The Opera browser, developed by Opera Software, offers a variety of privacy and security features, including a built-in VPN, ad blocker, and malware protection, which aim to protect users from online threats like malware and phishing attacks. Despite these robust features, concerns over data transparency and security have persisted since Opera's acquisition by a Chinese consortium in 2016. The browser provides comprehensive tools for tracking protection, cookie management, password management, and private browsing, yet lacks built-in anti-fingerprinting measures, though these can be supplemented with extensions. Opera's security capabilities are enhanced by partnerships with security entities for phishing and malware protection, albeit not as effective as Google's Safe Browsing database. The browser's gamer-focused version, Opera GX, offers additional privacy features like the GX Cleaner and Fake My History, while Opera's overall transparency and VPN logging practices continue to be a concern for privacy-focused users.
