ISO/IEC 27001:2022

Established by the International Organization for Standardisation (ISO), the ISO 27001 certification follows a globally recognised standard which provides a model for establishing, monitoring, and improving an information security management system. ISO/IEC 27001 promotes a holistic approach to information security: vetting people, policies, and technology. An information security management system implemented according to this standard is a tool for risk management, cyber-resilience, and operational excellence.

ISO 27001 certification is invaluable for monitoring, reviewing, maintaining, and improving a company’s information security management system and gives partner organizations and customers greater confidence in their interactions with MailGuard.

MailGuard is only among a handful of companies to have achieved the ISO/IEC 27001:2022 certification. MailGuard’s certification audit assessment was conducted by GCC, an accredited leading international certification body.
