## Summary

Bold Security’s CEO Nati Hazut explains that the shift of work from browsers to local devices has created new data‑exfiltration channels that traditional network‑based security tools miss. By running small language models directly on laptops and desktops, Bold can classify sensitive information in real time, coach users, redirect activity, or block risky actions across browsers, desktop apps, and AI agents.

Hazut says the endpoint‑first approach lets the system understand the context and intent behind data movements, reducing false positives that plague rule‑based DLP. The models are engineered to use about 20% of the compute resources of legacy non‑AI agents, keeping laptops responsive while providing latency‑free decisions. He notes that autonomous agents can act at machine speed, so security must operate equally fast, distinguishing between legitimate employee use and agent‑driven risks.

Looking ahead, Hazut predicts every device will become an intelligent security layer that continuously decides which humans and agents may interact with particular data, giving enterprises granular, real‑time control over AI‑driven workflows.

## Key points

- Bold Security runs small language models on devices to classify and block sensitive data in real time
- Endpoint‑first approach sees activity that network, CASB, and DSPM tools miss, including autonomous AI agents
- Models use about 20% of the compute of legacy non‑AI agents, keeping user experience smooth

## Why it matters

As AI tools move to local devices, traditional perimeter security can’t see data flows, so on‑device AI protection is crucial for preventing corporate data leaks.
