## 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. [12](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [13](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

### Coverage and Limits

Coalition says breach-response expenses have a separate limit, while its policy also lists extortion, funds-transfer fraud and business interruption. Marsh McLennan Agency describes cyber liability and risk management but does not explain limit structure. Ask Marsh McLennan Agency whether forensic, notification and legal-response costs erode the same limit as other losses. [5](https://www.coalitioninc.com/cyber-insurance "Active Cyber Insurance") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Security Services and Eligibility

Coalition provides Control at no additional cost, including attack-surface and vendor monitoring, zero-day alerts and account security. Marsh McLennan Agency’s overview does not describe comparable monitoring. Coalition also buys through appointed brokers and underwriting considers security posture, operations and finances; ask Marsh McLennan Agency what risk assessment and security services accompany its placement. [5](https://www.coalitioninc.com/cyber-insurance "Active Cyber Insurance") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Buying and Incident Support

Coalition describes in-house claims and affiliated incident response, including a breach-response team and stolen-funds recovery support. Its admitted policies name Coalition Insurance Company, while surplus-lines placements use unaffiliated carriers. Marsh McLennan Agency’s overview does not identify insurer or claims contact; ask for those details before binding. [5](https://www.coalitioninc.com/cyber-insurance "Active Cyber Insurance") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

## What to Confirm in Cyber Insurance Quotes

- What separate breach-response limit and primary limit would Coalition quote, and which admitted or surplus-lines carrier applies? Ask Marsh McLennan Agency for its incident team, monitoring and claims contacts. [5](https://www.coalitioninc.com/cyber-insurance "Active Cyber Insurance") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")
