[Human-readable page](https://spot.insure/compare/biberk-vs-cna) # biBerk vs CNA Compare biBerk’s direct small-business route with CNA for a small business comparing an online direct seller with a commercial insurer that asks buyers to work through an agent. ## Before You Quote Ask each provider about eligibility, the issuing insurer, policy wording, limits, retentions, exclusions and costs for your business. ## Highlights CNA asks small-business buyers to work with an agent, while biBerk describes a direct online route. Both offer common business lines, so compare the actual CNA operating insurer, agent support and policy forms against the biBerk quote.

If that work is needed, collect the company's task, known deadline, current broker, and open questions for a [free consultation](https://spot.insure/pricing.md). The company decides what to buy; Spot does not automatically bind coverage. ## Key Differences Between biBerk and CNA ### Channel and Insurer Roles biBerk sells directly to small businesses. CNA directs small-business buyers to an agent, who provides the access and service route for its commercial policies. [1](https://www.biberk.com/about-biberk "About biBerk | Making Small Business Insurance Simple") [3](https://www.biberk.com/ "Small Business Insurance From biBerk | Get A Quote Online") [2](https://www.biberk.com/disclosures "Small Business Insurance From biBerk | Read Disclosures") [17](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") ### Coverage and Business Fit The current catalogues both list Business owner’s policy, General liability, Workers’ compensation. Shared labels make these useful lines to request side by side; they do not show that limits, exclusions, deductibles or forms match. biBerk offers common small-business policies and describes cyber as an add-on to certain base policies. CNA’s coverage catalogue and product descriptions should be checked against the specific exposure you are buying for, especially business owner’s policy. [11](https://www.biberk.com/small-business-insurance/general-liability-insurance "General Liability Insurance From biBerk | Get A Quote Today") [6](https://www.biberk.com/small-business-insurance/business-owners-policy "Get A biBerk Business Owners Policy | Fast Online Quote") [12](https://www.biberk.com/small-business-insurance/workers-compensation-insurance "Workers’ Compensation Insurance From biBerk | Get A Quote") [23](https://www.cna.com/products/cna-connect "CNA Connect Small Businessowners Policy (BOP) | CNA Insurance") [33](https://www.cna.com/products/general-liability "Commercial General Liability Insurance | CNA Insurance") [41](https://www.cna.com/products/workers-compensation "Workers’ Compensation Insurance | CNA Insurance") [5](https://www.biberk.com/small-business-insurance/cyber-insurance "Cyber Insurance & Data Breach Coverage for Business | biBerk") ### Application and Ongoing Service biBerk lets eligible buyers enter business details, select coverage and pay online. CNA tells small-business buyers to work with an agent; ask the agent what information CNA needs and who will present the quote. [4](https://www.biberk.com/support "biBerk Support | Small Business Insurance") [17](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [3](https://www.biberk.com/ "Small Business Insurance From biBerk | Get A Quote Online") ## What to Confirm in Quotes - Can both providers quote Business owner’s policy, General liability, Workers’ compensation with the same limits, deductibles, exclusions and policy period? Ask for the forms with each proposal. - Who is the licensed producer or broker on each quote, which insurer issues each policy, and where do you send a claim notice? Ask the CNA agent to identify the issuing CNA company and policy service contact; compare that agent route with biBerk's direct application for the same limits. [17](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [48](https://www.nerdwallet.com/business/insurance/learn/manufacturers "Manufacturer Insurance: Best Companies, Costs and Coverages") - What premium, taxes, fees and commissions apply to the exact risk and term? Do not compare sample prices or payment methods without the same limits and coverage terms. ## Compare Services What each provider documents about the services you may need. | Criteria | biBerk | CNA | | --- | --- | --- | | Business role | biBerk says it sells small-business insurance directly without an insurance broker. This is its company-reported channel description. Its California/Massachusetts notice names four insurers collectively as issuing most policies and lists each insurer’s licensed jurisdictions, but does not identify the insurer for a particular transaction, product, or policy or guarantee product availability in a jurisdiction.
