ISO 27001 certification cost in India is about ₹2 to ₹4 lakh in year one for a typical company of 10 to 100 people, according to one consultancy, but other published guides quote far higher. The gap comes from what each source counts: consulting, gap analysis, tools, training, internal audits and the certification body’s fee. Set your scope first, then compare quotes on that scope.
The short version:
- Year-one cost for 10 to 200 employees is ₹1.7 to ₹4.5 lakh in one provider’s table.
- The certification body’s audit fee is about ₹0.8 to ₹1.5 lakh in the same table, and consulting is the bigger line.
- Surveillance audits in years two and three cost about ₹60,000 to ₹80,000 a year, and recertification ₹1.5 to ₹2.5 lakh.
- Another provider quotes ₹8 lakh to ₹40 lakh for small businesses, so verify any figure against a written quote.
ISO 27001 Certification Cost by Company Size
Year-one cost rises with headcount, products and locations. This table shows TCSA’s 2026 estimates. TCSA sells ISO 27001 consulting, so read its numbers as one provider’s view.
| Company size | Consulting | Certification body fee | Year-one total |
| 10 to 50 employees, single product | ₹1 to ₹2 lakh | ₹0.7 to ₹1 lakh | ₹1.7 to ₹3 lakh |
| 50 to 100 employees | ₹2 to ₹2.5 lakh | ₹0.8 to ₹1.2 lakh | ₹2.8 to ₹3.7 lakh |
| 100 to 200 employees, multiple products or locations | ₹2.5 to ₹3 lakh | ₹1 to ₹1.5 lakh | ₹3.5 to ₹4.5 lakh |
| Other firms’ typical quotes (TCSA’s comparison) | ₹4 to ₹8 lakh | ₹1 to ₹2 lakh | ₹5 to ₹10 lakh |
ISO 27001 Audit Cost
The ISO 27001 audit cost is the certification body’s fee, and it is the smallest part of year one for most firms. TCSA puts it at about ₹0.8 to ₹1.2 lakh for a combined Stage 1 and Stage 2 audit.
Surveillance Audits
You are audited again in years two and three. TCSA lists ₹60,000 to ₹80,000 a year.
Recertification
The certificate lasts three years. TCSA lists recertification in year four at ₹1.5 to ₹2.5 lakh. Budget for it from the start.
ISO 27001 Consultant Fees
ISO 27001 consultant fees run from ₹1 to ₹3 lakh in TCSA’s pricing, and other firms quote ₹4 to ₹8 lakh. The fee depends on size, complexity and how much the consultant builds for you.
What the Consultant Does
The work includes scoping, risk assessment, policies, control implementation support, training and audit preparation. ISO 27001 is a risk-based standard, so most of the effort goes into the risk work and the controls you select.
Why Consultant Quotes Vary So Much
One quote may include only documents and a gap analysis. Another may include hands-on control implementation, training and audit support. Ask for a deliverables list before you compare totals.
Other ISO 27001 Costs to Budget For
Tools and internal time are the costs most quotes leave out. TCSA lists the following annual items.
| Item | Estimated cost |
| Internal staff time | ₹90,000 to ₹1.3 lakh (at ₹2,000 an hour) |
| Password manager | ₹15,000 a year |
| Endpoint protection, if needed | ₹30,000 to ₹50,000 a year |
| Log management or SIEM, optional | ₹50,000 to ₹1 lakh a year |
TCSA’s three-year total cost of ownership is ₹4 to ₹6.5 lakh. It does not price penetration testing or separate training, so ask your provider whether those are inside the quote.
Why Published ISO 27001 Figures Differ So Much
The same standard shows prices that differ by up to ten times because sources count different things. Vinsys states ₹8 to ₹40 lakh for small businesses, built from separate lines.
| Vinsys component | Range for small businesses |
| Gap analysis | ₹2.5 to ₹8 lakh |
| Implementation | ₹4 to ₹12 lakh |
| Internal audits | ₹4 to ₹12 lakh |
| External certification audit | ₹8 to ₹16 lakh |
| Annual surveillance audit | ₹4 to ₹16 lakh a year |
These figures sit far above TCSA’s, and we found no independent source to settle the difference. Treat both as bookends, and decide with written quotes on your own scope.
What Pushes ISO 27001 Cost Up or Down
The sources name these drivers: the size of your IT environment, the scope (one product or the whole company), existing frameworks such as GDPR, HIPAA or NIST, the use of consultants, and the certification body you pick.
How to Keep ISO 27001 Cost Down
- Narrow the scope. Certify the product or business unit that your customers ask about.
- Reuse what you have. Controls from other frameworks may already cover part of the standard.
- Ask what is excluded. Check tools, training and penetration testing.
- Get the three-year view. Include surveillance audits and the year-four recertification.
- Use an accredited body when buyers require it. Confirm this before you pay.
