When an administrator sets apolicy(such asData Policies) that applies toall data entered into ServiceNow, it runs on theserver-side.
Why Data Policies Run on the Server?Data Policies apply to all data sources:
UI forms
Import Sets
Web Services (APIs, integrations)
Enforces field validation at the database level
Ensuresdata consistencyacrossall entry points.
Reducesclient-side dependencyfor validation.
Applies uniformly regardless of how the data is entered
UnlikeUI Policies(which only work on forms),Data Policiesensure field rules are enforcedeverywhere.
A. Network →Incorrect
Policies are not enforced at thenetwork level.
They operate within theServiceNow application.
C. Client →Incorrect
Client-side scripts (likeUI Policies or Client Scripts)onlyenforce validation within the browser.
Data Policies run at the server level, ensuring broader enforcement.
D. Browser →Incorrect
While UI Policies and Client Scripts run in the browser,Data Policies are applied on the server.
