Operational Risks:

Service disruptions affecting customer campaigns
Data loss or corruption
Unauthorized system modifications

Third-Party Risks:

Vendor security failures
API vulnerabilities
Integration security gaps

Creating Your Statement of Applicability (SoA)

Your SoA documents which ISO 27001 controls apply to your organization and how you’ll implement them. For marketing software companies, pay special attention to:

A.8.2 Data Classification: Implement clear data classification for different types of marketing data
A.9.4 System Access Management: Control access to customer data and analytics
A.12.6 Management of Technical Vulnerabilities: Regular security testing of your platform
A.13.2 Information Transfer: Secure data exchange with marketing platforms
