Privatus von Cristiano

Privatus is a professional-grade privacy and security extension that mitigates 138 attack vectors directly in your browser — no cloud, no telemetry, all local.

Tracker & Malware Blocking
Integrates 70+ blocklists (EasyList, uBlock, Hagezi, OISD, Disconnect, Brave, and more) using Bloom Filters for O(1) lookups at only 5.7 MB of memory. Blocks ads, trackers, malware, phishing, cryptominers, and scam sites.

Anti-Fingerprinting with Privacy Budget
W3C-compliant entropy tracking across 20 APIs (Canvas, WebGL, WebGPU, AudioContext, fonts, WebRTC, sensors). Configurable budget (4–32 bits/session) with automatic noise injection when exceeded.

DNS-over-HTTPS
Built-in support for Cloudflare, Quad9, NextDNS, AdGuard DNS, and Control D. Includes DNS leak detection and automatic fallback on high latency.

Password Breach Protection
HIBP k-anonymity: checks passwords using only the first 5 SHA-1 characters — your password never leaves your browser.

Certificate Transparency Monitoring
Real-time crt.sh monitoring detects unauthorized SSL certificate issuance for domains you visit.

SRI-Plus Supply Chain Integrity
Verifies SHA-256 hashes of 100+ popular CDN libraries (React, Vue, jQuery, Angular…) and alerts on mismatches or known CVEs.

Advanced Threat Detection
Detects Browser-in-Browser (BitB) attacks, WebCodecs exfiltration, Speculation Rules abuse, Import Maps hijacking, prototype pollution (Magecart patterns), and side-channel attacks (Spectre/cache timing/XS-Leaks).

Smart Context-Aware Profiles
Six profiles auto-select based on context: Normal, Strict, Paranoia, Banking, Developer, and Corporate. Includes per-domain whitelist and temporary 1-hour pause.

GDPR Compliant — Full User Rights
All data stored locally (no external servers). Supports data export, rectification, and complete deletion. Privacy by design (Article 25).

Multilingual
Available in English, Spanish, German, Arabic, Japanese, Russian, and Simplified Chinese.
