About Johnathan Rozier

With over nine years of experience spanning cybersecurity, cloud security engineering, risk management, and program/project leadership, I specialize in strengthening mission-critical systems and delivering measurable improvements in cyber resilience across defense, federal, and financial sectors. As a Cyber Cloud Integrator at LMI, I direct multicloud security engineering and governance across AWS, Azure, and GCP, validating 950+ IL4/IL6 controls and integrating Zero Trust, NIST RMF, STIG, ISO 27001, COBIT, and FedRAMP requirements. Through direct technical contributions and team leadership, I reduced critical/high vulnerabilities by 48%, shortened ATO/IATT timelines by 37%, and improved audit readiness and evidence quality by 89% across enterprise programs.My impact extends across multiple organizations:• InComm Payments: Architected enterprise security programs that cut monthly security incidents by 48% and reduced vulnerabilities by 33%.• General Electric Credit Union: Built a secure Azure environment and automated vulnerability management, achieving an 80% reduction in critical/high vulnerabilities in six months.• U.S. Army Cyber Electromagnetic Warfare Officer 17B: Led cyber and EW initiatives for exercises with 3,500+ soldiers, integrated EMS effects into joint missions, and increased readiness by 40%.• Fifth Third Bank: managed enterprise patching across Linux and Windows platforms, reducing integration issues by 40% and deployment vulnerabilities by 70%. I operate at the intersection of cybersecurity, cloud engineering, mission operations, and modernization, designing secure architectures, guiding complex transformations, and enabling organizations to anticipate, withstand, and counter evolving threats. I remain committed to continuous learning and protecting what matters most to the nation, organizations, and the customers who rely on secure and available systems. Always open to connecting on cybersecurity, cloud strategy, AI/Zero Trust integration, and mission-driven technical challenges.
