Brave is a privacy-focused browser founded by Brendan Eich, featuring built-in tools like a crypto wallet, VPN, and rewards system using BAT cryptocurrency. It offers robust privacy features through Brave Shields, which includes anti-tracking techniques such as ephemeral site storage to prevent cross-site tracking and a navigation-based approach to block tracking parameters and bounce tracking. Brave implements a strict-origin-when-cross-origin policy for referrer information and blocks the AMP framework to enhance user privacy. The browser also provides Private Windows with Tor for anonymous browsing and a subscription-based VPN for encrypted traffic. Brave's default search engine, Brave Search, is designed to protect user privacy by not storing browsing behavior for profiling. On the security front, Brave uses Google Safe Browsing, supports a strict HTTPS upgrade mode, and employs mechanisms like farbling to combat browser fingerprinting. Despite some criticisms, Brave maintains a dedicated user base in the privacy niche.
