ISO 27001 + SOC 2 Compliance Requirements

Quick Answer: ISO 27001 SOC 2 compliance requires you to meet two distinct but overlapping security frameworks. SOC 2 evaluates your controls against the AICPA's Trust Services Criteria, while ISO 27001 requires you to build and certify a full Information Security Management System. Together, they cover hundreds of controls across access, risk, operations, and data protection.

Meeting ISO 27001 SOC 2 compliance requirements means satisfying two separate bodies of requirements that share roughly 80% of their underlying controls. SOC 2 covers five Trust Services Criteria anchored by a mandatory security principle, while ISO 27001 requires a certified Information Security Management System built around 93 controls across four themes.

Pursuing both simultaneously is achievable, but the scope, documentation burden, and audit coordination involved make this one of the more demanding compliance paths a growing company can take. This guide covers what each framework requires, where they overlap, what makes dual compliance hard, and how organizations typically approach it.

Key Takeaways

• ISO 27001 SOC 2 compliance requirements span the AICPA's five Trust Services Criteria and ISO 27001's 93 Annex A controls organized across four control themes.
• Building an ISMS from scratch is the single biggest complexity factor for organizations new to ISO 27001, and it adds significant time before you can even schedule a certification audit.
• Realistically, dual SOC 2 and ISO 27001 compliance takes 8 to 18 months depending on your starting point, scope, and whether you pursue SOC 2 Type 1 or Type 2.
• Handling this in-house typically requires at least one dedicated compliance hire at $84,000 to $132,000 or more per year, before accounting for tooling, auditor fees, or training.
• A managed compliance partner can reduce timeline and cost while covering both certifications under a single coordinated program.

What Are SOC 2 + ISO 27001 ISO 27001 SOC 2 Compliance Requirements?

SOC 2 and ISO 27001 approach information security from different angles, but they reinforce each other well. Understanding what each framework actually requires is the starting point for any dual-compliance program.

SOC 2 Requirements

SOC 2 is governed by the AICPA's Trust Services Criteria. The security criterion is mandatory for every SOC 2 report. The remaining four are optional and selected based on your service commitments.

SOC 2 audits come in two forms. Type 1 evaluates whether your controls are designed correctly at a point in time. Type 2 observes whether those controls operated effectively over a 6 to 12 month period. Most enterprise customers and procurement teams require a SOC 2 Type 2 report.

ISO 27001 Requirements

ISO 27001:2022 requires you to establish, implement, maintain, and continually improve an Information Security Management System. The standard includes 93 controls organized across four themes in Annex A.

Before an ISO 27001 audit, you must produce a Statement of Applicability documenting which controls apply to your organization and why. You must also complete a formal risk assessment and treatment process. These steps are prerequisites, not optional additions.

Because SOC 2 and ISO 27001 share approximately 80% of their underlying control objectives, organizations that build one program thoughtfully can extend it to cover the second without starting over.

Challenges Companies Face When Getting SOC 2 + ISO 27001 Compliant

Dual compliance sounds manageable on paper. In practice, most organizations run into the same set of problems that slow timelines and stretch budgets.

• Underestimating scope: Most teams don't realize how many policies, technical controls, and documented procedures are required across both frameworks before they're halfway through a gap assessment.
• No internal expertise: SOC 2 and ISO 27001 together span IT, security operations, legal, HR, and vendor management. Very few companies have staff with working knowledge across all of these areas simultaneously.
• Ongoing burden: Compliance doesn't stop at certification. Continuous monitoring, annual training, vendor reviews, and policy updates are permanent operating requirements under both frameworks.
• Multi-framework complexity: SOC 2 and ISO 27001 overlap significantly but are not identical. Managing two audit cycles, two sets of evidence, and two auditor relationships at once creates real coordination overhead.
• Auditor back-and-forth: Evidence collection and remediation cycles are time-consuming. Without a structured approach, a single auditor request can trigger weeks of internal scrambling.
• Tool sprawl: Selecting, configuring, and integrating GRC tools, SIEM platforms, endpoint management, and identity controls is a project in itself before compliance work even begins.

What Does It Take to Meet SOC 2 + ISO 27001 ISO 27001 SOC 2 Compliance Requirements?

Getting across the finish line on both frameworks requires work across several distinct areas. Each one takes real time and coordination, and none of them can be skipped.

Documentation and Policy Development

Both frameworks require a substantial library of written policies. ISO 27001 specifically demands a documented ISMS, risk treatment plan, and Statement of Applicability. SOC 2 requires that your controls be formally defined and mapped to the Trust Services Criteria. BEMO creates 18 or more IT policies during implementation to satisfy both frameworks at once.

Technical Controls and Tooling

Access controls, multi-factor authentication, encryption, endpoint protection, and logging are required by both frameworks. You need to select, configure, and maintain the right tools across your entire environment. A Microsoft-native stack covering Entra ID, Intune, Defender, Purview, and Sentinel can satisfy a large portion of the technical requirements for both SOC 2 and ISO 27001.

Ongoing Monitoring and Maintenance

ISO 27001 requires continual improvement and periodic internal audits as a condition of maintaining certification. SOC 2 Type 2 requires that controls operate consistently over time. Both frameworks demand that you monitor your environment actively, not just at audit time. Automated log review, vulnerability scanning, and security awareness training all need to run on a defined schedule.

Auditor Coordination and Evidence Collection

SOC 2 uses a CPA firm for the audit. ISO 27001 uses an accredited certification body. Managing two separate audit relationships, with different evidence requirements and timelines, adds meaningful coordination work. Preparing organized, auditor-ready evidence packages in advance is one of the most effective ways to avoid delays.

Staff Training and Awareness

Both frameworks require documented security awareness training for your team. ISO 27001 People Controls specifically address screening, training, and disciplinary processes. SOC 2 auditors look for evidence that employees understand their security responsibilities. KnowBe4-based training programs with tracked completion rates satisfy both requirements cleanly.

In-House vs Managed: Approaches to SOC 2 + ISO 27001 Compliance

There is no single right way to pursue dual compliance. The best approach depends on your resources, timeline, and how much internal capacity you have to dedicate to a program of this scale.

The DIY path gives you full control but requires significant internal investment in people, tooling, and time. GRC platforms like Drata or Vanta automate evidence collection and provide structured guidance, but you still own the implementation and auditor relationship. A managed compliance partner takes on the build, the tooling, and the coordination, which is especially valuable when you're pursuing two frameworks at the same time.

If you want to understand how these approaches play out in practice, the article on how to manage multiple compliance frameworks covers the operational trade-offs in more detail.

Getting Started With SOC 2 + ISO 27001 Compliance

Getting both certifications doesn't have to mean running two separate programs. A well-structured approach sequences the work so that progress on one framework builds directly toward the other.

1. Book a GAP Assessment: Evaluate your current security posture against both SOC 2 Trust Services Criteria and ISO 27001 Annex A controls. Identify exactly where you stand before committing to a timeline.
2. Get Your Implementation Roadmap: Receive a prioritized plan covering which controls to build first, what tooling to deploy, which policies to write, and how to sequence your two audit timelines.
3. Deploy Controls: Implement technical controls across your environment, configure your GRC platform, build your ISMS documentation, and complete your risk assessment and Statement of Applicability.
4. Achieve and Maintain Compliance: Coordinate with your SOC 2 auditor and ISO 27001 certification body, complete both audits, and transition into ongoing managed compliance to maintain both certifications year over year.

Frequently Asked Questions About SOC 2 + ISO 27001 ISO 27001 SOC 2 Compliance Requirements

What Are the ISO 27001 SOC 2 Compliance Requirements?

ISO 27001 SOC 2 compliance requirements cover two separate but overlapping frameworks. SOC 2 requires controls mapped to the AICPA's five Trust Services Criteria, with security being mandatory. ISO 27001 requires a certified ISMS built around 93 Annex A controls across organizational, people, physical, and technological categories. Because the two frameworks share roughly 80% of their underlying control objectives, a well-designed dual program can satisfy both without duplicating every effort.

How Many Controls Do SOC 2 and ISO 27001 Require Together?

ISO 27001:2022 includes 93 controls across four Annex A themes. SOC 2 does not specify a fixed control count, but your controls must satisfy the Trust Services Criteria relevant to your selected categories. In practice, a dual SOC 2 and ISO 27001 program typically involves 100 or more distinct control activities once you account for both frameworks, your specific scope, and the policies and procedures required to support them.

Do SOC 2 and ISO 27001 Overlap With GDPR Requirements?

Yes. Many of the soc 2 iso 27001 gdpr compliance requirements share common ground, particularly around data protection, access controls, incident response, and vendor management. ISO 27001 Annex A includes controls directly relevant to GDPR obligations, and SOC 2's privacy criterion aligns with several GDPR principles. Organizations subject to all three frameworks can often satisfy a significant portion of GDPR requirements through a well-scoped SOC 2 and ISO 27001 program, though GDPR adds specific legal obligations around data subject rights and consent that require separate attention.

How Long Does It Take to Become SOC 2 + ISO 27001 Compliant?

SOC 2 Type 1 can take one to three months once controls are in place. SOC 2 Type 2 requires 6 to 12 months of control observation. ISO 27001 certification typically takes 6 to 18 months, largely because of the ISMS setup requirement. Running both programs in parallel with a structured approach, BEMO's typical implementation timeline is approximately 8 months for initial implementation before audit coordination begins.

What Does a SOC 2 + ISO 27001 GAP Assessment Include?

A gap assessment evaluates your current security controls, policies, and technical environment against the requirements of both frameworks. It identifies which controls you already have in place, which are missing or partially implemented, and what remediation work is needed before an audit. The output is a prioritized list of gaps and a roadmap for closing them. Starting with a gap assessment is the most reliable way to build a realistic timeline and budget for dual compliance.

Why Choose a Managed Compliance Partner for SOC 2 + ISO 27001?

Pursuing both frameworks simultaneously means managing two audit cycles, two sets of evidence, and an ongoing operational compliance program. Most companies don't have the internal staff to cover IT, security engineering, policy writing, auditor coordination, and continuous monitoring all at once. A managed compliance partner handles all of those functions under one program, typically at a lower total cost than hiring even one dedicated compliance professional. You can read more about what this looks like in practice in BEMO's overview of what a managed compliance provider does.

What Team Does BEMO Assign for SOC 2 + ISO 27001 Compliance?

BEMO assigns a dedicated multi-role team to every client account. That team includes a Customer Success Manager, Project Manager, Delivery Engineer, Security Engineer, SOC Analyst, IT Manager, Support Engineer, and virtual CISO. This structure means you have coverage across every function that dual compliance requires, without hiring any of those roles yourself. Bi-weekly status meetings keep your program on track throughout implementation.
