Frequently Asked Questions

What is a typical first-time timeline?

Many SMEs need roughly 3–9 months from serious kickoff to Stage 2, depending on scope and starting maturity. Complex multi-site programmes take longer.

Does the 31 October 2025 date still affect new projects?

That IAF MD 26 date was the end of the 2013→2022 transition for certified clients. New projects should implement ISO/IEC 27001:2022 directly.

What happens after the certificate is issued?

Expect annual surveillance and recertification on a typical three-year cycle.
