Note: The core architecture for this pattern was introduced by Isaac Hawley from Tigera. If you are building an AI agent that relies on tool calling, complex routing, or the Model Context Protocol (MCP), you’re not just building a chatbot anymore. You are building an autonomous system with access to your internal APIs. With that power comes a massive security and governance headache, and AI agent security testing is where most teams hit a wall.

Kubernetes networking offers incredible power, but scaling that power often transforms a clean architecture into a tangled web of complexity. Managing traffic flow between hundreds of microservices across dozens of namespaces presents a challenge that touches every layer of the organization, from engineers debugging connections to the architects designing for compliance. The solution to these diverging challenges lies in bringing structure and validation to standard Kubernetes networking.

For years, AI and machine learning workloads lived in the lab. They ran as internal experiments, batch jobs in isolated clusters, or offline data pipelines. Security focused on internal access controls and protecting the data perimeter. That model no longer holds. Today, AI models are increasingly part of production traffic, which is driving new challenges around securing AI workloads in Kubernetes.

The Kubernetes community recently announced that Ingress NGINX, one of the most widely used Ingress controllers, will be retired. This change means teams need to plan for a secure, modern, and future-proof alternative for managing Kubernetes traffic. The Kubernetes SIG Network and the Security Response Committee confirmed that the project will only receive basic maintenance until March 2026. After that, there will be no new releases, bug fixes, or security updates.

If you’ve managed traffic in Kubernetes, you’ve likely navigated the world of Ingress controllers. For years, Ingress has been the standard way of getting our HTTP/S services exposed. But let’s be honest, it often felt like a compromise. We wrestled with controller-specific annotations to unlock critical features, blurred the lines between infrastructure and application concerns, and sometimes wished for richer protocol support or a more standardized approach.

Calico has used eBPF as one of its dataplanes since version 3.13, released more than five years ago. At the time, this was an exciting step forward, introducing a new, innovative data plane that quickly gained traction within the Calico community. Since then, there have been many changes and continued evolution, all thanks to the many adopters of the then-new data plane.

Security as an afterthought is no longer an option and must be deeply embedded in the design and implementation of the products that will be running in the cloud. It is increasingly more critical for many security teams to be almost, if not equally, knowledgeable of the emerging and rapidly evolving technology. Join Manish Sampat from Tigera, as explores the topic in detail with Stan Lee from Paypal.

Compliance automation is a commonly overlooked area of Kubernetes observability. The question is: how do you automate compliance to a security framework that isn’t well understood by DevSecOps teams to begin with? This lack of understanding contributes to mismanaged compliance efforts and in a worst-case scenario, audit exposures and organizational risk. This talk will walk through an example of how to 1) map compliance controls to specific Kubernetes technical configuration 2) automate the assessment of those controls 3) visualize the assessment results. DevSecOps teams will better understand how to incorporate compliance automation alongside security automation.

"Companies of various sizes are building their applications on Kubernetes because it provides significant operational benefits like autoscaling, self-healing, extensibility, and declarative deployment style. However, the operational benefits are only a starting point down the path of building a secure and observable platform that enables the continuous delivery of application workloads. This session shows how to build a fully operational platform, leveraging platform-oriented building blocks to address network security and observability.

As more production workloads migrated to the cloud, the need for Intrusion Detection Systems(IDS) grew to meet compliance and security needs. With the number of workloads in each cluster, IDS needs to be efficient to not take up the shared resources. Techniques such as packet inspection and web application firewalls provide a solid defense against threats and by leveraging the cluster's network control pane, we are able to selectively choose vulnerable workloads and provide an easy way to trace back to the origin of the attack.

Learn how eBPF will bring a richer picture of what's going on in your cluster, without changing your applications. With eBPF we can safely collect information from deep within your applications, wherever they interact with the kernel. For example, collecting detailed socket statistics to root-cause network issues, or pinpointing the precise binary inside a container that made a particular request for your audit trail. This allows for insights into the behavior (and security) of the system that previously would have needed every process to be (manually) instrumented.

Attackers are continuously evolving their techniques to target Kubernetes. They are actively using Kubernetes and Docker functionality in addition to traditional attack surfaces to compromise, gain required privileges and add a backdoor entry to the clusters. A combination of Kubernetes security and observability tools is required to ensure the cloud infrastructure monitoring and lockdown and to enable DevSecOps teams with the right tools for the job.

Kubernetes is being adopted by every major enterprise on the planet for deploying modern, containerized applications. However, containers are highly dynamic and break their existing security models. Tigera provides zero-trust network security and continuous compliance for Kubernetes platforms that enables enterprises to meet their security and compliance requirements.
Tigera’s technology is recognized and trusted as the de facto standard for Kubernetes network security. Our open source software, Tigera Calico, provides production-grade security, and our commercial offerings layer on advanced security capabilities, enterprise controls, and compliance reporting.
Kubernetes Requires a Modern Approach to Security and Compliance:
- Zero-Trust Network Security: With 40% or more of all breaches originating from within the network, you must always have to assume that something has been compromised. Applications running on Kubernetes make heavy use of the network for service to service communication. However, most clusters have been left wide open and are vulnerable to attack. A zero trust approach is the most secure way to lock down your Kubernetes platform.
- Continuous Compliance: Kubernetes is dynamic and constantly changing. Moments after a compliance audit is completed the environment will have changed again. A continuous compliance solution is the only way to prove that your security controls have been implemented properly now and historically.
- Visibility and Traceability: Applications running on Kubernetes Platforms have constantly changing IP addresses and locations that makes it impossible to use traditional flow logs to debug issues and investigate anomalous activity. The only accurate approach is to use Kubernetes labels and workload identity in your netflow logs.
- Multi-cloud and Legacy: Many applications running on Kubernetes will not be greenfield. Applications often need to communicate securely with other systems outside of the cluster, such as on-premises or cloud-based VMs, bare metal servers and databases. To achieve zero trust security for Kubernetes, your security policies must be capable of expanding beyond the cluster.
