The 4 CISM Domains Explained

The CISM® (Certified Information Security Manager®) qualification from ISACA® is one of the most widely respected credentials for information security professionals. It demonstrates not only technical expertise, but also the strategic insight required to build, manage and improve enterprise-level security programmes.

Since its launch in 2002, CISM has become a globally recognised benchmark for senior roles in information security governance, risk and incident management. It is accredited under ISO/IEC 17024 and was named Best Professional Certification Program in the SC Awards 2025 – a reflection of its continued relevance and high industry regard.

CISM is designed for individuals who manage, design or assess an organisation’s information security function. It is particularly valued by employers looking to fill leadership roles such as CISO, information security manager, risk and compliance officer, or governance lead.
