Summary
Bold Security emerged from stealth on March 12, 2026, announcing a $40 million Series A funding round co-led by Bessemer Venture Partners, with additional backing from Picture Capital and Red Dot Capital Partners. The company focuses on enterprise endpoint security, specifically targeting the real-time monitoring and risk mitigation of user and AI tool activity on edge devices—a historically underprotected security surface.
The founding team comprises CEO Nati Hazut, Chief Product Officer Hadar Krasner, and Chief Technology Officer Omri Mallis, all seasoned cybersecurity entrepreneurs. Hazut's track record demonstrates significant exit experience: he previously founded Polyrize, a data security startup acquired by Varonis, whose core technology now underpins Varonis's cloud platform offering. He also founded SAM, whose technology currently secures over 500 million connected devices globally for major telecommunications providers including Verizon and Virgin Media. At 35 years old, this represents his third company venture.
Bold's market entry timing capitalizes on a strategic shift in enterprise security priorities. According to Hazut, "the endpoint was the industry's biggest blind spot" for years as the industry assumed cloud consolidation would resolve security gaps. However, the AI boom has fundamentally reversed that assumption by both creating significant new security vulnerabilities and simultaneously enabling edge-based solutions to address them. The company's approach uses edge AI to transform endpoints from passive subjects under security monitoring into active agents capable of real-time threat detection and response.
Despite stealth status, Bold has achieved substantial commercial traction, already serving Fortune 500 enterprises and other significant US clients including Shutterfly and Tekion. This rapid adoption before public launch underscores strong market demand for comprehensive endpoint protection solutions in an AI-augmented enterprise environment. The $40 million Series A positions the company to scale operations and expand its customer base within an increasingly critical security category.
