## What Is Cyber Insurance?

Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. [10](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [11](https://www.aig.com/content/dam/aig/america-canada/us/documents/business/cyber/cyberedge-wording-sample-specimen-form.pdf "CyberEdge specimen policy")

## Key Differences in Cyber Insurance

### What a coverage summary lets you compare

Berkshire Hathaway Specialty Insurance names direct breach response, extortion expenses, third-party exposures, and interruption after a network-security failure. Marsh McLennan Agency describes arranging cyber liability alongside a cyber-risk management strategy, but its reviewed summary does not enumerate matching cost categories. Ask the adviser to map the proposed wording to the losses BHSI lists so you can compare actual protections rather than labels. [5](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy") [9](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Product form and route to a quote

Berkshire Hathaway Specialty Insurance describes a standalone Network Security & Privacy policy and blended E&O/Cyber forms. Marsh McLennan Agency invites organizations to contact an adviser or specialist to discuss placement. The practical choice is between evaluating a named form and beginning with an adviser-led design conversation; neither route alone establishes the final insurer, limits, or exclusions. [5](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy") [9](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

## What to Confirm in Cyber Insurance Quotes

- Ask the Marsh McLennan Agency adviser to identify covered response, extortion, interruption, and third-party expenses in the actual form; request BHSI’s sublimits and conditions for the corresponding categories. [9](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") [5](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")
- Ask both providers to name the issuing insurer and proposed form, and clarify whether cyber is standalone or blended with E&O. [9](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") [5](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")
