ISO 27001 vs. SOC 2: Which Certification is Right for Your Business?
In today’s digital-first world, data security is not just a technical issue—it’s a business imperative. Organisations face increasing pressure from customers, partners, and regulatory bodies to demonstrate their commitment to safeguarding sensitive information. This is where internationally recognised certifications like ISO 27001 and SOC 2 Type 2 come into play.
While both certifications focus on information security, they cater to different audiences and have unique approaches to achieving compliance. This article breaks down the differences, explains their importance, and outlines the benefits and steps involved in obtaining them.
What Is ISO 27001?
ISO 27001 is an international standard for information security management systems (ISMS). It provides a comprehensive framework for establishing, implementing, maintaining, and continually improving information security.
Key Features:
Focuses on the implementation of an ISMS.
Addresses a wide range of security areas, including risk management, access control, and incident response.
Requires a structured, risk-based approach to managing information security.
Target Audience:
Companies operating globally or dealing with international clients.
Industries requiring compliance with stringent security regulations, such as finance, healthcare, and government.
What Is SOC 2 Type 2?
SOC 2 Type 2, developed by the American Institute of Certified Public Accountants (AICPA), is a reporting framework that assesses how an organisation manages data to meet five "trust service principles"—security, availability, processing integrity, confidentiality, and privacy.
Key Features:
Focuses on service providers storing customer data.
Evaluates ongoing operational effectiveness over a specified period.
Provides a report that clients can review to understand the organisation’s security posture.
Target Audience:
SaaS providers and technology companies dealing with customer data.
Organisations globally, including in Australia, seeking assurance of vendor controls, particularly in regulated industries like financial services and healthcare.
