India’s top stock exchanges—the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE)—have temporarily restricted website access from overseas IP addresses following a surge in cyberattacks targeting critical financial infrastructure in recent days. This precautionary move comes after attempted intrusions into the exchange’s web systems, highlighting broader concerns regarding escalating cyber threats against Indian institutions.

The decision was made following an emergency meeting of top officials from NSE and BSE after sophisticated monitoring tools detected an attempt to breach one of the exchange websites. As a result, certain overseas IPs have been blocked, while select foreign clients are still able to access via whitelisted IP addresses. This action does not affect foreign institutional investment (FII) operations, which continue securely through unaffected trading terminals.

A BSE spokesperson said, "As a critical Market Infrastructure Institution (MII), BSE proactively and continuously monitors cyber risks both domestically and internationally. As a precautionary and protective measure, specific websites and locations have been blocked to safeguard users and systems."

BSE further clarified that the monitoring and restrictions are dynamic, evaluated on a case-by-case basis, and access may be restored once a thorough threat assessment confirms safety. Similar measures have been implemented by NSE, though they have not issued an official statement at the time of reporting.
