Market Guide for Zero Trust Network Access

A Market Guide for Zero Trust Network Access

With the rise of IoT and mobile computing, ZTNA is becoming a necessity. In this article, a market guide for Zero Trust Network Access will be given. Read on to learn more.


The Zero Trust Network Access (ZTNA) is a network security policy. It provides an additional layer of security to an organization’s network. This layer is a result of the improvement in the network’s access control layer. 

In addition, ZTNA was developed and introduced by Duo Security. It protects the public cloud, where the majority of data and applications are stored. It also protects on-premise networks, where enterprise applications and data are hosted. 

How Are ZTNA Market Players Different From Traditional Network Access Control?

Network access control (NAC) is an access control system that is applied to a network or internetwork, such as an enterprise or home network. It uses information gained from multiple sources. It also provides a single source of authentication to provide access to the whole network. 

With NAC, a dedicated device is deployed on the network. It is done to detect and prevent unauthorized devices from accessing the network. 

The main difference between the NAC market players and ZTNA market players is their scope. Traditional NAC market players – such as Cisco and Juniper Networks – are focused on improving a traditional firewall. 

ZTNA market players are focused on improving the access control layer of the enterprise’s network. This includes Duo Security and Secarma.

Market Guide for Zero Trust Network Access Segmentation

The ZTNA market is segmented based on its deployment type, deployment model, deployment method, and geography. 

The deployment type of the ZTNA is categorized into on-premise and cloud. On-premise deployment is applied to an enterprise’s private cloud infrastructure. Cloud deployment is applied to public cloud providers, such as Amazon Web Services (AWS). 

On-premise deployment is a self-service model, while cloud deployment is a managed service model. The deployment model of ZTNA is categorized into user-based access control and device-based access control. 

User-based access control only uses user identities to secure network access. Device-based access control uses both user records and device identities to secure network access. 

The deployment method of the ZTNA market is also categorized into pre-deployment and post-deployment. Pre-deployment is a one-time process that is applied to the network. Post-deployment is a continuous process that monitors and protects the network. 

The geography of the ZTNA market is categorized into five regions: North America, Europe, Asia Pacific (APAC), Middle East and Africa (MEA), and Latin America. North America has the largest ZTNA market size, followed by Europe. 

Why You Should Read This Guide

As said, the rise of IoT and mobile computing are causing an increase in data security breaches. As a result, organizations are investing in securing their networks. 

ZTNA is one of the possible solutions to this problem. It also provides security to the public cloud, where the majority of data and applications are stored. 

In addition, it provides security to on-premise networks, where enterprise applications and data are hosted. ZTNA is considered a positive security solution for firms that want to protect their data and applications.
