Is ISO 27001 mandatory?

No, it's voluntary. But it's routinely a contractual requirement from enterprise and government buyers, especially outside North America. If your deals are stalling on security review, treat it as effectively mandatory.

How long does ISO 27001 certification take?

Manually, 6–12 months. With a consultant, 3–6 months. With automation, well-prepared companies can be audit-ready in 6–8 weeks.

How is ISO 27001 different from SOC 2?

ISO 27001 is a global certification of your entire ISMS, issued after a two-stage audit; SOC 2 is a US-centric attestation report written by a CPA firm against the Trust Services Criteria. Roughly 70% of the underlying controls overlap. Many companies build one program and map it to both.

What's new in ISO 27001:2022?

Annex A was restructured from 114 controls across 14 domains to 93 controls across 4 themes, with 11 new controls added (covering areas like cloud security, threat intelligence, and data leakage prevention). The 2013 version was formally retired on October 31, 2025.

How often are surveillance audits?

Annually, in years 1 and 2 of your 3-year certification cycle, with a full recertification audit in year 3.

Do startups really need ISO 27001?

If you're selling to enterprise or government buyers, increasingly yes — it's one of the fastest ways to shorten or bypass lengthy security questionnaires. For very early-stage teams with no enterprise pipeline, it's often premature.

How much does ISO 27001 actually cost?

For small to mid-size companies, total program cost typically ranges from $15,000 to $50,000+, depending on scope, certification body, and how much of the work is automated.

Is my ISO 27001 certificate still valid if it was issued under the 2013 version?

No. The transition period ended October 31, 2025. Any certificate still on the 2013 version has expired and requires a full initial audit against ISO/IEC 27001:2022.

MetricStream is enterprise GRC software for global banks, pharmaceutical companies, and regulated industries where risk management is a department, not a side task.
