Summary

Marketing software handles some of your organization’s most sensitive assets — customer data, behavioral analytics, campaign strategies, and third-party integrations. If your company uses or develops marketing platforms, understanding the ISO 27001 requirements list is essential for protecting that data and demonstrating trustworthiness to clients and partners. ISO 27001 is structured around mandatory clauses (4–10) and an Annex A of security controls. Both apply to marketing software environments. - A.5.23 – Information Security for Use of Cloud Services: Most marketing software is cloud-based; cloud security policies are mandatory

ISO 27001 Requirements List for Marketing Software: A Complete Compliance Guide

This guide breaks down the specific ISO 27001 controls most relevant to marketing software environments, helping you build a compliant information security management system (ISMS) without wading through hundreds of pages of standards documentation.

What Is ISO 27001 and Why Does It Matter for Marketing Software?

ISO 27001 is the internationally recognized standard for information security management. It provides a framework for identifying risks, implementing controls, and continuously improving your security posture.

For marketing software specifically, ISO 27001 matters because:

Marketing platforms process personal data at scale (email addresses, behavioral data, purchase history)
They often integrate with CRMs, payment systems, and analytics tools, expanding the attack surface
Data breaches in marketing systems can trigger GDPR, CCPA, and other regulatory penalties
Enterprise clients increasingly require ISO 27001 certification before signing contracts

Whether you’re a SaaS vendor building a marketing automation tool or a company using marketing software internally, the requirements apply to your ISMS scope.

The ISO 27001 Requirements List: Core Clauses

ISO 27001 is structured around mandatory clauses (4–10) and an Annex A of security controls. Both apply to marketing software environments.

Clause 4: Context of the Organization

You must define the internal and external factors that affect your ISMS. For marketing software, this includes:

Identifying stakeholders (customers, regulators, marketing agencies, data processors)
Defining the scope of your ISMS — does it cover your entire platform or specific modules handling personal data?
Documenting how marketing data flows across systems and borders

Clause 5: Leadership and Commitment

Top management must demonstrate active involvement in information security. This means:

Appointing an Information Security Officer (ISO) or equivalent
Establishing a formal information security policy that covers marketing data handling
Ensuring security objectives align with business goals

Clause 6: Planning

Risk assessment and treatment are at the heart of ISO 27001. For marketing software, you need to:

Conduct a risk assessment covering threats like data leakage, unauthorized access to customer lists, and API vulnerabilities
Define a risk treatment plan with specific controls for each identified risk
Set measurable information security objectives

Clause 7: Support

This clause covers the resources, competence, and communication needed to maintain your ISMS:

Train marketing and development staff on data handling policies
Maintain documented information (policies, procedures, evidence of controls)
Establish internal and external communication protocols for security incidents

Clause 8: Operation

You must implement and control the processes defined in your planning phase. Key operational requirements include:

Executing your risk treatment plan with documented evidence
Managing third-party supplier risks (ad networks, analytics vendors, CRM integrations)
Maintaining change management procedures for software updates that affect security

Clause 9: Performance Evaluation

Monitoring and measurement ensure your controls are actually working:

Conduct internal audits of your ISMS at planned intervals
Perform management reviews to assess ISMS performance
Track security metrics relevant to marketing software (e.g., failed login attempts, data access logs)

Clause 10: Improvement

When nonconformities occur, you must respond and prevent recurrence:

Document and investigate security incidents involving marketing data
Apply corrective actions and verify their effectiveness
Continuously improve the ISMS based on audit findings and incident data

ISO 27001 Annex A Controls Most Relevant to Marketing Software

Annex A contains 93 controls organized into four themes in the 2022 version of the standard. Here are the controls with the highest relevance to marketing software environments.

Organizational Controls

A.5.1 – Policies for Information Security: Establish a clear policy governing how marketing data is classified, stored, and shared
A.5.19 – Information Security in Supplier Relationships: Assess security risks from email service providers, ad platforms, and analytics tools
A.5.23 – Information Security for Use of Cloud Services: Most marketing software is cloud-based; cloud security policies are mandatory
A.5.34 – Privacy and Protection of PII: Directly addresses personal data handling in marketing contexts

People Controls

A.6.3 – Information Security Awareness, Education, and Training: Marketing teams must understand phishing risks, data handling rules, and acceptable use policies
A.6.5 – Responsibilities After Termination: Revoke access to marketing platforms when employees leave

Physical Controls

A.7.1 – Physical Security Perimeters: Relevant if your marketing software infrastructure runs on-premises or in co-located data centers
A.7.8 – Equipment Siting and Protection: Protects servers storing customer marketing data

Technological Controls

A.8.2 – Privileged Access Rights: Limit who can access customer databases and campaign data within your marketing platform
A.8.5 – Secure Authentication: Enforce MFA for all marketing software admin accounts
A.8.10 – Information Deletion: Implement data retention and deletion policies for expired marketing lists
A.8.11 – Data Masking: Mask personal data in non-production environments used for testing
A.8.12 – Data Leakage Prevention: Deploy DLP tools to prevent unauthorized export of customer data
A.8.24 – Use of Cryptography: Encrypt customer data at rest and in transit within your marketing platform
A.8.25 – Secure Development Lifecycle: If you develop marketing software, integrate security into your SDLC
A.8.28 – Secure Coding: Prevent common vulnerabilities like SQL injection that could expose marketing databases

Building Your Statement of Applicability (SoA) for Marketing Software

The Statement of Applicability is a mandatory document listing all Annex A controls, whether you’ve included or excluded them, and your justification.

For marketing software, your SoA should:

Include all controls related to data protection, access management, and supplier security
Exclude controls that genuinely don’t apply (e.g., physical media controls if you’re fully cloud-based) with documented justification
Map each control to specific risks identified in your risk assessment
Reference supporting policies and procedures for each included control

Common Compliance Gaps in Marketing Software Environments

Many organizations struggle with the same ISO 27001 issues when it comes to marketing platforms:

Unmanaged third-party integrations: Connecting an unapproved analytics tool can introduce significant risk
Excessive access permissions: Marketing staff often have broader database access than their roles require
Inadequate data retention policies: Keeping customer lists indefinitely violates both ISO 27001 and GDPR principles
Missing incident response procedures: No documented process for responding to a marketing database breach
Undocumented API security: APIs connecting marketing tools to CRMs are frequently overlooked in risk assessments

FAQ: ISO 27001 and Marketing Software

Does ISO 27001 certification cover GDPR compliance automatically?

No. ISO 27001 and GDPR have significant overlap, particularly around data protection and risk management, but certification does not guarantee GDPR compliance. ISO 27001 focuses on information security management broadly, while GDPR has specific legal requirements around consent, data subject rights, and breach notification timelines. You’ll need to address GDPR requirements separately, though your ISMS documentation will support your compliance efforts.

Which marketing software vendors are already ISO 27001 certified?

Many enterprise marketing platforms — including HubSpot, Salesforce Marketing Cloud, Mailchimp (Intuit), and Marketo — hold ISO 27001 certification. However, their certification covers their own infrastructure, not your use of their platform. You’re still responsible for how you configure, access, and manage data within those tools.

How long does it take to achieve ISO 27001 certification for a marketing software company?

Most organizations take 6 to 18 months from initial gap assessment to certification audit. The timeline depends on your current security maturity, the complexity of your marketing software environment, and how quickly you can implement required controls and gather evidence.

Do we need ISO 27001 if we only use marketing software internally?

Not necessarily for certification, but the framework is still valuable. If you handle customer personal data through marketing tools, you have legal and ethical obligations to protect it. Many enterprise clients also require their vendors and partners to demonstrate ISO 27001 compliance regardless of whether you’re a software developer or just a user.

What’s the difference between ISO 27001 and SOC 2 for marketing software?

ISO 27001 is an international standard with formal third-party certification. SOC 2 is a US-focused audit report based on the AICPA’s Trust Services Criteria. Both address information security, but ISO 27001 is more prescriptive about building a management system, while SOC 2 focuses on demonstrating operational effectiveness over a period of time. Many marketing software companies pursue both to satisfy different client requirements.
