# List of commercial products based on Red Hat Enterprise Linux

There are a number of commercial products based on Red Hat Enterprise Linux (RHEL). Information about these products and the version of RHEL they are based on is often difficult to come by, since this fact is not widely publicised. Sometimes it is possible to run the 'uname -r' command to get the kernel release and then cross-reference it with the RHEL version history.
