Oak Security

Oak Security is a premier Web3 cybersecurity firm founded in 2017, specializing in comprehensive security solutions for blockchain and decentralized applications. With over 600 completed engagements, Oak Security has established itself as a trusted partner for leading Web3 projects, offering a unique 'blinded' auditing approach that ensures maximum rigor and thoroughness.

Core Services

Oak Security delivers a comprehensive suite of security services designed specifically for the Web3 ecosystem. Their flagship offering is multi-expert security audits using their signature 'blinded' methodology, where multiple auditors independently review every line of code before consensus meetings. This redundant approach consistently finds more issues than competitors. The firm also provides penetration testing to identify infrastructure vulnerabilities, operational security training for both technical and non-technical teams, virtual CISO (vCISO) services for on-demand security leadership, security and economic advisory covering protocol lifecycle strategy and economic modeling, and technical due diligence for investors and ecosystem foundations.

Technical Specializations

The team of 50+ security researchers holds expertise across the entire Web3 technology stack, including EVM (Solidity), Solana, Cosmos (CosmWasm), Polkadot/Substrate (ink!), Stellar (Soroban), Rust, consensus protocols and light clients, virtual machines, cryptographic primitives, DeFi protocols, liquid staking/restaking, cross-chain bridges and sequencers, and off-chain infrastructure. This broad technical coverage enables Oak Security to audit virtually any Web3 component with deep domain expertise.

Key Strengths

Oak Security's defining characteristic is their blinded auditing process, which emphasizes redundancy by design. Each audit is conducted by multiple senior auditors working independently in parallel, using diverse methodologies and techniques. Only in the consensus meeting do auditors reveal their findings, preventing bias and ensuring comprehensive coverage. This approach has repeatedly led to Oak Security finding more issues than competitors, even when working on the same codebase simultaneously. The firm maintains a team of 50+ security researchers with Master's and PhDs in Computer Science, Cryptography, Economics, Engineering, and Finance, providing holistic analysis beyond just code review.
