CRA and Cloud Infrastructure: Impact on Hypervisors, Containers, and Firewalls

Hypervisors, container runtimes, and firewalls are classified as Important Class II under the CRA. Here's what cloud infrastructure providers need to do.

Luca Berton7 min read

Cloud infrastructure software faces some of the CRA's most stringent requirements. Hypervisors (EN 304 635), container runtime systems, and firewalls/IDS/IPS (EN 304 636) are classified as Important Class II — requiring mandatory third-party conformity assessment.

What's Affected

  • Hypervisors — VMware ESXi, KVM, Hyper-V, Xen when sold as products
  • Container runtimes — Docker Engine, containerd, CRI-O, Podman when distributed commercially
  • Firewalls — Both hardware appliances and software firewalls (pfSense, OPNsense commercial editions)
  • IDS/IPS — Snort, Suricata, and commercial equivalents

Kubernetes and the CRA

Kubernetes itself is an interesting case. The open-source project (maintained by CNCF) falls under the steward provisions. But commercial Kubernetes distributions — Red Hat OpenShift, Rancher, Tanzu — are commercial products subject to full CRA obligations.

Impact on Platform Engineering

If you build internal developer platforms using these components, you're a user, not a manufacturer. But your vendors must be CRA compliant. This means:

  • Vendor due diligence should include CRA conformity status
  • Component selection should factor in the vendor's CRA readiness
  • Long-term support and security update commitments become contractual requirements
