Securing networks has become a top priority for organizations worldwide in today's rapidly evolving digital landscape. The traditional approach of relying on network perimeters and IP addresses to define security boundaries is no longer effective. With the emergence of disruptive technologies like cloud computing, containers, and microservices, workloads have become dynamic and constantly moving in and out of data centers and the cloud. It calls for a new security model that can adapt to these changes and provide strong protection against evolving threats.
