Updates for an enterprise's software product are made available to user devices on-line, even when network resources of the enterprise are unavailable. Software update sets and notifications concerning the update sets may be published by an enterprise for consumption by content distribution partners of the enterprise and parties not affiliated with the enterprise. Each abstraction relating to an update, including update notifications and update sets may include a cryptographic signature for later use in authenticating the source of the abstraction. Update notifications also may include information indicative of: available update sets; and network locations at which the update sets can be accessed. Further, an update notification may be configured with a time-to-live (TTL) value indicating a value of time after which the notification expires. TTL values give the enterprise some control over the distribution of update sets by limiting the lifespan of the update notifications corresponding to the update sets.
