Protect and Control
Android Firewall is not only ready to use in seconds but also protects you from hacker attacks and notifies you when an app tries to send data to the Internet.
Get a real-time view of which apps are accessing which servers or wasting mobile data. With simple filter rules, you can even allow or deny certain connections of an app.
Easily Block Apps
Why do many apps that don't require Internet access still need Internet permissions? Usually, they either serve ads or send your sensitive data to servers in China, Russia, or the USA without permission.
With the firewall, you can monitor and block this data traffic. You can also completely block the online access of an app.
Protection from the FBI, CIA, NSA, and others
Wouldn't it be great if a firewall could do much more than protect against hacker attacks? For example, the AI Android firewall can block unwanted access from known intelligence agencies and government organizations. With our built-in Intrusion Prevention System (IPS), all known servers and IP addresses of the FBI, CIA, NSA, GCHQ, and many more are automatically blocked.
If there is an access attempt, you will receive a special warning. In addition, Firewall AI protects you from spy servers in countries like China, Iran, and Russia, as well as mobile trackers.
Change your DNS server
DNS servers give you additional protection, as they provide essential protection against surveillance and censorship attempts. With just one keystroke, Firewall AI finds the fastest DNS server and connects to it to speed up your network connections.
Parental control servers ensure safe web browsing for your family. Additionally, you can conveniently protect yourself from phishing, malware, ransomware, and malicious domains.
