AI Modernization for Regulated Industries: Engineering for Governance, Traceability and Scale

In regulated industries, modernization is never just a speed play. It is a control challenge. Healthcare organizations, financial institutions and life sciences companies cannot afford transformation that breaks continuity, obscures decision logic or creates new compliance risk. The systems at the center of the business often process claims, support payments, manage critical data flows or govern regulated content. They are essential, deeply interconnected and often poorly documented.

That changes how engineering must work.

At Publicis Sapient, we help regulated enterprises modernize and embed AI in ways that are faster, but also more governable, more traceable and more resilient in production. Our approach combines Sapient Slingshot, Sapient Bodhi and human-in-the-loop delivery to uncover buried business logic, generate verified specifications, automate testing and orchestrate AI inside governed workflows. The result is modernization and AI activation that move with confidence, not compromise.

When compliance is non-negotiable, engineering starts with visibility

Many regulated transformation programs stall for the same reason: the business logic that matters most is hidden below the surface. Rules live in legacy COBOL, batch jobs, copybooks, undocumented integrations and institutional memory. Teams know change is needed, but every release introduces uncertainty because dependencies are unclear, requirements are incomplete and testing remains too manual.

In that environment, generic AI tools are not enough. Regulated organizations need engineering that makes systems visible before it tries to make them faster. They need to know what the legacy estate actually does, how decisions are made, what dependencies exist and where human validation must stay in the loop.

That is why Publicis Sapient focuses on foundations first. We surface buried logic, document dependencies, generate verified artifacts and embed governance before scale begins. Instead of bolting on controls after deployment, we engineer for auditability, resilience and accountability from the start.

Sapient Slingshot: from hidden legacy logic to verified modernization

Sapient Slingshot modernizes legacy systems by turning existing code into verified specifications and generating modern software with full traceability. It extracts business rules from undocumented code, maps dependencies across systems and automates testing across the software development lifecycle.

For regulated industries, that matters because legacy modernization is rarely just a code conversion exercise. It is a documentation and risk-reduction exercise. Slingshot helps engineering teams preserve the rules the business depends on while making them visible, testable and governable. Functional specifications can be generated directly from legacy applications. Flowcharts, field mappings and dependency views help teams validate what matters. Test creation becomes more automated and modernization can proceed without losing critical business logic.

This is how organizations avoid the false tradeoff between speed and control. They do not have to modernize blindly, and they do not have to rely on slow manual analysis alone. They can move faster because the system has become more understandable.

Sapient Bodhi: governed AI inside real business workflows

Modernization alone does not create enterprise AI value. Once systems are more visible and structured, AI still has to operate safely inside workflows that involve sensitive data, regulated decisions and multiple approval layers.

Sapient Bodhi is Publicis Sapient’s enterprise AI platform for building, deploying and orchestrating agentic workflows with governance built in. It connects AI to governed data, role-based access, enterprise context and auditability from day one. Rather than leaving AI isolated as a pilot or assistant, Bodhi embeds it where work actually happens.

That is especially important in regulated environments. AI must do more than generate output. It must operate within defined controls, support clear accountability and fit into workflows that can be reviewed, monitored and improved over time. Bodhi helps make that possible by bringing orchestration, observability and workflow control into the production environment.

Human-in-the-loop delivery: speed with expert oversight

In regulated transformation, trust is built through validation. Publicis Sapient uses a human-in-the-loop delivery model so that AI acceleration is paired with expert review at the moments that matter most.

Product owners can validate generated specifications. Engineers can review target-state designs and implementation outputs. Business stakeholders can confirm that critical logic has been preserved. Compliance and governance teams can maintain oversight without slowing every step to a crawl.

This model is not about keeping work manual. It is about applying human judgment where it reduces risk and improves confidence. AI handles heavy lifting across discovery, specification, testing and workflow execution. People remain responsible for validating high-impact decisions, governing exceptions and ensuring that change is production-ready.

Built for traceability, testing and continuity at scale

The difference between a promising pilot and production-ready transformation often comes down to operational discipline. In regulated industries, that means lineage, monitoring, access control, audit logs and automated testing cannot be afterthoughts.

Publicis Sapient helps organizations design governed delivery around those realities. We create workflows where dependencies are documented, specifications are verified, tests are automated and AI outputs can be reviewed in context. We build data and AI foundations with ownership, controls and observability embedded before deployment. And we help clients modernize in ways that protect continuity, so critical services remain stable while change accelerates.

This is engineering for regulated scale: not just faster builds, but systems that hold up under audit, support safe releases and continue improving over time.

Proven in healthcare, banking and pharma

This approach is already delivering outcomes in high-stakes environments.

In healthcare claims modernization, Publicis Sapient used Sapient Slingshot to help a leading U.S. healthcare company accelerate migration of decades-old mainframe systems by 3x, modernize 10,000 screens and reduce modernization costs by 30%. Legacy COBOL was transformed into maintainable Java and React, with functional specifications and test cases generated automatically and human-in-the-loop validation supporting quality and compliance throughout the effort.

In banking, Publicis Sapient applied its modernization approach to a major British retail and commercial bank with highly complex Unisys COBOL systems. More than 350 files and nearly half a million lines of code were analyzed in eight weeks to produce program overviews, flowcharts, field mappings and fan-out diagrams. The result was a 70% reduction in manual code-to-spec effort, 95% accuracy in generated specifications and a 40 to 50% increase in migration speed.

In pharma, a global pharmaceutical company used Bodhi to transform compliant content creation at scale. Hosted in the client’s environment, the solution streamlined ingestion, MLOps and creative workflows so teams could produce compliant-ready copy and imagery far faster. The program delivered 75% faster content production, up to 45% cost reduction and faster time-to-market, while supporting localization, reuse and secure integration with the client’s existing architecture. In broader healthcare marketing contexts, AI agents trained on brand, regulatory and medical context helped scale content across more than 30 markets while maintaining governance controls.

Move faster without sacrificing control

For regulated industries, the goal is not unchecked acceleration. It is controlled acceleration.

With Sapient Slingshot, buried business logic becomes visible, verified and ready for modernization. With Sapient Bodhi, AI is embedded into governed workflows with the context, controls and auditability required for production. With human-in-the-loop delivery, organizations gain the speed of AI with the assurance of expert oversight.

That is how Publicis Sapient helps regulated enterprises modernize and scale AI without sacrificing governance, traceability or business continuity. We engineer transformation for the environments where control matters most.
