Which IT Companies Help Insurance Firms Modernize Legacy Systems?

Many insurers still run their most critical operations on systems built 20 or 30 years ago. Policy administration, claims management, and billing often depend on COBOL code, mainframes, or monolithic systems that few people fully understand. These legacy systems still function, but they make every new product launch, integration, and regulatory update slower and more expensive.

Customers now expect instant quotes, digital self-service, and fast claims decisions. Insurtechs deliver all three. So the need for modernization has never been clearer. For most carriers, the question is no longer whether to modernize legacy systems, but who should help them do it without disrupting the business.

This guide compares three IT companies that help insurers tackle insurance legacy system modernization: Hicron Software, ScienceSoft, and Saigon Technology. You will learn:

• Why legacy system modernization in insurance has become a strategic priority
• Which criteria separate a strong modernization partner from a generic vendor
• What each company brings in competencies, experience, and delivery model
• How the three compare side by side, so you can match a partner to your situation

Key Takeaways:

• Hicron Software is the best choice for comprehensive, strategic modernization of complex enterprise environments, particularly for European insurers.
• ScienceSoft is a strong option when security and the North American market are top priorities.
• Saigon Technology makes sense for budget-focused team scaling with strong internal leadership.
• Legacy system modernization is a series of controlled moves and the right partner helps you choose the sequence.

Why Legacy System Modernization in Insurance Is a Priority

Legacy platforms rarely fail all at once. They weigh on the business gradually, through rising costs, slower releases, and growing risk. Here are the main pressures driving insurers toward modernization.

The Hidden Cost of Maintaining Legacy Systems

The direct costs are easy to see: licensing fees, maintenance contracts, and specialized support. The indirect costs are harder to spot and usually larger.

• Shrinking talent pools. Fewer engineers know older languages and platforms, so the people who do cost more and are harder to replace.
• Technical debt. Years of patches and workarounds make every change risky. A small product update can take months of testing.
• Blocked innovation. When IT capacity goes into maintaining legacy systems, little is left for new digital products, analytics, or AI.

Regulatory Pressure and Data Security

Insurance is one of the most regulated industries. Frameworks such as GDPR, DORA, Solvency II, and IFRS 17 demand accurate data, clear audit trails, and strong operational resilience. Outdated legacy systems often struggle to meet these requirements.

Unpatched or unsupported outdated software also creates security gaps. Insurers hold large amounts of sensitive personal and financial data, so any weakness is a serious exposure. Modern architectures make it easier to control access, track changes, and prove regulatory compliance.

Customer Expectations and Insurtech Competition

Policyholders compare their insurer with the best digital experiences they use every day. They expect to:

• Get a quote online in minutes
• Manage policies and documents through self-service portals
• File and track insurance claims from their phone
• Receive offers that reflect their actual needs and behavior

Insurtechs built on cloud-native platforms can launch products in weeks. Carriers running legacy insurance systems often need months. That gap in time-to-market is a real competitive risk and a key driver of insurance digital transformation.

The Biggest Myth: “Modernization Means Replacing Everything at Once”

Many insurers delay modernization because they picture a risky, multi-year “big bang” replacement. In practice, the most effective modernization approaches work step by step. Common strategies for effective legacy system modernization include:

Approach	What it means	When it fits
Rehost	Move the system to new infrastructure (often cloud) with minimal code changes	Quick cost and infrastructure wins
Replatform	Make targeted changes to run on a modern platform	Better performance without a full rewrite
Refactor	Restructure legacy code to improve maintainability and scalability	Core logic is valuable but hard to change
Rebuild	Rewrite the application with modern architecture	The existing system no longer fits business needs
Replace	Adopt a new commercial or custom platform	Off-the-shelf tools cover most requirements

A phased model such as the strangler fig pattern lets you replace parts of a legacy core gradually. For example, an insurer could move claims management into a separate microservice with its own API, while the core policy administration system keeps running unchanged. Each step delivers value and lowers risk.

In short: legacy system modernization is a series of controlled moves, not a single leap. The right partner helps you choose the sequence.

Why Enterprise Architecture Matters in Insurance Transformation

Insurance modernization programs that lack strong architectural leadership tend to produce the same problem in a new form: systems that are technically newer but just as hard to change. The Enterprise Architect is the role that prevents this.

In a typical insurance environment, policy administration systems, claims, billing, data platforms, and compliance reporting are tightly interdependent. A change in one area ripples through all the others. The Enterprise Architect maps these dependencies before any code changes begin. This role does three things that no other role does consistently:

• Defines the target architecture that guides every delivery decision throughout the program
• Sequences the modernization roadmap so that each step reduces complexity rather than adding to it
• Translates between IT and business by turning technical decisions into business terms and business priorities into architectural choices

Without that translation layer, insurers risk executing technically sound cloud migrations that miss business goals, or launching business-driven programs that underestimate integration complexity.

Strong architectural leadership produces a clear result: modernization becomes a governed transformation with measurable milestones and controlled risk at every stage, not a series of disconnected fixes that never quite add up.

How AI Can Accelerate Insurance Legacy Modernization

AI does not replace the experienced teams and architectural discipline that insurance legacy system modernization demands. But in the hands of skilled experts, it can meaningfully compress the timeline and reduce delivery risk.

The hardest part of any legacy transformation is understanding what the existing system actually does. Documentation is often incomplete. Business logic is buried in decades-old legacy code. Dependencies between modules stay invisible until something breaks.

AI-assisted analysis tools help here. They can scan large volumes of legacy applications, surface patterns, map component relationships, and produce first-draft documentation far faster than manual review. Architects and engineers get a clearer picture of what to refactor, replace, or preserve before a single line of new code is written. In practice, technologies like AI can cut discovery timelines significantly and help teams make better-informed architectural decisions earlier.

Further along in the program, AI can:

• Support refactoring and code transformation tasks
• Accelerate test generation and coverage
• Take on repetitive delivery work that would otherwise slow the team down
• Help document business logic and reduce reliance on tribal knowledge

All of this happens under continuous human review. None of this changes the fundamentals. In insurance, compliance, data security, and auditability are non-negotiable. Every AI-assisted output must be validated by engineers who understand the domain and by architects who hold the transformation accountable to a governed plan.

The right frame is simple: if enterprise architecture defines the path, AI helps skilled teams move along it faster. The human experts remain responsible for every decision that matters.
