Do you have E3/E5 to qualify for the Intune Suite rollout due in Q3? I'm hoping the majority of apps, we've still got in SCCM, will be in Microsoft's Enterprise App Catalogue and we can just switch to those. It should be low effort, and they should be maintained for us moving forward. "No more packaging" is the dream.

I don't think there's a maintained public catalogue listing. I found someone sharing an outdated listing but that was it.

Otherwise, you might consider a third-party service like Patch My PC.
