Bold Security

Bold Security is a cybersecurity company that develops an AI-based endpoint security platform designed to detect and prevent user-based threats directly on enterprise endpoints. The company's core product is an AI security agent that runs natively on endpoints, providing real-time visibility and protection across user actions, applications, files, and data flows. The platform addresses several security use cases: - Insider threat detection: Identifies suspicious or abnormal user behavior, whether accidental or malicious - Data loss prevention (DLP): Monitors and blocks sensitive data from being leaked through unauthorized channels, with in-the-moment user coaching - AI tool governance: Controls how data flows through AI applications regardless of the application, account, or data type - Forensic investigation: Provides full contextual evidence including data origin, transformation, and destination A key design principle of the platform is autonomous operation — the AI agent auto-discovers critical data, suggests and enforces policies, and classifies incidents without requiring manual rule-writing or policy tuning by security teams. The system is positioned as a lightweight agent that does not significantly impact end-user experience. Bold Security targets enterprise security teams and has disclosed customers including Shutterfly, Tekion, eCapital, Sunbit, Cresta, and HiBob. The company raised $40 million in funding and markets its platform as a replacement for legacy endpoint and DLP tools that generate high alert volumes with limited context. The platform operates entirely on the endpoint, which the company states eliminates cloud processing costs.
