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. [8](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [9](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 Audience

Heffernan says cyber policies it arranges can cover data recovery, legal fees, notification and business interruption, with access to IT forensics and public-relations advisers. Marsh McLennan Agency describes cyber liability and risk strategy but does not enumerate coverage or response resources. Ask Marsh McLennan Agency who coordinates forensic and communications support after an incident. [4](https://www.heffins.com/business-insurance/cyber-insurance/ "Cyber Security Insurance") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Eligibility and Risk Review

Heffernan’s cyber risk team assesses exposure, shops the market and guides coverage selection before binding. Marsh McLennan Agency invites organizations to speak with an adviser or specialist but does not detail a pre-bind assessment. For a business storing sensitive data or relying on digital operations, ask what controls the broker will review and how it compares carrier options. [4](https://www.heffins.com/business-insurance/cyber-insurance/ "Cyber Security Insurance") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Application and Support

Heffernan says cyber can fit businesses of any size handling sensitive information and names healthcare, finance, retail and technology. Marsh McLennan Agency’s exact eligibility is placement-specific. Share your data types, security measures and outage dependency with both advisers to confirm appetite and limits. [4](https://www.heffins.com/business-insurance/cyber-insurance/ "Cyber Security Insurance") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")
