XDP Inline Defense for Validators: Kernel-Level Protection at Line Rate
•NullRabbit Labs•7 min read
Validator nodes face constant exposure. This deep dive explains how NullRabbit Guard uses eBPF and XDP to enforce security directly inside the NIC driver, dropping scans and abnormal traffic at line rate before they reach the kernel or your node.
Sui Validator Security Benchmark - September 2025
•Simon Morley•2 min read
NullRabbit's September 2025 benchmark provides a consolidated security snapshot of all Sui validators. Scores ranged from 15 to 93, with a median of 45, and 18.5% meeting our good practice threshold. This dataset and heatmap give validators tools to improve, while offering delegators transparency when choosing staking providers.
