## 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. [10](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [11](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 optional security tiers

At-Bay lists business interruption, system failure, social engineering, invoice manipulation, cryptojacking and bricking coverage. Its optional InsurSec tiers change ransomware and financial-fraud retentions and sublimits, with higher tiers requiring a separately purchased MDR service. Zurich says it writes primary and excess policies; ask its quote to itemize comparable extensions and limits. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [9](https://www.zurichna.com/insurance/cyber "Cyber Security Insurance and Coverage | Zurich Insurance")

### Security support and incident access

At-Bay says every policy includes Stance tools such as vulnerability monitoring, advisory, tabletop exercises and training, and provides a named breach-coach line with an in-house claims team. Zurich directs customers to claims and incident-response resources and offers a complimentary onboarding session. Compare who answers after an incident and which services are included versus separately priced. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [9](https://www.zurichna.com/insurance/cyber "Cyber Security Insurance and Coverage | Zurich Insurance")

### Appetite and buying route

At-Bay says it writes businesses up to $5 billion in revenue and limits up to $10 million, while automated broker quotes have narrower thresholds of $100 million revenue and $3 million limits. Zurich’s reviewed record distinguishes small or midsize from large or global customers and offers primary or excess placements. Ask both for the actual underwriting route and available limits for your account. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [9](https://www.zurichna.com/insurance/cyber "Cyber Security Insurance and Coverage | Zurich Insurance")

## What to Confirm in Cyber Insurance Quotes

- Compare each fraud, ransomware and business-interruption limit; price At-Bay’s required MDR separately where applicable. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance Coverage & Policy Highlights") [9](https://www.zurichna.com/insurance/cyber "Cyber Security Insurance and Coverage | Zurich Insurance")
- Ask for the incident contact, included security services and whether the Zurich proposal is primary or excess.

## At-Bay Reviews

Review Score: 9.5 / 10 from 2 rated sources, equally weighted.

At-Bay’s public review evidence is thin: one old G2 review and a BBB complaint record. It is not enough to judge day-to-day service or claims handling.

- BBB: BBB rating A (A+ to F). At-Bay identity; US commercial insurance review/satisfaction evidence sought on BBB. Period: accessed 2026-09-25. Checked 2026-09-25. [At-Bay | BBB Business Profile](https://www.bbb.org/us/ca/mountain-view/profile/insurance-companies/at-bay-1216-1000025767)
- G2: G2 star rating 4.5 (5 stars); 1 reviews. At-Bay company/product feedback; G2 seller profile identifies its offering as cybersecurity insurance and lists San Francisco headquarters. Not an insurance-policy claims or commercial-buyer satisfaction study. Period: review dated 2020-09-21. Checked 2026-09-25. [At-Bay seller profile and reviews](https://www.g2.com/es/sellers/at-bay)
