I got the message when starting MacOS 11 that some software was blocked when loading. I opened the system preferences, navigated to privacy, unlocked preferences and put checkmarks next to the software that was blocked. It said the mac had to restart but how do I know that what I did was effective. It still says "Some system software was blocked when loading." All items are now checked. How do I know it worked.

Also it would be helpful if the program the software is part of could be named. Now it only states the company. While I don't know if that part is crucial for some of my applications, would make sense to state them next to company. Googling the companies does not always gives an answer.

The phrase "system software" usually means kernel extensions (drivers, in Windows-speak), so the place to look would be System Information > Software > Extensions. Having seen this before, it's likely you're using policy-restricted extensions which would have (or did) present warnings in Catalina. These are now deprecated, and while a boot argument can be used to reenable them in the beta, they will likely be permanently disabled in the release.
The list of extensions will indicate which aren't loadable (look for Unsupported, and not from Apple), and you'll find that the list to be enabled in System Preferences excludes these. The way it currently works is all third party extensions get rebuilt in a collection (documented in kmutil(8)), so everything gets retriggered.
