What Halborn does
Halborn is a Miami-headquartered (with New York presence), privately held blockchain and cybersecurity firm founded in 2019 that delivers professional security services to digital-asset and financial-services clients. The firm provides two main service categories: Advisory Solutions (AI Advisory, Blockchain Architecture Assessment, Compliance Readiness, Custody and Key Management Assessment, Risk Assessment, Technical Due Diligence, Technical Training) and Assurance Solutions (AI Security Assessment, AI Red Teaming, Smart Contract Assessment, Blockchain Layer 1 Assessment, Code Security Audit, Web/Cloud Penetration Testing, Red Team Exercises). Supporting these engagements are two proprietary tools: the Blockchain Vulnerability Scoring System (BVSS), a standardized vulnerability scoring framework, and Seraph, a policy enforcement tool that introduces centralized controls into decentralized applications and can simulate transactions on-chain.
The business operates on a custom, quote-based professional services model with multi-year contracts; pricing is not publicly disclosed, though industry context places top-tier smart-contract audit engagements at approximately $25,000 per engineer-week. Halborn's go-to-market is enterprise field sales with direct client engagement, supplemented by content marketing (blog, case studies, frameworks such as the stablecoin risk-rating whitepaper) and earned media coverage (Fortune, TechCrunch, CNBC, CoinDesk, Forbes, Bloomberg, CoinTelegraph). The company holds ISO 27001:2022, SOC 2 Type 2, and NIST CSF 2.0 alignment, and its 100+ practitioners carry elite credentials including CISSP, OSCP, OSCE, OSWE, OSEE, AWS, and CISA.
Halborn has completed 2,500-3,000+ security assessments, identified 13,000+ vulnerabilities, and claims protection of over $1 trillion in digital assets across 800+ clients. The customer base is concentrated in financial institutions (Sygnum, Bank Frick, AMINA, Banca Sella, Brevan Howard Digital, Grayscale), exchanges (Coinbase, OKX), major blockchain protocols (Solana, Stellar, Ripple/XRPL, Avalanche, Hedera, Rayls), stablecoin issuers (Circle/USDC), and government/sovereign clients (Banco Central Do Brasil, CBDC pilot). The firm last raised a $90 million growth round in July 2022 led by Summit Partners (with Brevan Howard, Castle Island Ventures, Digital Currency Group, SkyVision Capital, and Third Prime), and acquired Abyss in January 2022. Leadership comprises CEO Jacques Boschung, Co-Founder Steven Walbroehl, and Executive Chairman/President/Co-Founder Rob Behnke.
