New Delhi | State-owned Punjab National Bank (PNB) has approved a large-scale ₹3,400 crore IT and AI upgrade plan to strengthen its digital security infrastructure, combat rising cyber frauds, and enhance customer safety across banking channels.
The decision comes at a time when India’s banking sector is witnessing a sharp rise in digital frauds, phishing attacks, account takeovers, and AI-driven cyber threats. Financial institutions are increasingly exposed to sophisticated attack methods that are evolving faster than traditional security systems.

PNB Managing Director and CEO Ashok Chandra said the bank is accelerating its digital transformation strategy by integrating AI-based analytics, predictive fraud detection systems, and automated customer service tools to improve both operational efficiency and cybersecurity resilience.
He further stated that the bank will soon issue a Request for Proposal (RFP) to appoint a specialized consultant for generative AI and advanced data analytics projects. The focus will include cyber risk management, real-time fraud monitoring, and intelligent threat detection systems designed to identify suspicious transactions before they are executed.
As part of this transformation, PNB has set up a dedicated “Strategic Innovation Lab”, which will serve as a central hub for technological experimentation and AI-led development. Around 200 engineers, including professionals from leading institutions such as IITs and NITs, have been onboarded to work on cybersecurity and AI-driven banking solutions.
This team will focus on strengthening digital banking platforms including mobile banking, internet banking, and ATM networks, with the goal of creating systems capable of detecting abnormal transaction patterns in real time and preventing potential fraud attempts instantly.
Cybersecurity experts note that India’s rapid digital banking expansion has also created new opportunities for cybercriminals. Methods such as social engineering, malware attacks, fake customer support scams, and unauthorized account access are becoming increasingly common, making traditional security frameworks less effective.
Renowned cybercrime expert and former IPS officer Prof. Triveni Singh said that banking fraud is now entering a more advanced phase where criminals are leveraging modern technologies. He observed, “Cybercriminals today are using social engineering, malware, and AI-based tools to bypass traditional security layers. Banks must shift towards real-time monitoring and behavior-based analytics to detect fraud before damage occurs.”
On the financial front, PNB reported a net profit of ₹5,225 crore in Q4 FY26, marking a 14% year-on-year increase. However, the bank’s net interest income declined by 3.5%, reflecting pressure on margins due to faster transmission of lending rate cuts compared to deposit rate adjustments.
Despite margin challenges, the bank continued to show stable growth in deposits and credit expansion. Domestic deposits rose by 9.1%, while savings account deposits increased by 6.2%. The bank also added nearly 47 lakh new accounts, mobilizing around ₹22,000 crore in deposits, indicating strong retail participation.
In the MSME segment, PNB recorded a significant expansion, with its loan portfolio rising by nearly 20% to ₹1.95 lakh crore, reflecting steady demand from small and medium enterprises despite global economic uncertainties.
Industry experts believe that PNB’s ₹3,400 crore investment marks a major step toward digital modernization in India’s public banking sector. However, they also emphasize that successful implementation and continuous system upgrades will be crucial in keeping pace with rapidly evolving cyber threats.
With digital transactions becoming the backbone of modern banking, AI-powered security systems are expected to play a critical role in the future. PNB’s initiative is being seen as a strategic move to not only strengthen cybersecurity defenses but also enhance customer experience through automation and faster service delivery.
As digital banking continues to expand, the focus is clearly shifting toward building intelligent, resilient, and proactive security systems capable of safeguarding financial ecosystems against the next generation of cyber threats.
