DotActiv requires permanent remote access for ongoing support purposes. However, long-term, it's not necessary.
During the first few months, DotActiv actively monitors the integration to ensure it is stable and running smoothly.
Should there be any issues, DotActiv can immediately go onto your server and diagnose the problem.
You can restrict DotActiv's access to the server if you prefer to go this route. In that case, DotActiv complies with any security policies you have in place.
Please note, during the initial implementation, DotActiv requires permanent access because otherwise, the process to get everything up and running is difficult.
