SOC 2 or ISO 27001, for an Indian company
Follow your pipeline, not the frameworks. If American enterprise buyers are blocking deals, get SOC 2, because roughly nine in ten US enterprise security questionnaires ask for it by name and most large American companies require a Type 2 report from software vendors in procurement. If you sell to Indian enterprise, European or UK customers, or into government, get ISO 27001, because that is what appears in those RFPs. If you genuinely sell into both, start with the one blocking revenue now and add the second afterwards, which is considerably cheaper than the first because the controls overlap heavily.
What is actually being compared
- SOC 2
- An attestation report written by a licensed CPA firm about whether your controls were designed well and, for a Type 2, whether they actually operated over a period. American in origin and expectation.
- ISO 27001
- An international certification, issued by an accredited body, that your information security management system meets the standard. Recognised globally and named by default in Indian, European and government procurement.
- Both
- Common for companies selling into both markets. The second is much cheaper than the first, because the underlying controls and evidence largely serve both.
How they differ in practice
| Feature | Feature | SOC 2 | ISO 27001 | Both |
|---|---|---|---|---|
What you receive | A report containing an auditor opinion | A certificate, plus the audit report behind it | Both, usually a year or more apart | |
Who issues it | A licensed CPA firm | An accredited certification body | Two separate providers | |
Pass or fail | Neither. Exceptions are written into the report your customers read | Yes. Major nonconformities must be closed before the certificate issues | Both models apply | |
What is assessed | Controls you defined, against the Trust Services Criteria | A management system, against clauses 4 to 10, with Annex A controls selected by risk | Shared controls, assessed two ways | |
Who asks for it | US enterprise buyers, overwhelmingly | Indian enterprise, EU and UK buyers, government procurement | Pipelines spanning both | |
Time driver | The Type 2 observation window, which cannot be compressed | The operating period, plus Stage 1 and Stage 2 | Sequential, not parallel | |
Validity | A report covering a stated period, renewed annually | Three years, with annual surveillance audits | Two renewal cycles to maintain | |
Scope visible to buyers | Described inside the report | Printed on the certificate, so prospects read the boundary | Keep the two scopes aligned | |
Can your implementer also certify | No, the CPA firm must be independent | No, the certification body must be independent of the consultant | No, in both cases | |
Does it satisfy the DPDP Act | No. Helps with Rule 6 safeguards only | No. Helps with Rule 6 safeguards only | No. DPDP remains a separate programme |
Choose SOC 2 if
- Your revenue depends on American enterprise customers, and the requirement is reaching you through their security questionnaires rather than through your own strategy.
- A named deal is blocked right now and the buyer asked for SOC 2 specifically. Buyers who ask for SOC 2 rarely accept ISO 27001 instead, whatever the technical equivalence.
- You want the shortest credible path to unblocking one deal, in which case a Type 1 now with a Type 2 window starting immediately is the usual sequence.
- Your product processes transactions where correctness is the value, which makes the Processing Integrity criterion meaningful rather than decorative.
Choose ISO 27001 if
- You sell to Indian enterprise, European or UK customers, or you tender for government work. ISO 27001 is what those RFPs name, and a SOC 2 report frequently will not be accepted in its place.
- You want something with a defined lifecycle that forces the system to keep running. A three year certificate with annual surveillance audits creates an ongoing obligation that a report does not.
- You want a management system rather than a control attestation, meaning a defined scope, a real risk assessment, an internal audit programme and a management review. That structure is more useful internally.
- Your customers are spread across several regions and you want one credential most of them recognise, which ISO does better than SOC 2 outside North America.
Do both if
- Your pipeline genuinely spans North America and Europe or Indian enterprise, and you are losing deals in both directions for different reasons.
- You already hold one and the second is being asked for repeatedly. The overlap in access management, change management, logging, incident response, vendor management and continuity makes the second materially cheaper.
- Do them in sequence, not in parallel. Running two first-time programmes at once reliably produces two mediocre outcomes, and the evidence discipline built in the first makes the second straightforward.
When the other option is right
If nobody has actually asked you for either, do not buy one yet. Certification pursued speculatively is expensive, and the money is almost always better spent on the underlying controls, MFA everywhere, working offboarding, tested backups, logging that goes back far enough, which is what makes the eventual certification cheap and what reduces your real risk in the meantime. We would rather do that work with you now and the certification later, when a customer has actually named it. Equally, if your driver is the DPDP Act rather than a customer, neither framework discharges it and you should start with the statutory obligations instead.
Whichever you choose, do these first
- Read the last three security questionnaires you received and note which framework they named. That is better evidence about your market than any general advice, including this page.
- Fix MFA coverage and, more importantly, the exception list. Every framework asks about it, every auditor tests it, and it is the cheapest risk reduction available.
- Make offboarding real and evidenced. Access removed on the day, recorded, including SaaS tools outside your identity provider. This is where auditors most reliably find exceptions.
- Extend log retention now, whichever framework you pick. It only evidences a period after that period has passed, so it is the one thing you cannot accelerate later, and DPDP Rule 6 expects a year regardless.
- Start a quarterly access review and keep the records. Both frameworks ask for it, and a sample of one is the single most requested artefact in customer security reviews.
- Decide the scope before you talk to auditors or certification bodies. It drives effort, duration and fee for both, and it is the one decision you cannot easily change later.
