Derivation Chain

Step 1 Wi-Fi client isolation vulnerability disclosure (AirSnitch)
→
Step 2 Growing security concerns over Small Business customer Wi-Fi
→
Step 3 Non-expert Wi-Fi security self-diagnosis service

Problem

Small Business Owners running customer-facing Wi-Fi in cafes, restaurants, and accommodations face personal data breach incidents due to misconfigured client isolation, risking fines up to 40 million won (~$30,000) under privacy protection laws and reputational damage. Yet over 90% of Small Business Owners lack the technical knowledge to verify router security settings and operate with ISP default configurations.

Solution

A mobile web app that automatically audits client isolation, encryption strength, default password usage, and admin page exposure simply by connecting to the store's Wi-Fi. It delivers a plain-language Report with step-by-step remediation guides and sends periodic re-scan reminders to ensure ongoing compliance.

Target: Small Business Owners operating customer Wi-Fi in cafes, restaurants, and accommodations (1-5 employees); franchise headquarters IT managers
Revenue Model: Basic scan Free (once/month); Premium Monthly Subscription ~$11/mo (unlimited scans + periodic re-scan alerts + regulatory compliance badge). Franchise B2B ~$3.75/store/month
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
