Link11: sovereignty score and 8 European alternatives

Link11 is a German provider of DDoS protection and web security. Its offering includes network and web DDoS protection, protection for web applications and APIs, bot management, a web application firewall, a secure CDN and secure DNS. The company describes its network as global, with AI-powered, patented DDoS protection and multi-terabit capacity.

Link11 GmbH is based in Frankfurt am Main, and its imprint names the managing directors and the court where the company is registered. The website names no shareholder or parent company. The company states that it is GDPR-compliant and cites certifications to ISO 27001, BSI C5 and SOC 2 Type 2, and it describes its solutions as made in Germany. Its trust centre does not say where scrubbing centres or customer data are located, so this should be confirmed with the vendor. The website also lists contact points in Israel and North America. For a European organisation the German seat and the stated certifications are the main points to consider.

Why digital sovereignty matters with Link11

Link11 is headquartered in DE 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 Link11 scores best on data residency.

Link11 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 Link11 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
