PhishGuard is a Chrome extension that aims to prevent email phishing attacks by providing link verification. With this extension, users can ensure they know what they're clicking on before accessing potentially harmful websites.

The main functionality of PhishGuard is to detect clickable links in emails and verify if the actual destination matches the advertised location. If the extension detects a discrepancy, it will highlight the link in red and bold, alerting the user to the potential phishing attempt. Additionally, when hovering over the link, PhishGuard will display the true destination, giving users the opportunity to make an informed decision before proceeding.

Currently, PhishGuard supports both Gmail and Outlook/Hotmail platforms, making it a versatile tool for users of these popular email services.
