Free Windows app checks your home network with 101 security tests
An independent developer released a free Windows app that automatically runs 101 security checks on your home router and Wi-Fi. No technical knowledge needed — it finds problems and tells you what to fix.
Most home routers ship with default settings that can leave your network open to intruders. Checking them manually requires technical know-how that most people simply don't have.
This free app scans your home network and tests 101 things: open ports, router configuration, encryption type, connected devices, and more. It flags anything risky and explains the issue in plain terms. It runs directly on Windows and requires no special setup, making it a practical first step for anyone who wants to know if their home network is secure without hiring an expert.
Key points
- Free Windows app — no technical setup required
