What should I get to create PDF with DRM?

[Guest]

    As an editor, I need to get published some digital books in both PDF and EPUB file formats. I want to protect them with the DRM system too. On this website, I found some information about your Adobe Content Server, but I can't find the necesary information for adquiring this product in Spain. Is it possible?

Thanks in advance.
