Case Study: Halborn achieves phishing-resistant, scalable remote onboarding with Yubico YubiKeys

Leading blockchain security firm Halborn protects global, remote team with YubiKeys

Halborn is an award-winning, fully remote blockchain cybersecurity firm that has grown to over 100 employees across 50+ countries, serving blockchain projects, infrastructure providers and financial institutions. With crypto crime rising and sensitive client findings and zero‑day discoveries to protect, the company needed phishing‑resistant multi‑factor authentication beyond passwords and SMS to secure distributed access and maintain trust.

Halborn standardized on Yubico YubiKeys (YubiKey 5 Nano and 5C Nano) using FIDO2, issuing two keys per employee and integrating hardware MFA with G Suite SSO and layered access controls. The hardware keys made onboarding seamless at scale, enabled identity‑based access control and privileged four‑factor protections, and helped Halborn maintain a strong security posture — supporting rapid growth, regulatory best practices, and a record of protecting its own systems.
