Human Security, a late-stage startup selling anti-bot and fraud detection tools, has raised $50 million in new growth funding led by WestCap.

The New York company said Goldman Sachs, ClearSky, NightDragon, and Vertex also took equity positions as it builds momentum for its Human Defense Platform, which currently verifies over 20 trillion digital interactions weekly.

Human Security said the new investment will drive the adoption of AI techniques and expand its capabilities in digital account protection and media security, particularly in combating click fraud and ensuring ad integrity for platforms, agencies, and brands.

The company said the funding will also support the company’s deeper engagement in the public sector, including election security initiatives.

Human Security’s products span Advertising Protection, Application Protection, and Account Protection, addressing threats like account takeover, credential stuffing, and malicious ad activity. 

The latest raise follows a hefty $100 million funding round in January 2022 that included a push by Human Security into new product categories.

Human Security sells technology capable of differentiating between bots and human transactions on the internet, protecting enterprises from fraudulent e-commerce activity. 

Human Security competes with the likes of PerimeterX, Shape Security and Kasada in the anti-fraud bot protection business.
