and Bryan Woolgar-O’Neil (CTO), who previously founded Digital Shadows (acquired by ReliaQuest), Harmonic built a platform that secures AI tools for employees.

The solution covers browser-based AI, desktop AI tools, and agentic workflows to classify every AI task, identify its use, and provide real-time control over it.

Harmonic’s expanded coverage exposes risks such as personal-account use and sensitive data exposure, among others.
