Next-Generation Threat Detection

Built differently from commercial ad-blockers.

Heuristic Analysis

We don't just rely on lists. Our Regex engine performs deep URL inspection to catch zero-day algorithmic tracking parameters like utm_source and invisible 1x1 pixels.

CNAME Uncloaking

Trackers hide behind fake first-party subdomains. Our engine taps into Firefox's native DNS resolution to unmask the true destination before the packet even leaves your browser.

Rust + WASM Core

Written in Rust and compiled to WebAssembly. Benefit from memory safety and O(1) HashSet lookups for near-native performance, even with 300,000+ threat rules.

Serverless Threat Intelligence

Data Privacy Guardian is backed by a fully autonomous, highly-available CI/CD pipeline.

  • Automated Aggregation: Python scripts run nightly via GitHub Actions.
  • Massive Scale: Aggregates over 300k+ known threats from global sources.
  • Zero Maintenance: The extension silently syncs the latest threat intel every 24 hours.
