You cannot avoid this unless you distribute an application via the App Store   You get this message because the application is signed via an enterprise certificate that has not yet been trusted by the user  Apple force this prompt to appear because the application that is being installed hasn t gone through the App Store review process so is technically untrusted   Once the user has accepted the prompt  the certificate will be marked as trusted and the application can be installed  along with any other future applications that you wish to install that have been signed with the same certificate   Note  As pointed out in the comments  as of iOS 8  uninstalling all applications from a specific certificate will cause the prompt to be shown again once an application from said certificate is re-installed   Here is the link to Apple website that confirms this info  https   support apple com en-us HT204460

If you push it out through MDM it should auto-trust the application  https   support apple com en-gb HT204460   but it still has to verify the certs etc with Apple to ensure they ve not been revoked etc i presume  I had this message preventing the application from launching and it was only when the proxy information was configured so it i could use the internet that it went away after a couple more launch attempts

You absolutely can avoid this issue if you manage the device with MDM or have access to Apple Configurator    The solution is to push either the Developer or iOS Distribution certificate to the device via MDM or Apple Configurator  Once you do that  any application signed by that cert will be trusted   When you click on  Do you trust this developer   you re essentially adding that certificate manually on a per-app basis
