ARP Guard WiFi Security is an Android application developed by First Row, available for free in the Utilities & Tools category. This app is designed to provide security to personal data while using open WiFi networks. The app protects against network attacks, starting from ARP spoofing and ARP poisoning.

The app offers three modes - warning, invulnerability, and recovery. The warning mode notifies the user about any network attack, while invulnerability mode makes the device immune to attacks when superuser mode is available. Recovery mode helps to recover from an attack.

ARP Guard WiFi Security also has an auto-off feature that turns off WiFi when it detects an attack in non-root mode. The app notifies about the attack through vibration, sound, and a notice containing information about the attack.

Extra features are available for unlocking, such as permanent job functions that allow adding the app to the startup and prohibiting the system from unloading the app from memory. It also offers ad removal from the application.

Overall, ARP Guard WiFi Security is a comprehensive solution for WiFi security, providing protection against network attacks and ensuring the safety of personal data while using open WiFi networks.
