President, Level Up LLC (an AVIAN company); Former CIA Cyber & Digital Policy Leader

Garrett Melich is a national-security cyber leader with nearly twenty-four years at the Central Intelligence Agency before entering industry. At CIA he served in cyber and digital policy leadership and helped stand up the Directorate of Digital Innovation, integrating cyber operations, analytics, and mission IT for intelligence and interagency partners. His focus was turning policy into operational capability under real-world constraints, with outcomes that could be tested and inspected by mission leaders and oversight bodies.

After government service, Melich led intelligence-community business development at Leidos, guiding programs that joined secure engineering, data operations, and cyber missions across highly regulated environments. He is now President of Level Up LLC, an AVIAN company, where he advances mission-ready technology adoption for federal customers and critical infrastructure operators. His work emphasizes zero-trust architecture, cross-domain solutions, supply-chain assurance, and repeatable readiness exercises.

Melich is known for building coalitions that endure. He aligns acquisition, governance, and deployment so agencies and prime contractors can adopt new controls quickly without disrupting operations. He briefs senior principals on threat evolution, secure-by-design practices, and cryptographic transition planning with an eye toward post-quantum resilience. He brings the credibility of long service in the intelligence community and the pragmatism of a private-sector operator who delivers results.
