Diagram showing that Preflight inspects your clusters and generates reports


Jetstack Preflight helps you better understand your Kubernetes environments by constantly scanning for mis-configurations that may be opening security holes, causing costly excess resource usage or making your cluster harder to maintain.

Preflight checks your environment against hundreds of policy rules, all developed by our Kubernetes experts and based on years of working with customers’ production workloads. Data from your environment is continually checked against policy rules and the results are summarised in clear reports that highlight the areas most in need of your attention.

Gain visibility in to the workloads running in your Kubernetes environments

You don’t always know exactly what is running in your Kubernetes clusters, either because developers may have deployed things that you don’t know about, or because configuration changes have left applications running that everyone thinks have been removed.

Preflight allows you to see exactly what is running in each cluster without requiring you to pre-approve every change or specific tools to deploy the clusters or their applications. Preflight will also highlight anything that is particularly high risk because of configuration problems, whether that is potential security holes or excess resource usage.

Automated verification of cluster compliance and conformance

Preflight is a core tool for your Kubernetes team, providing a seamless compliance checker so that your business can move quickly on improving your Infrastructure, whilst having the confidence that it meets the highest standards of best practice.

You can rely on our Kubernetes expertise to catch many common Kubernetes errors.

Easy to digest recommendations

Jetstack hosts a secure web portal to view the latest reports of checks, ensuring that all members of your team are able to evaluate the current state of your Kubernetes infrastructure. The reports highlight the most important items for you to review and deal with before they become costly.

The recommendations are updated with new Kubernetes versions so that you can be sure that you are always up to date with best-practices.

Historical reporting

Preflight maintains a historical record of the reports from your environments. This allows you to confirm the earlier state of your cluster when needed.

It also powers our notification feature that informs you when new violations occur within one your environments.
