Why US Insurance Underwriters Require SOC 2 and ISO 27001

Cyber insurance underwriting in the United States has become increasingly focused on the security controls a business has in place, how those controls operate, and what evidence the organization can provide. As cyber incidents can create significant financial, operational, legal, and reputational consequences, insurers need information that allows them to evaluate the risks associated with a policy.

This is where SOC 2 and ISO 27001 cyber insurance underwriting discussions often begin.

SOC 2 provides an independent examination of controls relevant to areas such as security, availability, processing integrity, confidentiality, and privacy, depending on the scope and criteria selected. The American Institute of CPAs (AICPA) defines SOC 2 as an examination of controls at a service organization relevant to these Trust Services Criteria.

ISO/IEC 27001, meanwhile, specifies requirements for an Information Security Management System (ISMS) and uses a risk-based approach to information security. Certification can provide independent evidence that an organization's ISMS has been evaluated against the standard's requirements.

Neither SOC 2 nor ISO 27001 automatically qualifies a company for cyber insurance. Insurance carriers establish their own underwriting criteria, application requirements, policy terms, exclusions, limits, deductibles, and pricing considerations.

The value of these frameworks in underwriting is therefore best understood as evidence of an organization's information security practices, rather than as an automatic insurance qualification.

Why Cyber Insurance Underwriting Has Become More Rigorous

Cyber insurance underwriting involves evaluating the potential exposure associated with a business's technology environment, information assets, operations, third parties, and security practices.

The information requested by an insurer can vary significantly based on the organization, industry, revenue, data handled, technology environment, prior incidents, requested coverage, and insurer.

Rising Cybersecurity and Ransomware Risks

Cyber incidents can affect organizations through data breaches, ransomware, business interruption, fraud, system compromise, and third-party incidents.

For insurers, these events can translate into claims involving incident response, legal services, forensic investigations, notification expenses, business interruption, restoration costs, and liability.

This makes the security posture of an applicant relevant during underwriting. An insurer may want to understand whether the organization has controls that reduce exposure to common attack paths and whether the business has established processes for responding to disruptive events.

The Federal Trade Commission notes that businesses considering cyber insurance should evaluate the scope of coverage, including whether policies address different types of cyberattacks and risks involving vendors and third parties.

How Security Controls Influence Cyber Risk Evaluation

Security controls can affect how an insurer understands an organization's cyber risk.

Controls such as multi-factor authentication, privileged access management, endpoint protection, vulnerability management, backups, encryption, incident response, and third-party risk processes may appear in cyber insurance questionnaires or underwriting discussions.

The exact controls requested vary by insurer and policy. A business should therefore avoid assuming that having one recognized security framework means every underwriting requirement has been satisfied.

Why Cyber Insurance Applications Ask Detailed Security Questions

Cyber insurance applications often ask detailed questions because an insurer needs information about the systems, processes, data, and security measures associated with the proposed coverage.

Questions may address:

• Multi-factor authentication
• Privileged accounts
• Remote access
• Endpoint security
• Backup practices
• Vulnerability management
• Security testing
• Incident response
• Data encryption
• Employee security awareness
• Vendor security
• Previous cyber incidents
• Claims history

The objective is to establish a clearer picture of the organization's exposure before the insurer determines applicable policy terms.

The Role of Third-Party and Supply Chain Risk

Modern businesses frequently depend on cloud providers, software vendors, managed service providers, payment platforms, contractors, and other external organizations.

A security incident involving a third party can create consequences for the insured organization even when its own infrastructure was not directly compromised.

As a result, cyber insurance underwriting can include questions about vendor selection, contractual requirements, security reviews, monitoring, access privileges, and incident notification.

What US Cyber Insurance Underwriters Look for Before Issuing a Policy

There is no single universal checklist used by every US cyber insurer. However, recurring areas of inquiry often relate to identity security, endpoint protection, resilience, vulnerability management, incident response, data protection, and third-party risk.

Multi-Factor Authentication and Access Controls

Multi-factor authentication adds an additional verification factor beyond a password. Insurers may ask whether MFA is enabled for remote access, privileged accounts, cloud applications, email, and other sensitive systems.

Questions may also address:

• Privileged account management
• Password policies
• User access reviews
• Administrative access
• Remote access
• Access termination procedures

The scope of MFA coverage can matter. Having MFA enabled for some users does not necessarily mean every relevant system or privileged account is protected.

Endpoint Detection and Response

Endpoint security can be important because compromised laptops, desktops, servers, and other devices can provide attackers with an entry point into an organization's environment.

An insurer may ask whether the organization uses endpoint detection and response technology, anti-malware controls, centralized monitoring, device management, or other endpoint security measures.

The exact technologies accepted by an insurer can vary.

Backup and Recovery Controls

Backups are particularly relevant to ransomware and destructive attacks.

Underwriters may ask about:

• Backup frequency
• Backup locations
• Offline or isolated backups
• Encryption
• Access controls
• Backup testing
• Recovery procedures
• Recovery time objectives

Simply having backups does not necessarily demonstrate that an organization can recover effectively. Evidence that restoration processes are tested can provide additional context about operational resilience.

Vulnerability and Patch Management

Unpatched software and known vulnerabilities can increase exposure to cyberattacks.

Cyber insurance questionnaires may therefore ask about vulnerability scanning, patching schedules, risk prioritization, unsupported software, and remediation timelines.

Organizations may also be asked whether critical vulnerabilities are tracked and whether exceptions are formally reviewed.

Incident Response and Business Continuity

Insurers may want to understand how a business would respond to a cyber incident.

Relevant areas can include:

• Incident response plans
• Roles and responsibilities
• Escalation procedures
• Communication processes
• Recovery priorities
• Business continuity planning
• Disaster recovery
• Incident response exercises

These areas provide context about how an organization intends to manage operational disruption following a security event.

Security Awareness and Employee Training

Employees can be exposed to phishing, credential theft, social engineering, and other attack techniques.

Cyber insurance questionnaires may therefore ask whether employees receive security awareness training and whether the organization provides additional training for users with elevated privileges or specialized responsibilities.

Data Encryption and Protection

Encryption can reduce the risk associated with unauthorized access to certain types of information, depending on how and where it is applied.

Underwriters may ask about encryption for data at rest, data in transit, databases, portable devices, backups, and other sensitive environments.

Data classification and access controls may also form part of the broader discussion.

Third-Party Risk Management

A company's cyber risk does not necessarily stop at its own network.

Insurers may ask how an organization evaluates technology providers and other third parties that access sensitive data or critical systems.

Questions can involve vendor security requirements, contractual provisions, access restrictions, monitoring, and incident notification procedures.

Why SOC 2 Matters in Cyber Insurance Underwriting

SOC 2 can provide useful evidence for organizations that need to demonstrate how security controls operate within a defined system and service environment.

A critical distinction is that SOC 2 is not an ISO-style certification. It is an examination and reporting framework developed by the AICPA based on the Trust Services Criteria.

What SOC 2 Tells an Insurance Underwriter

A SOC 2 report can provide information about controls relevant to the specific system and services included within the report's scope.

Depending on the engagement, the Trust Services Criteria can address:

• Security

• Availability

• Processing integrity

• Confidentiality

• Privacy

Not every SOC 2 engagement includes all five categories. Security is the common criterion, while the additional categories depend on the engagement's scope.

This distinction matters when an insurer reviews a SOC 2 report. The underwriter needs to understand exactly what systems, services, locations, controls, and criteria were included.

SOC 2 Controls Relevant to Cyber Risk

SOC 2 security controls can relate to areas such as access restrictions, logical security, system monitoring, change management, risk management, incident response, and other security-related activities.

The relevance of a particular control depends on the organization's system description and the applicable Trust Services Criteria.

For cyber insurance underwriting, this can provide more detailed evidence than simply stating that a company has a cybersecurity policy.

How SOC 2 Reports Can Provide Security Evidence

A SOC 2 report can contain information about the service organization's system and the controls examined.

A Type 2 SOC 2 report also addresses the operating effectiveness of specified controls over a period of time, rather than only describing their design at a particular point.

This can be relevant when an insurer wants evidence that controls have operated over time.

However, a SOC 2 report has a defined scope and period. It should not be interpreted as proof that every part of an organization or every security control is effective.

SOC 2 and Cyber Insurance Security Questionnaires

A SOC 2 report may make it easier for a company to substantiate certain answers in an insurance questionnaire because the report contains independently examined information about relevant controls.

It does not eliminate the need to complete the insurer's questionnaire accurately.

An insurer may ask questions that fall outside the SOC 2 scope, particularly around claims history, coverage-specific controls, ransomware exposure, business continuity, policy requirements, or specific technologies.

Why ISO 27001 Matters in Cyber Insurance Underwriting

ISO/IEC 27001 provides requirements for an Information Security Management System and uses a risk-based approach to managing information security.

ISO states that the standard is designed for organizations of different sizes and sectors and provides requirements for an ISMS that addresses information security risks.

What ISO 27001 Demonstrates to Cyber Insurers

An ISO/IEC 27001 certificate can demonstrate that an organization's defined ISMS has been evaluated against the requirements of the standard by a certification body.

This can provide useful external evidence of a structured information security management approach.

However, the certificate has a defined scope. The scope should be compared with the systems, locations, services, and business activities being insured.

ISO 27001 Risk Management and Security Controls

ISO/IEC 27001 places risk management at the center of the ISMS.

The organization determines information security risks and establishes controls appropriate to its circumstances.

This risk-based structure can cover areas such as:

• Information security policies

• Asset management

• Access control

• Cryptography

• Physical security

• Operations security

• Communications security

• Supplier relationships

• Incident management

• Business continuity

• Compliance

The precise controls applicable to an organization depend on its risk treatment and Statement of Applicability.

How ISO 27001 Supports Underwriting Evidence

An ISO 27001 certificate can provide an insurer with external evidence that an organization operates an ISMS within the certified scope.

Additional records may still be requested during underwriting.

For example, an insurer may want details about MFA, ransomware protection, backup testing, endpoint controls, claims history, or other specific requirements that are not established merely by presenting an ISO 27001 certificate.

ISO 27001 and Cyber Insurance Risk Assessments

ISO 27001 and cyber insurance underwriting address related but different questions.

ISO 27001 focuses on an organization's information security management system and risk treatment.

Cyber insurance underwriting focuses on the risk associated with providing insurance coverage under particular policy terms.

Because the objectives differ, ISO 27001 certification does not replace the insurer's underwriting process.

SOC 2 vs ISO 27001 for Cyber Insurance

SOC 2 and ISO 27001 can both provide valuable information about information security, but they are structured differently.

Differences in Scope and Assurance

SOC 2 is an AICPA reporting framework focused on controls relevant to selected Trust Services Criteria within a defined system and service environment.

ISO/IEC 27001 is an international standard containing requirements for an ISMS. Organizations can pursue certification through a certification body.

For an insurer, the practical question is not simply whether a company has SOC 2 or ISO 27001. The insurer may also examine the scope, dates, systems, services, findings, exceptions, and relevance of the evidence.

SOC 2 Controls Relevant to Cyber Insurance

SOC 2 can provide evidence concerning security and other selected Trust Services Criteria.

For technology and SaaS companies, the report can be particularly relevant where the insured operates services that process or store customer information.

The report's scope remains critical. A SOC 2 report covering one service may not represent the controls surrounding another system or business unit.

ISO 27001 Risk-Based Information Security Management

ISO/IEC 27001 provides an ISMS structure that connects organizational context, information security risks, controls, monitoring, and continual improvement.

This broader management-system approach can be useful for organizations seeking to demonstrate that information security is managed systematically across a defined scope.

Can Organizations Use SOC 2 and ISO 27001 Together?

Yes.

Organizations can maintain both SOC 2 and ISO/IEC 27001 when their customer, regulatory, contractual, or business requirements justify having both.

The frameworks can address overlapping security areas while providing different forms of evidence.

For example, ISO 27001 can demonstrate a certified ISMS within a defined scope, while SOC 2 can provide an examination report concerning controls for a defined service environment.

How SOC 2 and ISO 27001 Address Common Cyber Insurance Controls

The two frameworks can overlap with many security areas commonly discussed during cyber insurance underwriting.

Access Control and Multi-Factor Authentication

Access management is relevant to both information security frameworks and cyber insurance questionnaires.

An insurer may specifically ask whether MFA covers privileged accounts, remote access, email, cloud systems, or other critical services.

The existence of a framework does not mean every MFA requirement of a particular insurer has automatically been satisfied.

Vulnerability and Security Management

Organizations can use structured security management processes to identify and address vulnerabilities.

Insurance questionnaires may go further by asking about scanning frequency, remediation timelines, critical vulnerabilities, unsupported systems, and external penetration testing.

Incident Detection and Response

Incident management is relevant to information security and cyber insurance.

An insurer may want evidence that the organization has defined procedures for identifying, escalating, containing, and recovering from incidents.

SOC 2 or ISO 27001 evidence can provide useful context, but insurer-specific questions may still need separate answers.

Backup and Business Continuity

Backups and continuity planning are important when considering the potential business impact of ransomware or system disruption.

Organizations may need to demonstrate not only that backups exist but also how they are protected, who can access them, and whether restoration has been tested.

Data Protection and Encryption

Both SOC 2 and ISO 27001 can address security controls associated with protecting information.

For insurance purposes, organizations should understand which data is covered, where it is stored, how it is transmitted, and what encryption mechanisms apply.

Vendor and Third-Party Risk Management

Supplier security is increasingly relevant to organizations that rely on cloud infrastructure and external service providers.

Both SOC 2 and ISO 27001 can provide evidence concerning aspects of third-party security, depending on scope and applicable controls.

An insurer may still ask separate questions about specific vendors or critical dependencies.

What Cyber Insurance Security Questionnaires Typically Ask

Cyber insurance security questionnaires can vary considerably between insurers and policy types. There is no single universal questionnaire.

However, common areas include the following.

Information Security Governance

Questions may cover:

• Security policies

• Responsible security personnel

• Risk management

• Security oversight

• Regulatory obligations

• Security program maturity

Identity and Access Management

Common topics include:

• MFA

• Privileged accounts

• Remote access

• Password controls

• User access reviews

• Account termination

Endpoint and Network Security

An insurer may ask about:

• Endpoint protection

• EDR

• Firewalls

• Network segmentation

• Email security

• Intrusion monitoring

Backup and Recovery

Questions can include:

• Backup frequency

• Backup isolation

• Encryption

• Restoration testing

• Recovery procedures

• Business continuity

Incident Response

An insurer may request information about:

• Incident response plans

• Response teams

• Notification procedures

• Tabletop exercises

• Previous incidents

• Recovery processes

Security Testing and Vulnerability Management

This may include questions about:

• Vulnerability scanning

• Penetration testing

• Patch management

• Critical vulnerability remediation

• Security testing frequency

Third-Party Security

Questionnaires can ask whether critical vendors undergo security reviews and what contractual or technical controls apply to third-party access.

Previous Cyber Incidents and Claims History

Insurance underwriting can also consider historical incidents and claims.

Organizations should provide accurate information about previous cyber events and insurance claims based on the insurer's specific questions and requested period.

Does SOC 2 or ISO 27001 Guarantee Cyber Insurance Coverage?

No.Neither SOC 2 nor ISO 27001 guarantees that an insurer will issue a cyber policy.

Why Certification Does Not Automatically Qualify a Business for Coverage

ISO 27001 certification demonstrates conformity within a defined ISMS scope. SOC 2 provides an examination report for defined systems and selected Trust Services Criteria.

Neither one is an insurance product or a substitute for underwriting.

An insurer can consider other factors such as business size, industry, revenue, data exposure, security controls, prior incidents, requested coverage, policy limits, deductibles, exclusions, and claims history.

How Insurers Evaluate Security Controls Beyond Certifications

An insurer may ask questions that go beyond the information contained in a SOC 2 report or ISO 27001 certificate.

For example, the carrier may ask whether MFA is enabled across all privileged accounts, whether backups are isolated, or how quickly critical vulnerabilities are patched.

These questions can be specific to the insurer's underwriting model.

Why Accurate Answers on Cyber Insurance Applications Matter

Insurance applications should reflect the organization's actual security environment.

Statements about MFA, backups, encryption, endpoint protection, incident response, or other controls should be accurate and current.

An organization should not claim that a control exists across its environment when it only applies to a limited system or user group.

How Policy Terms and Underwriting Criteria Vary by Insurer

Cyber insurance policies are not standardized across every carrier.

Coverage terms, exclusions, deductibles, limits, application questions, and underwriting requirements can vary.

Businesses should therefore review the requirements associated with the specific insurer and policy rather than treating SOC 2 or ISO 27001 as a universal qualification.

How SOC 2 and ISO 27001 Can Strengthen a Cyber Insurance Application

SOC 2 and ISO 27001 can provide structured evidence that may be relevant during underwriting.

Providing Independent Evidence of Security Controls

An independently examined SOC 2 report can provide evidence concerning controls within its defined scope.

An ISO 27001 certificate can provide evidence that a defined ISMS has undergone certification against the standard's requirements.

These forms of evidence can give an insurer additional information when evaluating an organization's security environment.

Demonstrating a Structured Security Program

ISO 27001 can demonstrate that information security is managed through a formal ISMS and risk management process.

SOC 2 can provide detailed reporting on controls relevant to specified Trust Services Criteria.

Together, these can provide different perspectives on how security is managed and evidenced.

Making Security Information Easier to Present During Underwriting

A well-maintained SOC 2 report or ISO 27001 certification record can give an organization established evidence to reference when responding to security-related questions.

The company should still review each questionnaire individually because the insurer may request information outside the scope of either framework.

Strengthening Evidence for Customer and Third-Party Risk Reviews

The value of SOC 2 and ISO 27001 can extend beyond insurance.

Enterprise customers, technology partners, procurement teams, and third parties may also request security evidence.

For organizations selling technology services, these frameworks can therefore become part of a broader approach to demonstrating information security practices.

When Should a US Business Consider SOC 2 or ISO 27001 Before Applying for Cyber Insurance?

The timing depends on the organization's business model, customer requirements, risk profile, and commercial objectives.

Businesses Handling Sensitive Customer Data

Organizations processing confidential, personal, financial, healthcare, or other sensitive information may face more extensive security expectations from customers and business partners.

SOC 2 or ISO 27001 may provide relevant evidence depending on the organization's needs and scope.

SaaS and Technology Companies

SaaS businesses frequently store or process customer information and operate cloud-based systems.

SOC 2 is commonly relevant to service organizations that need to demonstrate controls around their systems and services.

ISO 27001 can provide a broader ISMS framework for organizations seeking certification against an international information security standard.

Financial and Professional Services Organizations

Financial and professional services companies may operate with sensitive customer information and significant third-party dependencies.

Their security requirements can involve access control, confidentiality, availability, vendor risk, incident response, and regulatory considerations.

Healthcare and Life Sciences Organizations

Healthcare and life sciences organizations may handle sensitive health or research information.

Security expectations can involve data protection, access management, business continuity, vendor security, and regulatory obligations.

The appropriate framework depends on the organization's environment and business requirements.

Organizations Facing Enterprise Customer Security Requirements

Large customers may require vendors to provide security reports or recognized certifications before entering or renewing commercial relationships.

In these situations, SOC 2 or ISO 27001 may serve commercial objectives in addition to providing information relevant to insurance discussions.

SOC 2 and ISO 27001 for Cyber Insurance: Key Considerations for US Businesses

Organizations considering cyber insurance should look beyond simply obtaining a certificate or report.

Understand the Insurer's Specific Requirements

Review the insurer's application and questionnaire carefully. Determine which security controls are explicitly requested and whether the insurer has requirements concerning MFA, backups, vulnerability management, endpoint protection, incident response, or other areas.

Map Existing Security Controls to Underwriting Questions

Organizations can compare their existing controls with the questions in the cyber insurance application. This can identify areas where additional evidence or clarification may be required.

Maintain Evidence for Security Controls

Evidence may include security policies, access records, vulnerability reports, backup testing records, incident response exercises, security testing results, and relevant SOC 2 or ISO 27001 records.The exact evidence requested will depend on the insurer and application.

Keep Insurance Applications Accurate and Current

Security environments change.Organizations should ensure that statements made during insurance applications accurately reflect the controls operating at the time of application. Changes in technology, remote access, cloud services, acquisitions, vendors, or security controls can affect the information provided to an insurer.

Review Certification Scope Against the Insured Environment

Scope is one of the most important considerations. A SOC 2 report covering a specific service does not necessarily cover every system operated by the company. Likewise, an ISO 27001 certificate applies to its defined certification scope. The organization should compare the scope of its security evidence with the environment being insured.
