Framework harmonisation is the strategic process of integrating multiple compliance frameworks—such as ISO 27001, SOC 2, GDPR and NIS2—into a unified compliance programme that identifies and leverages overlapping requirements. Rather than managing each framework in isolation with separate controls, evidence and audit processes, harmonisation maps common requirements together so that a single control implementation can satisfy multiple frameworks simultaneously.
Organisations that successfully harmonise their frameworks can reduce compliance effort by 40-60%, as many controls (such as access management, incident response and risk assessment) are required by virtually every standard. This approach also reduces audit fatigue, ensures consistent control implementation across the organisation and makes it far easier to adopt new frameworks in the future by simply mapping them to the existing unified control set.
