Open vSwitch: sovereignty score and 8 European alternatives

Open vSwitch is a multilayer virtual switch that can run as a soft switch inside a hypervisor or as the control stack for switching hardware. It is designed for large-scale network automation through programmatic extension and supports standard protocols such as NetFlow, sFlow, IPFIX, RSPAN, LACP and 802.1ag. Open vSwitch can be distributed across several physical servers and integrates with virtualisation and cloud platforms such as Xen, KVM and OpenStack. It runs on Linux, FreeBSD and NetBSD and has been ported to DPDK. The related OVN project adds virtual network abstractions such as overlays and security groups.

Open vSwitch is open source under the Apache 2.0 licence (a few files carry other terms). It is a Linux Foundation Collaborative Project, and the Linux Foundation, a US non-profit organisation, owns the trademarks. There is no vendor-hosted service: you run the software on your own infrastructure, so no data flows to the project, and you can inspect the source code.

Why digital sovereignty matters with Open vSwitch

Open vSwitch 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.

Open vSwitch hosts data outside the EU (self-hosted). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Open vSwitch is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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