For growing businesses, especially SaaS companies and tech providers, strong information security is important.
It enables you to attract and acquire new customers.
It also helps you enter new markets. Two of the most widely recognized frameworks are SOC 2 and ISO 27001.
When evaluating SOC 2 vs. ISO 27001, which standard is right for your organization?
The answer depends on your customers, target markets, security objectives, and existing compliance programme. SOC 2 and ISO 27001 have significant areas of overlap, but they are not interchangeable. They differ in structure, audit approach, certification, scope, and how customers use them to evaluate suppliers.
This guide explains the main differences between SOC 2 and ISO 27001.
It outlines when each option is most appropriate.
It also explains why some organizations choose both.
SOC 2 vs ISO 27001 at a glance
SOC 2 and ISO 27001 both help organizations show they take information security seriously. However, they provide assurance in different ways.
SOC 2 is an attestation framework focused on controls evaluated against the Trust Services Criteria. It ends with a SOC 2 report. Many SaaS companies, tech providers, and organizations serving enterprise customers use it.
ISO 27001 is an international information security standard focused on establishing and continually improving an Information Security Management System (ISMS). Organizations that successfully complete the certification process receive an ISO 27001 certificate.
The key difference is that SOC 2 gives an attestation report.
ISO 27001 certifies an Information Security Management System (ISMS). The two frameworks overlap in many areas, but they are not interchangeable.
What is SOC 2?
SOC 2 (System and Organization Controls 2) is a compliance standard developed by the American Institute of Certified Public Accountants (AICPA). It evaluates controls relating to the Trust Services Criteria.
Security is the core criterion, while organizations can also address:
- Availability
- Processing integrity
- Confidentiality
- Privacy
SOC 2 is particularly common among SaaS companies, cloud providers, technology businesses, and service organizations that need to demonstrate to customers that their systems and data are appropriately protected.
Organizations typically choose between two primary types of SOC 2 examinations:
SOC 2 Type I evaluates whether controls are suitably designed at a particular point in time.
SOC 2 Type II evaluates both the design of controls and their operating effectiveness over a period of time.
For businesses that sell to enterprise customers, SOC 2 Type II offers clear proof of security.
It shows that security controls are documented.
It also shows that these controls work consistently over time.
What is ISO 27001?
ISO/IEC 27001 is a global standard for setting up, running, and improving an Information Security Management System (ISMS).
Instead of concentrating solely on specific controls, ISO 27001 adopts a management-system framework for information security. It incorporates areas such as:
- Information security risk assessment
- Risk treatment
- Security policies and objectives
- Governance and responsibilities
- Internal audits
- Management reviews
- Continual improvement
- Security controls
The current standard is ISO/IEC 27001:2022. Its Annex A contains 93 controls organized across organizational, people, physical, and technological themes.
Organizations seeking certification undergo an audit by an accredited certification body. Successful organizations receive an ISO 27001 certificate.
What is the difference between SOC 2 and ISO 27001?
Although both frameworks address information security, their approaches are different.
1. Attestation vs certification
This is one of the most important differences.
SOC 2 results in an attestation report from an independent CPA firm.
ISO 27001 results in a formal certification issued following an audit by an accredited certification body.
In practical terms, this means that a customer asking for an "ISO 27001 certificate" and a customer asking for a "SOC 2 report" are asking for different forms of assurance.
2. Controls and management systems
SOC 2 is focused on controls evaluated against the selected Trust Services Criteria.
ISO 27001 focuses on the organization’s overall ISMS, including how the organization identifies, treats, monitors, and continually improves security risks.
This makes ISO 27001 particularly valuable for organizations looking to establish a formal, organization-wide information security management programme.
3. Market expectations
SOC 2 is especially common among US-based technology and SaaS companies selling to enterprise customers.
ISO 27001 has broader international recognition and is frequently requested by organizations operating across Europe and other global markets.
However, there is no universal rule. The best framework is often the one your target customers and procurement teams actually request.
4. Audit and reporting
SOC 2 examinations result in a detailed report describing the organization's controls and the auditor's findings.
ISO 27001 follows a certification audit process focused on whether the organization's ISMS meets the requirements of the standard.
For this reason, businesses should not think of SOC 2 and ISO 27001 as competing versions of exactly the same certification.
SOC 2 vs ISO 27001: Do the frameworks overlap?
Yes. There is strong overlap between SOC 2 and ISO 27001 controls. This is especially true for access management and security policies. It also includes risk management and incident response.
It covers change management and supplier management. It includes business continuity and monitoring.This is important for organizations considering both frameworks.
A well-designed information security programme can create evidence and controls that support many compliance requirements.
This avoids the need for separate programmes for each framework.
However, overlap does not mean that achieving one automatically satisfies the other.
ISO 27001 certification does not automatically make you SOC 2 compliant.
A SOC 2 report does not automatically make you ISO 27001 certified.
SOC 2 or ISO 27001: Which should you choose?
The right choice depends largely on your business model and customers.
Choose SOC 2 if:
- You primarily sell B2B SaaS or technology services.
- Your customers are predominantly in the US.
- Enterprise prospects are requesting a SOC 2 report.
- You need to demonstrate that security controls operate effectively.
- SOC 2 is appearing regularly in customer security questionnaires.
Choose ISO 27001 if:
- You operate across international markets.
- European or global customers are requesting ISO 27001.
- You want a formal information security certification.
- You need a structured ISMS and risk-management programme.
- You want security governance to become an integrated part of your organization.
Consider both if:
- You sell to both US and international enterprise customers.
- Different customers request different frameworks.
- You are scaling into new markets.
- Your organization already has a mature security programme.
- You want to maximize assurance and reduce procurement friction.
For many growing businesses, the question shifts from “SOC 2 vs ISO 27001?”
It becomes “How can we build one efficient compliance programme that supports both?”
Can you do SOC 2 and ISO 27001 together?
Yes, because the two frameworks overlap, organizations can often use one shared control environment.
They can also reuse documentation, evidence, policies, risk assessments, and operational processes.
The key is to plan the compliance programme strategically from the beginning.
Instead of creating one set of controls for SOC 2, organizations can map the requirements. They can do the same for ISO 27001.
This avoids creating a separate set of controls for each standard. They can identify shared controls, set clear ownership, and create a centralized evidence process.
This can make achieving and maintaining multiple certifications significantly more manageable.
The important word is managed. Both frameworks require ongoing attention, evidence, monitoring and improvement—not simply a one-time audit project.
SOC 2 vs ISO 27001: What should you do first?
Start with your business requirements, rather than simply choosing the framework that appears most popular.
Ask:
- Which framework are your largest customers requesting?
- Where are your target customers located?
- Are enterprise deals being delayed because you lack a specific certification or report?
- How mature is your information security programme?
- Do you need a formal ISMS?
- Will you eventually need both SOC 2 and ISO 27001?
If most of your immediate sales opportunities are with US enterprise customers, SOC 2 may be the logical starting point.
If international customers are requesting formal security certification, ISO 27001 may be the better starting point.
If both are appearing in your sales pipeline, building a unified compliance programme from the beginning can be more efficient.

FAQs
Is SOC 2 better than ISO 27001?
Neither is universally better. SOC 2 may be best for organizations with US enterprise customers who ask for a SOC 2 report. ISO 27001 may be best for organizations that want an internationally recognized information security certification.
Can an organization hold both SOC 2 and ISO 27001?
Yes, it can. Many organizations pursue both. Because the frameworks overlap in many ways, a well-designed security and compliance programme can support both. It can do this without creating two separate systems.
Is ISO 27001 equivalent to SOC 2?
No. They address many similar information security concerns but are different frameworks. ISO 27001 certifies an Information Security Management System, while SOC 2 provides an independent attestation report against the selected Trust Services Criteria.
Which is easier: SOC 2 or ISO 27001?
There is no universal answer. The complexity depends on your organization's size, existing controls, scope, documentation, risk management processes and audit readiness. The appropriate choice should also consider what your customers require.
Do I need SOC 2 if I have ISO 27001?
Possibly. ISO 27001 certification does not automatically satisfy a customer that specifically requires a SOC 2 report. If important customers or prospects request SOC 2, you may still need to pursue it.
Do I need ISO 27001 if I have SOC 2?
Not necessarily. However, customers, partners or procurement teams may specifically require ISO 27001 certification, particularly in international markets. Your customer requirements should guide the decision.
How long does SOC 2 or ISO 27001 take?
The timeline varies considerably depending on the organization's size, scope, existing security controls, documentation and readiness. SOC 2 also needs proof that controls ran over a set period. ISO 27001 focuses on setting up and auditing an ISMS.
How can I prepare for both SOC 2 and ISO 27001?
Start by assessing your current security and compliance posture. Identify common controls, establish an ISMS and risk-management process, assign control owners, document policies and procedures, and create a repeatable evidence-collection process. A managed audit service can help coordinate these activities and maintain ongoing audit readiness.
