Halborn is a blockchain and digital-asset cybersecurity firm that sells professional security services rather than a developer product. Its assurance practice covers smart contract assessments, Layer 1 protocol reviews, code security audits, web application and cloud infrastructure penetration testing, red team exercises, and custody and key management assessments; its advisory practice covers AI security, blockchain architecture, compliance readiness, risk assessment, technical due diligence and technical training for banks, exchanges, custodians, tokenization platforms, stablecoin issuers, DeFi protocols, central banks and blockchain infrastructure providers. Halborn publishes its engagement results as a public audit repository, discloses zero-day findings under its own CVE assignment scope as a CVE Numbering Authority, and maintains BVSS, the Blockchain Vulnerability Scoring System. As of August 2026 it publishes no public API, no developer portal and no machine-readable contract; its Halborn ONE client platform at one.halborn.com is an invitation-only customer portal.
