Odense, Denmark, 27th January 2026, open-source .NET CMS platform vendor, Umbraco, has announced that it has achieved ISO 27001/IEC:2022 certification.

ISO 27001 is an internationally recognized accreditation standard used to verify that an organization’s information security management system aligns with international best practices for its industry.

ISO 27001 provides a proven framework for:

  • Identifying and managing security risks
  • Ensuring consistent and documented security practices
  • Creating accountability and transparency across teams
  • Continuously reviewing and updating security as products and organizations evolve

The ISO 27001 audit and certification applies specifically to Umbraco’s product organization.

Achievement of the certification follows an extensive audit of Umbraco’s people, processes, and technologies by an independent security specialist. The ISO 27001 accreditation shows that Umbraco has demonstrated its ongoing commitment to maintaining the confidentiality, integrity and availability of sensitive data within its products.

Umbraco CEO, Mats Persson, notes that ISO 27001 certification supports the implementation of the Umbraco CMS and associated products by larger, multinational organizations and companies operating in regulated industries.

“We already implement robust information security processes to comply with the NIS2 Directive and EU Cyber Resilience Act. ISO 27001 certification provides our global partners and customers with the reassurance that Umbraco follows international best practices governing the way that our products process, store, and protect sensitive data,” says Persson.

“Gaining the ISO 27001 certification shows that independent auditors have scrutinised the processes used to develop, operate, and maintain Umbraco products, and confirmed that the company reviews and manages security risks on an ongoing basis. This is a milestone on a continuous security journey.”
