Network Access Control vs. Software-Defined Perimeter

Network Access Control Security Must Change

Network access control (NAC) is a security approach designed to restrict the availability of network resources to endpoint devices. However, NAC only works inside the perimeter and once users are verified they typically obtain wide-ranging network access. NAC is an old and static technology.

Goodbye NAC, Hello Software-Defined Perimeter

Overcome NAC limitations with a Software-Defined Perimeter (SDP) based approach that provides dynamic, fine-grained access control based on a person’s identity. By creating an individualized segment of one for each user, a SDP will:

  • Better secure access to enterprise, cloud and hybrid resources
  • Simplify network configuration
  • Reduce operational effort
  • Ensure consistent access policies across hybrid environments

Why a Software-Defined Perimeter

A Software-Defined Perimeter is a new network security model that dynamically creates one-to-one network connections between users and the data they access.

A Software-Defined Perimeter solution ensures that any individual attempting to access a given resource is authenticated prior to being granted access to any resource. All unauthorized resources are inaccessible and invisible to the user.

In today’s mobile world–where employees are increasingly outside the perimeter–NAC is failing.
