How GuardRail Protects You

A hybrid approach that balances speed, accuracy, and privacy with intelligent local AI and cloud-based verification only when needed.

Local AI Detection

Machine learning models analyze URLs directly in your browser for instant protection against known threat patterns without sending data to the cloud.

Smart Cloud Verification

When local detection is uncertain, only the URL (never your browsing content) is checked against our threat intelligence network for a final verdict.

Complete Privacy

No browsing history stored, no user tracking, no content analysis. We only see URLs that need verification – nothing else.
