SOC 2 vs. ISO 27001

If you’re selling software to enterprise customers, expanding into new markets, or preparing for bigger security reviews, you’ve probably encountered the same question:

Should we get SOC 2 or ISO 27001 first?

Both are widely recognized information security standards. Both can strengthen customer trust. Both require organizations to establish and demonstrate effective security controls. And both can become important during enterprise procurement and vendor risk assessments.

But they are not the same thing.

SOC 2 is an attestation report based on the AICPA Trust Services Criteria, while ISO/IEC 27001 is an international standard for establishing and continually improving an Information Security Management System (ISMS).

So, which one should you pursue first?

There isn’t a universal answer. The right starting point depends on who your customers are, where you sell, what they expect, how mature your security program is, and where you plan to take the business next.

Accorian helps organizations navigate these decisions through cybersecurity assessments, compliance advisory, testing, and technology-enabled compliance. With experience across frameworks including SOC 2, ISO 27001, HITRUST, HIPAA, PCI DSS, CMMC, and emerging AI governance standards, Accorian can help organizations build a compliance program that scales beyond a single audit.

The good news is that choosing one does not mean starting from scratch when you pursue the other.

In fact, SOC 2 and ISO 27001 have significant areas of overlap.

SOC 2 vs. ISO 27001: The Short Answer

Choose SOC 2 first when your immediate priority is meeting customer or prospect demands for a SOC 2 report, particularly in the U.S. technology and SaaS market.

Consider ISO 27001 first when your priority is establishing a formal information security management system or demonstrating internationally recognized information security practices.

If you’re selling globally, serving enterprise customers, or expecting your compliance requirements to expand, you may eventually need both SOC 2 and ISO 27001. The important thing is to build your security program with both frameworks in mind from the beginning.

At a glance

SOC 2

• Developed by the AICPA
• Based on the Trust Services Criteria
• Commonly requested by technology and SaaS customers
• Produces an independent auditor’s report
• Can cover Security, Availability, Processing Integrity, Confidentiality, and Privacy
• Particularly prevalent in North American markets

ISO 27001

• International information security standard
• Establishes an Information Security Management System
• Based on a risk management approach
• Can lead to independent certification
• Used across industries and geographic markets
• Particularly relevant for organizations operating internationally

Neither framework automatically replaces the other.

What Is SOC 2?

SOC 2, or System and Organization Controls 2, is an AICPA framework for reporting on controls at service organizations relevant to security, availability, processing integrity, confidentiality, or privacy. It is particularly common among:

• SaaS companies
• Cloud service providers
• Technology companies
• Fintech organizations
• Data processors
• Managed service providers
• B2B software companies

Why does SOC 2 matter to these organizations?

Because customers want to know that the companies handling their data have appropriate controls in place. A prospective enterprise customer may ask:

How do you protect our data?

A SOC 2 report provides independent assurance about the organization’s controls within the scope of the examination.

What Are the SOC 2 Trust Services Criteria?

SOC 2 is built around five Trust Services Criteria:

• Security: Controls designed to protect systems and information against unauthorized access, disclosure, or damage.
• Availability: Controls related to the availability of systems and services as committed or agreed.
• Processing Integrity: Controls designed to ensure that system processing is complete, valid, accurate, timely, and authorized.
• Confidentiality: Controls related to protecting information designated as confidential.
• Privacy: Controls related to the collection, use, retention, disclosure, and disposal of personal information.

Security is relevant to every SOC 2 examination. Organizations can determine whether the other criteria are relevant based on their services, systems, and customer commitments.

SOC 2 Type I vs. Type II

This is another important distinction.

SOC 2 Type I evaluates whether controls are suitably designed and implemented as of a specified date.

SOC 2 Type II evaluates the design and operating effectiveness of controls over a specified period.

For organizations building customer trust, a Type II report can provide evidence of how controls operated over time rather than only showing their design at a single point.

What Is ISO 27001?

ISO/IEC 27001 is an international standard that specifies requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Instead of focusing only on individual security controls, ISO 27001 takes a management-system approach. That means organizations need to establish a structured way to:

• Understand their information security context.
• Identify and assess risks.
• Determine how those risks should be treated.
• Establish appropriate controls.
• Monitor performance.
• Conduct internal audits.
• Review the ISMS at the management level.
• Continually improve the system.

ISO 27001 can be implemented by organizations of different sizes and across industries.

What Is an ISMS?

An Information Security Management System is the organizational framework used to manage information security risks. It brings together:

• People
• Processes
• Policies
• Technology
• Risk management
• Security controls
• Governance
• Monitoring
• Continuous improvement

That’s an important distinction. ISO 27001 isn’t simply a list of technical security controls. It is a structured management system for managing information security.

SOC 2 vs. ISO 27001: What’s the Difference?

At first glance, SOC 2 and ISO 27001 can look remarkably similar. Both involve security controls. Both require documentation. Both require evidence. Both address risk. Both can involve independent assessment. The difference is in how they are structured and what they are designed to demonstrate.

1. SOC 2 Is an Attestation Report. ISO 27001 Is a Management System Standard.

SOC 2 results in an independent examination report based on the applicable Trust Services Criteria.

ISO 27001 provides requirements for establishing and operating an ISMS and can be used as the basis for certification.

That’s why saying that an organization is “SOC 2 certified” is technically inaccurate. SOC 2 results in a report, while ISO 27001 can result in certification.

2. SOC 2 Is Especially Common in the U.S. Technology Market

SOC 2 has become deeply embedded in enterprise technology procurement, particularly among U.S. companies and SaaS providers.

If your sales team regularly hears:

“Do you have a SOC 2 report?”

SOC 2 may be an important business requirement.

ISO 27001 has broader international recognition and is widely used across countries and industries.

3. ISO 27001 Puts the ISMS at the Center

ISO 27001 requires organizations to establish and continually improve an ISMS.

SOC 2 is centered around demonstrating that relevant controls meet the applicable Trust Services Criteria.

This means ISO 27001 can provide a broader organizational structure for information security governance, while SOC 2 can provide detailed assurance about controls within the examination scope.

4. The Assurance Looks Different

With ISO 27001, an organization can pursue certification through an independent certification process.

With SOC 2, an independent service auditor examines the organization’s system and controls and issues a report.

Customers may ask for either, depending on their procurement requirements. And increasingly, they may ask for both.

SOC 2 vs. ISO 27001: What Do They Have in Common?

Here’s where things get interesting. You don’t necessarily need to build two completely separate security programs. SOC 2 and ISO 27001 have significant overlap across areas such as:

• Access control
• Risk management
• Security policies
• Incident response
• Change management
• Vendor management
• Business continuity
• Security monitoring
• Employee security awareness
• Data protection
• Asset management
• Evidence management

The exact overlap depends on the organization’s scope, controls, and implementation. This creates an opportunity for common control mapping. Instead of asking:

“How do we build SOC 2?”

and later:

“How do we start ISO 27001 from scratch?”

A better question is:

“How do we build a security program that can support both?”

That’s where organizations can save significant time and reduce duplicate compliance work.

So, Which Should You Get First?

This is the question most organizations actually care about. And the answer starts with your customers.

Choose SOC 2 First If Your Customers Are Asking for It

SOC 2 may be the logical starting point if:

• Your customers are primarily in North America.
• You’re a SaaS or technology company.
• Enterprise prospects regularly request a SOC 2 report.
• Security questionnaires are slowing down your sales cycle.
• Procurement teams require independent assurance.
• Your immediate goal is to support enterprise customer acquisition.

For a growing SaaS company, compliance can quickly move from a security initiative to a sales requirement. If a prospect says SOC 2 is required before procurement can move forward, that’s a very different situation from pursuing SOC 2 simply because it is a popular framework. Start with the requirement that’s actually affecting your business.

Choose ISO 27001 First If You’re Building for Global Markets

ISO 27001 may be a more relevant starting point when:

• You sell across multiple countries.
• Your customers are distributed globally.
• International enterprise customers request ISO 27001.
• You want to formalize your ISMS.
• Risk management is central to your security strategy.
• Your organization expects to pursue additional ISO standards.
• You want an internationally recognized certification.

ISO 27001’s international applicability makes it particularly relevant for companies building a global security and compliance program.

What If You Need Both?

This is where many organizations overcomplicate things. If both SOC 2 and ISO 27001 are on your roadmap, don’t treat them as two unrelated compliance projects. Instead, build the common foundation first. For example, you may already have:

• An access control program
• Security policies
• Vendor risk management
• Incident response
• Employee security training
• Risk assessments
• Asset inventories
• Security monitoring
• Business continuity processes

Those capabilities can support multiple compliance frameworks. The next step is to map controls across the frameworks and identify what’s missing. This is often more efficient than implementing one framework and then rebuilding the program when the second requirement arrives.

Can You Get SOC 2 and ISO 27001 at the Same Time?

Yes.

Organizations can pursue SOC 2 and ISO 27001 concurrently or sequentially. The right approach depends on resources, scope, audit schedules, customer deadlines, and security maturity. If you’re starting from zero, implementing both simultaneously can create significant coordination requirements. But if your organization already has a mature security program, common controls can make the combined approach more manageable. The key is to establish a single source of truth for policies, controls, risks, evidence, and remediation.

SOC 2 vs. ISO 27001 for SaaS Companies

SaaS companies are among the organizations most likely to encounter both frameworks.

Why?

Because SaaS providers often handle customer data, operate cloud infrastructure, rely on third-party services, and sell into enterprise procurement environments.

A SaaS company might hear:

U.S. prospect:
“Do you have SOC 2 Type II?”

International prospect:
“Are you ISO 27001 certified?”

Large enterprise:
“Please complete our security questionnaire and provide your latest audit or certification documentation.”

That’s why compliance strategy should be based on your customer profile and growth strategy, not just the framework that seems easiest to implement.

SOC 2 vs. ISO 27001 for Startups

Startups don’t necessarily need every compliance framework on day one. But waiting until a major prospect demands compliance can create unnecessary pressure. A better approach is to identify where the business is going.

Ask:

• Who are we selling to?
• Which markets are we entering?
• What security requirements appear repeatedly in customer questionnaires?
• What regulations apply to our business?
• Which frameworks might we need over the next 12 to 24 months?
• What controls do we already have?
• Where are the biggest gaps?

If you’re expecting enterprise sales, building foundational security controls early can make later compliance significantly easier. The goal isn’t to create a massive compliance program before you need one. It’s to avoid creating a security program that you’ll have to rebuild six months later.

SOC 2 vs. ISO 27001: Cost and Timeline

There’s no universal price tag or timeline for either framework. Your actual effort depends on:

• Organization size
• Number of employees
• Number of systems
• Scope
• Existing security controls
• Security maturity
• Number of locations
• Third-party dependencies
• Evidence availability
• Remediation requirements
• Auditor or certification body fees
• Internal resources
• Compliance technology

A company with a mature security program may have a very different starting point from a startup building its controls for the first time. That’s why a readiness assessment is often more useful than relying on generic cost or timeline estimates. Before committing to an audit or certification, determine:

• What do we already have?
• What is missing?
• What needs remediation?
• What evidence can we produce?
• What needs to change operationally?

Those answers give you a much more realistic implementation roadmap.

Does SOC 2 Replace ISO 27001?

No.

A SOC 2 report does not make an organization ISO 27001 certified. The two frameworks have different requirements and assurance models. If a customer specifically requires ISO 27001 certification, a SOC 2 report generally won’t satisfy that requirement.

The reverse is also true.

ISO 27001 certification does not automatically provide a SOC 2 report. This is why organizations should understand what their customers actually require, rather than assuming one framework can substitute for another.

Can SOC 2 Controls Be Used for ISO 27001?

Yes, many existing SOC 2 controls can contribute to an ISO 27001 program. However, SOC 2 compliance does not automatically satisfy ISO 27001 requirements. A proper mapping exercise should identify:

• Existing controls
• Common requirements
• Control gaps
• Additional ISO 27001 requirements
• Documentation gaps
• Risk management requirements
• Evidence requirements

The same principle applies when moving from ISO 27001 toward SOC 2. This is why SOC 2 to ISO 27001 mapping and ISO 27001 to SOC 2 mapping are valuable exercises for organizations pursuing multiple frameworks.

How to Build One Security Program for Both

If both frameworks are on your roadmap, start with the foundation.

1. Define your scope: Identify the products, services, systems, locations, employees, and data included in the compliance program.
2. Build your risk management process: Identify information security risks and establish a repeatable process for evaluating and treating them.
3. Establish core security controls: Focus on areas such as Identity and access management, Vulnerability management, Security monitoring, Incident response, Asset management, Data protection, Vendor risk management, Business continuity, and Change management.
4. Centralize evidence: Don’t let audit evidence live across random emails, spreadsheets, screenshots, and shared folders. Create a structured evidence management process.
5. Map controls: Map common controls to SOC 2 and ISO 27001 requirements.
6. Automate wherever possible: Automate evidence collection, control monitoring, task assignments, reminders, and compliance workflows where practical.
7. Maintain continuous readiness: Compliance shouldn’t begin three months before the audit.

Your controls should operate continuously, with evidence generated as part of normal business operations.

Why Continuous Compliance Matters

One of the biggest mistakes organizations make is treating compliance as an annual event.

Security doesn’t operate once a year.

Your employees join and leave.

Access changes.

Vendors change.

Infrastructure changes.

Applications are deployed.

Policies evolve.

Risks change.

So your compliance program needs to keep up.

Continuous compliance means continuously monitoring the controls, evidence, risks, and requirements that support your security program rather than scrambling to reconstruct everything before an assessment.

This becomes even more important when you’re managing multiple frameworks.

How GORICO Helps With SOC 2 and ISO 27001

Managing multiple frameworks manually can quickly turn into a maze of spreadsheets, evidence requests, screenshots, emails, and duplicated control work. That’s where GORICO, Accorian’s AI-powered continuous compliance platform, can help. GORICO helps organizations centralize compliance workflows and manage activities across multiple frameworks, including:

• SOC 2
• ISO 27001
• HIPAA
• HITRUST

• CMMC
• NIST frameworks
• ISO 42001
• Other organizational and regulatory requirements

Capabilities include AI Policy & Procedures Review, AI Evidence Manager, AI Posture Assessment, control mapping, readiness workflows, evidence traceability, and AI-powered compliance automation.

Instead of building separate compliance processes for every framework, organizations can establish a unified control and evidence environment and map requirements across standards. That matters when your roadmap looks like:

SOC 2 → ISO 27001 → HITRUST → ISO 42001

rather than stopping after the first audit.

Frequently Asked Questions About SOC 2 vs. ISO 27001

1. Is SOC 2 better than ISO 27001?

Neither is universally better. SOC 2 and ISO 27001 serve different purposes and use different assurance models. The right choice depends on customer requirements, target markets, business objectives, and the maturity of your information security program.

2. Should I get SOC 2 or ISO 27001 first?

If your customers primarily request SOC 2 reports, SOC 2 may be the more immediate priority. If your organization operates globally or needs an internationally recognized ISMS certification, ISO 27001 may be more relevant. Organizations targeting both markets may eventually pursue both.

3. Can I have both SOC 2 and ISO 27001?

Yes. Many organizations pursue both because the frameworks have overlapping security controls and can address different customer and market requirements.

4. Is SOC 2 a certification?

No. SOC 2 is an attestation and reporting framework. An independent service auditor examines the organization’s controls and issues a SOC 2 report.

5. Is ISO 27001 a certification?

Yes. Organizations can pursue ISO/IEC 27001 certification through an independent certification process. Certification demonstrates conformity with the requirements of the standard.

6. Is SOC 2 mandatory?

SOC 2 is not a general legal requirement. However, customers, partners, or contractual requirements may make a SOC 2 report necessary for doing business.

7. Is ISO 27001 mandatory?

ISO 27001 is not generally a legal requirement. However, specific customers, contracts, industries, or business opportunities may require or strongly prefer ISO 27001 certification.

8. What is the difference between SOC 2 Type I and Type II?

SOC 2 Type I evaluates the design and implementation of controls at a specific point in time. SOC 2 Type II evaluates the design and operating effectiveness of controls over a specified period.

9. Does ISO 27001 cover SOC 2?

No. ISO 27001 does not automatically satisfy SOC 2 requirements. However, many ISO 27001 controls and processes can be mapped to SOC 2 criteria.

10. Does SOC 2 cover ISO 27001?

No. SOC 2 does not automatically satisfy ISO 27001 requirements. Existing SOC 2 controls can, however, provide a strong foundation for an ISO 27001 program.

11. Which is better for a SaaS company?

The appropriate choice depends on the SaaS company’s customers, markets, contracts, security maturity, and growth plans. U.S.-focused enterprise SaaS companies often encounter SOC 2 requirements, while companies with international operations may encounter ISO 27001 requirements.

12. Can SOC 2 and ISO 27001 be completed together?

Yes. Organizations can pursue both concurrently. A common control framework, centralized evidence management, and control mapping can help reduce duplicated work.

What’s The Final Takeaway?

The SOC 2 vs. ISO 27001 decision isn’t really about picking a winner. It’s about understanding what your business needs now and where it is headed next. If enterprise customers are asking for SOC 2, that requirement should factor heavily into your roadmap. If international customers are asking for ISO 27001 certification, that may shape your priorities differently. And if both are likely to matter, don’t build two compliance programs.

Build one strong security foundation and map it across the frameworks you need.

That’s the difference between treating compliance as a series of audits and building a security program that can scale with your business.

With Accorian’s cybersecurity expertise and GORICO’s AI-powered continuous compliance capabilities, organizations can move beyond fragmented compliance workflows toward a unified, continuously managed approach to security and compliance.
