Modern Engineering for Regulatory Compliance: How Financial Institutions Can Innovate Securely

In the fast-evolving world of financial services, the pressure to innovate is matched only by the imperative to comply with stringent regulatory and security requirements. As banks, insurers, and wealth managers modernize their technology foundations, they must do so with a laser focus on compliance, risk management, and data protection. Modern engineering practices—such as agile development, cloud migration, and microservices—are not just enablers of speed and innovation; they are essential tools for embedding compliance and security by design. At Publicis Sapient, we help financial institutions harness these practices to create resilient, future-ready organizations that can thrive in a complex regulatory landscape.

The Compliance Challenge in Financial Services

Financial institutions operate in one of the most regulated industries in the world. Decades-old legacy systems, fragmented data, and siloed operations make it difficult to respond quickly to regulatory changes, integrate new technologies, or deliver seamless, secure digital experiences. The cost of inaction is high: slow time-to-market, increased operational risk, and missed opportunities for growth. Outdated technology alone cost financial institutions $36 billion in 2022, a figure expected to rise sharply as digital-native competitors accelerate their disruption.

Modern Engineering: Embedding Compliance and Security by Design

True digital transformation in financial services requires more than technology upgrades—it demands a holistic engineering mindset. Publicis Sapient’s approach is built on five key pillars that directly address compliance and security:

• 1. Agile Engineering

  We embed agile principles across teams, shifting from project-based to product-based thinking. This enables rapid iteration, continuous learning, and faster delivery of new features and regulatory changes. Agile engineering ensures that compliance requirements are addressed early and often, with regular feedback loops and transparent progress tracking.

• 2. Cloud Migration

  Migrating critical workloads to secure, scalable cloud environments is foundational to modern compliance. Cloud adoption not only reduces costs and increases agility, but also enhances disaster recovery, data residency, and the ability to implement automated controls. Our partnerships with leading cloud providers ensure that every migration is secure, compliant, and future-proof.

• 3. Microservices and APIs

  Modernizing monolithic legacy systems by engineering microservices and API platforms allows for modular, auditable, and secure architectures. This approach accelerates digital innovation, enables seamless integration of new technologies (including AI and advanced analytics), and allows for granular control over data access and processing—key for regulatory compliance.

• 4. Security and Compliance by Design

  Security and regulatory compliance are embedded from the outset. Our solutions ingrain robust controls, automated testing, and continuous monitoring to ensure every digital product meets the highest standards for data protection and regulatory adherence. Automated controls and real-time monitoring enable proactive risk management and rapid response to emerging threats or regulatory changes.

• 5. Data-Driven Value Creation

  We unlock the power of data by connecting and refining it across the enterprise, making it actionable for both compliance and customer experience initiatives. Our data modernization strategies enable real-time insights, predictive analytics, and personalized services, all while ensuring data lineage, quality, and governance are maintained for regulatory reporting.

Automating Controls and Continuous Monitoring

Automation is a cornerstone of modern compliance. By integrating automated controls into the software development lifecycle, financial institutions can ensure that compliance checks are performed consistently and at scale. Continuous integration and continuous deployment (CI/CD) pipelines, coupled with automated testing, enable rapid, secure releases while maintaining regulatory standards. Continuous monitoring tools provide real-time visibility into system health, security posture, and compliance status, allowing for immediate remediation of issues and transparent audit trails.

Real-World Impact: Publicis Sapient in Action

Our work with leading financial institutions demonstrates the power of modern engineering for secure, compliant innovation:

• Lloyds Banking Group partnered with Publicis Sapient to revolutionize its engineering organization. By adopting lean methods, agile principles, and value stream analysis, Lloyds achieved a 20–30% reduction in time from backlog to production, a 10–20% reduction in effort for architectural and operational changes, and a 30% improvement in quality. Automated controls and continuous monitoring were integral to meeting regulatory requirements while accelerating digital product launches.
• Nationwide Building Society leveraged our Speed Layer platform to ensure 24/7 data availability and resilience for digital services. With over 95% automated test coverage and robust disaster recovery, Nationwide achieved millisecond-level performance and significant cost savings, all while maintaining strict compliance with data protection regulations.
• API Management and Fraud Prevention: For Lloyds, we implemented an API management platform aligned to their API strategy, using the latest features of Google’s Apigee X platform. In another initiative, we helped reduce payment fraud by 95% through the implementation of "Safelists"—a list of pre-validated account numbers—demonstrating how digital journeys and targeted friction can enhance both security and compliance.

Best Practices for Secure, Compliant Innovation

• Incremental Modernization: Use proven strategies like the ‘strangler’ approach to incrementally replace legacy components, minimizing risk and disruption while maintaining business continuity.
• Seamless Integration: API-driven architectures enable easy integration with existing systems, supporting both greenfield and brownfield environments.
• Automated Testing and CI/CD: Achieve high levels of automated test coverage, with CI/CD pipelines enabling rapid, secure deployments.
• Data Governance: Implement centralized data platforms, shared data domains, and automated data quality management to ensure compliance and trust.
• Cloud-Native Design: Leverage containerization, infrastructure as code, and automation to build resilient, scalable platforms that can adapt to changing business needs and regulatory requirements.

The Path Forward: Continuous Compliance and Innovation

Modernization is not a one-time event—it’s a journey of perpetual evolution. By embedding engineering excellence, cloud-native platforms, and data-driven strategies at the core, financial institutions can adapt, innovate, and create value continuously. With Publicis Sapient as your partner, you can confidently navigate the complexities of regulatory compliance while accelerating your digital transformation.
