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.
Shared Efficiencies Between SOC 2 and ISO 27001
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.
1. Overlapping Security Controls
Both frameworks require similar security practices, including:
- Access control and identity management
- Data encryption and protection
- Incident detection and response
- Monitoring and logging
- Vulnerability management
Implementing these controls once can satisfy both SOC 2 and ISO 27001.
2. Risk Management & Governance Alignment
- ISO 27001 mandates a formal risk assessment and treatment process.
- SOC 2 encourages a risk-based approach, though it’s not mandatory.
- A single risk management program can support both frameworks.
3. Centralized Security Policies & Procedures
Both require organizations to document:
- Access control policies
- Incident response plans
- Business continuity & disaster recovery plans
- Data retention & privacy policies
A unified security policy can meet both SOC 2 and ISO 27001 requirements.
4. Unified Audit & Evidence Collection
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.
5. Security Awareness Training
Both require employees to undergo regular security awareness training. Instead of separate programs, a single security training initiative can satisfy both frameworks.
6. Third-Party Risk Management
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.
Key Business Benefits of SOC 2 and ISO27001 Compliance
By aligning with either or both frameworks, businesses gain:
1. Stronger Market Competitiveness
- SOC 2 is widely recognized in North America, making it essential for SaaS companies and cloud providers serving North American clients.
- ISO 27001 is globally recognized, often required by multinational corporations and European businesses.
- Achieving both enhances credibility and broadens market opportunities.
2. Regulatory & Legal Compliance
Both help businesses comply with GDPR, CCPA, HIPAA, and other data privacy laws, reducing legal risks.
3. Increased Customer Trust
Companies with SOC 2 or ISO 27001 certification are more likely to earn customer trust and close enterprise deals.
4. Cost Savings & Operational Efficiency
A unified compliance approach minimizes duplicate efforts, saving time and money.
5. Enhanced Incident Preparedness
SOC 2 and ISO 27001 require incident response plans, ensuring companies can quickly mitigate security threats.
Key Differences Between SOC 2 and ISO 27001
| Factor | SOC 2 | ISO 27001 |
|---|---|---|
| Primary Purpose | Security attestation for customer data | Establishing an enterprise-wide Information Security Management System (ISMS) |
| Who Requires It? | SaaS, cloud, and tech companies serving US customers | Any business needing an internationally recognized security framework |
| Certification vs. Attestation | Attestation report issued by a CPA firm (not a formal certification) | Certification issued by an accredited body (valid for 3 years) |
| Framework Structure | Based on AICPA Trust Services Criteria (TSC) (Security, Availability, Processing Integrity, Confidentiality, Privacy) | Based on Annex A of ISO 27001, covering 93 security controls |
| 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 |
| Recognition | Strong in North America | Internationally recognized |
| Implementation Timeline | Type I: Weeks, Type II: 3–12 months | 4–12 months |
Which One Should Your Business Pursue?
Choose SOC 2 If:
✅ 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 prove ongoing security effectiveness over time.
Choose ISO 27001 If:
✅ You operate internationally and need a globally recognized certification.
✅ You need a structured, long-term security management framework.
✅ You want to establish an ISMS with continuous risk assessment.
Consider Both If:
✅ You want maximum market coverage (North America + global).
✅ You’re targeting enterprise clients that require one or both certifications.
✅ 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.
