Cybercrimes and hacking attacks are growing at a high-speed rate. But this fact is more applicable to personal computers and laptops. You can prevent attackers from entering your PC/laptop by a network security device known as the firewall. The firewall monitors the network and the incoming and outgoing network traffic of your computer. It also filters malicious files. Your firewall automatically blocks the content that is unsafe for your computer.
Nowadays, people use mobile phones more than computers and laptops. You may think of securing your smartphone or Android device as it may contain important files, banking apps, and other useful documents. But, the risk of viruses and malware, and other malicious files is relatively low in Android devices. There are no known viruses on Android to date. So, as long as you use trusted applications, there is no risk. Always install and use trusted apps from Google Play Store. Unknown or suspicious apps can leak your information and that’s why you should never install applications from an unknown website.
As of today, you need not compulsorily install a firewall application on your Android. In the near future, hackers may target malware and other threats on Android devices. Though it is not necessary that you run a firewall on your device, being safe is always good. If you wish to add a firewall application to your device, here are a few top picks listed for you.

Additional ways to safeguard your device
Here are a few tips and suggestions for you to be in the safe zone.
- If you use public Wi-Fi (Wi-Fi networks in a shopping mall, club, or hotel, etc.), your phone is visible to everyone on that network. In this way, you are vulnerable to an attack. Hackers or attackers can attack your Android device through the Wi-Fi network.
- Do not connect your Android device to open Wi-Fi networks. Even if you connect to the Wi-Fi network of a trusted store, we recommend that you use a VPN (Virtual Private Network). A VPN creates many security coatings for your connection. In this way, you can stay safe from attackers.
- Only install apps from trusted sites and application stores. Never install suspicious apps or apps from unknown websites.
- Regularly update your apps by checking and installing them as soon as possible. Keeping your apps updated makes your phone free from risk.
- Know about any software or application before you install it. Read and know about the developers of the app, the number of users, and the Play Store rating for that app. Also, go through the user reviews of an app before installing the application.
- Install good security software on your Android phone. This can block malicious apps even if you install them unknowingly.
