Microsegmentation
Microsegmentation is a network security technique that divides larger networks into smaller, isolated segments, each with its own set of access controls and policies. This segmentation occurs at the workload or application level, enabling fine-grained control over east-west traffic within data centers, cloud environments, or hybrid infrastructures.
Unlike traditional perimeter-based models, microsegmentation enforces security policies inside the network, allowing organizations to isolate workloads from one another, regardless of where they reside. This reduces the risk of lateral movement by attackers, limits the blast radius of security incidents, and improves overall visibility into traffic flows.
Policies within microsegmentation are typically dynamic, enforced based on identity, context, or behavior rather than static IPs or subnets. This allows for adaptive security aligned with modern infrastructure—whether virtualized, containerized, or distributed across multiple environments.
