EIS Group
EIS Group (EIS Ltd) is a United States core-systems vendor for insurance, founded in 2008 out of Exigen Insurance Solutions and headquartered in San Francisco, California. EIS sells the EIS Platform and EIS OneSuite — a cloud-native, microservices core suite covering customer management, policy administration, billing, and claims — across group benefits, property and casualty / general, protection, life and annuities, and pet insurance. EIS markets itself as API-first and claims thousands of open REST APIs (1,100 digital APIs announced in 2019, 9,000+ claimed for OneSuite) fronted by the EIS DXP API middleware, but none of that surface is public. There is no self-serve developer portal on eisgroup.com; the documentation host docs.eisgroup.com answers HTTP 401 behind an HTTP Basic realm named "EIS Group Users", so the entire API reference is a customer/partner login wall. No OpenAPI, Swagger, GraphQL, AsyncAPI, or public Postman collection could be retrieved. The only public code EIS ships is two open-source GitHub repositories (kraken-rules, ui-render), which are libraries rather than APIs. ACORD is attested only indirectly — an analyst evaluation hosted on eisgroup.com states the system integrates using "web services, APIs, RESTful APIs, ACORD and certified ACORD" — with no ACORD artifacts, AL3 mappings, or IVANS/agency-download detail published. What EIS does publish is a substantial certification posture — a certified MACH Alliance membership (Microservices, API-first, Cloud-native SaaS, Headless) and a full ISO stack covering 27001, 27701, 22301, 27017, 27018, 27035-1, 12207, 15288, 25000 and ISO/IEC 42001, which EIS announced in June 2025 as the first cloud-native insurance core platform provider to obtain. One first-party package is public, eis-ui-render on npm. This is the canonical United States core-systems posture — the APIs exist and are sold, but they are reachable only through a licensed implementation.
