Secure a Remote Workforce by Killing the VPN

VPN served its purpose well, but Zero Trust Network Access (ZTNA) is now transforming the definition of remote access solutions.

When it was created, VPN was an answer to the IT architectures and business challenges of the time. Centralized data centers hosting enterprise applications needed to be used by employees when they were ‘off-site.’ These connections needed to be encrypted and had to work over any internet connection. And while they were able to handle these tasks for decades, the landscape that it serves has changed.

VPN wasn’t built to secure cloud applications. It wasn’t designed to be elastically scalable. And it was never intended to give complete visibility into user activity and traffic.

As this year’s tidal shift to remote work swept across the globe, the cracks in the veneer of VPN became gaping holes with real productivity and security risks to the business. As these gaps were exposed, Zero Trust Network Access (ZTNA) emerged as the best way to provide the same functionality of VPN but with a greatly improved security posture that can be applied consistently across modern IT ecosystems.

ZTNA (also sometimes referred to as “software-defined perimeter” or “SDP”) is a networking approach that enables enterprises to provide access to all the applications and services an employee needs regardless of their physical location. It does this by providing micro-segmented network access to individual applications instead of access to the wider corporate network. ZTNA bases all connectivity on a user’s identity and the context around a user’s request.

This tightening of access coupled with increased visibility, control, and integration with security applications leaves few excuses for IT administrations to remain with dated VPN technologies.

It is time to kill the VPN. It has served its purpose well, but just as the cloud transformed the way that applications and services were delivered, ZTNA is now transforming the definition of remote access solutions.
