Firewall Security AI - No Root vs F-Secure Mobile Security Usage & Stats

Stop hidden tracking and unwanted connections. Firewall Security AI - No Root is a no-root Android firewall (app firewall / internet blocker) with DNS privacy and on-device analysis. Block trackers and spy servers, see every outbound connection in real-time, and control which apps can go online - without rooting your phone. Many apps and even some system services connect quietly in the background to analytics, ad networks, telemetry endpoints, or unknown hosts. Firewall Security AI makes this transparent: each connection attempt is logged with the app name, host/domain, IP address, country, protocol and timestamp. If something looks wrong, block it with one tap. PER-APP INTERNET CONTROL • Allow or block Wi-Fi, cellular data and roaming per app • Make specific apps fully offline when they don't need network access • Quick rules like "Wi-Fi only" or "Always block" for faster setup • Quick Settings tile to toggle the firewall in one tap DNS PRIVACY + CUSTOM DNS DNS is often the entry point for tracking. Choose a secure DNS provider or set a custom DNS. With DNS-based blocking you can reduce tracking, ads and phishing. Combine DNS + per-app rules for stronger control - no root required. SMART BLOCKING (OUTBOUND) • AI Firewall & Deep Detective™ help you spot suspicious or unknown connection patterns • IPS focuses on blocking known outbound threats using advanced filter lists (10M+ domains covering malicious, tracking and spy targets) • Block trackers and unwanted destinations while keeping the apps you need CONNECTION LOG & INSIGHTS • Clear log with app, host/domain, IP, country and time • Data counters to identify "chatty" apps and unexpected traffic • Tags and quick filters so you can find what matters fast REAL-WORLD USE CASES • Public Wi-Fi: block new or unknown apps until you review their destinations • Travel: keep roaming strict and allow only essential apps • Social apps: reduce background tracking without uninstalling • Games/streaming: set "Wi-Fi only" to avoid unexpected cellular usage • Quick privacy check: install an app, see where it connects, then decide QUICK SETUP STRATEGY • Start strict: block apps you rarely use and allow only what you trust • Put social/video/games on "Wi-Fi only" to keep cellular usage predictable • Review the connection log once, then fine-tune rules in seconds ANDROID VPN SERVICE 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. Important: this is not a location-changing VPN. Android VPN is used as a technical interface for local traffic filtering. Android typically allows only one VPN at a time - switch if you use another VPN app. PRIVACY BY DESIGN No ads. No account required. Rules and logs stay on your device. Firewall Security AI focuses on visibility and control of outbound (device-to-internet) connections to help reduce unwanted data sharing. If an app stops working after blocking, simply allow it again or set it to "Wi-Fi only". COMPATIBILITY Works on modern Android devices and is Android 15 compatible. Uses the official Android VPN framework for local filtering - no root, no risky modifications.
