InnaIT strengthens identity security and authentication for a large Indian private sector bank

Executive Summary:

One of India’s largest private sector banks strengthened authentication across its Core Banking System (CBS) by enhancing password-based access with Precision Biometric’s InnaIT Biometric 2FA platform, combining biometric and PKI-based identity verification. Achieved full production in three months post proof of concept securing over 120,000 users through an automated, highly available identity platform, including 60,000 users onboarded in just 45 days.

The solution delivered 3,000 transactions per second, 16 times the bank’s required benchmark, while resolving RBI’s CSITE observations on identity and authentication and sustaining zero audit findings across the next three consecutive annual audits. The result: stronger identity assurance, reduced regulatory risk, and a scalable foundation for the bank’s continued digital transformation.

About the Client:

One of India’s largest private sector banks operates one of the country’s most extensive digital banking ecosystems, supporting thousands of employees and processing millions of high-value financial transactions every day. As digital adoption accelerated and identity-centric cyber threats became more sophisticated, the bank recognised the need to strengthen authentication across its mission-critical Core Banking System (CBS) and other critical applications. The objective was to enhance cyber resilience, improve identity assurance, and create a secure foundation for future digital transformation.

To achieve this, the bank embarked on a strategic identity modernisation initiative focused on replacing traditional password-based authentication with a scalable, enterprise-grade biometric authentication framework. Beyond addressing immediate security and regulatory requirements, the initiative was designed to improve operational efficiency, simplify compliance, and establish a future-ready identity platform capable of securely supporting the bank’s continued business growth and digital innovation.

Client Challenges:

The banking industry has become a prime target for identity-based cyberattacks, where compromised credentials, phishing, password sharing, and identity impersonation pose greater risks than traditional infrastructure attacks. As financial institutions accelerate their digital transformation journeys, identity has emerged as the new security perimeter. Coupled with evolving regulatory expectations, banks are under increasing pressure to strengthen identity assurance, protect access to mission-critical systems, and deliver robust security without compromising operational efficiency or user experience.

Against this backdrop, one of India’s largest private sector banks recognised that its password-based authentication framework for the Core Banking System (CBS) no longer met its evolving security and compliance objectives. Traditional credentials exposed the organisation to password sharing, insider risks, and identity impersonation, while regulatory observations underscored the need for stronger authentication controls. The bank sought a future-ready authentication platform that could eliminate identity-related risks, simplify secure access for thousands of employees, scale seamlessly across the enterprise, strengthen regulatory compliance, ensure uninterrupted banking operations, and enable continued digital transformation.

The Solution:

To address these challenges, Precision Biometric deployed the InnaIT Biometric Multi-Factor Authentication (MFA) platform, replacing traditional password-dependent authentication with biometric identity verification.

The implementation extended beyond authentication by modernising the bank’s enterprise identity framework through automated identity lifecycle management, seamless integration with its identity governance ecosystem, self-service onboarding capabilities, and a resilient high-availability architecture.

The program progressed from proof of concept to full production in just three months, enabling rapid enterprise-wide adoption while maintaining uninterrupted business operations. More than 120,000 users were successfully secured through a fully automated identity platform designed for scalability, operational resilience, and long-term business growth.

Benefits:

The initiative delivered measurable business value across security, compliance, operational efficiency, and enterprise scalability.

Strengthened Identity Assurance

Biometric authentication eliminated password sharing and significantly reduced the risk of identity impersonation, creating a stronger trust framework for accessing critical banking applications.

Improved Operational Efficiency

Automation streamlined the complete identity lifecycle, reducing administrative effort while enabling the secure onboarding of over 120,000 users with zero unplanned downtime.

Enhanced Regulatory Compliance

The bank successfully addressed RBI CSITE authentication observations and maintained zero related audit findings across three consecutive years, reinforcing governance and reducing regulatory risk.

Enterprise-Scale Performance

The solution delivered authentication throughput of 3,000 transactions per second, exceeding the bank’s required benchmark by 16×, providing ample capacity to support future growth and application expansion without performance constraints.

Closing Thoughts

Modern identity security is no longer viewed as only a cybersecurity initiative. It has become a strategic business capability that enables organisations to operate with greater confidence, resilience, and agility. By replacing traditional password-based authentication with biometric identity assurance, the bank strengthened its cyber resilience, enhanced regulatory compliance, simplified identity operations, and established a scalable foundation for future digital banking initiatives. This transformation demonstrates that modern identity assurance delivers far more than stronger security. It enables financial institutions to reduce business risk, improve operational efficiency, strengthen customer and regulatory trust, and accelerate digital innovation while creating measurable long-term enterprise value.
