Digital transformation is a double-edged sword. While it can increase worker productivity, improve customer service, and enhance product offerings it is often not an easy journey; IT teams become stretched as they prepare to deploy new applications and continue to support existing services. The deployment can be challenging for any number of reasons but it can be summarised as expensive and painful.

Zero Trust Network Access (ZTNA) is poised to be part of the next big wave of digital transformation projects Gartner predicted in their 2020 Market Guide; by 2023, 60% of enterprises will phase out most of their remote access virtual private networks (VPNs) in favor of ZTNA. Working from home policies are a major driver for ZTNA adoption, which has been accelerated by COVID-19.

Unlike many other transformational projects, ZTNA promises to be substantially easier to deploy. This is possible because unlike the remote access tools that it replaces, which are iterations on decades-old technology, ZTNA uses an entirely new architecture. ZTNA solutions set out to solve not only architectural security flaws but also user experience and administrator management issues.

Five reasons why migrating to ZTNA is simple:

  1. It scales on-demand: As an entirely cloud-based architecture, ZTNA can scale with the organization’s needs to new applications or with the number of users. This means that there is no need to scope appliances, size servers or decide which features will be used ahead of time. Instead, the ZTNA platform scales with use, giving IT teams flexibility with how it is deployed.
  2. There is no infrastructure to manage: Another benefit of being built entirely in the cloud is that there is very little operational overhead. There are no appliances, servers, or on-premise connectors required for ZTNA to function. For IT teams this means that there are no patches or updates to deploy, no load balancing configure or availability to monitor. ZTNA operates similarly to SaaS, providing a highly available, always up to date service for organizations to consume.
  3. Configuration is straightforward: Designed with modern technology ecosystems in mind, the process of setting up a ZTNA service or integrating with other tools is simple. Unlike legacy models which require IP addresses to be configured or internal network routing to be set up, there is no such complexity. Additionally, because ZTNA is designed with the cloud in mind, it supports access to both on-premise and cloud-hosted applications.
  4. ZTNA can operate in parallel: There is no need for a rip-and-replace project, ZTNA can be implemented alongside existing technologies and phased in smoothly. Disconnecting one service and moving to another overnight is a big headache for IT teams, and it creates many end-user issues as they learn how to use the new tool. Instead, applications and users can be migrated across to the ZTNA service as needed, allowing administrators, users with mobile devices or select applications, to be moved first.
  5. The client is easy to deploy: End-user enablement is often a time-consuming part of launching a new service. Setting up clients on devices, sending out user credentials and troubleshooting issues can consume a surprising amount of time. The principles of modern design are present in ZTNA clients, the interface and user journey are shaped to make use seamless. As a result, ZTNA deployment is low-touch and creates a positive user experience.
