Netcut Defender 2.1

Netcut Defender by arcai.com is a lightweight network security tool designed to protect your computer on shared local networks from ARP spoofing and “network cut” attacks. It continuously monitors your ARP table, locks your gateway, and automatically restores correct entries if tampering is detected, helping keep your internet connection stable and under your control. The app runs quietly in the background, can start with your system, and provides real-time alerts when suspicious activity occurs. Ideal for homes, dorms, offices, classrooms, and public Wi‑Fi, NetCut Defender helps prevent sudden disconnections and lag while giving you visibility into devices on your LAN. It requires little to no configuration and works alongside your existing firewall and antivirus.

Highlights:

• Real-time ARP spoofing detection and prevention
• Automatic protection and self-healing of ARP/gateway entries
• Low resource usage with optional start-on-boot
• One-click enable/disable and clear status indicators
