Singapore SaaS compliance: the practical checklist

PDPA first (it's the law), then whichever certification your largest-value buyer asks for — typically SOC 2 for US pipelines, ISO 27001 for EU/APAC, or Cyber Trust for SG enterprise and government.

Yes. SOC 2 Security TSC and PDPA Protection Obligation share most technical controls. One evidence set covers both; the PDPA deltas are consent capture, DPO contact publishing and the 3-day PDPC breach runbook.

The PDPA requires designating a DPO and publishing their business contact information. The DPO can be internal or external and does not need to be based in Singapore. For most startups, a shared or outsourced DPO is sufficient.

For a 10–50 person SaaS with modern cloud infrastructure already in place: PDPA foundations and Cyber Essentials in 4–8 weeks, SOC 2 Type 1 in 30 days (parallel), and the SOC 2 Type 2 observation window begins immediately. First Type 2 report lands around month 5–6.

The PDPA baseline and Cyber Essentials — yes, with a readiness platform and a part-time compliance owner on retainer. Full ISO 27001 or SOC 2 Type 2 benefits from a dedicated compliance owner at least part-time, plus a technical lead to run integrations. LowerPlane includes a dedicated advisor to cover the gap.

LowerPlane Starter ($4,995/year) + CSA Cyber Essentials with first-cert funding + a part-time outsourced DPO is a realistic sub-S$10,000 first-year stack for a 1–20 person SG SaaS. SOC 2 adds the CPA audit fee (US$10,000–15,000). ISO 27001 adds the CB audit fee (quote-based).

A platform covers the implementation evidence and most policy templates. Legal counsel helps on three things: cross-border transfer clauses in your contracts (PDPA Transfer Limitation), MAS-driven FI vendor agreements, and bespoke customer-facing BAAs or MSAs. For most startups, a 2–4 hour legal review per quarter is sufficient.
