Mobiles have spread completely into our personal and professional lives.

We are getting too much dependent on them. This will not be a danger unless we implement necessary measures for the safety of our privacy. Safety remains the need of the hour because we use most of the times public Wi-Fi or hotspots.

We take necessary measures like Anti-virus software, Encryption, multi-factor authentication and many others for our laptops. But we hear none about the security of Mobile devices.

To secure your personal data on phones, always avoid sharing sensitive data. Lock all the Apps with a password. Use unique passwords to lock different Apps.

Use a VPN.

And one of these security measures is using a Firewall.

What is a Firewall?


“A Firewall is used to protect (a network or system) from unauthorized access. It is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.”

Sometimes we have so many apps on our Android and are strapped for time. If you are free, you could access ‘Settings’ and just go to Data Usage to select ‘Restrict App Background Data.’

However, if you run the app, it will use internet data.

Moreover, there’s the problem of not being able to select apps individually or view network traffic and data usage statistics.

This is where Firewalls for Android come in. Android firewalls are significant for gaining more control over your phone’s communications with the Internet – blocking app Internet access, blocking IP addresses, controlling bandwidth, and so on.
