At MailBlue, the security and reliability of customer data are paramount. That is why we operate in accordance with the international ISO 27001 standard for Information Security Management. This standard defines how organizations must systematically design, manage, and continuously improve their information security.

MailBlue is audited annually by an independent, accredited certification body. During this audit, it is assessed—among other things—whether we comply with the requirements of ISO 27001 in the following areas:

• Security of our IT systems, infrastructure, and applications

• Information security policies and procedures, such as access control, incident management, and data classification

• Protection of personal data and customer information

• Internal processes and responsibilities related to information security

• Supply chain security, including suppliers and sub-processors

• Risk assessments, control measures, and continuous improvement of the ISMS

The ISO 27001 certificate is awarded only when MailBlue can demonstrably meet all requirements of the standard. Certification is reviewed annually and monitored through periodic internal and external audits, ensuring that our information security continues to align with current risks, technologies, and applicable laws and regulations.
