Sourced limitations

Guidewire PolicyCenter

No publicly-sourced limitations recorded on the vendor card yet.

Insurity
  • Insurity is not plug-and-play; implementations typically require a third-party systems integrator, and budget planning must include data migration and ongoing support alongside the core license — these usually make up a significant share of first-year spend.

  • Insurity's presence in Celent's 2023 North America P&C policy administration report placed it among 19 profiled vendors; the three XCelent awards (Advanced Technology, Breadth of Functionality, Customer Base and Support) went to Guidewire PolicyCenter that cycle.
