[1](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [6](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview")

## What Are the Key Differences Between At-Bay and Cowbell Tech E&O Insurance?

### Higher-Limit Tech E&O vs One Policy for E&O and Cyber

At-Bay writes Tech E&O as its own line, publishing limits up to $10 million for businesses with revenue up to $5 billion, and counts service credits you owe customers as payable damages. Cowbell's Prime Tech combines Tech E&O and cyber in one policy for tech businesses with up to $1 billion in revenue, with limits up to $5 million plus another $5 million through Prime Tech Plus follow-form excess. Both describe broad breach-of-contract and IP infringement cover and say they don't exclude guarantees, consequential damages or breached warranties. Choose At-Bay if you need more than $5 million of primary E&O or have over $1 billion in revenue; choose Cowbell if you want E&O and cyber in a single policy. [1](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [6](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview")

### Automated Broker Quotes vs Agent-Sold Surplus Lines

At-Bay takes submissions by email or through its Broker Platform, where automated quotes stop at $100 million in revenue and $3 million in limits; above that, expect underwriter review. Cowbell sells Prime Tech through agents as a surplus-lines policy (fewer state protections) in all 50 states. [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [1](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

### Stance Platform vs Resiliency Services and Training

At-Bay includes its Stance security platform with Tech E&O and sells managed detection and response separately through At-Bay Security, LLC. Cowbell adds Co-Pilot underwriting support, Resiliency Services, Connectors and free Wizer security training. [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [1](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
