The main challenge that Zero Trust Architecture (ZTA) addresses is the access to the corporate

network for third-party vendors. ZTA is a security model that assumes no implicit trust is granted to

assets or user accounts based solely on their physical or network location (i.e., local area networks

versus the internet) or based on asset ownership (enterprise or personally owned)12. It mandates

that any attempt to access resources be authenticated and authorized within a dynamic policy

context.

A .R.T.I.E.'s business model involves contracting with third-party vendors to continue seamless

operations, which presents a security challenge. The traditional VPN-based approach to network

security is not sufficient for this scenario because it does not provide granular control over user

access and does not verify the trustworthiness of devices and users continuously2.

Implementing ZTA would address this challenge by:

Ensuring that all users, even those within the network perimeter, must be authenticated and

authorized to access any corporate resources.

Providing continuous validation of the security posture of both the user and the device before

granting access to resources.

Enabling the organization to apply more granular security controls, which is particularly important

when dealing with third-party vendors who require access to certain parts of the network31.

This approach aligns with the case study’s emphasis on securing the attack surface while supporting

vendor access, as it allows A .R.T.I.E. to grant access based on the principle of least privilege,

reducing the risk of unauthorized access to sensitive data and systems4.
