Evidence & Verification

Proof & Track Record

Every number TCSA publishes — 1,000+ audits, 300+ SOC 2 engagements, zero first-time audit failures, our ratings — is explained and sourced on this one page. For each claim you will find what it counts, where the figure comes from, and how to check it without taking our word for anything.

Last reviewed: June 2026 Figures reflect internal engagement records and public review platforms as of June 2026

Key Takeaways

  • TCSA has delivered 1,000+ audits since 2017, for clients headquartered in India, the US, the UK, Australia and the UAE.
  • 300+ of those engagements are SOC 2 readiness and attestation programs, with zero first-time audit failures across engagements to date — a record of outcomes so far, not a guarantee.
  • Ratings are triangulated from three labeled sources: a 5.0-star Google Business Profile (public client reviews), 5.0/5 on AmbitionBox (3 employee reviews), and 4.9/5 across 150 responses of internal client engagement feedback.
  • Every engagement is led by a named auditor — Surendra Pal Singh, Parth Chauhan, or Saundhi Chauhan — whose credentials are published below. You can meet your auditor before signing.

The numbers, explained

Headline statistics are easy to publish and hard to check. So we apply the standard we hold clients to in audit work: a claim is only as good as what it counts and the record behind it. Here is each number we use, defined.

Each headline claim TCSA publishes, what it counts, and how it is sourced and verified
ClaimWhat it countsSource / verification
1,000+ audits to dateCompleted audit, certification, and compliance engagements across all frameworks — ISO 27001, SOC 2, SOC 1, VAPT, DPDP, and others — for clients in fintech, SaaS, logistics and cargo, staffing, go-to-market (GTM) and sales-tech, healthtech, and AI.Internal engagement records to date.

Independent ratings

A single rating is easy to cherry-pick, so we triangulate three sources and label what each one actually measures. They are different instruments: public client reviews, employee reviews, and our own engagement-close feedback.

The three rating sources TCSA publishes, what each measures, and the sample behind each
SourceWhat it measuresRatingSample
Google Business ProfilePublic client reviews of TCSA, posted by reviewers on their own Google accounts. Fully public — readable without contacting us.5.0★Public reviews. Check the profile directly.
AmbitionBoxEmployee reviews of TCSA as a workplace — a signal of how the firm treats its own people, not client feedback.5.0 / 53 reviews — a small sample, and we say so.
Client engagement feedback (internal)Post-engagement feedback collected by TCSA at the close of engagements. Collected by us, not independently audited — labeled accordingly wherever it appears.4.9 / 5150 responses.

Check them yourself: the Google Business Profile and AmbitionBox pages are public — search “Tranquility Cybersecurity” on either platform and read every review directly. The 4.9/5 figure used across this site is the third row: based on client engagement feedback collected by TCSA across 150 responses, and labeled as internal wherever it appears.

Section 4

The auditors behind the work

Numbers describe volume. These are the people accountable for it. Every TCSA engagement is led by one of the named auditors below — not routed to an anonymous pooled team — and each credential listed is one you can challenge us on.

Anonymized engagements

Audit work is performed under NDAs, so the engagement write-ups below are anonymized for client confidentiality. Each one gives the industry, the frameworks and what we did, but no client names. Named stories appear only with the client’s written permission. Everything else stays anonymized.

All published engagement examples live at tcsa.in/case-studies.

Section 6

Verify us

We tell prospective clients to verify every vendor they shortlist, including us. Three ways to do that, none of which require taking this page at its word:

  1. 1. Ask for references on a callDuring your scoping call, ask to speak with past clients — we arrange reference conversations, matched to your industry or framework where possible, subject to each client’s confidentiality consent.
  2. 2. Check the reviews yourselfOur Google Business Profile and AmbitionBox pages are public. Read every review, including any critical ones, without ever talking to us.
  3. 3. Meet the named auditor before signingAsk to meet the lead auditor who will actually run your engagement — not a salesperson — and check their credentials against the table on this page and their LinkedIn profiles.

Proof & Verification FAQs

Direct answers about how TCSA's numbers are produced — and how to check them yourself.

Why should I trust these numbers?
You should not have to trust them — that is the point of this page. Every figure is mapped to exactly what it counts and where it comes from: 1,000+ audits and clients in India, the US, the UK, Australia and the UAE trace to internal engagement records to date, the SOC 2 count to readiness and attestation programs supported, and zero first-time audit failures to certification and attestation outcomes across engagements to date. The ratings can be checked directly on Google and AmbitionBox without contacting us, and client references can be arranged on request. Anything we cannot source the same way, we do not publish.
Can I speak to past clients as references?
Yes. Ask during your scoping call and we will arrange reference conversations with past clients, matched to your industry or framework where possible. Each reference requires the client’s confidentiality consent, which is also why we arrange them on request rather than publishing a contact list.
Why are your clients anonymized?
Security and compliance work is performed under NDAs, and most clients do not want their audit history, control gaps, or compliance timelines made public. Named stories appear only with the client’s written permission. Everything else stays anonymized.
Who actually performs my audit?
A named lead auditor from the table on this page — Surendra Pal Singh (CISA and ISO 27001, 27701, and 42001 Lead Auditor), Parth Chauhan (ISO 27001/27701/42001 Lead Auditor, CEH), or Saundhi Chauhan (ISO 27001/27701/42001 Lead Auditor) — leads your engagement, not an anonymous pooled team. You can meet your lead auditor before signing anything, and verify their credentials on LinkedIn first. For SOC 2, the examination itself is performed and signed by an independent, US-licensed CPA firm, which we name before you sign with us, together with its licence number, the state board that issued it, and its current AICPA peer review enrolment. ISO certificates come from an accredited certification body. We deliver CERT-In audits, end to end, with our CERT-In empanelled partners.
