# Security PMK works off the CISA recommended Zero Trust Security model. This allows users to uniquely define an increasingly granular user/group policy specification. PMK integrates with your organization's existing Single-Sign On (SSO) solution to enable SSO across distributed infrastructures and locations. In every managed deployment of PMK, security patches and rolling updates/upgrades for your Kubernetes clusters are automatically delivered to your platform to ensure security conformity. For air-gapped deployment of PMK, patches and updates are delivered at a pre-defined regular cadence to enable you to ensure full compliance with your organization's security policies. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
