It serves industrial and commercial clients with equipment protection, inspection services, and related risk management solutions, and traces its roots to boiler inspection and insurance services before expanding into a comprehensive specialty insurance franchise.

The company operates as a wholly-owned subsidiary of Munich Re Group, one of the world's largest reinsurance and insurance companies, and is grouped within Munich Re Specialty. HSB's product portfolio spans equipment breakdown insurance, specialty insurance, reinsurance, engineering inspections, and engineering consultancy — including energy and refining consulting via HSB Solomon Associates.

HSB's revenue model is built on insurance premiums, reinsurance cessions and assumed premium, and engineering inspection and consulting fees. Its go-to-market is anchored by Munich Re's global distribution and capital base; Munich Re Group reported a €1.7bn net result in Q1 2026, evidencing the scale of the parent platform supporting HSB. No standalone HSB revenue, headcount, premium volume, or pricing detail is disclosed in the available inputs.
