Zero Trust

Framework providing identity, authentication, and policy-based access control for services

A Framework for Zero Trust

MEF’s industry-first Zero Trust framework defines a framework and requirements of identity, authentication, policy management, and access control processes that are continuously and properly constituted, protected, and free from vulnerabilities when implemented and deployed.

The framework also defines service attributes agreed upon between a subscriber and service provider to enable service providers to implement and deliver a broad range of services that comply with Zero Trust principles.

The MEF Zero Trust Framework

With a combination of MEF’s SD-WAN and SASE service standards and a Zero Trust framework, MEF is defining the necessary standards to help the industry successfully secure their digital services.
