As organizations operate across cloud infrastructure, distributed endpoints, and complex supply chains, security has shifted from a collection of point solutions to a question of architecture, trust, and execution speed. This report examines how core areas of cybersecurity are evolving in response to that shift. Across authentication, endpoint security, software supply chain protection, network visibility, and human risk, it explores how defenders are adapting to adversaries that move faster, blend technical and social techniques, and exploit gaps between systems rather than weaknesses in any single control.
