Comparing Software-Defined Perimeter (SDP) with Virtual Private Network (VPN)

Zero Trust Network Access (ZTNA) is the latest security model being pushed by vendors and analysts as the next step in cyberdefense. It is often coupled with calls to deprecate, replace or kill VPN, a technology that has been a mainstay of remote access infrastructure for over 30 years.

Gartner predicts that by 2023, 60% of enterprises will phase out most of their remote access virtual private networks (VPNs) in favor of ZTNA.

If SDP is being dubbed as the long-term successor to VPN, helping businesses to achieve ZTNA, then what are the primary differences between the two technologies?

In our whitepaper, we analyze SDP and VPN against three criteria:

  • strength of security
  • ease of management
  • end-user experience
