ProbeShield WiFi Security Scan

Discover every device on your WiFi network, scan for open ports, and get a clear, AI-explained risk picture — all without creating an account or sending a single byte to the cloud. ProbeShield is a network security auditor built for people who aren't network engineers. Point it at your home or small-office WiFi and it finds what's actually connected, what's exposed, and what to do about it — in plain English, not packet dumps. WHAT IT FINDS • Every device on your network — ARP, mDNS, and ping discovery catches devices your router's own client list misses • Open ports on each device, with the service behind them identified • Default or weak credentials on SSH, HTTP, FTP, Telnet, and login forms • A five-tier risk score (Critical / High / Medium / Low / Safe) per device, so you know what to fix first AI THAT EXPLAINS, NOT JUST LISTS After a scan, an on-device AI (Gemini Nano) summarizes your risk picture in plain language and reads it aloud if you want — no findings dumped on you with no context. Tap into any vulnerability for AI-written, step-by-step fix guidance. ONE-TAP FIXES Found UPnP exposing your network to the internet, or Telnet left open on a router? ProbeShield can attempt an automatic fix directly, with manual guidance if it can't. BUILT TO BE TRUSTED WITH YOUR NETWORK A security tool that phones home is a contradiction. ProbeShield: • Requires no account and no sign-up • Never sends scan results, device data, or network info to any server • Only download: public vulnerability (CVE) data from NIST, about weekly • Stores everything locally, encrypted where it matters (PIN/biometric app lock via Android Keystore) • Only scans the network you're connected to, and only when you tap Scan WHO IT'S FOR Home users who want to know what's actually on their WiFi. Landlords and property managers auditing shared networks. Small business owners without an IT department. Anyone who's ever wondered "wait, what IS that device on my network?" Requires Android 8.0 (Oreo) or higher.
