What is insurance platform as a service?

Insurance platform as a service is a cloud-delivered insurance technology model that gives carriers access to core platform capabilities without owning and maintaining the full infrastructure themselves. In practice, insurance PaaS often blends the managed delivery of SaaS with the configurability and extensibility insurers expect from a modern insurance platform.

Traditional insurance software usually sits on-premise or in heavily customized hosted environments. It may support core workflows, but it often requires lengthy upgrade cycles, custom hard-coding, infrastructure management, and plenty of IT effort just to keep the lights on. This model worked when insurance moved slower, but today, it turns every product change into a large project.

Insurance platform as a service is different. It’s typically cloud-native, modular, API-first, and vendor-managed. Cloud-native matters because the system is designed for the cloud from the start, not lifted from an old server, meaning it can support scale, faster deployment, better resilience, and continuous improvement.

The data layer is just as important. Legacy systems often trap data in silos across policy, claims, billing, customer, and third-party tools. A modern platform uses governed, fluid data to support real-time decisioning, analytics, automation, and AI. EIS OneSuite, for example, has an open, event-driven, real-time-responsive architecture designed to remove data silos across the insurance value chain, making data actually usable, and not just storing it.

What is an example of a platform as a service?

A clear example of the best insurance platform as a service model is a cloud-native insurance platform that supports policy administration, billing, claims, customer management, workflow automation, APIs, analytics, and compliance in one connected environment.

EIS OneSuite, as an example, is cloud-native, API-first, and modular, built to support insurers across group benefits, P&C, protection, and life insurance. Its platform foundation includes open architecture, event-driven operations, real-time responsiveness, business rules, workflows, security, user profiles, reporting, and customer-centric data management.

Insurance platform companies deliver these environments through the cloud, which means the vendor takes responsibility for platform availability, upgrades, maintenance, security patches, and ongoing enhancements. 

Scalability is also part of the value. Insurers need systems that can handle seasonal enrollment spikes, catastrophe-driven claims surges, new product launches, new distribution partners, and acquisitions. A cloud-native platform allows capacity and functionality to scale without forcing a full rebuild.

The best platforms also give insurers flexibility. They support phased transformation, so a carrier can modernize one business line, product family, workflow, or core domain at a time instead of attempting a risky “replace everything ASAP” migration.

What is the EIS Platform?

EIS Platform is a prominent example of insurance platform as a service for insurers that want a modern digital core without being boxed in by legacy architecture. It sits at the center of EIS OneSuite and provides the operational foundation for policy, billing, claims, customer, portals, data, workflows, rules, and integrations.

EIS Platform is modular, cloud-native, open, event-driven, and real-time-responsive. In practical terms, it allows insurers to configure products, automate workflows, connect third-party systems, create user experiences, and use data across the lifecycle without forcing every change through a maze of custom code. It has modern tooling for business rules, security, workflows, tasks, events, processes, configuration, and data extraction for analytics and reporting.

Its API capabilities are a key feature. It manages interfaces between front-end applications and back-end microservices, including EIS OneSuite components and third-party systems. It also supports APIs for persona-based self-service portals, helping insurers deliver tailored experiences for customers, brokers, sales reps, group members, and other users.

The platform also supports regulatory compliance and security through business activity monitoring, access control, encryption, audit readiness, compliance reporting, and configurable data protocols — helping monitor compliance adherence and generating detailed reports for internal and external audits.

For insurers evaluating the best insurance platform, this is the part worth noting: modern core technology isn’t only about processing transactions faster, but about creating the governed foundation where transactions, data, workflows, AI, and compliance can all move together.

What are some popular providers of insurance platform as a service, and what do they offer?

The insurance platform list for enterprise carriers often includes EIS, Guidewire, Majesco, and Duck Creek. Each provider brings a different approach to cloud delivery, core functionality, data, and insurance operations.

These insurance as a service companies all aim to help insurers modernize core operation, but the key evaluation factor isn’t simply, “Does it run in the cloud?” Instead, it’s, “Were they designed for cloud-native agility, governed data, open integration, and continuous innovation?”

EIS stands out as a winner, because it was built as a cloud-native, modular, API-first platform with an open, event-driven architecture that supports real-time operations across policy, billing, claims, and customer management. Because of this, it gives insurers the flexibility to launch faster, scale without major rework, and evolve their core without getting trapped in hard-coded dependencies.

Just as important, EIS is designed to make data fluid and governed rather than scattered across disconnected systems. This is important, because modern insurance runs on real-time visibility, not delayed reconciliation across silos. When data can move cleanly across the platform and ecosystem, insurers are in a much better position to automate workflows, improve customer experiences, support compliance, and feed AI with usable operational context instead of stale fragments.

EIS also supports the kind of open integration that insurers now need to compete. With API-driven connectivity, configurable workflows, and vendor-managed upgrades and maintenance, carriers can connect the systems they already rely on while keeping the platform current, making continuous innovation far more realistic. Instead of spending time managing infrastructure, patching custom workarounds, or untangling brittle integrations, insurers can focus on product development, operational efficiency, and customer value.

How do the features of PaaS for insurance differ from traditional software solutions?

PaaS insurance platforms differ from traditional software solutions in five major ways: flexibility, scalability, integration, upgrade cycles, and data usability.

Traditional insurance software often depends on rigid architecture and heavy customization. It may support policy or claims workflows, but adding new products, channels, rating models, compliance rules, or third-party integrations can require long development projects. In many cases, legacy and “modern legacy” systems rely on hard-coded integrations that slow the business down and make change expensive. EIS documentation describes modern legacy systems as difficult to integrate with newer solutions, and not built for the industry’s current pace of change or customer demand for digital experiences.

Insurance platform as a service is built for configuration, extension, and scale. A cloud-native platform can support modular deployment, so carriers can modernize in phases, meaning insurers can avoid the trap of a big-bang transformation. 

The upgrade model is another major difference. In traditional environments, insurers often own the burden of patches, version upgrades, infrastructure updates, testing, and compatibility work. With vendor-managed cloud platforms, the provider is responsible for maintenance and platform evolution, helping reduce IT burden on the insurer.

Finally, data fluidity is a huge win with these systems. Legacy systems often trap policy, claims, billing, and customer data in disconnected repositories, making AI and analytics harder because models need clean, current, governed data to produce useful results. A good insurance platform should support real-time, governed data flows across core domains, not force analytics teams to assemble puzzle pieces from various systems and spreadsheets.

EIS OneSuite is a cloud-native and AI-native platform centered around knowledge, reasoning, and execution: data and domain context, governed decision support, and secure execution through APIs, workflows, and real-time transactions.

Can you explain how APIs are used within these platforms to integrate with existing systems?

APIs are the connective tissue of a modern insurance platform. They allow core insurance systems to exchange data and trigger actions across CRM, billing, claims, policy administration, portals, marketing automation, analytics platforms, enrollment systems, fraud tools, payment providers, document systems, and third-party data sources.

In a platform environment, APIs help insurers avoid brittle point-to-point integrations. Instead of building a custom bridge every time a new system joins the ecosystem, insurers can use standardized, governed interfaces, supporting faster innovation and fewer integration headaches.

Open APIs are especially important for insurance platform companies because insurance is now an ecosystem business. Brokers, employers, customers, repair networks, health data providers, reinsurers, payment systems, insurtech partners, the internet of things (IoT), and regulatory reporting tools may all need to connect, depending on the lines of business an insurer sells. Without open integration, every new partnership becomes a bespoke technology project, creating a lot of work that wouldn’t be necessary with a truly modern insurance platform.

EIS OneSuite has thousands of APIs that support integration between its core system of PolicyCore, BillingCore, ClaimCore, and CustomerCore with proprietary and third-party systems. It’s also compatible with major CRM, marketing automation, analytics, and external policy, billing, and claims platforms for insurers who are leaning towards a more modular approach to digital transformation.

For carriers evaluating the best insurance platform as a service, API quality should be a buying criterion, since they determine how well the platform can connect to the insurer’s current stack and future innovations.

How do these platforms support regulatory compliance in the insurance industry?

Insurance platform as a service solutions support regulatory compliance by building governance, controls, auditability, security, reporting, and configurable workflows into the platform.

Insurance is regulated at every turn: data privacy, underwriting fairness, claims handling, billing accuracy, notices, consent, product filings, regional rules, audit requirements, and reporting obligations all need reliable controls. A modern platform helps by making compliance an embedded part of daily operations.

Governed data is central. If insurers can’t track where data came from, who accessed it, what changed, and which workflow acted on it, compliance goes out the window. Built-in audit trails and business activity monitoring help insurers see the “who, what, when, where, and why” behind operational events.

EIS Platform includes Business Activity Monitoring, where user activity is tracked, providing a full view of entities and changes, supporting corporate memory, accountability, performance monitoring, problem identification, and audit/compliance needs.

Automated reporting also helps. Cloud-native platforms can generate compliance reports, monitor adherence, and adapt workflows when new rules appear. EIS can configure data storage, processing, and transmission protocols based on policyholder location and regional guidelines, with reporting capabilities for internal and external audits.

Finally, security is a key part of compliance. Modern platforms typically include encryption, access control, activity monitoring, intrusion detection, vulnerability management, and patching. EIS has advanced monitoring, robust data encryption, access controls, firewall protection, security audits, anomaly detection, and patch management as part of its platform security approach.

For insurers reviewing an insurance platform list, compliance shouldn’t be treated as a simple checkbox — the best insurance platform is one that helps insurers prove what happened, govern what happens next, and adapt with ease when regulations change.

A cloud-native insurance platform as a service gives carriers the foundation to modernize core operations, connect ecosystems, improve customer experiences, support AI, and reduce the operational drag of legacy maintenance. It also gives insurers something they have needed for a long time: a core that can keep up with today’s market.
