Introduction to Cisco Secure Workload, Release 3.9.1.28

The Cisco Secure Workload platform is designed to provide comprehensive workload security by establishing a micro perimeter around every workload. The micro perimeter is available across your on-premises and multicloud environment using firewall and segmentation, compliance and vulnerability tracking, behavior-based anomaly detection, and workload isolation. The platform uses advanced analytics and algorithmic approaches to offer these capabilities.

This document describes the features, bug fixes, and behavior changes, if any, in Cisco Secure Workload, Release 3.9.1.28.

For information on how to upgrade the software version, see Cisco Secure Workload Upgrade Guide.


Note


As a best practice, we recommend to patch a cluster to the latest available patch version before performing a major version upgrade.
