Enterprise technology has changed. Work habits have changed. And the network perimeter has dissolved.


Network security must change to keep up with enterprise technology and work habits. This is causing a fundamental shift in network security. The difference is:    

Network Access Control (NAC) Trusts Users Inherently

This trust model is designed to work inside the perimeter, yet Forrester says it is broken for four reasons:  

  • It's impossible to identify trusted interfaces
  • The mantra "trust but verify" is inadequate
  • Malicious insiders are often in positions of trust
  • Trust doesn't apply to packets 

Software-Defined Perimeter (SDP) Trusts No One

Abolishing the idea of a trusted network inside (or outside) the corporate perimeter.  

NAC was designed to work inside the perimeter – Build a perimeter around the internal network, verify who users say they are, and once in the door users gain full access to the network or at least a large portion of the network. But in this changing world, NAC falls short for seven reasons.  

In our eBook, How to Overcome NAC Limitations: Why a Software-Defined Perimeter delivers better network security for today’s enterprises, we discuss the reasons NAC solutions fail to protect your network and why a Software-Defined Perimeter overcomes these limitations.  

This eBook is for security, network, IT architect, operations, infrastructure and GRC professionals who want to protect access to physical, virtual and cloud-based IT systems.
