## What Are the Key Differences Between Alliance Risk and At-Bay Professional Liability (E&O) Insurance?

### What You Can Compare Before Applying

At-Bay publishes a $5 million maximum limit for its Miscellaneous Professional Liability policy and lists its coverage features, so you can check whether the stated ceiling could meet your needs before approaching a broker. [2](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

Alliance Risk describes a broker-led service, including risk-specific underwriting input and carrier partnerships, but its page gives illustrative cost ranges by firm size rather than limits. You will need an actual quote to see the available limit and insurer. [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

### What the Policy Describes

At-Bay lists automatic coverage for acquired subsidiaries, independent contractors, disciplinary-proceedings defense, a duty to defend and an 80/20 hammer clause. These details give you specific terms to ask about when comparing quotes. Alliance Risk describes protection for negligent acts, breach of contract, misrepresentation and missed deadlines, while directing bodily injury, intentional wrongdoing and cyber incidents to other coverage. [2](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

### How You Get a Quote

The reviewed At-Bay workflow is its Broker Platform for insurance professionals to create, customize and bind quotes; the page does not describe a direct retail application. Alliance Risk offers a quote request and describes broker services, but does not list a submission checklist. If you need coverage quickly, ask both how long underwriting will take and what documents they need.
