Halborn, founded in 2019 and headquartered in Miami, provides full-stack blockchain security services — smart contract audits and penetration testing — for organizations building or adopting crypto/Web3 infrastructure, including traditional enterprises entering the space. The firm is staffed almost entirely by security professionals with adversarial, offensive-security backgrounds, giving it an attacker’s-eye view across the full blockchain stack rather than audit-only code review.
Halborn has raised through a Series A and built an unusually strong named client roster spanning both crypto-native companies and traditional enterprises, reflecting real, well-capitalized adoption. It operates within the established blockchain audit-firm category, where its differentiator is offensive-security pedigree rather than a fundamentally new service model.
