Cybersecurity: Threat detection, endpoint protection, SIEM, vulnerability management. Below, every vendor in the knowledge base headquartered in the EU or the EEA, each checked by us for headquarters, owner, hosting and licence. Non-European vendors are listed at the bottom with a link to their European alternatives.

Why this matters for digital sovereignty
Cybersecurity tools see system logs and network traffic that expose your entire digital environment, and as suppliers they often fall within the scope of the NIS2 directive themselves. Check where telemetry is processed, who the vendor's ultimate owner is and whether on-premise or EU hosting is available.
