Global document storage solution

Description

A re-insurance company needed a secure, global solution for storing confidential documents across multiple countries, each with unique security policies. Despite over a year of planning, the project had not yet begun.

Challenges

The company adheres to strict security standards for personal information storage and access rights management, with external audits conducted every six months to ensure compliance. The primary challenge was to develop a system that met these security standards while facilitating efficient document management.

Project Constraints

1. Avoid High Auditing Costs:
   The company operates under strict security standards, requiring certifications for all operational software. Introducing a new system risked significantly increasing audit expenses.

2. Ensure Document Security:
   With sensitive client data involved, maintaining robust security measures was paramount to comply with privacy and data protection regulations.

3. Integrate with Existing Systems:
   To minimize technical debt and adhere to certification requirements, seamless integration with existing authentication and authorization systems was prioritized.

Solution

Through a collaborative effort between client representatives and the development team, the project was successfully delivered by leveraging existing external audit processes. This approach enabled the creation of a scalable, low-maintenance solution that minimized both development and auditing costs while meeting stringent compliance requirements.

Key Architectural Features

• Eliminated Auditing Costs:
  By integrating Microsoft Azure SSO and utilizing data from pre-certified systems, the solution completely removed the need for additional security system audits.

• Enhanced Document Security:
  Robust document protection was achieved through Governance-led integrations with Salesforce, ensuring compliance with international security standards.

• Scalable and Secure Deployment:
  The system was deployed on Kubernetes, utilizing Azure Cloud for its ability to deliver both scalability and enhanced security.

Technology Stack

The solution incorporated a comprehensive and modern technology stack, including:

• .NET: Core development framework for building the application.
• Domain-Driven Design (DDD) and Event Sourcing: For robust architectural patterns and precise data handling.
• Alfresco DMS: Ensured efficient and secure document management.
• Azure Cloud: Combined with Docker, Redis, and Azure Service Bus, to provide scalable cloud services and streamlined infrastructure.
• Kubernetes: Used for container orchestration, ensuring reliability and fault tolerance.

Achieved Metrics

• Cost Optimization:
  Significantly reduced both development and auditing expenses through strategic use of existing certifications and infrastructure.

• Compliance and Security:
  Successfully adhered to international security standards for document storage and management.

• Scalability and Maintenance:
  Delivered a highly robust system with low operational overhead and efficient maintenance processes.
