CAST AI: sovereignty score and 6 European alternatives

CAST AI is a platform that automates Kubernetes workload, infrastructure, cost and performance decisions. It rightsizes workloads, provisions compute, improves bin packing, predicts spot interruptions and extends Karpenter, and it offers cost visibility by cluster, namespace, workload and team, as well as GPU and database optimisation. It supports AWS, Google Cloud, Azure and Oracle Cloud, including EKS, GKE, AKS and OpenShift on AWS, and on-premises clusters. According to the vendor, it connects to existing clusters in minutes and can start in read-only mode. It is operated through a web console.

Cast AI Group Inc., based in Miami, Florida, is the group's data controller, while CAST AI Baltic UAB in Vilnius, Lithuania, is the controller for customers outside the United States. The parent is therefore a US company, which is the CLOUD Act signal. The privacy policy names no hosting location and says data may be stored outside the customer's jurisdiction, with standard contractual clauses used for transfers from the EU. The platform is not open source. The vendor displays ISO 27001 and SOC 2 badges.

Why digital sovereignty matters with CAST AI

CAST AI is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

CAST AI hosts data outside the EU (Global AWS/Azure/GCP). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

CAST AI is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs CAST AI together with your other vendors and gives a total score, a heatmap and the main risk drivers.
