    Defining SOC 2 and ISO 27001

    Before diving deeper into the comparison between SOC 2 and ISO 27001, it’s essential to understand the fundamental concepts of each framework. In this section, we’ll provide clear definitions and explanations for both SOC 2 and ISO 27001.

    SOC 2

    SOC 2, which stands for System and Organization Controls 2, is a framework developed by the American Institute of Certified Public Accountants (AICPA). It is primarily designed for service organizations, including cloud service providers, software-as-a-service (SaaS) companies, data centers, and other entities that handle customer data and provide services.

    Purpose of SOC 2:

    • SOC 2 focuses on assessing and reporting on the controls and processes related to customer data security, availability, processing integrity, confidentiality, and privacy.
    • It aims to assure customers, stakeholders, and business partners that a service organization has implemented adequate security measures to protect their data.

    Key Characteristics of SOC 2:

    • Independent third-party auditors typically issue SOC 2 reports.
    • There are two main types of SOC 2 reports: Type I and Type II. Type I reports describe the system and controls at a specific point in time, while Type II reports cover a period and assess the effectiveness of controls.
    • SOC 2 criteria include five trust service principles: security, availability, processing integrity, confidentiality, and privacy. Service organizations can select which of these principles are relevant to their services.

    SOC 2 or ISO 27001 for compliance?

    Compliance vs. Certification

    Organizations that adhere to SOC 2 standards undergo audits performed by qualified independent auditors. These audits are meticulous and thorough, evaluating whether the organization’s controls and practices align precisely with the criteria defined within the SOC 2 framework.

    Successful completion of a SOC 2 audit results in the issuance of SOC 2 reports. These reports serve as a comprehensive record of the audit process, detailing the results and findings. They provide invaluable transparency and assurance to clients, partners, and stakeholders, helping them understand the organization’s commitment to data security and privacy.

    ISO 27001 certification represents a formal recognition by accredited third-party certification bodies that an organization has successfully met the stringent requirements outlined in the standard. ISO 27001 takes a holistic approach to information security management. 

    Achieving ISO 27001 certification is a comprehensive process. Organizations seeking this certification must undergo a series of assessments and audits conducted by accredited certification bodies. These audits rigorously evaluate whether the organization has effectively implemented the necessary controls and practices to ensure robust information security.

    Geographic Focus

    SOC 2 is predominantly used in North America, especially in the United States, due to its robust framework for assessing and reporting on customer data security, availability, processing integrity, confidentiality, and privacy. This compliance standard is highly favored by service providers seeking to demonstrate their commitment to stringent security practices to clients and stakeholders within the region.

    Furthermore, SOC 2 has also gained significant recognition in Canada. One contributing factor to its adoption in Canada is the endorsement of SOC 2 by CPA Canada. This endorsement signifies that SOC 2 aligns well with the principles and standards upheld by CPA Canada, making it a valuable choice for Canadian organizations aiming to showcase their dedication to data security and privacy.

    ISO 27001 is a globally recognized Information Security Management Systems (ISMS) standard, offering a comprehensive framework that transcends geographical boundaries. It is not bound by regional or industry-specific constraints, making it adaptable to the diverse needs of organizations worldwide. This flexibility allows organizations to tailor their ISMS to their unique business processes, risk profiles, and regulatory requirements while adhering to globally acknowledged best practices. The universal appeal makes it an ideal choice for organizations of all sizes and types, regardless of location or industry.


    SOC 2 allows organizations to customize controls and criteria to align precisely with their services. This means that an organization can select and implement controls that are directly relevant to the security, availability, processing integrity, confidentiality, and privacy of customer data within their specific service offering. For example, a cloud hosting provider may emphasize different controls compared to a data analytics company, and SOC 2 accommodates these variations.This adaptability makes it suitable for various service types, accommodating diverse security and privacy demands.

    While ISO 27001 is a highly regarded information security management standard, people generally consider it less flexible than SOC 2. This distinction arises from the inherent nature of ISO 27001 as a comprehensive and structured framework for managing information security.

    ISO 27001 promotes a highly structured approach to security management. It requires organizations to assess and implement all 114 controls, ensuring comprehensive coverage of information security risks. This structured approach is advantageous in that it leaves little room for gaps in security coverage.
