+title: Kubernetes Kapsule and Kosmos now support custom security groups
+status: added
+date: 2025-06-25
+category: containers
+product: kubernetes
+---
+
+Starting now, users can provide a security group ID for their existing security groups when creating a Kapsule pool.
+If no security group ID is provided, the pool will use a default preconfigured security group named _Kapsule default security group_, which is shared among all Kapsule pools in the same zone.
+The older behavior of creating a separate security group for each zone where the cluster had at least one pool has been discontinued.
