## 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. [11](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [12](https://www.aig.com/content/dam/aig/america-canada/us/documents/business/cyber/cyberedge-wording-sample-specimen-form.pdf "CyberEdge specimen policy")

## What Are the Key Differences Between At-Bay and CNA Cyber Insurance?

### Coverage and Service Structure

The named service sets overlap around preparation but are not identical in the records. At-Bay separately prices managed detection and response subscriptions, and its optional InsurSec tiers change fraud and ransomware terms. CNA’s cited offering claims do not publish comparable tiered retentions, fraud sublimits or MDR pricing. A buyer should distinguish included policyholder access from add-on subscriptions and verify services in the quote. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [10](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance")

### Eligibility and Quote Questions

At-Bay says it writes primary and excess cyber for businesses up to $5 billion in revenue and $10 million in limits, while automated Broker Platform quotes are limited to $100 million revenue and $3 million. CNA’s cyber claim set focuses on EPS Plus and Epack 3 segments without a comparable public ceiling. At-Bay also describes an in-house claims team and breach-coach contact; the CNA record names response vendors, not an equivalent claims workflow. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [10](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance")

## What Should You Confirm in At-Bay and CNA Cyber Insurance Quotes?

- Ask At-Bay which InsurSec tier and MDR subscription are quoted and which carrier applies; ask CNA which form and incident-response vendors are included. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [10](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance")
- Compare ransomware waiting periods, financial-fraud retention, system-failure interruption, limits and claims contacts.
