Is BITS Services used by bigfix during patching

We have a issue with one of the security patch for windows, this patch is getting failed while we are applying it on the endpoint with message “download failed”, while checking on the endpoint a process is initiated on BITS (Background intelligence transfer service) services for windows that is trying to download that patch from internet (and obviously it fail as we not have internet on the machine).
Does bigfix use the BITS services also while we are applying patches on the endpoints because as per my understanding it will only use besclient and windows update service to push the patches on the endpoints?
Does besclient under any circumstances create process on BITS service?

No. BigFix doesn’t use BITS for any internal processes.

It is possible to deploy scripts, via BigFix, that use BITS. But BigFix by itself doesn’t use BITS.
