About Bold Security

Bold Security makes endpoint software for data loss prevention, insider risk and control of AI tool usage.

AI models run locally on each laptop or desktop, so the agent can classify sensitive data, follow user and AI-tool activity, and enforce controls in real time without sending activity to the cloud for analysis.

The company presents it as a replacement for older endpoint DLP tools, and it says early customers saw up to 90 percent fewer alerts.

It sells to enterprises in financial services, insurance, software, healthcare and manufacturing, and names Shutterfly and Tekion as customers. Bold was founded in 2024, is based in Tel Aviv and came out of stealth in March 2026.
