PhishGuard — Link & Scam Defense

Browser-side risk checks for suspicious sites, links, and messages, with explanations that help you decide what to do next.

PhishGuard checks supported webpages for signs of phishing and scams and explains the evidence behind its warnings. WHAT IT CHECKS • Website addresses and links, including lookalike domains and known-threat matches. • Page structure, including sensitive forms and their destinations. • Signals associated with fake updates, tech-support scams, clipboard manipulation, and suspicious wallet requests. • Page text using a packaged local model. Suspicious wording alone does not establish that a page is malicious. HOW TO USE IT Open the PhishGuard toolbar popup to view the current page status and available controls. Read the explanation when a warning appears. On a blocked page, use the return button to leave. PRIVACY Ordinary page analysis runs in your browser. Threat-list downloads and site-icon requests can still use the network. Optional remote URL inspection is not configured in this release. REQUIREMENTS AND LIMITATIONS Requires desktop Chrome 138 or newer. Some browser pages and page content cannot be inspected. The text model is English-focused. PhishGuard can make mistakes and cannot guarantee that a webpage is safe or detect every scam.
