What Are the Key Differences Between AIG and Gallagher Tech E&O Insurance?

Coverage design and fit

AIG describes claims alleging errors or omissions in technology-service performance, including third-party economic loss. Gallagher describes one policy combining professional-services E&O with cyber perils such as data breaches, ransomware, and privacy violations. Companies seeking both exposures in one placement can ask Gallagher how the two sections share limits; those seeking E&O alone should ask AIG whether its quoted form stands separately. [2] [4]

Eligibility, services, and placement

Gallagher places coverage with outside carriers and reports serving clients from startups to global enterprises, backed by a digital suite for analytics, submissions, and certificates. AIG says its professional-liability claims team includes in-house and third-party experts. The buyer should separate Gallagher’s brokerage tools from AIG’s claims function when comparing service contacts. [2] [4]
