SOC 2 and ISO 27001 both offer strategic frameworks and standards for companies to assess their security controls and systems. But what sets them apart? In this article, you’ll get to know about the difference between ISO 27001 and SOC 2, exploring their key similarities and differences, determining which one is right for your business, and how these certifications can strengthen your overall cybersecurity posture. Want to improve your data security but can’t choose between SOC 2 and ISO 27001? You’re at the right place.
The International Organization of Standardization developed a number of standards, including ISO 27001, which are widely applied in the majority of the world. This standard lays out precise guidelines for implementing tactics like risk assessment, access control, and incident reporting procedures in order to create a robust information security management system. Businesses that handle customer data use it to demonstrate to stakeholders and potential customers the safeguards they have in place. A third-party auditor must confirm that you fulfill the compliance requirements in order for you to receive ISO 27001 certification.
Organizations can safeguard their information security by implementing the policies, procedures, and practices outlined in ISO 27001 security controls. These controls guarantee the accuracy and security of sensitive data while assisting organizations in identifying and mitigating threats.
In order to prove your dedication to information security best practices and obtain a formal certificate stating your compliance with the standard, you must submit to an audit process conducted by a recognized accreditation body to show that your organization has established and maintains a strong Information Security Management System that complies with the standards specified in the ISO 27001 framework. In other words, it means that your organization has fulfilled the requirements to be deemed ISO 27001 compliant.
Policies, documents, and procedures that assist organizations in managing information security are part of ISO 27001 requirements.
The SOC 2 standard, which was created by the American Institute of Certified Public Accountants (AICPA), allows you to record the precautions you take to protect the data of your clients while handling, processing, or storing it. SOC 2 outlines requirements that you must fulfill, such as managing employee data access and spotting fraud. You must hire an auditor to look into your controls and confirm your compliance if you want a SOC 2. After that, the auditor will draft a report outlining your security procedures and assessing your compliance with SOC 2 standards.
A cybersecurity framework called SOC 2 compliance makes sure third-party service providers manage customer data safely. It is intended to safeguard the interests and privacy of clients.
Security, availability, processing integrity, confidentiality, and privacy are the five pillars upon which SOC 2 is built.
An organization must go through an independent audit in order to achieve compliance. The audit results in a report that demonstrates the organization's data management practices. Every organization has its own report.
A cybersecurity framework called SOC 2 evaluates how well a company safeguards private information. Third-party service providers are audited using it.
SOC 2 was created by the American Institute of Certified Public Accountants (AICPA).
Five trust service principles—security, availability, processing integrity, confidentiality, and privacy form the foundation of SOC 2.
The degree to which an organization's controls adhere to these principles is assessed by SOC 2 audits.
The security posture of the company is documented in SOC 2 reports.
A third-party audit SOC 2 is an independent auditor's assessment of a business's security controls. An audit is carried out to make sure the company's controls satisfy the Trust Services Criteria (TSCs).
There are numerous overlapping controls between SOC 2 and other frameworks, including HIPAA, ISO 27001, and NIST-CSF. These controls consist of training, encryption, and access controls.
Overlapping common controls
SOC 2 (System and Organization Controls) is a voluntary framework developed by the American Institute of Certified Public Accountants (AICPA) for service providers handling sensitive customer information. It requires organizations to execute and keep controls that align with the five Trust Services Criteria- Security, Availability, Confidentiality, Processing Integrity, and Privacy.
In contrast, ISO 27001, also known as ISO/IEC 27001, is a worldwide recognized standard that sets the necessities for an effective Information Security Management System (ISMS). Its main objective is safeguarding data by ensuring confidentiality, integrity, and availability while mitigating security risks.
Formerly introduced in 2005 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), ISO 27001 underwent its latest revision in 2022 to reflect evolving cybersecurity challenges.
SOC 2 and ISO 27001 are widely trusted data security frameworks, but they differ in their focus and application. SOC 2 emphasizes cybersecurity controls specifically for customer data, while ISO 27001 concentrates on the overall effectiveness of an organization's Information Security Management System (ISMS).
ISO 27001 and SOC 2 are two widely recognized frameworks for information security and data protection, but they serve different purposes. Understanding their key differences can help businesses choose the right certification for their security and compliance needs.
SOC 2 offers flexibility in its scope, allowing organizations to focus on one or more of the five Trust Services Criteria, with Security being mandatory. The inclusion of other criteria—Availability, Confidentiality, Processing Integrity, and Privacy—depends on the organization’s specific services. This adaptability makes SOC 2 a highly customizable compliance framework, requiring the implementation of 70 to 150 controls based on the selected categories.
ISO 27001, on the other hand, takes a more comprehensive approach. It requires organizations to establish, maintain, and continually improve an Information Security Management System (ISMS). Unlike SOC 2, ISO 27001 mandates the implementation of all 93 controls listed in Annex A, ensuring a standardized approach to information security without the option for selective control adoption.
ISO 27001 and SOC 2 differ significantly in their scope and applicability. ISO 27001 is an international standard designed for organizations of all sizes and industries, focusing on establishing an Information Security Management System (ISMS). In contrast, SOC 2 is a compliance framework primarily applicable to service organizations in North America, emphasizing internal controls related to data security and privacy.
A SOC 2 audit, conducted by a licensed CPA firm, results in an attestation that verifies the effectiveness of an organization’s internal security controls. However, SOC 2 does not provide a formal certification—only an audit report confirming compliance with the selected Trust Services Criteria. The attestation process involves evaluating relevant principles, testing associated controls, and reviewing evidence of their effectiveness.
In contrast, an ISO 27001 audit is performed by an accredited certification body. If an organization successfully meets the standard’s requirements, it receives an official ISO 27001 certification, which serves as formal recognition of its commitment to strict information security practices.
Understanding the distinctions between SOC 2 attestation and ISO 27001 certification can help organizations determine which framework better aligns with their business goals and regulatory requirements.
SOC 2 is predominantly sought after in North America, where it is widely recognized by United States-based companies. However, its reputation for rigorous security standards has led to growing global adoption, particularly among digital businesses. SOC 2 is commonly required by service providers that handle sensitive customer data, including cloud computing firms, SaaS providers, and IT service organizations. Many vendors request SOC 2 reports as part of their security assessment processes.
ISO 27001, in contrast, is a globally recognized standard, valued by organizations across industries such as finance, healthcare, telecommunications, and IT services. While companies may not always be explicitly required to obtain ISO 27001 certification, it provides a competitive edge when dealing with enterprise clients. Businesses pursuing international growth often find ISO 27001 beneficial for demonstrating a commitment to strong information security practices.
The SOC 2 framework is based on 5 Trust Service Criteria, which include 60+ requirements. Organizations are audited according to the selected Trust Service Principles, with the security criterion being mandatory. The SOC 2 audit results in a SOC 2 report, which can be either Type 1 or Type 2.
A SOC 2 Type 1 audit evaluates the design of controls at a specific point in time. A SOC 2 Type 2 audit, however, assesses both the design and operational effectiveness of controls over a period of 6 to 12 months.
The timelines for SOC 2 and ISO 27001 compliance can vary significantly based on several factors.
For SOC 2 Type I, the process typically takes 2-3 months, depending on:
The time required for ISO 27001 and SOC 2 compliance varies. Implementing an Information Security Management System (ISMS) for ISO 27001 generally takes several months, as it involves detailed risk assessment, policy development, and control implementation. SOC 2 compliance, depending on the type (Type 1 vs. Type 2), can take a few months to a year, focusing more on ongoing adherence to its security controls over time.
No, ISO 27001 is a global set of guidelines that includes all the specifications needed to create an ISMS. SOC 2 is a lighter audit that is mainly utilized in North America and can be tailored to the objectives and requirements of the organization being evaluated.
Though their acceptance and popularity vary by region, SOC 2 and ISO 27001 are both globally recognized information security frameworks.
SOC 2 is mostly followed in North America.SOC 2 (Service Organization Control 2) is widely used, especially in the US and Canada. It was created to guarantee that service providers handle client data securely by the American Institute of Certified Public Accountants (AICPA). Cloud-based service providers, SaaS providers, and tech companies that operate in the US market frequently need this framework. If your company mainly works with customers in North America, earning a SOC 2 certification may be crucial to establishing credibility and proving security compliance.The International Standard ISO 27001 is powerful outside of North America.
SOC 2 and ISO 27001 are often compared due to several key similarities. Let’s explore them:
Both ISO 27001 and SOC 2 are voluntary standards, not mandatory regulations like GDPR or HIPAA. Despite this, they are both globally recognized and in high demand because of their rigorous information security requirements.
There is more than 90% overlap in controls between ISO 27001 and SOC 2, as both frameworks aim to protect sensitive data. Common controls include incident management, access controls, physical security, change management, vendor management, and data backups.
Both ISO 27001 and SOC 2 prioritize safeguarding information against unauthorized access and disclosure. SOC 2 focuses on maintaining the privacy and security of customer data, while ISO 27001 is centered on ensuring the security of an organization’s Information Security Management System (ISMS).
ISO 27001 and SOC 2 are widely accepted by customers and serve as important differentiators when seeking enterprise-level contracts. For example, when our client Recruit CRM achieved compliance, they onboarded two enterprise clients within 30-45 days.
Both frameworks require third-party audits. For SOC 2, the audit results in an attestation, while for ISO 27001, it results in formal certification.
Neither framework is a one-time process. Both require ongoing maintenance, regular assessments, and continuous monitoring to stay compliant and improve over time.
I hope this blog has assisted you in determining whether ISO 27001 or SOC 2 is more appropriate for your company. The former is less rigorous but also simpler, less costly, and easier to implement and maintain.

Follow these easy steps to register for the ISO 27001 Foundation exam:
Organizations must submit to an external audit by an authorized entity in order to comply with ISO 27001 or SOC 2. Who performs the audit and how compliance is identified are where the main differences lie.
A recognized ISO 27001-accredited certification body must conduct the audit in order to obtain ISO 27001 certification. The audit will assess the organization's Information Security Management System in relation to the requirements of the standard. Following successful completion, organizations are granted a three-year ISO 27001 certificate of compliance, with yearly surveillance audits to guarantee ongoing compliance.
SOC 2 compliance, on the other hand, necessitates an attestation report that is solely completed by a certified public accountant (CPA) or a CPA firm. Organizations receive a formal attestation report outlining their compliance with the standards in place of a certificate.
Navigating the Difference Between ISO 27001 and SOC 2 depends on your business goals, industry requirements, and target market. If you need a comprehensive, globally recognized security framework, ISO 27001 is the way to go. If your focus is on customer data protection and meeting North American compliance expectations, SOC 2 may be more suitable.
For organizations aiming for stronger security, enhanced trust, and broader business opportunities, obtaining both certifications can be a strategic advantage. Ultimately, investing in strong security frameworks not only ensures compliance but also demonstrates your commitment to data protection and business resilience in an increasingly digital world.
ISO 27001 vs. SOC 2 FAQs address common questions about their purpose, certification process, and key differences.
SOC 2 and ISO 27001 both focus on information security but serve different purposes. SOC 2, developed by AICPA, evaluates service organizations based on five Trust Services Criteria, ensuring customer data protection. It results in an attestation report rather than a certification. ISO 27001 is an international standard that establishes a structured Information Security Management System (ISMS) to manage risks systematically. It involves a formal certification process through audits by accredited bodies. While SOC 2 is more focused on customer data security, ISO 27001 provides a broader, risk-based approach to information security management.
Yes, ISO 27001 and SOC 2 can complement each other. ISO 27001 helps establish a strong Information Security Management System (ISMS), while SOC 2 can address specific gaps and provide flexible assessments to support ongoing improvement and security efforts customized to your needs.
No, they are not equivalent. ISO 27001 is a comprehensive, global standard for building and maintaining an ISMS. SOC 2, on the other hand, is a more targeted audit that is customized based on the organization's needs and is primarily used in North America.
If your vendors or possible partners need SOC 2, ISO 27001 might not be enough. By adhering to both standards, you can improve your security framework and expand your business options.
No, although there is some overlap, SOC 2 and ISO 27001 have different functions. While ISO 27001 includes a more complete and wide-ranging ISMS for overall information security management, SOC 2 concentrates on operational controls and customer data protection.
No, adherence to ISO 27001 is not required. Nonetheless, it provides a robust structure for safeguarding data and might assist your company in adhering to additional legal obligations.
Indeed, ISO 27001 incorporates cybersecurity measures into its ISMS, assisting businesses in creating procedures and systems that guarantee strong cybersecurity compliance.
Being both SOC 2 authenticated and ISO 27001 certified is both feasible and advantageous. Reaching guarantees compliance across industries creates additional commercial opportunities, and shows your dedication to robust security management solutions.
SOC 2 compliance is optional for any organization because it is not required by law. On the other hand, some companies will only work with suppliers who have a SOC 2 certification.
No, unlike HIPAA or GDPR, ISO 27001 is not a mandated legal requirement. Your customer contracts might require ISO 27001, which could make it more difficult for you to attract lucrative clients if you don't have one.
In addition to several other nations that use it, SOC 2 is accepted throughout North America. It isn't an internationally universal standard, though, because it isn't as commonly used outside of North America as ISO 27001.
