CS Wallet Guard is a free anti-phishing extension designed for the Chrome browser, aimed at safeguarding users from malicious websites. Its primary feature is the automatic detection of user-entered URLs, which filters and blocks access to phishing sites based on a customizable whitelist. This ensures that users are protected from inadvertently visiting dangerous sites while browsing the web. The extension is particularly beneficial for Web3 users, as it includes tailored interception of Web3 Permit operations, which can help prevent unauthorized access to crypto assets.

The customizable whitelist feature allows users to utilize an official list that covers over 90% of legitimate Web3 and commonly used Web2 sites. Additionally, users can create their own exclusive local whitelist for added security. This dual approach empowers users to tailor their browsing experience while enhancing protection against phishing attempts, making CS Wallet Guard a valuable tool for anyone concerned about online security.
