Scenario
You wish to understand which ports and URLs are required for the Signature 365 web portal, add-in and agent to function.
Solution
All Signature 365 services connect via port 443, using TLS 1.2 or higher.
We recommend allowing *.signature365.com to account for any future additions or changes to the configuration requirements.
