At-Bay

At-Bay is an InsurSec company that combines cyber insurance with proactive security monitoring for businesses. Headquartered in New York with offices in San Francisco and Tel Aviv, At-Bay underwrites Surplus Cyber, Surplus Tech E&O, and Surplus Miscellaneous Professional Liability (MPL) coverage and bundles them with the At-Bay Stance security platform (advisory, fraud defense, incident response) and 24/7 Managed Detection and Response (MDR) across endpoint, email (MXDR), and multi-vector surfaces. At-Bay distributes through a network of independent brokers and partners and exposes a production-grade REST Partner API (v2) that lets brokerage platforms, digital distributors, and agency management systems quote, customize, bind, renew, retrieve documents, and receive webhook callbacks for the full policy lifecycle. Demo environment at api-demo.at-bay.com lets partners integrate without going through Broker of Record clearance.
