Key Differences in Cyber Insurance

A Named Insurer Per Product vs None Named

Cowbell says Prime 100 and Prime 100 Pro paper is provided by Palomar Specialty Insurance Company, and Prime One by Chaucer Specialty Insurance Company, so the insurer varies by which Prime product is placed.

Cowbell says Prime 100 and Prime 100 Pro paper is provided by Palomar Specialty Insurance Company (AM Best A rating), Prime 250 by Palomar Specialty Insurance Company and Chaucer Insurance Company, and Prime One by Chaucer Specialty Insurance Company; the insurer therefore varies by which Prime product is placed. 10,12,13Company-reported. Footer/underwriting statements in each product PDF.

At-Bay's current cyber product page does not name an insurer for a placement. 3 5

AI and Quantum Coverage vs Tiered Ransomware Terms

Cowbell's Prime One product adds affirmative coverage for AI-incident and quantum-computing-incident exposures for organizations with more advanced digital risk. 10 13 At-Bay instead structures its emerging-risk protection around InsurSec tiers, where a reduced ransomware retention and a zero-hour waiting period apply once a buyer adds a managed detection and response subscription. 3

Minutes-to-Bind vs a Capped Automated Platform

Cowbell says agents can quote, bind and issue Prime 100 policies in less than five minutes, and Prime 100 Pro needs only six underwriting questions for accounts under $50 million in revenue. 10 11 At-Bay's Broker Platform gives automated quotes only for accounts under $100 million in revenue and $3 million in limits; larger accounts are submitted by email to its underwriting team instead. 3 3

What to Confirm in Cyber Insurance Quotes

  • Ask Cowbell which Prime product and named insurer applies to your business's revenue band. 10 11 12 13
  • Ask At-Bay whether your account would be issued on At-Bay Specialty Insurance Company paper or placed with another carrier. 3 5
  • If your business has AI or quantum-computing exposure, ask each how its policy terms apply to that exposure: Cowbell's affirmative coverage and At-Bay's tiered ransomware terms. 10 13
  • Get the actual limit and retention on both quotes; compare them against Cowbell's published per-product limit figures. 11 13 14 3

CriteriaAt-Bay Cyber InsuranceCowbell Prime Cyber Insurance (Prime 100, Prime 100 Pro, Prime 250, Prime One, Prime Plus)
Role in This Line

At-Bay places cyber insurance through its disclosed producer, At-Bay Insurance Services LLC, which is licensed as an insurance producer in all 50 states. At-Bay says eligible new excess-and-surplus (E&S) cyber business has been written on its own carrier paper, At-Bay Specialty Insurance Company, since August 2023. 4,5Company-reported. Producer role from the current license page; carrier role from a 2023 transition announcement, not confirmed for every current cyber quote.

Cowbell operates as an insurance agency that markets its own named 'Prime' cyber product line, rather than distributing another carrier's off-the-shelf policy under its own brand. 10,12,13Company-reported. Product overview PDFs for Prime 100, Prime 100 Pro, Prime 250, Prime One and Prime Plus.

Issuing Insurer

The current cyber product page does not name an issuing insurer. At-Bay's 2023 announcement says new E&S cyber business is quoted on At-Bay Specialty Insurance Company paper, but that is a historical statement, not a per-quote disclosure. 3,5Company-reported. Cyber product page checked today names no insurer; the carrier-transition release is dated August 2023 and does not cover every current state or account.

Cowbell says Prime 100 and Prime 100 Pro paper is provided by Palomar Specialty Insurance Company (AM Best A rating), Prime 250 by Palomar Specialty Insurance Company and Chaucer Insurance Company, and Prime One by Chaucer Specialty Insurance Company; the insurer therefore varies by which Prime product is placed. 10,12,13Company-reported. Footer/underwriting statements in each product PDF.

Product-page InsurSec and footnote descriptions; MDR pricing is described as estimated and subject to change.

Cowbell says every Prime policy includes Cowbell Factors risk ratings, Cowbell Resiliency Services, Cowbell Insights guidance, Cowbell Connectors integrations with cloud/security providers, and complimentary Wizer cybersecurity-awareness training with unlimited seats in the first policy year. 10,12Company-reported.
