When it comes to zero-trust implementation, Zero Trust Network Access (ZTNA) is the most typical form. This implies that all solutions provided here come with a variety of similar attributes. These include a software-based perimeter to limit the exposure of one's assets and apps on the web, and easy customization of access control policies that provide a very detailed level of control.
Moreover, ZTNA architectures are usually quite similar and involve users going through a ZTNA cloud provider to be authenticated. This is normally done either with an internal directory or a cloud-based identity provider. Then, the ZTNA provider checks the user's identity and allows access depending on the specified policy for that user.
