What Is Cyber Insurance?

Key Differences in Cyber Insurance
At-Bay Lists Specific First-Party and Fraud Coverages
At-Bay identifies direct and contingent business interruption, system failure, social engineering, invoice manipulation, cyber extortion and reputational-harm costs among its cyber features. Nationwide describes expenses associated with cyberattacks and data breaches but does not enumerate these protections in its overview. If outage or fraudulent-payment losses are central to your risk, match each item to the policy wording and check whether it carries a separate sublimit. 3 10
At-Bay Includes a Named Security Platform
At-Bay says every cyber policy includes Stance, with vulnerability monitoring, vCISO advice, tabletop exercises and security-awareness training; endpoint or email detection and response costs extra. Nationwide’s reviewed page offers a quote or agent contact and does not describe comparable policyholder security services. Ask Nationwide what services accompany its quote, and price At-Bay’s optional MDR separately if you need active monitoring. 3 10
Published Capacity Has Different Scopes
At-Bay says it writes primary and excess cyber for businesses up to $5 billion in revenue and limits up to $10 million, while its automated broker quotes are narrower: up to $100 million revenue and $3 million limits. Nationwide’s product overview publishes no universal limit or retention. Larger companies should distinguish At-Bay’s broader underwriting appetite from automated quote availability and obtain a specific Nationwide proposal to compare. 3 10
What to Confirm in Cyber Insurance Quotes
- Ask which At-Bay InsurSec tier and separately priced MDR services apply; ask Nationwide’s agent what security services, if any, accompany the proposed form. 3 10
- Confirm the named insurer, the offered limit and retention, and whether outage, invoice manipulation and social-engineering losses have sublimits or waiting periods. 3 10

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.[3][6][9]
