We need several frameworks. Which one should we do first?
The choice between ISO 27001 and SOC 2 depends on an organisation's strategic objectives and target audience. ISO 27001 establishes a comprehensive Information Security Management System (ISMS) for global recognition and internal maturity. SOC 2 provides assurance reports primarily for US-based customers regarding the security, availability, processing integrity, confidentiality, and privacy of their data. Prioritise ISO 27001 for foundational security and international credibility, or SOC 2 for immediate customer assurance in the US market.
ISO 27001 is an internationally recognised standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Its strength lies in providing a systematic, risk-based approach to managing an organisation's sensitive information, encompassing people, processes, and technology. Achieving ISO 27001 certification demonstrates a commitment to robust risk management and information security best practices, often serving as a foundational security programme that can support compliance with other frameworks. It is particularly beneficial for organisations seeking to operate internationally or those requiring a comprehensive, enterprise-wide approach to information security.
Conversely, a SOC 2 report is an attestation engagement performed by a CPA firm, primarily for service organisations in the United States. It evaluates the effectiveness of controls related to the AICPA Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy. Unlike ISO 27001 certification, SOC 2 results in a report tailored for specific user entities, such as customers, rather than a general certification. Organisations often pursue SOC 2 when their customers, particularly those in regulated industries or handling sensitive data, require assurance regarding the security posture of their service providers. The choice often hinges on whether the immediate business driver is broad international credibility or specific customer assurance within the US market.
