Key Differences in Tech E&O Insurance

Coverage description and risk services

AIG describes Technology Services E&O as responding to allegations of errors or omissions in technology-service performance, including third-party economic loss. CNA describes its Technology E&O as addressing contractual requirements and reducing coverage gaps, and also identifies privacy and data-protection risk-control resources for technology clients. A buyer should map customer contract obligations to the offered form and ask what risk-control help is attached to the CNA placement. The public descriptions do not establish exact policy terms. 3 7

Claims handling

CNA calls out responsive claims support for its technology clients. AIG describes a professional-liability claims team with in-house professionals and third-party experts that collaborates with clients, while noting those services are not a guaranteed result for a technology E&O claim. These descriptions give buyers different levels of detail about the claims function; obtain the reporting contacts and escalation process before binding. 7 3

What to Confirm in Tech E&O Insurance Quotes

  • Ask CNA which contractual requirements its form addresses and what privacy risk-control services are available to your account. 7
  • Ask AIG for the technology E&O claim-reporting route and how third-party experts participate. 3
