Upstream vendor outages may involve limited communication and need escalation
Service expertise can be costly
Project delivery or troubleshooting may be slower or difficult initially

Guardian fit considerations

Mobile platform specifics (iOS/Android) and hardware kiosk requirements are not specified on the overview page
Public site does not publish standard pricing or explicit platform hosting regions, so total cost and data residency details will be part of procurement discussions
