Client Overview

The client is one of India’s largest diversified enterprises, operating across several consumer-facing and industrial sectors. Their digital ecosystem included multiple customer applications, siloed digital teams, and independent platforms supporting millions of monthly interactions.

The company’s flagship Super App initiative required a unified, secure, and scalable foundation that could support cross-business integrations, high transaction throughput, and rapid product innovation across its digital portfolio.

Business & Technology Challenges

As the enterprise prepared to consolidate several standalone applications into a unified Super App, it faced a broad spectrum of architectural, operational, and security challenges.

Business Challenges

• Fragmented application ecosystem leading to inconsistent customer experiences
  
• Siloed engineering teams, duplicated development efforts, and slow release cycles
  
• Rising user demand for a single Super App experience
  
• Limited visibility into app performance and customer behavior across digital properties
  

Technology Challenges

• Weak CSPM posture with 30,000+ vulnerabilities across containers, images, misconfigurations, and policy gaps
  
• No governed Landing Zone or cloud security baseline
  
• High infrastructure costs due to premium components like commercial NGINX
  
• Firestore user-onboarding failures caused by misconfigurations during traffic spikes
  
• No centralized asset inventory or enterprise DLP controls
  
• Absence of Disaster Recovery and no validated failover strategy
  
• Limited API standardization and inconsistent integration patterns
  
• No hybrid cloud framework to integrate on-prem systems with Google Cloud
