Netcraft Extension

Enhance your online safety with this browser extension, offering **robust real-time protection against a wide array of cyber threats, backed by a constantly updated global threat intelligence feed**. It actively defends you from phishing sites attempting to steal your credentials, fraudulent fake shops, and malicious JavaScript skimmers that secretly capture payment details. The extension also blocks intrusive cryptocurrency miners and helps prevent Cross-Site Scripting (XSS) attacks. A core principle is user privacy: the extension is designed so **the provider cannot know which specific web pages you individually visit**. While it collects hostnames of websites visited by its users for general website popularity ranking, it **explicitly avoids transmitting data from private internal networks** (like your home or work LAN). You maintain control with clear options to **disable analytics data sharing** and to opt-out of automatically reporting sites with malicious scripts. A key privacy safeguard is its **credential leak detection**, which blocks suspicious network requests if it detects sensitive data like credit card numbers or passwords being sent to an unexpected domain. You also gain insights into website trustworthiness through a **Risk Rating system** for new or unknown sites, helping you make informed browsing decisions. Available for Chrome, Firefox, Edge, and Opera.
