About this app

Take back control of your Android. Firewall Security AI – No Root is an advanced no-root Android firewall and app blocker with built-in DNS privacy control. It shows which apps can access the internet, blocks trackers and spy servers, and stops unwanted connections in real-time with an on-device AI security engine.

Many apps and system services silently send data to analytics providers, ad networks or unknown servers in the background. Firewall Security AI gives you visibility: every connection attempt is logged with app, host and country so you can block it with a single tap and help prevent data leaks before they happen.

WHY THIS NO-ROOT FIREWALL
• No root required: install, enable the personal firewall VPN and protect your device in seconds.
• All filtering on-device: traffic is routed through a local VPN interface on your phone, not through remote VPN servers.
• Ad-free and privacy-focused: for users who want strong firewall, anti-spy and hacker protection without clutter or in-app ads.
• No account needed: use the app without registration; firewall rules and logs stay on your device.
• Android 15 compatible and optimized for modern phones and tablets.

KEY FEATURES
• AI firewall & Deep Detective™ – Analyzes network behavior in real-time and helps detect suspicious or unknown connections, trojans and spyware.
• App & internet blocker – Create per-app rules for Wi‑Fi, mobile data and roaming, or completely block selected apps from going online.
• Intrusion Prevention System (IPS) – Focuses on blocking known outbound threats by using advanced filter lists with millions of malicious, tracking and spy domains so suspicious connections from your apps are stopped before they leave your device.
• DNS privacy & control – Choose secure or custom DNS providers and use DNS-based blocking to reduce tracking, ads, phishing and simple censorship attempts – no root required.
• Powerful filter lists – Use cybersecurity-grade lists with over 10 million domains to reduce ads, tracking, malware and spy servers.
• Live connection log – See outbound connections in a clean log with app name, host, IP address, country and timestamps so you always know where your data is going.
• Live data counters – Monitor how much data each app is sending or receiving directly inside the firewall.
• App tags & quick filters – Color-coded tags show at a glance which apps are allowed or blocked.
• Quick Settings tile – Toggle the firewall with a single tap from the Android Quick Settings panel.

TRANSPARENCY AND CONTROL
Firewall Security AI inspects outgoing traffic via the official Android VPN interface before it reaches the network. This anti spy firewall app uses the Android VPN Service to route traffic to itself so that it can be filtered on-device instead of on a server. This lets you:

• Stop background connections from apps and services you do not trust.
• Limit social media or games to Wi‑Fi only, saving mobile data and roaming costs.
• Protect yourself on public hotspots by quickly blocking new or unknown apps.
• Understand which apps use the most network traffic and adjust rules in seconds.

PRIVACY-FOCUSED DESIGN
All decisions are made on your device. AI checks run locally, and the firewall tunnel stays on your phone instead of forwarding traffic to external VPN servers. Firewall Security AI is designed to fit into everyday use without slowing your device down, while still giving you the transparency and control usually reserved for power users.

Ratings and reviews

Excellent product in regards to what a firewall should do. I highly recommend utilizing a firewall on all portable devices that store so much personal information about our lives and how much we depend on them. 5 Stars and a feature request to include bluetooth monitoring into this product as well as NFC. Affordable as much as it is usefull. Thank you.

found the flaw in the system, we all forgot about adsl tone attacks, because 'we don't use it any more' but the codex chip still sits on the hardware and acts as a back door, need network filter for that stuff, your welcome if I get more good Intel I'll let you know.

It is working great I love it especially with the smart home app from Att I can eliminate the IP addresses that have been using our home Internet, running our data out in two weeks leaving us with nothing, considering that we only had one TV hooked up the entire time!!! And we just got upgraded to the high speed Internet also which is a bummer 😞 I unfortunately have a good hacker that keeps adjusting the settings on my phone and apps like no other.

What’s new

+ Adjusted filter list resource management
+ Various adjustments and bug fixes

Thank you for using the Firewall AI and for being part of the Protectstar community!
