Founding Story

Prior to CrowdStrike, Marston served as the President and Chief Operating Officer of AirDefense, a wireless security company that was acquired by IBM in 2007, and held senior leadership roles at Network Associates (later McAfee). Marston's expertise in building and scaling channel partner ecosystems was instrumental in developing CrowdStrike's 10,000-partner global reseller network, which now drives 70% of the company's new business.
