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.

Protection and Control
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.

Fend off Cyberattacks with Artificial Intelligence
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.

Easily Block Apps
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.

High-Secure Android Firewall: Protection also from the FBI, CIA, NSA & Co.
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.

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

Updated: Firewall App does slow down other apps as it filters out the unwanted. Firewall stopped some apps from access to the wifi or network if you so choose. However, with that said, turning off wifi and network access may not stop all apps from still accessing them. As the developers stated, you can go in and manually turn off individual urls of a specific app. I think the app cost to much, but I did buy it. Cost $42.49 with tax.

I like this APP, it makes me feel protected at the ease of a switch. Although One thing I've noticed this app has to be turned off to log into certain sites. The question is in doing so aren't I leaving my phone more vulnerable to attachs? Making it easier or more accessible to more? Honestly I'm technically challenged so I may not understand all the processes. I have backup protection that allows me into my more secure Apps with the protection on. Between the two I feel fairly comfortable.

Ever wondered what your phone is up to? Well the answer is "spying" on you. Yes, you! Packed with block lists for bad actors, polished Ui and very clever technology, Protectstar firewall has got you! Its not, repeat, not a VPN. It uses the VPN pathway get around the need to root your device. Rooting is not recommended if you aren't technically adept. Otherwise root just becomes a security risk. Protectstar Firewall gives peace of mind especially when used with their other products! 10/10
