Horizon3, an AI-driven cybersecurity firm based in San Francisco, has successfully raised $250 million in Series E funding. This substantial investment aims to fuel the company's expansion of its AI-native cybersecurity platform across the globe. Following the successful round, Horizon3's valuation has surged to over $2 billion, more than tripling its previous $600 million valuation.
