GitLab-Based DevSecOps Transformation for a Leading Indian Bank
Client: Leading Indian Bank Industry: Banking / Financial Services
Challenge
The bank was undergoing rapid digital transformation, with multiple application teams working across channels such as mobile banking, internet banking, and internal platforms. However, the software development lifecycle was fragmented, with separate tools for code management, CI/CD, security testing, and release management.
This resulted in inconsistent deployment processes, delayed releases, limited traceability, and reactive security practices. Given the regulatory environment, the bank needed a unified, secure, and auditable DevSecOps platform that could scale across teams while ensuring compliance and governance.
Approach
ACG initiated the engagement by assessing the existing development ecosystem, identifying inefficiencies across code management, pipeline orchestration, and security integration.
We designed a unified DevSecOps architecture centered around GitLab, consolidating source code management, CI/CD pipelines, and security testing into a single platform. Secure coding practices and automated security scans (SAST, DAST, dependency scanning) were embedded into the pipelines to enable a Shift-Left approach.
Role-based access controls, audit logging, and compliance workflows were configured to align with banking regulations. Automation was introduced across build, test, approval, and deployment stages, ensuring consistency and traceability.
Solution
A fully integrated GitLab-driven DevSecOps platform was implemented, enabling end-to-end visibility and control over the software development lifecycle. The solution provided a standardized, secure, and scalable framework for application delivery across the bank.
Results
⚙️ 70% automation across build and deployment pipelines 🚀 3x faster release cycles across application teams 🔐 60% reduction in security vulnerabilities through early detection 📊 End-to-end traceability for audits and regulatory compliance
