CNaaS NAC: sovereignty score and 8 European alternatives

CNaaS NAC (Campus Network-as-a-Service Network Admission Control) is software that decides which users and devices may connect to a campus network. Clients authenticate with IEEE 802.1X, with MAC Authentication Bypass (MAB) as a fallback. The software uses RADIUS, registers MAB clients automatically, periodically cleans up inactive clients, supports primary and secondary replication and integrates with Active Directory. Administrators use a web interface or an API. It is server software that you run yourself, with container files in the repository.

CNaaS NAC is developed by SUNET, the Swedish university network, which has been part of the Swedish Research Council (Vetenskapsrådet) since 2001. According to the README it was developed as part of SUNET's managed service. The source code is on GitHub under the BSD-2-Clause licence. Because you can run the software yourself, the access data of your network stays on your own infrastructure.

Why digital sovereignty matters with CNaaS NAC

CNaaS NAC is headquartered in SE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so CNaaS NAC scores best on data residency.

CNaaS NAC 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 CNaaS NAC together with your other vendors and gives a total score, a heatmap and the main risk drivers.
