The Short Answer
What is SOC 2 and do you need it?
SOC 2 is an attestation framework published by the AICPA (American Institute of Certified Public Accountants). A licensed CPA firm examines your controls against the Trust Service Criteria — Security is mandatory, while Availability, Confidentiality, Processing Integrity, and Privacy are added based on what you promise customers. The output is not a certificate but an attestation report containing the auditor's opinion, your system description, and control-by-control test results. A Type I report assesses whether controls are suitably designed at a point in time; a Type II report tests whether they operated effectively over an observation window of 3–12 months — which is why US enterprise buyers almost always ask for Type II.
You need SOC 2 if you are a SaaS or cloud-hosted company selling to US enterprises or mid-market buyers. It is the de facto gate in American procurement: security questionnaires, vendor risk reviews, and enterprise contracts routinely stall without a current report. Indian development centres and global teams serving US customers face the same requirement. If your buyers are primarily in Europe or Asia, weigh SOC 2 vs ISO 27001 before committing — many companies eventually carry both.
Realistic timelines: 3–6 months for Type I and 6–12 months for Type II, including the observation window. In India, budget ₹2–4 lakh for SOC 2 consulting and audit-readiness, with the CPA firm's attestation fee separate and indicative. TCSA has delivered 500+ audits and 250+ SOC 2 attestations to date — review our proof of work or compare the top SOC 2 consulting firms in India before choosing a partner.

SOC 2 Frequently Asked Questions
Direct answers from auditors who have delivered 250+ SOC 2 attestations.
How much does SOC 2 cost in India?
SOC 2 consulting and audit-readiness typically costs ₹2–4 lakh in India, depending on scope, company size, and how many Trust Service Criteria you include beyond Security. The licensed CPA firm’s attestation fee is separate and indicative — it varies by auditor, report type (Type I vs Type II), and observation period. Budget both lines before you start.
What is the difference between SOC 2 Type I and Type II?
A Type I report attests that your controls are suitably designed at a single point in time. A Type II report attests that those controls operated effectively over an observation window, typically 3–12 months. Type II carries far more weight with US enterprise buyers; most companies issue a Type I first to unblock deals, then roll straight into the Type II observation period.
How long does SOC 2 take?
Plan for 3–6 months to a Type I report and 6–12 months to a Type II, including the observation window. The work splits into gap assessment and remediation (6–12 weeks), the observation period (3–6 months minimum for a first Type II), and CPA fieldwork plus reporting (4–8 weeks).
Who performs the SOC 2 attestation?
Only a licensed CPA firm can issue a SOC 2 report, under AICPA attestation standards (SSAE 18 / AT-C 105 and 205). Consultants like TCSA handle readiness — scoping, control design, policies, and evidence — and coordinate with the independent CPA firm that performs the examination and signs the opinion. Be wary of any vendor claiming to both prepare you and attest you.
Should I choose SOC 2 or ISO 27001?
Choose SOC 2 if your buyers are US enterprises; choose ISO 27001 if they sit in Europe, Asia, or the Middle East. SOC 2 produces an attestation report from a CPA firm, while ISO 27001 produces a certificate valid for 3 years. The control sets overlap substantially, so many companies implement once and obtain both within the same 12 months.
Does SOC 2 need to be renewed every year?
Effectively, yes. A Type II report covers a defined period, and customers expect a current report with no coverage gaps — so companies run back-to-back 12-month observation windows and issue a fresh Type II annually. Treat SOC 2 as an annual operating cycle, not a one-off project.
