Clavister: sovereignty score and 8 European alternatives

Clavister is a Swedish cybersecurity company that builds network security products for public administration, energy and utilities, defence and telecom, mainly in Europe. Its portfolio includes next-generation firewalls (NetWall, NetShield, CyberArmour), identity and access management (IdAuth, IdAuth Cloud, IdSign, IdSphere), the TactiGate cross-domain solution and a Tactical Core Network System, plus support, professional services and training. IdAuth Cloud is offered as multi-factor authentication as a service.

Clavister AB is headquartered in Örnsköldsvik, Sweden, and listed on the Nasdaq First North Growth Market. It states that its firewalls are built in Sweden. The sources consulted mention no non-European parent, and no open-source edition is described. For European organisations in defence, public administration or critical infrastructure, a vendor based in Europe can simplify questions of jurisdiction. For cloud-delivered services such as IdAuth Cloud, confirm the hosting location with the vendor.

Why digital sovereignty matters with Clavister

Clavister 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 Clavister scores best on data residency.

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