Cowbell suits small and midsize businesses seeking cyber options by company size, with technology E&O and Zurich management-liability options also available; firms needing broad commercial coverage should compare a full-service broker.

Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed.

Berkshire Hathaway Specialty Insurance instead targets private companies with at least $10 million in revenue and advertises portfolio limits up to $50 million. These routes have different access and scale assumptions; neither public page supplies a guaranteed quote.

Berkshire Hathaway Specialty Insurance’s fiduciary policy page names full settlor coverage, ACA gap protection, and fines and penalties. Buyers should ask both for the issuing company and form terms.

Ask Berkshire Hathaway Specialty Insurance whether your revenue qualifies and request its fiduciary allocation and settlor/ACA wording.
