In the face of escalating cyber threats, a prominent energy company with over €28.6 billion in external revenue and a workforce exceeding 30,000 employees recognized the vulnerabilities inherent in traditional password-based systems. To enhance security and streamline user access, they implemented Windows Hello for Business (WHFB) across more than 15,000 devices. This transition to passwordless authentication led to an 80% adoption rate within six months, a 70% reduction in password-related security incidents, and a 40% faster authentication process, significantly improving both security posture and user experience.
