Microsegmentation is a method of creating secure zones in data centers and cloud deployments that allows companies to isolate workloads from one another and secure them individually. It’s aimed at making network security more granular.
Microsegmentation vs. VLANs, firewalls and ACLs
Network segmentation isn’t new. Companies have relied on firewalls, virtual local area networks (VLAN) and access control lists (ACL) for network segmentation for years. With microsegmentation, policies are applied to individual workloads for greater attack resistance.
