A Rigorous and Collaborative Audit Process

Oak Security’s audit process is designed to be both rigorous and collaborative. Each audit is conducted by a team of at least three auditors who work independently to ensure a comprehensive review. The process includes static and manual code reviews, approved testing, and modeling methods. Findings are then discussed in a consensus meeting, resulting in a detailed report shared with the client.

This methodology ensures a 360-degree review of projects, maximizing coverage and depth. By employing diverse techniques and perspectives, Oak Security provides a thorough and nuanced understanding of potential vulnerabilities.

They provide individualized quotes based on the specific needs of each project, taking into account factors such as codebase size, complexity, and the specialized team required.

Frequently Asked Questions

Will an audit find all vulnerabilities? While Oak Security employs rigorous measures to identify critical issues, no audit can guarantee the discovery of all vulnerabilities. Security audits should be part of a comprehensive security strategy that includes secure design processes, extensive testing, and operational security practices.

How much does an audit cost? The cost of an audit is determined on a case-by-case basis, considering factors like codebase size and complexity. Clients can request a quote to get an estimated cost tailored to their project.

How is Oak Security different from other firms? Oak Security’s unique auditing process involves independent reviews by multiple auditors with domain-specific expertise, ensuring unbiased and comprehensive assessments.

How long does an audit take? The duration of an audit varies based on project complexity, ranging from 0.5 weeks for simple projects to 12 weeks for highly complex ones. Most audits typically take between 1 and 2 weeks.

When should a quote be requested? Early engagement is recommended to avoid delays. Oak Security can provide estimates based on work-in-progress versions of codebases and offers blanket reservations for projects not yet finalized.


Oak Security stands as a beacon of trust and reliability in the blockchain security landscape. Their comprehensive, methodical approach to security audits and advisory services ensures that clients can confidently navigate the complexities of decentralized technologies. By prioritizing transparency, expertise, and thoroughness, Oak Security is paving the way for a more secure and resilient decentralized future.
