Question

Does Vantage On-Prem need any outbound ports open before you can start using it?

Answer

No, you can start using Vantage right from the get-go, but in some specific circumstances the only needed one is the HTTPS (443) port for the following cases only:

• To https://vantageonprem.azurecr.io - prior to installation for pre-downloading of the Vantage containers
• To https://licensing-us.abbyy.com - during runtime, for synchronizing tenant's subscription/license information
