Ambassador Edge Stack, a Kubernetes-native API Gateway, provides simplicity, security, and scalability for some of the largest Kubernetes infrastructures in the world. Ambassador Edge Stack makes it easy to secure microservices with a complete set of security functionality including automatic TLS, authentication and rate limiting. WAF integration is also available. Fine-grained access control is also possible. The API Gateway is a Kubernetes-based ingress controller that supports a wide range of protocols, including gRPC, gRPC Web, TLS termination, and traffic management controls to ensure resource availability.

You can use your favorite debugging software to locally troubleshoot your Kubernetes services. Telepresence, an open-source tool, allows you to run one service locally and connect it to a remote Kubernetes cluster. Telepresence was initially developed by Ambassador Labs, which creates open-source development tools for Kubernetes such as Ambassador and Forge. We welcome all contributions from the community. You can help us by submitting an issue, pull request or reporting a bug. Join our active Slack group to ask questions or inquire about paid support plans. Telepresence is currently under active development. Register to receive updates and announcements. You can quickly debug locally without waiting for a container to be built/push/deployed. Ability to use their favorite local tools such as debugger, IDE, etc. Ability to run large-scale programs that aren't possible locally.

Dash0 is an OpenTelemetry-native observability platform for developers and SRE teams. Metrics, logs, traces, and resources sit in one place, linked by OpenTelemetry semantic conventions, so you move from a slow trace to the logs around it without switching tools or rebuilding context by hand. Telemetry arrives over OTLP. There is no proprietary agent to install and nothing to re-instrument: send the OpenTelemetry data you already collect, and take it elsewhere unchanged if you ever want to. Dash0 ingests Prometheus metrics alongside OpenTelemetry, supports PromQL, and imports existing Prometheus alerting rules and Grafana dashboards. A Kubernetes operator handles collection across clusters, covering workloads, nodes, and control plane. Dashboards are built on Perses and defined as code, so they live in Git and ship through the same review process as the rest of your infrastructure. Checks and alerts are configured the same way. Heatmap drilldowns and filtering on high-cardinality attributes narrow a broad symptom down to the specific requests behind it. AI works on the data rather than in a chat window. Log AI infers severity for logs that arrive without it, extracts patterns, and groups related records, which makes unstructured output from third-party services searchable and filterable. Trace triage uses the SIFT framework to narrow a failing request toward a likely cause. Spend is visible in the product. You can see which services, attributes, and log volumes drive cost and cut them at the source, rather than reconciling a bill after the fact.

Defakto Security offers a robust platform that authenticates every automated interaction by providing temporary, verifiable identities to non-human entities like services, pipelines, AI agents, and machines, thereby removing the need for static credentials, API keys, and enduring privileges. Their comprehensive non-human identity and access management solution facilitates the identification of unmanaged identities across diverse environments such as cloud, on-premises, and hybrid settings, the issuance of dynamic identities in real time based on policy specifications, the enforcement of least-privilege access principles, and the generation of complete audit-ready logs. The solution comprises several modules: Ledger, which ensures ongoing discovery and governance of non-human identities; Mint, which automates the creation of purpose-specific, temporary identities; Ship, which enables secretless CI/CD workflows by eliminating hard-coded credentials; Trim, which optimizes access rights and eliminates excessive privileges for service accounts; and Mind, which safeguards AI agents and large language models using the same identity framework employed for workloads. Each module plays a critical role in enhancing security and streamlining identity management across various operational contexts.
