On-Device AI Endpoint Security That Stops User-Based Threats at the Source

Bold Security is a cybersecurity company building an endpoint protection platform for the AI era. Its core product is an AI security agent that runs natively on each device, analyzing user actions, applications, files, and data movement to detect and block threats at the source. By processing AI models locally on the endpoint rather than in the cloud, the platform aims to deliver context-aware protection while avoiding the cost and latency of cloud-based analysis.

The platform targets several enterprise security challenges, including insider threat detection, data loss prevention, governance of data flowing through AI tools, and forensic investigation. Bold emphasizes minimal setup, automatically discovering sensitive data and suggesting policies rather than requiring heavy manual configuration. The agent is designed to understand the intent and context behind user behavior, reducing alert noise and acting on detected risks quickly through automated response.

Bold positions its technology for large enterprises across industries such as financial services, insurance, healthcare and life sciences, enterprise software, and manufacturing, where organizations manage thousands of endpoints. The founding team, including CEO Nati Hazut, CPO Hadar Krasner, and CTO Omri Mallis, brings prior experience building endpoint agents and data security platforms for large organizations. The company is backed by investors including Bessemer Venture Partners, Picture Capital, and Red Dot Capital Partners.
