NAC Evolving As Enterprise Networks Expand Beyond Secure Walls

Published: 27 Jul 2018

The Frost & Sullivan report analyzes the global market for Network Access Control. The “traditional” focus of NAC has been Authentication, Authorization, and Accounting (AAA). At its core, NAC is all about enabling mobility and dynamic security. However, the enterprise network no longer sits within four secure walls. It extends to wherever employees and data travel. Mobility, digitization, and the IoT are changing the way we live and work. The result is that networks are expanding and resulting in increasing complexity of managing resources and disparate security solutions. NAC is evolving to have improved visibility and monitoring of network devices, more security features, orchestration with other security products such as Next-Generation Firewalls (NGFW), SIEM, Web Content Filters, etc. Today’s NAC security solutions must deliver profiling, policy enforcement, guest access, BYOD onboarding and more to offer IT-offload, enhanced threat protection and an improved user experience. Growth is driven by growth of IoT, Bring Your Own Device (BYOD), increasing mobility, and organizations migrating workloads to the cloud. there is strong exponential growth of the number and diversity of endpoint devices and diverse operating systems (OSs). The increasing level of malware and cyber attacks is also driving further NAC investments. Network visibility is critical. Every device on a network is a potential attack or reconnaissance point that must be discovered and secured. A major trend is the convergence of IT and Operational Technology (OT), wherein NAC is helping break down silos.
