Sui Validator Security Benchmark — September 2025

Abstract
This article summarizes NullRabbit’s September 2025 validator security dataset for the Sui ecosystem. The benchmark provides a transparent baseline of validator posture using a consolidated scoring model; it intentionally excludes vulnerability specifics (e.g., CVE lists) to avoid sensitive disclosures while still enabling comparison and improvement over time.

Methodology

• Publicly reachable validator endpoints were scanned using NullRabbit’s framework.
• Each validator received a 0–100 composite score derived from non-sensitive indicators of security posture and reliability.
• Data collected: 122 validators; 119 with valid scores.

Key Findings (September 2025)

• Score distribution ranged from 15 to 93.
• Median score: 45.
• 18.5% of validators met or exceeded the recommended “good practice” threshold of 70.

Validator Tools
Validators can query and rescan their scores through the NullRabbit Sentinel Discord Bot, and claim ownership for enhanced analytics.

Privacy & Safety
To promote responsible disclosure, NullRabbit publishes consolidated scores only in public datasets. Detailed findings, where applicable, are communicated privately with operators upon verification of ownership.

Conclusion
This benchmark is intended as a positive ecosystem health check. By publishing consolidated scores openly, NullRabbit supports validator communities in raising standards and strengthening decentralized networks. Monthly updates will provide ongoing visibility into improvements and trends.
