Umbraco
✓ Verified by EU AltsOpen-source .NET CMS trusted by 800,000+ websites — a Danish alternative to WordPress.
Overview
Umbraco is a Odense, Denmark-based European company building cms and open source software since 2003. Despite its EU base, EU Alts has verified that Umbraco is owned by Monterro (Sweden) — majority owner since 2021; minority stakes held by Bonnier Capital, Alcur Fonder, and Grenspecialisten (all Sweden) (Denmark (Umbraco A/S, HQ Odense); majority-owned by Monterro, a Sweden-based growth equity firm), and hosts customer data with Microsoft Azure (with Cloudflare for CDN/security) in Customer-selectable region; EU data centers available, plus a US (Virginia) option added in 2022, so it may still fall under the reach of the US CLOUD Act — worth weighing against WordPress / WP Engine on this specific point.
Why European teams pick Umbraco
Teams in Europe still consider Umbraco for its cms product and Denmark presence, operating since 2003, but unlike a fully EU-owned provider, Umbraco is owned by Monterro (Sweden) — majority owner since 2021; minority stakes held by Bonnier Capital, Alcur Fonder, and Grenspecialisten (all Sweden) (Denmark (Umbraco A/S, HQ Odense); majority-owned by Monterro, a Sweden-based growth equity firm), and hosts customer data with Microsoft Azure (with Cloudflare for CDN/security) in Customer-selectable region; EU data centers available, plus a US (Virginia) option added in 2022 — so it does not fully avoid US CLOUD Act exposure the way some other alternatives to WordPress / WP Engine do.

Frequently asked questions
What does Umbraco do?
Umbraco is open-source .net cms trusted by 800,000+ websites — a danish alternative to wordpress. It is listed under cms and open source on EU Alts because its core functionality serves teams looking for a European cms tool with EU data residency, typically as a switch away from WordPress / WP Engine.
Is Umbraco GDPR compliant?
Umbraco is headquartered in Odense, Denmark and processes user data under the GDPR by default. Customer data processing is supervised by Denmark's data protection authority, the Datatilsynet (Danish DPA). However, EU Alts has verified that Umbraco is owned by Monterro (Sweden) — majority owner since 2021; minority stakes held by Bonnier Capital, Alcur Fonder, and Grenspecialisten (all Sweden) (Denmark (Umbraco A/S, HQ Odense); majority-owned by Monterro, a Sweden-based growth equity firm), and hosts customer data with Microsoft Azure (with Cloudflare for CDN/security) in Customer-selectable region; EU data centers available, plus a US (Virginia) option added in 2022, which means — unlike a fully EU-owned provider — it may still be reachable under the US CLOUD Act, similar to WordPress / WP Engine in that respect.
How do teams switch from WordPress / WP Engine to Umbraco?
Teams evaluating a move from WordPress / WP Engine to Umbraco should note: Umbraco is owned by Monterro (Sweden) — majority owner since 2021; minority stakes held by Bonnier Capital, Alcur Fonder, and Grenspecialisten (all Sweden) (Denmark (Umbraco A/S, HQ Odense); majority-owned by Monterro, a Sweden-based growth equity firm), and hosts customer data with Microsoft Azure (with Cloudflare for CDN/security) in Customer-selectable region; EU data centers available, plus a US (Virginia) option added in 2022, so this switch narrows but may not fully close the US CLOUD Act gap. Weigh that against the cms workflow fit before treating it as a complete Schrems II fix.
