ISO 27001 is the certification European, APAC and Middle Eastern buyers ask for, and Indian companies routinely delay it because nobody will give them a number. Published Indian pricing for 2026 puts a typical startup or mid-market company of ten to a hundred employees at ₹2–4 lakh for year one — considerably less than most people assume, and less than the equivalent SOC 2 exercise.
Why quotes appear to vary wildly
The cost arrives as two invoices from two different parties, and conflating them is the source of most confusion.
| Invoice | Range | Covers |
|---|---|---|
| Consultant fees | ₹1 – 3 lakh | Gap assessment, policy documentation, technical implementation support, employee training, internal audit |
| Certification body audit | ₹0.8 – 1.2 lakh | The audit itself, billed separately |
A quote that looks unusually low is almost always one of the two rather than both. Ask explicitly which you are being quoted for.
Cost by company size
| Employees | Consulting | Audit | Year-one total |
|---|---|---|---|
| 10 – 50 | ₹1 – 2 lakh | ₹0.7 – 1 lakh | ₹1.7 – 3 lakh |
| 50 – 100 | ₹2 – 2.5 lakh | ₹0.8 – 1.2 lakh | ₹2.8 – 3.7 lakh |
| 100 – 200 | — | — | ₹3.5 – 4.5 lakh |
The scaling is gentler than headcount would suggest, because the audit assesses your management system rather than your people. Doubling the team does not double the work.
Tooling is optional and frequently oversold
- Password manager — around ₹15,000 a year
- Endpoint protection — ₹30,000 – ₹50,000
- SIEM or log management — ₹50,000 – ₹1,00,000
You do not need all three to certify. Buy what closes an actual gap identified in your assessment, and be wary of a consultant whose recommendation list happens to consist of products they resell.
The cost nobody budgets for
Your own time — roughly ₹90,000 to ₹1,30,000 in blended internal cost, across twenty to fifty hours of team effort.
That is real, and it lands on your most senior people. The evidence an auditor wants — access reviews, risk assessments, incident records — can only be produced by the people who actually run things. It cannot be delegated to whoever has capacity.
The three-year picture
Year one looks worse than the reality, because the certificate is valid for three years.
| When | Cost |
|---|---|
| Year 1 — implementation and certification | ₹2 – 4 lakh |
| Year 2 — surveillance audit | ₹60,000 – 80,000 |
| Year 3 — surveillance audit | ₹60,000 – 80,000 |
| Year 4 — recertification | ₹1.5 – 2.5 lakh |
Three-year total cost of ownership lands at ₹4 to ₹6.5 lakh. On timeline, the standard path is twelve to sixteen weeks from kickoff to certificate, or around eight weeks on a fast track if you already hold SOC 2 or have a genuinely strong existing security posture.
The commercial arithmetic
State it plainly. If one European or Middle Eastern deal is currently stalled on a security questionnaire, the certification costs less than the margin on that single contract — and it removes the objection permanently, for three years, across every subsequent deal.
Companies that treat ISO 27001 as a cost centre are usually the ones who have not counted the deals it would unblock. The question is not what it costs. It is how many conversations you are currently losing at the questionnaire stage.
If you would like a gap assessment before committing to a consultant, we can tell you honestly how far you already are from certifiable.
Frequently asked questions
How long does ISO 27001 certification take in India? +
The standard path is twelve to sixteen weeks from kickoff to certificate. Around eight weeks is achievable on a fast track if you already hold SOC 2 or have a genuinely strong existing security posture.
How long is an ISO 27001 certificate valid for? +
Three years. A surveillance audit falls in year two and again in year three at ₹60,000 to ₹80,000 each, and recertification in year four costs ₹1.5 to ₹2.5 lakh. That is why year one looks worse than the reality.
Is ISO 27001 cheaper than SOC 2 in India? +
Yes. Published Indian pricing for 2026 puts a typical startup or mid-market company of ten to a hundred employees at ₹2 to ₹4 lakh for year one, which is less than the equivalent SOC 2 exercise. It is also considerably less than most people assume.
How much does ISO 27001 cost for a company with 100 to 200 employees? +
Year one comes to ₹3.5 to ₹4.5 lakh for a company of a hundred to two hundred employees. A company of fifty to a hundred pays ₹2.8 to ₹3.7 lakh, and one of ten to fifty pays ₹1.7 to ₹3 lakh. The scaling is gentler than headcount would suggest, because the audit assesses your management system rather than your people.
How much internal time does ISO 27001 take? +
Twenty to fifty hours of team effort, which works out at roughly ₹90,000 to ₹1,30,000 in blended internal cost. It lands on your most senior people, because the evidence an auditor wants — access reviews, risk assessments, incident records — can only be produced by the people who actually run things. It cannot be delegated to whoever has capacity.
What is the total three-year cost of ISO 27001? +
Three-year total cost of ownership lands at ₹4 to ₹6.5 lakh. That covers year one implementation and certification at ₹2 to ₹4 lakh, plus surveillance audits in years two and three at ₹60,000 to ₹80,000 each. Recertification in year four is a further ₹1.5 to ₹2.5 lakh.
