About professional liability
Professional liability, also known as errors and omissions (E&O), responds when a client claims your work caused them a financial loss: a missed step, an error in a filing, advice that did not hold up, or a service that fell short of what was promised. It pays the legal defense, which often costs more than the claim itself, plus any settlement or judgment. It is the line every business that sells expertise should carry.

How we use AI
AI helps our bonding team work faster. Our specialists still own every call.
For Professional Liability Insurance filings, AI helps our team find the right starting point quickly and reuse data you have already given us, so the work moves without extra effort from you. A licensed Cornerstone specialist reviews everything before it leaves our hands. Your information stays on our infrastructure, not in a public LLM.

Our models run on Cornerstone servers, not public chatbots. Your business information is not sent to a third-party LLM or used to train anyone else's product.
An Assistant, Not an Operator
AI helps our bonding team start their research in the right place and surface the resources to look at. Specialists vet what comes back and make the call.
Less Duplicate Work for You
Atlas figures out what data each form needs, then reuses what you have already given us so the same question does not come around twice. That is how approvals come faster.
