Progeny has positioned themselves as a Platform Services company. The idea is that everyone's needs are different, as a result there will be variations in "platform" from customer to customer. Progeny develops a "platform" for a customer which can then be managed vi APT.

They support both RedHat and Debian based distros.
recently they announced support for Red Hat Linux 7.2 and 7.3 (which Red Hat themselves has retired)

If it means anything, they provide Platform Services work Hewlett Packard.
