CDSL Share Price Falls on July 21, 2026, After SEBI Imposes a ₹1 Crore Penalty for Cybersecurity Lapses

CDSL share price traded lower on Tuesday, July 21, 2026, after the Securities and Exchange Board of India (SEBI) imposed a ₹1 crore penalty on the depository for failing to comply with cybersecurity and cyber resilience requirements. The penalty relates to a malware attack that disrupted the company's systems in November 2022. 

The stock touched an intraday low of ₹1,367.20 on the NSE, compared with the previous close of ₹1,385.20, marking a decline of ₹18 or nearly 1.30% during the session.  

Why Did SEBI Penalise CDSL? 

SEBI imposed a total penalty of ₹1 crore, comprising ₹90 lakh under the SEBI Act and ₹10 lakh under the Depositories Act. The regulator has directed CDSL to pay the amount within 45 days. 

According to SEBI's order, CDSL failed to classify its internet-facing Active Directory Federation Services (ADFS) server as a critical asset and excluded it from vulnerability assessment and penetration testing (VAPT). The regulator also noted that basic cybersecurity controls required under its framework were not implemented despite deficiencies being highlighted during an inspection in August 2022. 

SEBI further observed that unauthorised access to CDSL's systems had begun as early as November 2021, nearly a year before the malware attack was detected. 

CDSL clarified that the order would have no material impact on its financials, operations or other business activities, apart from the payment of the penalty.

The malware attack, detected on November 18, 2022, affected 135 of 547 servers and 177 of 506 desktops and laptops, according to SEBI's order. 

The incident disrupted several critical depository functions, including settlement, pay-in/pay-out, and pledge-related operations. 

CDSL Share Price Performance 

As of July 21, 2026, at 11:29 AM, CDSL share price was trading at ₹1,369.40 per share on the NSE, down 1.14% from the previous close of ₹1,385.20. 

During the session, the stock hit an intraday low of ₹1,367.20, reflecting a decline of ₹18 or nearly 1.30% from the previous closing price. 

Conclusion 

CDSL share price remained under pressure after SEBI imposed a ₹1 crore penalty over cybersecurity compliance failures linked to the 2022 malware attack. While the regulator highlighted deficiencies in the company's cybersecurity framework, CDSL stated that the order is not expected to have any material impact on its business operations beyond the payment of the penalty.
