CertiK

CertiK is a blockchain and Web3 security company focused on assessing and monitoring decentralized applications, smart contracts and blockchain protocols. The company provides security auditing and technology designed to identify vulnerabilities before they can be exploited. Its services include smart contract audits, blockchain security assessments, penetration testing, formal verification and security monitoring. CertiK's Skynet platform provides security intelligence and monitoring for blockchain projects, helping teams track risk signals and security events across decentralized ecosystems. The company works with Web3 protocols, DeFi applications, exchanges and other digital asset organizations that need independent security analysis. Smart contract security is particularly important because vulnerabilities can result in irreversible transactions and financial losses once code is deployed on a public blockchain. CertiK combines automated analysis with security researchers and auditing processes to identify coding issues, access-control problems and other weaknesses. Its monitoring capabilities can provide ongoing visibility after a project launches, rather than limiting security to a one-time audit. CertiK has published extensive research and security intelligence related to blockchain incidents and emerging Web3 threats. Its role is primarily specialized security assurance for blockchain technology rather than conventional enterprise endpoint or network security.
