Webroot Web Threat Shield is a URL reputation and anti-phishing extension that integrates with Webroot's WSA agent. It sends page URLs and HTML content through a local WebAssembly module for threat analysis. The extension has broad host permissions and passes full page HTML to the WASM layer, which is consistent with its stated phishing detection purpose. Minor issues: CSP uses wasm-unsafe-eval (required for WASM), and external message handling is restricted to Webroot's own block page domain.
