ISO 27001 in Singapore: SAC-accredited CBs, two-stage audit

Singapore companies obtain ISO 27001 certification from SAC-accredited certification bodies. Build an ISMS, run an internal audit and management review, pass Stage 1 and Stage 2, then run annual surveillance and recertify every three years. Fees are quote-based.

Choosing a SAC-accredited certification body

Certification is granted by third-party CBs accredited by the Singapore Accreditation Council. Request quotes from 2–3 CBs; the SAC directory is the authoritative starting point. Fees are quote-based — scope, headcount, number of sites and complexity drive the final number.

What drives cost

📏

Scope breadth

One product + one cloud account is faster than three products across multiple regions.

👥

Headcount and sites

CB audit effort scales with people and locations.

🛠️

Readiness platform

$4,995–$15,000/yr compliance platform replaces most consultant hours.

🔍

Pen test cadence

Not strictly required by ISO, but most CBs expect an annual internal + external pen test.

EDGE Grant

EnterpriseSG’s EDGE Grant (effective 30 Sep 2026) can cover eligible standards and certification activities for Singapore SMEs — up to 70%, capped at S$100,000 per year, ≥30% local ownership, reimbursement. See Singapore cybersecurity grants.

🔁

Overlap with Cyber Trust and SOC 2

Running ISO 27001 + Cyber Trust yields ~70% overlap; many SG teams schedule both audits within a quarter. ISO 27001 + SOC 2 Security yields ~80%, with the deltas being the Statement of Applicability (ISO) and Trust Services Criteria mapping (SOC 2).

Frequently asked questions

Who issues ISO 27001 certificates in Singapore?

Certification bodies accredited by the Singapore Accreditation Council (SAC). SAC maintains a published directory. A certificate from a SAC-accredited CB carries full international ISO 27001 recognition.

How long does it take?

A typical first certification runs 4–6 months end-to-end for a 10–50 person SaaS: 4–8 weeks of ISMS build and gap closure, Stage 1 audit (documentation review), gap remediation, Stage 2 audit (operating effectiveness). Pre-existing SOC 2 controls shorten the build substantially.

Can EDGE Grant cover it?

EnterpriseSG's EDGE Grant covers eligible activities for Singapore SMEs. Standards certification can qualify under relevant activity codes; eligibility and current scope should be reconfirmed at the EDGE Grant page before applying.

Can I use an overseas certification body?

Yes. ISO 27001 certificates from accredited CBs anywhere in the world are internationally recognised. SG buyers accept certificates from any IAF-recognised accreditation body. SAC-accredited CBs are the local default; teams occasionally pick an overseas CB when the engagement model or pricing is better.

Can we run ISO 27001 and SOC 2 with the same auditor?

No — different firms are required. ISO 27001 is issued by an accredited CB; SOC 2 is issued by an AICPA-licensed CPA firm. A few global firms operate both practices under one brand, but the engagements are legally separate.

How much pen-testing does ISO 27001 require?

The standard does not strictly mandate pen testing, but Annex A.8.8 (technical vulnerability management) requires regular testing, and most CBs expect an annual internal + external pen test plus retesting after significant change. Budget S$8,000–S$20,000 depending on scope.

What headcount do I need to run an ISMS?

A 10–50 person SaaS typically runs the ISMS with a part-time security lead or compliance owner plus the engineering lead. Add a part-time DPO for PDPA alignment. External support (readiness platform, dedicated advisor, independent pen-test firm) covers what the in-house team cannot.

Build the ISMS once, run two audits

LowerPlane maps ISO 27001 Annex A to SOC 2 TSC and Cyber Trust tiers so one evidence pack covers all three.
