- Vigil - India Corporate Red-Flag ScannerScans NSE-listed companies for corporate red flags across seven signal tables: credit ratings, insider trading, promoter pledges, takeover (SAST) disclosures, encumbrance events, exchange surveillance (GSM/ASM/ESM) and related-party transactions. Pull a stock’s consolidated report, or browse and filter each dataset.
Ownership, pledge & takeover
Signals about who owns the company, how much of it is pledged, and any change-of-control activity.
- PledgeWhat promoter share pledging means, how pledge differs from the broader encumbrance category (lien, NDU, negative lien), why the quarterly snapshot and the event feed complement each other, and why heavy pledging is a governance red flag.
- EncumbranceThe real-time promoter pledge / unpledge / invocation event feed: what creation, release and invocation mean, the encumbrance types, how to read the percentages, and how it complements the quarterly pledge snapshot.
- Takeover (SAST)The SEBI Takeover Code in plain language: ownership thresholds, Reg 29(1)/29(2) disclosures, when a 25% crossing forces an open offer, acquisition modes, and the famous takeover battles that show it in action.
Trading & surveillance
What insiders are disclosing, and when the exchange places a stock under a surveillance framework.
- Insider TradingWho counts as an insider, what they must disclose, and how to read promoter / director / KMP buy, sell and pledge transactions filed under SEBI PIT Regulation 7 on NSE.
- SurveillanceWhat it means when NSE / SEBI place a stock under surveillance: the GSM, ASM and ESM frameworks with their stages, price bands and settlement rules, the other risk flags (IRP, ICA, encumbrance), and the NSE series codes.
Governance & related-party
Related-party dealings and the quarterly financial-results disclosures that sit behind them.
- Related Party TransactionsWhat Related Party Transactions are, why most are routine, how they are disclosed under SEBI LODR Regulation 23, the transaction types and relationship groups, and what actually warrants a second look.
- Quarterly ResultsHow quarterly financial results are sourced from NSE XBRL filings and made comparable across ~750 companies: line items extracted (incl. banking NPA), matched company sets, limitations, and an independent 4-phase validation with documented data-quality exclusions.
ESG (BRSR)
India’s Business Responsibility and Sustainability Report: the ESG methodology and its data-quality caveats.
- BRSR MethodologyHow India BRSR (Business Responsibility and Sustainability Report) ESG disclosures are sourced from SEBI XBRL, mapped to the 9 Principles via the SEBI taxonomy, and normalized so companies of very different sizes can be compared.
- BRSR Data QualityWhy BRSR ESG filings carry data-quality noise, the classes of issue found across the Nifty Total Market universe, the two-layer (algorithmic + printed-PDF) validation, and the honest bottom line: reliable for aggregates, verify specific company cells against the PDF.
Filings, data & validation
Where the data comes from, how XBRL enables cross-company analysis, how it is validated, and the known data quirks.
- Data SourcesEvery VIGIL dataset and where it comes from: the official NSE / SEBI source, coverage window, refresh cadence, key fields and known quirks - all built from publicly available India corporate filings.
- India XBRL FilingsWhat XBRL is and why it enables cross-company analysis, the major India corporate XBRL filing types under SEBI LODR, the old vs new NSE Integrated Filing systems, and the official pages to download each.

- Known IssuesCompany name variations across NSE datasets, the Tata Motors demerger, and the ISIN-based master table being built to unify name variants and eliminate duplicate search results.
