## 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. [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 Limits

Chubb underwrites Cyber ERM and lists first-party response, interruption, data recovery and extortion, plus third-party privacy, network, payment-card and regulatory cover. Social engineering and other cyber-crime grants are available by endorsement. Marsh McLennan Agency describes cyber liability and risk strategy but does not list these grants. Ask Marsh McLennan Agency which first-party, third-party and crime components are in the proposal. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Security Services and Eligibility

Chubb offers a Widespread Event Endorsement with separate limits and retentions, a tailored ransomware endorsement, and a 45-day patching grace period under its Neglected Software Exploit Endorsement. Marsh McLennan Agency’s overview does not describe these options or conditions. A buyer managing legacy systems should ask what patch deadlines and systemic-event terms apply to the Marsh McLennan Agency quote. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Buying and Incident Support

Chubb provides a 24/7 hotline, Cyber Alert app, threat intelligence and vulnerability outreach. It offers digital quoting through Cyber Central or Marketplace for risks under $100 million in revenue. Marsh McLennan Agency routes prospects to an adviser and does not state a quote path. Compare incident support, carrier identity and application requirements. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

## What to Confirm in Cyber Insurance Quotes

- Ask Chubb how the systemic-event, ransomware and patching endorsements change limits and retentions. Ask Marsh McLennan Agency for its response hotline, vulnerability services and specific cyber-crime endorsements. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")
