The defense industrial base remains one of the most critical—and most targeted—cyber risk environments in the world. In this session from ROCon Public Sector 2026, presented by Qualys in partnership with GovExec, Terrance Kalka, Director of DCISE at the Department of Defense Cyber Crime Center (DC3), joins Richard Seiersen, Chief Risk Tech Officer at Qualys, for a conversation on cybersecurity risk across the defense supply chain. From ransomware and nation-state threats to CMMC readiness, third-party risk, software supply chain security, hyper-prioritization, and operational resilience, this discussion explores what it takes to secure an ecosystem where small supplier weaknesses can create outsized mission risk. As AI accelerates attack velocity and adversaries increasingly target edge infrastructure, visibility, collaboration, and continuous risk reduction are becoming essential for protecting the defense industrial base.
