What is Microsegmentation in Cybersecurity?
Cloud Security
Version 1.0 · Published April 2026 · Last verified April 2026
Microsegmentation divides a network into small, isolated segments where each workload or application gets its own security policies. It restricts lateral movement by enforcing access controls between individual workloads, not just between network subnets. Microsegmentation can be implemented at the hypervisor, host agent, or cloud-native network layer.
Why Microsegmentation Matters for Your Cybersecurity Career
Lateral movement after initial compromise is how attackers escalate from a single breached system to full network control. Microsegmentation stops this pattern. Security engineers who can design and deploy microsegmentation policies help organizations contain breaches before they spread. This skill is increasingly required in cloud security and zero trust job descriptions.
