Building the Zero Trust Enterprise
Establishing Strong Identity Best Practices with Palo Alto Networks and Okta

This approach to security was never truly effective . Now , it ’ s even less relevant because organisations can no longer inherently trust what ’ s inside of their security perimeter . The perimeter has been eroding for years due to trends like mobility , BYOD , and cloud computing . Now , however , the rapid acceleration of digital transformation in response to the global health crisis has forever changed the IT landscape .
Organisations have been racing to add tools and technologies to meet new and intensifying demands , such as the need to transform the network to support a hybrid workforce or move more data centre applications to the cloud . Under pressure to evolve quickly , many enterprises have been forced to take an ad hoc approach to digital transformation instead of a thoughtful , holistic one . The result ?
