This document discusses how cloud computing, hybrid architectures, and agile IT delivery are transforming infrastructure and application delivery. It notes that traditional, static IT approaches are being replaced by more dynamic, automated approaches enabled by cloud, software-defined data centers, and DevOps practices. This brings challenges for security, which must also become more dynamic, automated, and integrated with development workflows. The document introduces CloudPassage Halo as a security platform designed for these new approaches, with capabilities like vulnerability monitoring, integrity monitoring, and policy-based controls that can scale across cloud and data center infrastructure.
