Hey Windows Pros,
I work as a tech-marketer for ManageEngine. We have some exciting news from Patch Connect Plus, which I thought will be valuable to you.
We have introduced "Standard edition" which offers third-party software catalogs to your SCCM 1806. These catalogs can also be used to publish to SCUP too. So if you'd like to avail a free trial and see how it works on your SCCM environment, you can get started here.
Here's a list of applications supported: https://www.manageengine.com/sccm-third-party-patch-management/supported-applications.html
You can learn how to add the third-party catalogs to SCCM from the video:
You can write to firstname.lastname@example.org if you would like to avail an extension of the free trial(30 days default)/avail more applications under the Standard edition for catalogs.
Happy to help.
