Trust, but Verify: Making Network Segmentation Visible

Hands-on workshop

Virtual

Making Network Segmentation Observable

Network segmentation is a foundational security and reliability control, but it’s only effective when you can observe it.

In this workshop, you’ll get hands-on with Hubble to make Kubernetes network traffic visible and understandable. By working with real flow data, DNS context, and protocol awareness, you’ll learn how to validate segmentation policies, uncover unexpected connectivity, and troubleshoot communication paths with confidence.

You will learn how to:

• Visualize real network flows to understand and validate network segmentation
• Apply identity-aware, DNS-aware, and protocol-aware visibility to troubleshoot connectivity issues
• Detect unintended or unexpected communication paths across segmented workloads
• Use Hubble (UI, CLI, and historical data) to investigate and explain network behavior in Kubernetes

Access the lab from this session.

Network segmentation only works if you can see it in action. Watch the recording of this workshop to discover how Hubble exposes real traffic flows, identities, and protocols to validate and troubleshoot segmentation in Kubernetes environments.

• The Network Segmentation Spectrum

  Cyber attacks show how quickly intruders can move laterally when segmentation is weak. The old perimeter firewall model is no longer enough. Segmentation now exists across a spectrum: macro controls that separate zones, micro policies between workloads, and runtime enforcement that ties security to the processes themselves. Cisco’s Hybrid Mesh Firewall strategy, with Hypershield, Secure Workload, and the Isovalent Enterprise Platform, brings these layers together to secure containers, VMs, and AI workloads.
