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.

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 the financial objectives and risk tolerance of your client.
