Very Secure IT department - storyline 360

Hi! I work for a company with very strict IT security. I can't install anything without their permission and each version of software needs to be tested vigorously before being added to the system image.

Here's the issue: As I understand it, I need Articulate 360 to install storyline 360, right?

The version of Articulate 360 provided by IT was very old and consequently Articulate 360 prompted me to update. I wasn't allowed to due to the aforementioned IT policy. IF I can get IT to validate your latest version of Articulate 360 and storyline 360 what will happen next time there is an update to Articulate 360? I won't want to update all the time as I have to involve IT. It seems Articulate 360 is updated quite often whereas storyline 360 isn't. I just need storyline 360. Can I say no to updates from Articulate 360 or will storyline 360 cease to be available if I do that?

What is the proper approach and what are the ramifications of not constantly updating Articulate 360?

Many thanks!
