The deal-blocking problem
For Indian SaaS companies selling into the US and global enterprise market, a security attestation is frequently the difference between winning and losing. Procurement teams ask for SOC 2 — usually Type II — before signing, and enterprise security questionnaires assume ISO 27001 or an equivalent ISMS. Deals stall in the security-review stage for want of these.
SOC 2 vs ISO 27001 — which, and when
SOC 2
An AICPA attestation against the Trust Services Criteria (Security plus optionally Availability, Confidentiality, Processing Integrity, Privacy). Type I assesses control design at a point in time; Type II tests operating effectiveness over 3–12 months. US enterprise buyers overwhelmingly want Type II.
ISO 27001
An internationally-recognised certification of a working Information Security Management System (ISMS). Global and Indian enterprise procurement, and many regulated markets, ask for it first. ISO 27001:2022 restructured the earlier 114 controls into 93 across four themes.
The decision
Selling primarily to US enterprises → SOC 2 Type II. Selling globally or into regulated/enterprise procurement → ISO 27001. Most scaling SaaS companies end up needing both.
The doing-both-together advantage
The control overlap between SOC 2 and ISO 27001 is large — access control, change management, risk assessment, incident response, vendor management. Building one ISMS and mapping shared requirements once lets you evidence both from a single control set, which is materially cheaper and faster than two sequential projects.
Timelines and cost
- SOC 2 Type I readiness: typically 6–10 weeks for a mid-size SaaS team.
- SOC 2 Type II: add the observation window your customers require (commonly 3–6 months for a first report).
- ISO 27001: typically 3–6 months to certification-ready, plus the certification body's audit scheduling.
- Indian delivery is typically well below US-only providers for the same AICPA-standard SOC 2 outcome.
Recommendations for Indian SaaS founders
- Start when the first enterprise deal enters security review — not after it stalls.
- Choose the attestation your actual buyers demand, then add the second from the same ISMS.
- Set up evidence collection from day one — Type II tests controls over months.
- Use senior assessors who understand modern SaaS architecture (API, cloud, multi-tenant).
