Home Wi-Fi Security Monitor with Unauthorized Device Alerts

The user's post, 'Could someone be stealing my internet?', taps into a common worry among home internet users about unauthorized Wi-Fi access, highlighting a clear niche market. Current router admin panels are often not user-friendly, creating an opportunity for a SaaS solution. A mobile app (iOS/Android) could tackle this by continuously scanning the user's home network.

It would use device fingerprinting to clearly identify connected devices with intuitive names (e.g., 'Living Room TV', 'Sarah’s iPhone') instead of raw MAC addresses, and send an instant alert to the user's phone when a new, unrecognized device connects. The app could also offer features like one-click device blocking and regular security checks on Wi-Fi password strength and encryption.

This would be a consumer-focused subscription service, potentially priced at $2.99-$5.99/month. The expected revenue is based on this model; providing peace of mind and simplified security management to a broad audience could lead to significant recurring revenue (for example, achieving 50,000 subscribers at an average of $4/month could generate approximately $2.4M ARR).
