Download the newest Gartner report that discusses the NAC market, which they see as mature. The report includes these key drivers considered by clients when implementing a NAC solution:
- Visibility into infrastructure-connected devices with the goal of implementing access policies. This includes commonly used devices (such as a workstation, laptop, printer, IP phone, IP camera, access points, and also IoT devices like OT devices, medical devices and building automation)
- Manage access for contractors, consultants and different kinds of visitors to maintain visibility and limit access only to resources required according to each profile
- Enable the implementation of a BYOD program, primarily wireless, to ensure that employees can use their equipment while maintaining a minimum of due diligence for access to corporate infrastructure
- Analyze compliance with a minimum security posture at the endpoint. For example, verify that the endpoint has EPP installed, and most critical security patches are installed
- Select NAC solutions that are optimized to the size of their IT infrastructure. The NAC market is mature, and some vendors specialize in large environments, whereas others focus on small and midmarket organizations.
- Implement NAC in multiple phases. Phase 1 typically provides network visibility. Phase 2 usually enables device and/or user authentication to the network. Phase 3 commonly allows more advanced policies, such as blocking noncompliant devices from the network, but is rarely being used by the majority of enterprises.
