Organizations often seek compliance with either SOC 2 or ISO 27001 to demonstrate their commitment to protecting customer data. While both frameworks focus on information security, they serve different purposes and have distinct compliance requirements. However, they also share efficiencies that allow businesses to streamline their security and compliance efforts.
This article explores the shared efficiencies and benefits of SOC 2 and ISO 27001, as well as their key differences, helping you decide which one (or both) best fits your business needs.
Pursuing both SOC 2 and ISO 27001 can be highly efficient because they have overlapping security controls and governance requirements. Companies can leverage these similarities to reduce compliance costs and effort.
Both frameworks require similar security practices, including:
Implementing these controls once can satisfy both SOC 2 and ISO 27001.
Both require organizations to document:
A unified security policy can meet both SOC 2 and ISO 27001 requirements.
SOC 2 and ISO 27001 require organizations to maintain logs, audit trails, and documentation of security measures. By using compliance automation tools, businesses can streamline the evidence collection process and reduce audit fatigue.
Both require employees to undergo regular security awareness training. Instead of separate programs, a single security training initiative can satisfy both frameworks.
Vendor security assessments are required in both SOC 2 and ISO 27001. By implementing a standardized vendor risk management process, companies can ensure compliance with both frameworks.
By aligning with either or both frameworks, businesses gain:
Both help businesses comply with GDPR, CCPA, HIPAA, and other data privacy laws, reducing legal risks.
Companies with SOC 2 or ISO 27001 certification are more likely to earn customer trust and close enterprise deals.
A unified compliance approach minimizes duplicate efforts, saving time and money.
SOC 2 and ISO 27001 require incident response plans, ensuring companies can quickly mitigate security threats.

| Scope of Applicability | Service-based (applies to systems handling customer data) | Enterprise-wide (applies to all assets, employees, and processes) |
| Risk Management | Optional risk assessment | Mandatory risk management framework |
| Audit & Reporting | Private report shared with customers | Public certification, valid for 3 years with annual audits |

✅ You are a SaaS or cloud provider targeting North American customers.
✅ Your customers require SOC 2 Type I or Type II reports before signing contracts.

✅ You want to reduce audit complexity by leveraging common security controls.
SOC 2 and ISO 27001 serve different compliance needs but share many efficiencies. If your business is expanding globally, ISO 27001 provides a strong security foundation, while SOC 2 is often required for North American SaaS companies. Many organizations pursue both to increase customer trust, reduce security risks, and streamline compliance efforts.
