Modernizing Authentication — What It Takes to Transform Secure Access
Network Access Control (NAC) helps enterprises implement policies for controlling devices and user access to their networks. NAC can set policies for resource, role, device and location-based access and enforce security compliance with security and patch management policies, among other controls.

NAC is an effort to create order out of the chaos of connections from within and outside the organization. Personnel, customers, consultants, contractors and guests all need some level of access. In some cases, it is from within the campus and at other times access is remote. Adding to the complexity are bring your own device (BYOD) policies, the prevalence of smartphones and tablets, and the rise of the Internet of Things (IoT).
According to Gartner, the minimum capabilities of NAC are:
- Dedicated policy management to define and administer security configuration requirements, and specify the access control actions for compliant and noncompliant endpoints
- Ability to conduct a security state baseline for any endpoint attempting to connect and determine the suitable level of access
- Access control so you can block, quarantine or grant varying degrees of access.
- The ability to manage guest access
- A profiling engine to discover, identify and monitor endpoints
- Some method of easy integration with other security applications and components
