Current network security architectures were designed with the enterprise data center as the focal point for access needs. Digital business has driven new IT architectures like cloud and edge computing and work-from-anywhere initiatives, which have, in turn, inverted access requirements, with more users, devices, applications, services and data located outside of an enterprise than inside. The COVID-19 pandemic accelerated these trends.

Network security models based on data center perimeter security using a collection of security appliances are ill-suited to address the dynamic needs of a modern digital business and its distributed digital workforce. The legacy perimeter must transform into a set of cloud-based, converged capabilities created when and where an enterprise needs them, that is, a dynamically created, policy-based secure access service edge .

At the same time, enterprises are increasingly pursuing zero trust strategies, but finding meaningful implementations of zero trust principles challenging. Delivering a zero trust security posture is an integral part of emerging SASE offerings. Zero trust networking models replace implicit trust (zero implicit trust is the goal) with continuously assessed risk/trust levels. They adapt the amount of explicit trust granted for interactions as context surrounding the interactions changes.

Find out now how to get a zero trust security posture while keeping complexity manageable.
