Sherri Leach is a battle-tested cybersecurity executive and strategic leader with more than 30 years of experience protecting critical systems across government, defense, and global enterprise environments. She is the CEO of CyberCenturion, where she helps organizations strengthen cybersecurity strategy, manage risk, and build resilient security operations capable of staying ahead of an increasingly complex threat landscape.

Sherri’s career began in the U.S. Army, where she helped pioneer the Army’s first offensive information operations unit—developing cyber capabilities that supported national decision-makers and military commanders long before cyber warfare became part of everyday conversation. Since then, she has held senior cybersecurity leadership roles across industry and government, helping organizations navigate complex threat landscapes while protecting mission-critical systems.

Throughout her career, Sherri has led global cybersecurity operations for Fortune 500 companies, protecting billions of dollars in assets and tens of thousands of users. She is known for building elite cyber defense teams, advancing threat intelligence capabilities, and driving innovation through automation, AI-enabled security operations, and modern security architecture. Her work has helped organizations detect, respond to, and outpace sophisticated cyber threats while enabling business growth and transformation.

At her core, Sherri is a builder of teams, a solver of hard problems, and a defender of the digital frontier. When she’s not orchestrating cyber defense, she’s guided by the same principle that has shaped her journey from the Army to the executive suite: protect what matters most and stay one step ahead of the adversary.
