Protectstar™ Firewall Pro for Android is a next-generation firewall app that shields your device from hackers, spyware, ransomware, and unwanted internet access. Trusted by over 3 million users in 123 countries, it combines AI-powered security, Deep Detective™ technology, and an intrusion prevention system (IPS) to automatically block malicious servers, suspicious apps, and hidden background connections.
With just two taps, you can block any app from accessing the internet, improve performance, reduce battery drain, and protect your personal data from being sent to unknown servers in China, Russia, the US, or beyond. Unlike traditional firewalls, Protectstar™ is constantly updated with the latest AI rules to stop new threats instantly—just like modern cybersecurity used by intelligence agencies.
Perfectly designed for Android 5.0 and above, it works seamlessly alongside other security apps like Camera Guard, Anti Spy Professional, and Micro Guard, ensuring complete privacy without ever collecting your personal information.
