L. Scott Parker is the Founder and Principal Consultant of Aerisq, a consultancy dedicated to helping public and private sector organizations understand and manage the cyber and physical risks posed by drones. Through Aerisq, Mr. Parker provides expert guidance on aerial risk assessments, develops defense-in-depth policies and response frameworks, and trains public safety and security professionals on the evolving UAS threat landscape.

Mr. Parker previously served as the Chief of UAS Security at the Cybersecurity and Infrastructure Security Agency (CISA), where he built and led the agency’s first UAS Security Program. He established the office’s mission, staffing, interagency partnerships, and national guidance products — positioning CISA as a leading federal voice on drone risk management for critical infrastructure. His achievements include drafting the congressional report required by the Preventing Emerging Threats Act (124n) outlining how the federal government can protect critical infrastructure and core 30 airports; delivering cybersecurity guidance for critical infrastructure operating Chinese-manufactured drones; sponsoring flight restrictions for national events and high-risk infrastructure; and leading federal, SLTT, and private-sector engagement to elevate national awareness of emerging UAS threats. His work shaped congressional actions, federal policy development, and sector-wide risk management practices.

Prior to CISA, Mr. Parker served 27 years in the U.S. Army, culminating as the Sergeant Major for the Special Operations Division at the Pentagon, where he advised senior leadership on sensitive special operations and hostage-recovery missions. He holds an MBA and a graduate certificate in Disaster and Emergency Management.
