yum-security for CentOS?

Last time I checked I was able to install yum-security in CentOS but since it doesn't use the official redhat mirrors I was unable to get it to actually work. Is there a way to make yum-security work or is there an alternative to yum-security on CentOS?

For Centos 6, Centos 7 and Centos 8 the easiest way is to use Steve Meier's Updateinfo: a yum repository with CentOS Errata information.

It's a ready yum repo served and updated by the author of the CEFS project.

It is a paid service but as of now it costs only a mere $3 per month for an unlimited number of servers (but using a mirror for a big fleet is recommended).

Note that it's the same thing as you can do yourself according to dsmsk80's answer here. But don't you prefer to support the enthusiast who made this solution possible instead? :)
