Halborn

Halborn was founded with the vision to bridge world-class cybersecurity with the fast-moving demands of blockchain and digital asset ecosystems. Headquartered remotely and staffed by experts from backgrounds ranging from ethical hacking to defense, the team brings multi-domain strength to every engagement. What makes Halborn stand out is its ability to merge traditional InfoSec standards with modern decentralized frameworks—offering security audits, red team simulations, API testing, mobile app reviews, and cloud infrastructure hardening.

Over the years, Halborn has conducted over 2,500 security assessments across 15+ platforms and languages. The firm is also the only CVE Numbering Authority in the Web3 space, enabling responsible vulnerability disclosure and advancing global cybersecurity standards. From rigorous smart contract audits in Solidity, Rust, and Move, to extensive red team exercises simulating real-world attacks, Halborn ensures resilience from every angle.

Its client roster spans industries—servicing decentralized finance protocols, NFT platforms, exchanges, custodians, Web3 gaming, and institutional financial players. Services are highly customized, offering everything from full-scope “Secure-by-Design” consulting to post-deployment testing and compliance reviews. Whether protecting a global asset manager or a DeFi protocol, Halborn’s approach is thorough, technical, and built on decades of real-world experience.

Halborn competes with firms such as CertiK, Hacken, and SlowMist. However, its combination of enterprise-grade practices, elite offensive engineering, and deep involvement in the security community—including featured work in Forbes, CoinDesk, and Bloomberg—positions it as a top-tier choice for blockchain security at scale.
