CipherCue tracks 4 vendors headquartered in the European Union or EEA in the Email security category. Listings are editorial; inclusion criteria, ownership, and certification details are visible on each card.
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 email security gateways also reduces exposure to extra-territorial data requests under non-EU legal regimes such as the US CLOUD Act.
The Email security vendors in this directory are headquartered in Belgium, Germany, and Italy. Use the country filter at the top of the page to narrow the list to a specific jurisdiction.
If you run or know an EU-headquartered Email security vendor that should be here, email hello@ciphercue.com with the name and HQ country.
Listings are editorial and not a recommendation. Inclusion, amendment, and removal are at CipherCue's discretion. See our directory listing terms.
