National Stock Exchange (NSE)

National Stock Exchange (NSE)

The National Stock Exchange (NSE) faced a data security breach on its mutual fund platform, as flagged by the Federation of Independent Financial Advisors (FIFA). The breach exposed a critical flaw in client data segregation, where all clients under a main broker became visible to sub-broker partners, violating confidentiality protocols. Previously, client segregation was strictly maintained, but the new system failed to enforce this, leading to unauthorized access to investor data.Operational disruptions further compounded the issue, with transaction processing delays due to faulty integration of folio and investor identification numbers (IIN). Sub-brokers were denied login IDs, halting transactions entirely. Additional problems included restrictions on SIP/STP/redemption/switch transactions (now limited to one scheme per order), delayed SIP start dates (extended from 7 days to 1 month), and reduced validity of payment and ACH mandate links (from 48 to 24 hours).Crucially, transaction alerts and intimations such as SIP bounces, IIN changes, approvals/rejections, and mandate updates stopped being sent to registered distributor IDs, leaving investors and advisors uninformed about critical actions. The breach and operational failures collectively risked financial fraud, reputational damage, and loss of investor trust, though no direct evidence of data theft was reported.
