Syndis: sovereignty score and 8 European alternatives

Syndis is a cybersecurity services firm with its headquarters in Reykjavík, Iceland, and an office in Stockholm. It offers advisory work, offensive security, security training and detection and response. The advisory offer includes virtual CISO services, risk assessments and support with NIS2, DORA, ISO 27001 and GDPR. Offensive security covers penetration testing, red teaming and cloud audits. The detection and response service provides 24/7 SOC monitoring, incident response and digital forensics. Syndis delivers these services as managed engagements to organisations in the Nordic countries.

Syndis is a service provider rather than a software product, so there is no version to host yourself. The company is based in Iceland, a member of the European Economic Area. The website does not say where client data is stored and does not mention a data processing agreement or sub-processors. European organisations that engage Syndis for SOC or testing services should therefore agree in writing where data is processed, who can access it and which legal jurisdiction applies to the company.

Why digital sovereignty matters with Syndis

Syndis is headquartered in IS, which falls under the GDPR through the European Economic Area. No foreign legislation can compel access to your data.

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

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