Cybercriminals are always looking for ways to compromise smartphones and remotely steal information. One of their conventional methods for doing so is to install apps with malicious code on their victims phones and use them to exfiltrate sensitive data. Android phones are especially vulnerable to this scheme because, as opposed to iPhone, its easier to install apps on them that havent been published on Google Play store and havent undergone professional vetting.

GlassWire is the best Android security app for monitoring the data usage of various apps installed on your phone in real time. The app lets you see a live graph of your apps data consumption and will alert you when a specific apps data usage spikes.

If youre a regular user of free Wi-Fi in public locations and malls, you should know that theyre riddled with security threats. If youre not wary, malicious actors can intercept your internet traffic and steal your data or alter it. One of the best methods to protect yourself against theft or manipulation of data is the use of Virtual Private Networks (VPN). A VPN encrypts all your internet traffic, making it undecipherable to eavesdroppers. There are a handful of decent free VPN apps available on Android.

For secure browsing, you can also use Orfox, the mobile version of Tor browser. Like its desktop counterpart, Orfox encrypts your browser traffic and deflects it across several nodes before sending it to its destination, protecting you against both local spies and mass surveillance.
