Firewall AI offers you complete protection against hackers and espionage. Block attacks from the internet and protect yourself from unwanted access to the internet. Determine which apps can and cannot access the internet.

With powerful firewall technologies, secure filter lists, and Artificial Intelligence (AI), you comprehensively protect your privacy and are informed about what is being shared with the world.

It is a powerful firewall app for Android with an intuitive user interface.

You can see in real-time which apps are accessing which servers or wasting mobile data. You can even allow or deny individual connections to an app with simple filter rules.

Protectstar™ Firewall Android is based on the Linux firewall iptables to protect you from cyber-attacks. We have combined the firewall with artificial intelligence (AI) to surpass security.

It is based on the Deep Detective™ and Protectstar™ AI Cloud technologies, so the firewall fends off modern hacker attacks, espionage, trojans, and even security gaps.

Did you ever wonder why many apps that don't require internet access still need internet permissions?

Usually, advertisements are placed, or your sensitive data is sent to servers in China, Russia, or the USA without permission.

With the Firewall AI app, you monitor and block this data traffic. You can completely prevent online access to an app. This also improves the performance of your device and relieves battery usage.

Wouldn't it be great if a firewall could do much more than protect against hacker attacks? The Protectstar™ Firewall AI was specially developed to block unwanted access by known intelligence services and government organizations.

With our integrated Intrusion Prevention System (IPS), all known servers and IP addresses from the FBI, CIA, NSA, GCHQ, and many more are automatically blocked.

Besides, you are protected from known spy servers in countries such as China, Iran, and Russia, as well as from spyware and mobile trackers. The anti-ransomware protection rounds off the security against modern ransomware.

Protectstar™ Firewall AI does not collect personal user data and is Ad-free, like all our apps.
