METHODOLOGY
Our Security Assessment Framework
A systematic, multi-layered approach to securing your blockchain infrastructure, designed to identify and remediate vulnerabilities before they can be exploited.
01
Architecture & Configuration Review
We audit your node's architecture, consensus configuration, peer connections, and RPC settings against industry best practices to eliminate misconfigurations that lead to downtime or attacks.
50+
Config Checks
OWASP
Standards
02
Penetration Testing
Simulated attacks on your node's external attack surface, including RPC endpoints, P2P ports, and validator keys, to identify real-world exploit paths.

Frequently Asked Questions
Common questions about our blockchain node security hardening and penetration testing services for CTOs and engineering leads.
We follow a four-phase methodology based on NIST and OWASP standards: 1) Discovery & Assessment (inventory, configuration review), 2) Hardening Implementation (OS-level, network, and application-layer controls), 3) Penetration Testing (simulated attacks on RPC, P2P, and consensus layers), and 4) Remediation & Reporting (detailed findings with CVSS scores and prioritized fixes). This process has secured nodes handling over $500M+ in TVL.
