Pre-Assurance Validator

Validate your ESG data against 200 automated rules across 5 frameworks before your assurer does. Catch completeness gaps, consistency errors, and calculation mistakes — get an assurance-readiness score in minutes.

Why Validate Before Assurance?

72% of BRSR Core assurance engagements encounter preventable data errors. Our validator catches them before your assurer raises them — saving weeks of rework and potential qualified opinions.

200 Automated Rules

Completeness checks, cross-reference validation, calculation verification, unit consistency, and boundary alignment across your entire ESG dataset.

5 Frameworks Covered

Validates against BRSR (SEBI), GRI Standards, AA1000 AccountAbility Principles, ISAE 3000 evidence requirements, and GHG Protocol calculation standards.

Assurance-Ready Score

Get a percentage readiness score with a prioritised fix list. Address critical issues before engaging your assurer to ensure a clean opinion.

Frequently Asked Questions

What frameworks does the Pre-Assurance Validator cover?

The validator checks your data against 5 frameworks: BRSR (SEBI format), GRI Standards, AA1000 AccountAbility Principles, ISAE 3000 evidence requirements, and GHG Protocol calculation methodology. All 200 rules are aligned with what assurance providers actually check during engagements.

Is the Pre-Assurance Validator a substitute for formal assurance?

No. The validator is a self-assessment tool that helps you prepare for formal assurance. It catches common errors before your assurer does, reducing the risk of qualified opinions and rework. You still need an independent assurance provider for BRSR Core assurance.

What data format does the validator accept?

Enter your ESG data directly into the validator interface. It covers all BRSR sections (A, B, C) with guided input fields. No file upload required — the tool walks you through each disclosure step by step.

How long does validation take?

A typical validation takes 30-60 minutes depending on data readiness. The validator provides real-time feedback as you enter data, so you can fix issues as you go.

Can I use this to prepare for BRSR Core assurance specifically?

Yes. The validator includes specific checks for all 9 BRSR Core KPIs that require assurance — GHG emissions intensity, water consumption, waste, energy, workforce diversity, LTIFR, human rights, pay equity, and board ESG training.

Ready for Formal Assurance?

Once your data passes validation, engage RSustain for BRSR Core assurance. Our 12-week Assurance Sprint takes you from validated data to assurance-ready.

What is BRSR?

The Business Responsibility and Sustainability Report (BRSR) is a mandatory ESG disclosure framework introduced by the Securities and Exchange Board of India (SEBI) in 2021. It replaced the older Business Responsibility Report (BRR) and became mandatory for the top 1,000 listed companies by market capitalisation from FY 2022–23.

BRSR is structured into three sections: Section A (company overview and general disclosures), Section B (management and process disclosures across the 9 NGRBC Principles), and Section C (principle-wise performance indicators split into Essential and Leadership indicators). From FY 2023–24, SEBI introduced BRSR Core — a subset of 9 key performance indicators that must undergo reasonable assurance by an independent assurance provider.

Key frameworks that complement BRSR include GRI Standards, TCFD, CDP, SASB, and the Indian Carbon Credit Trading Scheme (CCTS). Listed companies must file BRSR annually with BSE and NSE, and the report is publicly available on exchange websites.

For FY 2025–26, SEBI has expanded the BRSR Core assurance requirement to the top 500 companies, with the top 150 requiring reasonable assurance on all BRSR Core KPIs.

Frequently Asked Questions

What is pre-assurance validation? +
Pre-assurance validation is the process of checking your ESG data for errors, inconsistencies, and gaps before a formal assurance engagement. It reduces assurance costs by catching issues early.
What frameworks does the Pre-Assurance Validator cover? +
The tool validates data against five frameworks: BRSR (SEBI), GRI Standards, TCFD, CDP Climate Change, and SASB Standards.
Is the Pre-Assurance Validator a substitute for formal assurance? +
No. It is a preparation tool that helps you identify and fix data quality issues before the assurance provider begins their engagement. It reduces the number of queries and findings during formal assurance.
How many validation rules does the tool apply? +
The tool applies 200 automated validation rules covering data completeness, internal consistency, unit accuracy, trend anomalies, and framework-specific requirements.
What are the severity levels? +
Issues are classified as Critical (must fix before assurance), High (likely to be flagged by auditor), Medium (may be questioned), and Low (best practice improvement).
How does this reduce assurance costs? +
Companies that pre-validate typically see 30-50% fewer auditor queries, shorter assurance timelines, and lower total assurance fees because the data is cleaner on first submission.
Can I use this for BRSR Core assurance specifically? +
Yes. The tool specifically flags the 9 BRSR Core KPIs and applies BRSR Core-specific validation rules aligned with SEBI's reasonable assurance requirements.
What data format does the validator accept? +
The validator accepts structured data entry through its web interface. You can also upload Excel/CSV files for bulk data validation.
Who should use this tool? +
Sustainability teams preparing for assurance, internal auditors conducting pre-engagement reviews, and companies filing BRSR for the first time who want to ensure data quality.
Is there a free tier? +
The tool offers a free preview with limited validation rules. Full validation across all 200 rules and all five frameworks starts from Rs 4,999.
