Show HN: NetXDP – Kernel-Level DDoS Protection and Traffic Manager with eBPF/XDP

3 gaurav1086 0 7/21/2025, 1:53:56 AM

I built NetXDP, a lightweight, high-performance DDoS prevention and traffic management tool using eBPF/XDP. It dynamically drops bad traffic (malformed packets, port scans, floods) at the kernel/NIC level — before it hits your app.

Features include:

- Real-time packet inspection with dynamic greylist/blacklist - Custom rule manager with live server health dashboard - AI insights and detailed PDF reporting

Would love feedback from the HN community. Demo & details: https://youtu.be/l9-WGb4JlFQ
