FAQ

How often should financial software companies undergo ISO 27001 audits?

ISO 27001 certificates are valid for three years, with annual surveillance audits required. However, financial software companies should conduct internal audits quarterly and may need additional compliance audits for specific regulations like PCI DSS, which requires annual assessments.

What are the most critical controls for financial software ISO 27001 compliance?

The most critical controls include access management (A.9), cryptography (A.10), incident management (A.16), and business continuity (A.17). These directly impact your ability to protect financial data and maintain service availability during security events.

How long does ISO 27001 certification typically take for financial software companies?

The certification process usually takes 6-12 months, depending on your current security maturity level. Financial software companies often require additional time due to complex regulatory requirements and the need for extensive documentation and testing.

Can ISO 27001 certification help with other financial compliance requirements?

Yes, ISO 27001 provides a strong foundation for meeting other compliance requirements like PCI DSS, SOX, and GDPR. Many controls overlap, and having an established ISMS makes additional compliance efforts more efficient.

What happens if we fail the ISO 27001 audit?

If major non-conformities are identified, you’ll receive a detailed report with required corrective actions. You’ll have the opportunity to address these issues and undergo a follow-up audit. Minor non-conformities can typically be resolved within the certification timeline.
