About Our Company


Traditional Stop Loss

Our underwriting expertise enables us to accurately evaluate networks of all sizes, from regional networks, to national Preferred Provider Organizations, and everything in between. From there, we can curate a stop loss solution built around any traditional arrangement. Additionally, iiSi specializes in reference-based pricing and similar non-traditional cost containment approaches to effectively control health care costs.

Integrated Stop Loss

Self-funding used to be viable only for larger employer groups with deep enough pockets to withstand the fluctuations in claim expenses throughout the plan year. With iiSi's Integrated Stop Loss product, employer groups with as few as 15 lives can enjoy the advantages of self-funding and limit their risk exposure with a predictable, level monthly payment.

Product Enhancements

At iiSi, we understand that employer stop loss is not a one-size-fits-all product. With our product enhancement options, we have the flexibility to further enhance a stop loss solution with additional benefits or coverage modifications to tailor personalized coverage that fits an employer group's financial objectives and risk tolerance.
