FAQ

How long does an ISO 27001 audit take for an ecommerce business?

Typically, Stage 1 audits take 1-2 days, while Stage 2 audits require 2-5 days depending on your organization’s size and complexity. Ecommerce businesses often need additional time due to the complexity of their technology infrastructure and third-party integrations.

Certification costs vary widely based on company size, ranging from $15,000-$50,000 annually including audit fees, consultant costs, and internal resources. However, the investment often pays for itself through increased customer trust and reduced security incident costs.
