ISO 27001 in India — FAQs

Straight answers to what Indian companies ask us before starting ISO 27001 certification.

How much does ISO 27001 certification cost in India?

ISO 27001 consulting with TCSA costs ₹1–3 Lakh depending on company size, scope, and existing security maturity — fixed and quoted upfront, with no hourly billing. Accredited certification body (CB) audit fees are separate and indicative, typically quoted by the CB based on headcount and number of sites. Be wary of "all-inclusive" quotes that bundle a certificate from a non-accredited body.

How long does ISO 27001 certification take?

Most Indian companies complete the journey in 8–12 weeks with TCSA: gap analysis (1–2 weeks), risk assessment and documentation (4–6 weeks), implementation and internal audit (3–4 weeks), followed by the Stage 1 and Stage 2 certification audits. Larger or multi-site organizations can take longer.

ISO 27001:2022 vs ISO 27001:2013 — which version applies?

ISO 27001:2022 is the current version — all certifications are now issued against it, and the deadline for transitioning old 2013 certificates (31 October 2025) has passed. The 2022 revision restructures Annex A into 93 controls across four themes (organizational, people, physical, technological) and adds controls such as threat intelligence, cloud security, and data leakage prevention. TCSA implements ISO 27001:2022 by default.

Do we really need a consultant for ISO 27001?

Not legally — you can self-implement. In practice, first-time teams underestimate the risk assessment, the Statement of Applicability, and what auditors expect on audit day. A good consultant compresses 6–12 months of trial and error into 8–12 weeks with documentation that auditors accept the first time. TCSA’s track record across 500+ audits is the practical argument.

Who actually issues the ISO 27001 certificate?

An accredited certification body (CB) — not consultants, and not TCSA. Consultants build and prepare your ISMS; an independent CB then conducts the Stage 1 and Stage 2 audits and issues the certificate. Choose a CB accredited by NABCB, UKAS, or another IAF member so your certificate is recognized globally. CB fees are separate from consulting fees.

What are surveillance audits after certification?

An ISO 27001 certificate is valid for three years. Your certification body conducts surveillance audits in years 1 and 2 to confirm the ISMS still operates effectively, followed by a full recertification audit in year 3. TCSA supports surveillance preparation — internal audits, management reviews, and evidence upkeep — so you stay audit-ready year-round.
