Protection and Control
It is a powerful firewall app for Android with an intuitive user interface. The firewall is not only ready to use in a few seconds, but it also protects you from hacker attacks and notifies you when an app tries to send data to the internet.
You can see in real-time which apps are accessing which servers or wasting mobile data. With simple filter rules, you can even allow or deny individual connections to an app.
Fend off Cyberattacks with Artificial Intelligence
Protectstar™ Firewall Android is based on the Linux firewall iptables to protect you from cyber-attacks. To even surpass the security, we have combined the firewall with artificial intelligence.
Based on the artificial intelligence technologies such as Deep Detective™ and Protectstar™ AI Cloud, the Android Firewall fends off modern hacker attacks, malware, 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 Protectstar™ Firewall, you monitor and block this data traffic. With two clicks, you select the apps that should be blocked. You can completely prevent online access to an app. This also improves the performance of your device and relieves the 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 Android 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 does not collect any personal user data and is Ad-free, like all our apps.
