Enterprise VPNs have done a good job of securing corporate assets over the past couple of decades. But the landscape has changed. With a distrubuted workforce, assets are often no longer stored on-premise. As a result, most enterprise security teams are ready to evaluate new kinds of remote access solutions that align with their needs.

Zero Trust architecture

For many, the answer is going to be some kind of zero trust architecture. Organizations with a proponderance of remote workers or a completely mobile workforce are considering switching to either a CASB (if their resources are 100% in the cloud) or a software-defined perimeter (SDP) if they operate a mix of on-premise, private cloud and public web applications and data.

Direct insight from cyber security peers

In this report, created by NetMotion in July 2020, we surveyed 633 IT, network and security professionals from the US, UK and Australia to discover their views about VPNs and SDP adoption. Although 87% of organizations still use a VPN today, that number is expected to drop significantly by 2023 in favor of new technologies. 80% of these organizations are considering SDP as a viable alternative.

Walk away understanding:

  1. Remote access is the number one technology investment being considered by IT leaders as a result of the pandemic.
  2. 64% of IT and security leaders are dissatisfied with their visibility when remote workers use non-corporate networks.
  3. 97% of security leaders believe that remote workers are exposed to greater risk than their office counterparts.
