Frequently Asked Questions
How much does ISO 27001 compliance cost on average?
$142k per year is the cross-industry average for ISO 27001 compliance, covering ISMS implementation, internal labour, certification body fees, and tooling. Costs range from $85k (SaaS) to $210k (Financial Services).
How long does ISO 27001 implementation take?
Typically 9–18 months for initial certification. Organisations with existing security programmes or PCI DSS compliance can reduce this to 6–9 months due to significant control overlap between the frameworks.
What does ISO 27001 maturity mean?
ISO 27001 maturity (scored 0–100) reflects how effectively an organisation has operationalised its Information Security Management System. Dimensions include risk assessment coverage, control effectiveness, evidence quality, and continuous improvement processes.
How does ISO 27001 differ from PCI DSS?
ISO 27001 is a risk-based framework covering all information security across an organisation, while PCI DSS is a prescriptive standard focused specifically on payment card data protection. Approximately 40% of ISO 27001 controls directly map to PCI DSS requirements, making dual compliance more efficient.
