Strengthening E-Commerce security for a global retail leader

With multiple brands under its umbrella, the client manages several independent web and mobile applications. This landscape requires collaboration across diverse design, development, and maintenance teams, as well as coordination with various stakeholders.
Frequent release cycles, ongoing enhancements, and numerous third-party integrations add layers of complexity, demanding consistent adherence to rigorous security standards throughout the SDLC.
Security vulnerabilities are reported through various channels, making the tasks of tracking, monitoring, and remediation both continuous and resource-intensive. A single lapse can lead to exposure of personal data or substantial financial losses for both the client and their customers.

Nagarro partnered closely with the client to embed security best practices throughout the development lifecycle, including requirements gathering, design, and code reviews. Our security experts conduct comprehensive vulnerability assessments and penetration tests to identify and evaluate risks early in the process. 
We handled over 20 applications from 10+ brands/business units, reviewing designs & monitoring more than 500 changes in applications every year. And oversaw vulnerability management and remediation of over 100+ vulnerabilities every year. 
By employing a hybrid approach—combining automated tools and manual testing—we ensure all applications and third-party integrations are thoroughly reviewed, aligning with OWASP (Open Web Application Security Project) guidelines.
Nagarro also supports the client’s vulnerability management process through root-cause analysis, fix verification, and strategic recommendations, strengthening their overall security posture.

The implementation of a proactive, secure-by-design development approach has significantly improved the client’s security resilience.
Cost savings were realized by identifying and mitigating vulnerabilities early, reducing the risk of downstream issues and breaches. A standardized security framework now guides development efforts across brands and applications, simplifying updates, scaling, and integration with new technologies or compliance mandates.
Ongoing collaboration between Nagarro, development teams, and key stakeholders allows for continuous risk assessment, timely remediation planning, and long-term process improvements to prevent recurring vulnerabilities.
This strategic engagement represents a long-term partnership with the client, supporting their mission to build and maintain secure digital applications.
