Alyssa Miller, Business Information Security Officer (BISO) for S&P Global, is the global executive leader for cyber security across the Ratings division, connecting corporate security objectives to business initiatives. She blends a unique mix of technical expertise and executive presence to bridge the gap that can often form between security practitioners and business leaders. Her goal is to change how security professionals of all levels work with our non-security partners throughout the business.

A life-long hacker, Alyssa has a passion for technology and security. She bought her first computer herself at age 12 and quickly learned techniques for hacking modem communications and software. Her serendipitous career journey began as a software developer which enabled her to pivot into security roles. Beginning as a penetration tester, her last 16 years have seen her grow as a security leader with experience across a variety of organizations. She regularly advocates for improved security practices and shares her research with business leaders and industry audiences through her international public speaking engagements, online content, and other media appearances.
