ExtensionShield

ExtensionShield is a Chrome extension security scanner and governance platform that audits browser extensions, producing comprehensive, evidence-linked reports focusing on security, privacy, and governance. It operates in an open-source mode using SQLite, allowing scans of extensions from the Chrome Web Store or local files, with features such as manifest and permission reviews, SAST findings, entropy checks, and integration with VirusTotal for enhanced analysis. Notably, it offers a customizable scoring system to evaluate extensions across critical security and governance dimensions.
