Legacy insurance systems are expensive to maintain, notoriously complex, and not equipped to meet modern demands. Built decades ago, these systems are deeply intertwined with outdated processes, creating substantial barriers to scalability, innovation, and customer satisfaction.
As the competition intensifies and customer expectations rise, today’s insurers face mounting pressure to evolve. Yet, despite the clear limitations of legacy insurance technology, a staggering 74% of insurers continues to rely on outdated legacy systems, hesitating to pursue modernization initiatives due to perceived risks.
According to Gartner’s CIO Survey, approximately 70% of IT budgets are consumed by maintaining legacy infrastructure, leaving little room for investment in innovation and growth. While the industry moves toward digital transformation, many insurers remain tethered to aging mainframes that increasingly represent liabilities rather than assets.
Moreover, a staggering 90% of businesses report being held back in their digital transformation efforts due to outdated insurance technology, preventing organizations from capitalizing on new opportunities.
However, in today’s fast-paced insurance environment, clinging to familiar systems is an obstacle to long-term success. This tension between tradition and transformation highlights the urgent need for modernization. Let’s explore the challenges legacy systems present—and the opportunities that lie in embracing change.
The True Cost of Inaction: Core Legacy Systems in Insurance and Their Challenges
As the industry grapples with the challenges posed by legacy insurance systems, the implications of inaction become increasingly evident. Here are a few areas where the cost implications are the highest:
The Knowledge Gap
Many legacy applications are written in archaic programming languages like COBOL, which are becoming increasingly difficult to maintain as the pool of skilled programmers dwindles. With 60% of mainframe experts nearing retirement age, companies face a critical knowledge gap that threatens their operational continuity and innovation potential. This loss of expertise not only jeopardizes the maintenance of existing systems but also hinders the ability to implement necessary upgrades and transformations.
The Growing Cost of System Maintenance
Legacy systems, particularly those built on aging mainframes, consume vast amounts of Million Instructions Per Second (MIPS), which directly correlates to inflated operational costs. As the demand for processing power rises, so do the costs associated with maintaining these systems. For instance, the price of MIPS can range from $1,000 to $4,000 per million instructions, making it a significant expense for companies that rely heavily on mainframe technology.
Moreover, the licensing fees for software tools that support these legacy systems add another layer of financial strain. Over a decade, these costs can accumulate to approximately $9 million, encompassing not just MIPS but also labor maintenance and application upkeep. This is how the insurance processes consume MIPS :

The Complexities of Mergers and Acquisitions
The insurance industry has been significantly influenced by numerous mergers and acquisitions (M&A), resulting in a complex network of systems and platforms. This fragmentation complicates integration efforts and creates technical debt, trapping insurers in a cycle of stagnation that makes modernization both urgent and challenging.
International brokers face particular difficulties during post-acquisition integration, often uncovering a tangled web of disparate systems and inconsistent data structures. Consequently, multiple instances of policy, underwriting, and claims platforms operate in silos, leading to operational inefficiencies and hindering a unified customer experience.
The Surge in the Technical Debt
1. System Rigidity and Limited Agility
Legacy systems are typically characterized by tightly coupled architectures that resist change and innovation. This inflexibility makes it challenging to respond to market demands and implement new features quickly, putting insurers at a competitive disadvantage.
2. Data Limitations and Analytics Challenges
The static reporting capabilities of legacy systems severely limit insurers’ ability to derive meaningful insights from their data. This challenge is compounded by data quality issues and limited granularity, making it difficult to implement modern analytics solutions that could drive better decision-making.
3. AI Implementation Roadblocks
The complexity of legacy systems creates significant barriers to implementing AI-based solutions. This is particularly concerning given that AI-driven claims processing can reduce settlement times by 30-40%, representing a massive opportunity cost for insurers still running on legacy platforms.
The Case for Change: Business Benefits of Modernizing Insurance Legacy Systems
Modernizing legacy systems in the insurance industry offers transformative benefits, addressing inefficiencies, improving customer satisfaction, and enabling insurers to stay competitive in a rapidly evolving market. Below is a cohesive overview of eight key advantages of legacy system modernization:
1. Increased Operational Efficiency
Legacy insurance systems often require significant manual intervention, slowing processes like policy issuance, claims handling, and customer service. Modern systems streamline operations by automating manual tasks and reducing inefficiencies.
For example, Allianz Direct implemented a cutting-edge platform with AI-driven loss assessment, enabling customers to complete claims in just 60 seconds by uploading photos and documents. This innovation reduced operational costs by 50% and boosted customer satisfaction by 90%. Automation and digital workflows also free employees to focus on strategic tasks, improving productivity and reducing error rates.
2. Improved Data Accessibility and Decision-Making
Legacy systems often operate in silos, limiting access to real-time, comprehensive data. Legacy modernization integrates systems, enabling seamless data flow across departments. This allows insurers to:

Modern platforms also allow insurers to expand into new markets or launch new product lines without the extensive costs associated with legacy infrastructure upgrades.
5. Stronger Security and Regulatory Compliance
Insurers are increasingly aware of the critical importance of cybersecurity, especially as many have faced significant security breaches themselves. For example, several major insurance companies have reported cyber incidents that compromised sensitive customer data, highlighting the urgent need for robust security measures. This growing awareness is reflected in the rapid expansion of the cyber insurance market, which has nearly tripled in size over the past five years, as insurers seek to protect themselves and their clients from the rising threat of cyberattacks.
Archaic systems are more vulnerable to cyberattacks and often struggle to meet evolving regulatory requirements. Modernized systems offer:
- Improved compliance with industry regulations, reducing the risk of penalties and reputational damage.
- Advanced security features, such as real-time threat monitoring and encryption.
6. Higher Gross Written Premiums and Ecosystem Expansion
Modernized systems empower insurers to accelerate innovation and significantly reduce the time-to-market for new products, ultimately driving higher gross written premiums. For example, consider the difference in timelines for product rollouts in life insurance. If rollouts through traditional methods using legacy technology take 3 to 9 months, a modern composable architecture can streamline this process, reducing the rollout time to 8 to 12 weeks. This shift not only enhances operational efficiency but also allows companies to adapt more quickly to changing market demands and customer preferences. Additionally, APIs facilitate the integration of business partners, customers, and insurtechs, allowing insurers to expand their ecosystems. This integration opens up new distribution channels and markets, enhancing overall competitiveness in the industry.
