What Professional Liability Insurance Covers

Also known as Errors and Omissions (E&O) insurance, professional liability covers claims that a mistake, omission, or negligent act in your professional services caused a client financial harm.

Legal Defense Costs

Pays attorney fees and court costs to defend against covered claims — even frivolous ones. Defense costs are often paid in addition to your policy limits.

Settlements & Judgments

Covers settlements you agree to and judgments awarded against you, up to your policy limits. Protects your personal and business assets from a single dissatisfied client.

Negligent Acts & Errors

Covers claims arising from a mistake, error, or omission in the professional services you delivered — the core of what E&O insurance protects.

Failure to Deliver Services

Covers claims that you failed to deliver a promised service or missed a critical deadline that caused a client financial loss.

Claims-Made Coverage

Professional liability is written on a claims-made basis — the policy in force when a claim is reported responds, not the one in force when the work was done. We help you manage retroactive dates.

Prior Acts Coverage

When you switch carriers, we negotiate prior acts coverage so there's no gap in protection for work you performed before the new policy started.

Why Professionals Choose CISA for E&O Insurance

Profession-Specific Markets

Different professions face different risks — and different carriers. We match your specific profession to the E&O market that understands it, from real estate and consulting to accounting and technology.

Retroactive Date Management

Switching carriers can create a coverage gap for past work. We negotiate prior acts coverage and align retroactive dates so your entire claims history stays protected.

Defense Outside Limits

We structure your policy so legal defense costs are paid in addition to your limits wherever the market allows — so a long, expensive defense doesn't eat the money meant to settle a claim.

Frequently Asked Questions

What is the difference between professional liability and general liability insurance?

General liability covers third-party bodily injury and property damage — physical harm. Professional liability (E&O) covers financial harm caused by a mistake or omission in your professional services. Most professional businesses need both, because general liability specifically excludes claims arising from your professional work.

Who needs professional liability insurance?

Any business that provides professional advice, services, or expertise for a fee needs E&O coverage — including consultants, real estate agents, accountants, insurance brokers, technology professionals, architects, engineers, marketing agencies, and many others. If a client could claim your work caused them a financial loss, you need it.

How much does professional liability insurance cost?

Cost depends on your profession, annual revenue, number of professionals covered, claims history, and limits selected. Typical policies range from $600 to $3,000 per professional per year. CISA shops 40+ carriers to find you the most competitive rate for your specific profession.

Does professional liability insurance cover cyber and data breach claims?

Not typically — cyber liability is usually a separate policy. Some E&O policies offer limited cyber endorsements, but for true data breach and ransomware protection, a dedicated cyber liability policy is strongly recommended. We'll help you coordinate both.
