Relying on iptables for volumetric DDoS mitigation is an exercise in futility. At 20M PPS, kernel context switching will completely starve your CPU.

The modern enterprise standard is eBPF & XDP.

Our engineering blueprint covers:
✅ Kernel Bypass via xdp_drop
✅ Handling multi-queue NIC race conditions using LRU_PERCPU_HASH maps
✅ Why 100Gbps Bare Metal is required to prevent upstream null-routes
