Security alert aggregator?

[David Hubbard <dhubbard () dino hostasaurus com>]

Curious if anyone knows of a security alert aggregation service?  For example, go and plug in all the various vendors 
hardware and software packages your enterprise uses, and then the service subscribes to all the random RSS feeds, CVE 
lists, vendor mailing lists, etc. to feed you the data instead of needing staff to write something custom, and then 
have checks to ensure the custom thing is still pulling from the right location, etc.

Thanks
