Make accurate decisions with risk insights at the point of need, through Guidewire Industry Intel, HazardHub, Predict, and Cyence.

Guidewire provides the platform to handle business flexibly, with built-in London Market messaging so you can negotiate effectively, enhance relationships, and grow business. Empower your service teams with ProNavigator inside PolicyCenter, which puts complex policy answers on screen instantly so your team never has to transfer, hold, or search through separate chatbots.
- Enable swift assessment and settlement of claims via ECF Write-Back or manually. Segment and triage claims with business rules that you control; identify high-severity claims and assign work quickly to the appropriate adjuster.
