## Research Scope and Use

Use this comparison to evaluate At-Bay and Mylo for Cyber Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Mylo says cyber coverage can often be added to a Business Owner's Policy depending on the carrier, while At-Bay sells cyber as a dedicated policy with InsurSec security tiers rather than describing a BOP bundling option.

## Key Differences in Cyber Insurance

### Bundled Into a BOP vs Sold as Its Own Policy

Mylo says cyber insurance can often be added to a Business Owner's Policy depending on the carrier, alongside general liability, property and business interruption coverage.

Mylo says cyber insurance can often be added to a Business Owner's Policy depending on the carrier, alongside general liability, commercial property and business interruption. [9](https://choosemylo.com/business/product-cyber "Cyber Insurance") (Evidence: Company-reported; scope: Cyber insurance product page "Add cyber to your Business Owner's Policy (BOP)" section..)

At-Bay's cyber page does not describe a BOP bundling option; it sells cyber as a dedicated policy with optional InsurSec security tiers instead. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights")

### A Small-Business Statistic vs Published Appetite Ceilings

Mylo cites its own figure that more than two-thirds of small businesses have experienced a cyberattack to argue for the coverage, without publishing a revenue ceiling. [9](https://choosemylo.com/business/product-cyber "Cyber Insurance") At-Bay instead publishes specific appetite ceilings, writing primary and excess cyber for businesses up to $5 billion in revenue and $10 million in limits. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights")

### A Named Security Platform vs No Described Service

At-Bay includes its Stance platform, with vulnerability monitoring and a fraud-defense sub-limit, at the base tier of every policy. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") Mylo's cyber page does not describe a comparable security-monitoring service; it focuses on coverage description and BOP packaging instead. [9](https://choosemylo.com/business/product-cyber "Cyber Insurance")

## What to Confirm in Cyber Insurance Quotes

- Ask Mylo whether your quote is a standalone cyber policy or a BOP endorsement. [9](https://choosemylo.com/business/product-cyber "Cyber Insurance")
- Ask At-Bay whether your account would be issued on At-Bay Specialty Insurance Company paper or placed with another carrier. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [5](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper")
- Confirm which InsurSec tier and MDR subscription cost apply to your At-Bay quote. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights")
- Get the actual limit and retention from Mylo; its page does not publish standard figures. [9](https://choosemylo.com/business/product-cyber "Cyber Insurance")
