Link11 is a leading manufacturer of cloud-based cybersecurity solutions, headquartered in Germany with locations across Europe, North America, Asia and the Middle East. Since 2005, the company has pursued one clear goal: to make the internet a safer place and to keep businesses and organizations around the world reliably online.
Link11 strengthens the cyber resilience of networks and critical applications in regulated and critical sectors such as finance, logistics and healthcare. Its product portfolio comprises Network DDoS Protection, Web Application & API Protection (WAAP), Secure CDN and Secure DNS, ensuring the availability and performance of digital services from the network layer through to the application layer.
The AI-driven security platform with patented DDoS protection analyzes incoming traffic in real time, automatically detects attack patterns and continuously adapts to new threats, with no manual intervention required. At the same time, security teams retain full control: whitelists, blacklists and security-relevant configurations can be managed centrally through a clear, intuitive interface.
An in-house 24/7 Security Operations Center (SOC) ensures permanent infrastructure monitoring, proactive operational support and immediate incident response by experienced security experts. Customers receive a fully managed service with a designated point of contact in the EU.
At Link11, digital sovereignty is not a contractual add-on but an architectural principle. The company’s own global network, with a Layer 2 backbone and more than 42 Points of Presence (PoPs), delivers high availability and minimal latency while ensuring EU-compliant processing of all data without access by third countries. As a European provider, Link11 is not subject to the US Cloud Act. For companies in regulated sectors where European data sovereignty is a core requirement, this is a decisive advantage.
Link11 is ISO 27001 certified, meets the requirements of PCI DSS, SOC 2 Type II and BSI C5, and is recognized by the German Federal Office for Information Security (BSI) as a qualified provider for the protection of critical infrastructure. This also helps Link11 customers meet regulatory requirements such as NIS2 and DORA.
