RankShield Browser Guardian

Warns you about risky extensions, phishing & OAuth-consent traps, and known-bad sites — backed by a privacy-preserving threat mesh.

RankShield Browser Guardian is a privacy-first security extension that watches your back as you browse — and warns you the moment something looks wrong. WHAT IT DOES • Risky-extension audit — continuously checks every extension you have installed and flags the dangerous ones: over-permissioned, able to read & change data on all sites, sideloaded/unreviewed, or reported by the RankShield threat network. (Recent supply-chain attacks hijacked trusted extensions — this is your early warning.) • OAuth consent guard — when a site asks for high-risk access to your Google account (Gmail, Drive, long-lived "offline" tokens), Guardian warns you before you click Allow. These consent traps can bypass passwords and even MFA. • ClickFix / paste-hijack alert — flags the "copy this and paste it" trick used to take over accounts during sign-in. • Known-bad site blocking — blocks navigation to phishing and malware hosts from a live, federated threat feed. • Profile-compromise signals — watches for in-browser signs that your profile may be at risk (a changed signed-in account, a newly installed or sideloaded extension) and tells you what to do next. • Federated protection — one user's detection helps protect everyone, while only de-identified threat signals are ever shared. PRIVACY FIRST We never read or transmit your passwords, cookies, page content, or browsing history. The only thing that leaves your browser is a one-way fingerprint of a threat indicator — never anything that identifies you, the site, or your account. No ads. No selling data. No tracking. Privacy policy: https://rankshield.co/browser-guardian/privacy HONEST BY DESIGN Some attacks happen outside the browser (such as operating-system-level cookie theft), and no extension can stop those — so we don't pretend to. Guardian tells you exactly what it can detect, warn on, and block, and points you to the right next step (like turning on passkeys) for everything else. From RankShield — https://rankshield.co
