The continued, high frequency of successful cyberattacks against today's enterprises has made it abundantly clear that traditional, perimeter-centric security strategies are no longer effective. The failure of resulting architectures is a product not only of the outdated assumption that everything on the inside of an organization's network can be trusted, but also the inability of legacy countermeasures to provide adequate visibility, control, and protection of application traffic transiting associated network boundaries.
This paper discusses the need for and details of a Zero Trust approach to network security. It also itemizes the essential criteria and capabilities required of a Zero Trust solution, explains how the Palo Alto Networks next-generation security platform delivers on these requirements, and provides guidance on how to progressively migrate to a Zero Trust design.
Benefits available to organizations that employ Palo Alto Networks solutions to implement a Zero Trust network include:
� Dramatically improved effectiveness in mitigating data loss via visibility and safe enablement of applications, and detection and prevention of advanced threats;
� greater efficiency for achieving compliance with security and privacy mandates;
� increased ability to securely enable transformative IT initiatives-such as user mobility and infrastructure virtualization; and,
� substantially reduced total cost of ownership (TCO) for IT security.
