[8](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [11](https://www.coverdash.com/coverage "Coverage Hub") [12](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Trigger and Form Enhancements

biBerk says its umbrella can respond after a covered claim exceeds an applicable existing liability limit. CNA describes forms designed to align with most underlying terms and lists key-employee replacement, crisis management, waiver of subrogation, and most-favorable venue as built-in enhancements. For your business, the key comparison is the wording attached to your scheduled primary policies and whether CNA’s listed features appear in the quote. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [7](https://www.cna.com/products/umbrella "Umbrella Insurance and Excess Liability Insurance | CNA Insurance")

### Keep the Underlying Schedule in View

biBerk says protection only applies to coverages included in the underlying policy; without commercial auto underneath, auto claims are not added. CNA says its forms align with most underlying conditions, but the reviewed record does not spell out which policies or attachment points a specific placement requires. Ask both providers to map the excess layer to each policy you want protected. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [7](https://www.cna.com/products/umbrella "Umbrella Insurance and Excess Liability Insurance | CNA Insurance")

CNA also describes flexible underwriting backed by more than 50 years of commercial umbrella/excess experience; biBerk’s reviewed details focus on online or phone access and the underlying policy relationship.
