Bold Security, founded in 2024 by Nati Hazut (CEO), Hadar Krasner (CPO) and Omri Mallis (CTO) in Tel Aviv, runs AI models natively on the endpoint so each computer performs local, real-time security analysis instead of relying on cloud monitoring. The platform understands how users and AI tools operate, detects accidental and malicious insider threats, prevents sensitive data leakage through coaching, warnings or blocking, controls how data flows through AI tools, and provides full forensic context on data origin and movement. Bold claims zero-configuration deployment, no cloud infrastructure costs, 95% faster investigations and detection-to-action within 60 seconds. It serves financial services, insurance, enterprise software, healthcare and manufacturing, with customers including Shutterfly, Tekion, Cresta, eCapital, Sunbit and HiBob. The company raised a $28M Series A in 2025 (with Bessemer Venture Partners, Picture Capital and Red Dot Capital Partners) following a $12M seed led by Bessemer and Picture Capital, for $40M total funding.
