Guard DNS, Firewall, and Internet Guard are three Android apps designed to enhance your device's security and privacy by preventing unwanted data access and protecting your sensitive information.

Guard DNS is an app that allows you to block ads, trackers, and malicious websites by using a customizable DNS service. It's a great tool to protect your privacy and avoid online threats while browsing the web. With Guard DNS, you can choose from a variety of DNS servers and customize your filters to block specific types of content.

Firewall is another app that helps you protect your privacy and prevent unauthorized access to your device by blocking network traffic from unwanted apps. It's a powerful tool that lets you control which apps can access the Internet and which ones can't. You can set up rules to block specific apps or allow them to access the Internet only under certain conditions, such as when you're connected to a trusted Wi-Fi network.

Finally, Internet Guard is an app that lets you prevent other apps from connecting to the Internet altogether. This can be useful if you have sensitive information on your device that you don't want to share with third-party apps. With Internet Guard, you can easily block any app from accessing the Internet with just a few taps. You can also create exceptions for apps that you trust, such as your email or messaging app.

In summary, Guard DNS, Firewall, and Internet Guard are three powerful Android apps that can help you enhance your device's security and protect your privacy. Whether you're looking to block unwanted content, control which apps can access the Internet, or prevent unauthorized access to your device, these apps have you covered.

***Features***

App Firewall:
Prevent apps from connecting to the Internet.

A firewall blocks any app connecting to the Internet over Wifi or Mobile data. Since most forms of surveillance require the data to be sent the network to a server, firewalling them effectively mitigates the threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function).

Firewall feature uses Accessibility Service to detect and firewall background applications.

Monitoring:
Keep tabs on incoming and outgoing Internet traffic.

If enabled, the connectivity (DNS) logs are collected and analyzed. Automated reports flag previously unknown or suspicious connections, and reveal the extent of attempt to steal data by spyware networks. In our tests, around 60% of the traffic is flagged and reported as being initiated by known spyware. Logs generated are made available in near-real time to the user for their own analysis.Content Blocking:
Block spyware, malware and more.

Anti-Censorship:
The app encrypts your internet connection to Domain Name System (DNS) server run by Guard-DNS with presence in our 200+ locations world-wide. DNS servers are the address book of the internet: A DNS server provides the exact addresses you need to visit a website or open an app.

However, it is common to alter responses sent by DNS servers to block access or redirect to fake websites. By encrypting the connection to DNS servers on your Android device, Guard-DNS helps ensure that the results can’t be manipulated, so you can safely access the internet.
