One platform, from raw document to filed disclosure.
Atteston covers the full reporting lifecycle — capture, compute, report and attest — without ever losing the thread between a filed number and its source.
Metric Ledger
Every quantitative value lives as a row that moves draft → confirmed → locked. State is the source of truth — only locked numbers enter the report.
State machineAI Evidence Extraction
Upload a DISCOM bill, invoice or payroll file. AI proposes value + unit + the exact source snippet and bounding box — async and fail-soft, never blocking.
Human-confirmedKPI Computation Engine
Scope 1/2, intensity and the full Section C KPI set, computed from locked inputs against a versioned, citation-backed factor library — every figure shows its trace.
Versioned factorsMulti-plant Roll-up
Consolidate plants and business units along a defined boundary. Aggregate without losing the plant-level lineage an assurer will ask to inspect.
Consolidation boundaryMaker–Checker Controls
Segregation of duties enforced in software: preparer, reviewer, approver. No single person can both enter and lock a value.
SoD enforcedAssurance Evidence Pack
One click produces a PDF + structured index + anchored checkpoint for the Core subset — built for the registered assurer to re-perform and annotate.
Assurer-readyHash-chained Audit Store
Append-only event log of every state change, externally anchored. Tampering is detectable; history is reconstructable; the chain is independently verifiable.
Externally anchoredAssurance Pre-check
Before export, Atteston flags every gap — blocker, warning, info — so missing evidence and unconfirmed values surface before the assurer ever sees them.
Export gatingBRSR / ESG Report & XBRL
Assemble Sections A, B and C into the SEBI BRSR layout — board-signable PDF plus an XBRL-mappable structured export with a field-to-taxonomy map.
SEBI formatExtraction you can point a finger at.
Atteston's AI reads the document and proposes a value, a unit, and the precise span of text it came from — with a bounding box on the page. It is a proposal, never a decision.
- Value + unit + source snippet + bounding box on every extraction
- Runs async and fail-soft — a slow model never blocks data entry
- Lands in draft only — a human must confirm against the snippet
Every KPI shows its working.
Scope 1 & 2, intensity ratios and the wider Section C set are computed from locked inputs against a factor library that is versioned and citation-backed. Click any figure and trace it back to the inputs and the exact emission factor used.
- Calculation trace from result → inputs → factor → citation
- Factors are versioned — re-running a prior period uses that period's factor
- Roll-up respects the consolidation boundary you defined
Engineered for regulators, not just users.
Atteston is built India-first: data resident in-region, privacy aligned to DPDP, and an audit chain designed to satisfy an external assurer's scrutiny.
India-resident
Primary region ap-south-1, with a separate WORM account for immutable records. Your data does not leave the jurisdiction.
DPDP-aligned
Personal data handling designed around India's Digital Personal Data Protection Act, with row-level security isolating every tenant.
Append-only audit
Hash-chained, externally anchored event log. Every state change is recorded and the chain is independently verifiable.
Immutable evidence
Content-addressed, write-once-read-many evidence store. The document behind a number can never silently change.
One ledger, three jobs to be done.
Prepare with confidence
Capture data across plants, let AI accelerate the grind, and watch the pre-check tell you exactly what is missing before anyone signs.
Govern the numbers
Maker-checker, segregation of duties and a tamper-evident audit chain give controllers the same rigour they expect from financial reporting.
Re-perform, don’t reconstruct
A structured evidence pack with anchored checkpoints means the assurer inspects and re-performs the Core subset instead of chasing spreadsheets.
Make the next reporting cycle defensible by design.
