Why is Zero Trust Network Access (ZTNA) replacing legacy VPN?

With 74% of CFOs intending to shift some employees to permanent remote work, 2021 priorities have reoriented to how to better enable a remote workforce. Zero Trust Network Access (ZTNA) is being positioned as the successor to legacy VPN and by 2023, 60% of enterprises will phase out most of their remote access VPNs in favor of ZTNA.


Legacy VPNs remain a popular remote access solution for many businesses, but they might not provide sufficient risk management and can be more difficult to manage given the complex nature of modern business environments.


Businesses need to be fast and efficient to be competitive, while also being flexible enough to utilize the latest applications, wherever they may be hosted. IT teams need a scalable solution that can be easily managed and doesn’t require hardware or software connectors to be deployed.


For workers to be productive they need to have the tools to overcome the challenges they encounter. This could mean using a personal smartphone instead of a corporate laptop or accessing applications via a cellular connection instead of Wi-Fi. Workers need a no-nonsense remote access solution that gives them a fast reliable connection to their applications.


ZTNA has piqued the interest of organizations seeking a more flexible alternative to VPN, offering more precise access and session control to applications located on-premises and in the cloud.


The Gartner Market Guide for ZTNA provides an analysis of how companies are making the transition away from legacy remote access technologies like VPN to more infrastructure that is capable of handling the lack of standardization associated with modern IT environments. ZTNA provides a normalized user experience for users, devices and applications, eliminating the distinction between being on and off the corporate network.
