If you are familiar with System Center Configuration Manager there is no doubt that you know our Patch Management is second to none and we have made great strives in the 3rd party patching space as well. Below is a list of update catalogs i have found and used over the years. By no means is this a fully comprehensive list but a starting ground. If you have other catalogs you are aware of post them in the comments section and we can get the list updated with additional entries so we can all benefit from a central location to find 3rd party catalogs.

Now hunting down all of these catalogs is fun and all but if you want full 3rd party update support without all of the hassle and a boat load of additional features to manage your application lifecycle i would highly recommend heading over to patch my pc and taking a look at what they have to offer.
