Frequently asked questions

Which European SIEM & observability vendors are listed in this directory?

CipherCue tracks 4 vendors headquartered in the European Union or EEA in the SIEM & observability category. Listings are editorial; inclusion criteria, ownership, and certification details are visible on each card.

Why choose an EU-headquartered SIEM & observability vendor over foreign SIEM and log analytics platforms?

EU-headquartered vendors keep customer data inside the European Union by default, sit fully under GDPR jurisdiction, and align procurement with NIS2 and DORA sovereignty expectations. Replacing foreign SIEM and log analytics platforms also reduces exposure to extra-territorial data requests under non-EU legal regimes such as the US CLOUD Act.

In which countries are these SIEM & observability vendors headquartered?

The SIEM & observability vendors in this directory are headquartered in Denmark, France, and Poland. Use the country filter at the top of the page to narrow the list to a specific jurisdiction.
