CertiK is the leading Web3 security firm, trusted by thousands of blockchain projects, exchanges, and ecosystems for its unparalleled expertise in auditing, monitoring, and compliance. Founded by Yale and Columbia professors in 2017, CertiK has become the industry's most comprehensive security service provider—securing over $484 billion in market cap through audits and intelligence.

With offerings ranging from smart contract audits and penetration testing to Skynet on-chain monitoring, CertiK empowers Web3 builders with real-time protection, formal verification, and actionable insights. Its mission is to advance trust and transparency in the decentralized world through mathematically sound and AI-powered security solutions.

CertiK provides a full-stack security and compliance solution that spans every stage of the blockchain project lifecycle. From pre-launch audits to post-deployment monitoring and compliance, CertiK ensures the resilience, trustworthiness, and compliance of Web3 applications. At its core is the renowned Smart Contract Audit service, which combines manual code review with automated tools and formal verification—a mathematical process that proves the correctness of smart contract behavior.

A standout feature is Skynet, a real-time Web3 security analytics platform that monitors more than 17,000 projects across on-chain and off-chain vectors. Skynet analyzes metrics such as code security, operational resilience, governance, community trust, and more. It provides real-time alerts, leaderboards, wallet analysis, and market intelligence—allowing both builders and users to track risk and performance dynamically.

CertiK also offers penetration testing for exchanges, wallets, and dApps—simulating real-world cyberattacks to reveal weaknesses. Meanwhile, its SkyInsights platform delivers AML and risk compliance services by leveraging address labeling, behavior-based risk scoring, and transaction screening. This is especially valuable for VASPs, institutional clients, and protocols seeking robust regulatory compliance.

The newly launched SkyNode Services demonstrate CertiK's commitment to blockchain infrastructure. As validators across more than 20 networks, CertiK enhances network reliability and decentralization while offering tools for node performance monitoring, automated updates, and rapid disaster recovery. Over $1.2 billion in assets are currently staked with CertiK nodes.

Compared to other security providers like Hacken, SlowMist, and Quantstamp, CertiK stands out through its scale, formal verification capabilities, and integrated products that cover both application security and infrastructure trustworthiness. It’s not just an auditor—it’s a partner in building secure Web3 foundations.
