The Malaysian Computer Emergency Response Team (MyCERT) was established to address computer security issues among Malaysian Internet users.

The National ICT Security and Emergency Response Centre (NISER) was born when the National IT Council (NITC) mooted the need for a specialised agency to address ICT security issues in Malaysia. MyCERT became a part of NISER. NISER was placed under MIMOS supervision.

As part of MIMOS Berhad's rationalisation exercise, the Malaysian Cabinet decided for NISER to be separated from MIMOS and established as a Company Limited by Guarantee (CLG), owned by the Government of Malaysia, under the purview of MOSTI.

To address the growing cyber threats in critical areas, the National Information Technology Council (NITC) [Meeting 1/2006] agreed that the National Cyber Security Policy (NCSP) be adopted, with NISER to begin the transformation process to become the Malaysian Cyber Security Centre and given the additional mandate to assist the government in implementing the NCSP.

NISER was officially renamed CyberSecurity Malaysia and registered with the Companies Commission of Malaysia (CCM).

CyberSecurity Malaysia was officially launched by the Prime Minister of Malaysia during the NITC Meeting 1/2007 at Cyberjaya.

CyberSecurity Malaysia obtained full certification in Information Security Management System (ISMS), ISO/IEC 27001.

The government appointed CyberSecurity Malaysia as the sole Certification Body for the evaluation and certification scheme based on MS ISO/IEC 15408: 2005 Information Technology - Security Techniques - Evaluation Criteria for IT Security. This certification body is named Malaysian Common Criteria Certification Body (MyCB).
